COVID-19

The Group's priority in 2020 was, and continues to be, to safeguard its employees, contractors and surrounding communities from COVID-19. The implemented measures include thermal screening, X-ray screening, Rapid Anti-body and Anti-gen Diagnostic screening and Polymerase Chain Reaction (PCR) testing, promotion of sanitation measures, appropriate social distancing, compulsory wearing of face masks and the provision of Personal Protective Equipment. As part of the COVID-19 management strategy, all suspected positive cases are safely transferred to their respective residences, or national health facilities if determined medically necessary, for quarantining, thus limiting suspected positive cases on mine site.

Commenting on the results today, Clifford Elphick, Chief Executive Officer of Gem Diamonds, said:

"Gem Diamonds has delivered positive operational and financial results during a very challenging year. Our first priority remains the safety of our employees, contractors and surrounding communities and we have taken steps to support the Lesotho Government in securing COVID-19 vaccinations for our workforce and surrounding communities.

The operational results were characterised by strong cash flows, the achievement of all revised operational metrics and the recovery of 16 diamonds greater than 100 carats each, the highest number recovered in a single year. The stronger prices achieved in the second half of 2020, reaffirms the recovery of the diamond market and the unique quality of the Letšeng production.

The Group has proven its ability to respond to an unprecedented global crisis in an agile and effective manner. This, together with the cost containment and cash preservation initiatives implemented, positions the Company well for the ongoing recovery of the diamond market in the coming years.

We are pleased to announce that based on the results achieved in 2020, the Board has recommended the payment of an ordinary dividend of 2.5 US cents per share."

The Company will host a live audio webcast presentation of the full year results today, 11 March 2021, at 9:30 GMT. This can be viewed on the Company's website: www.gemdiamonds.com

ABOUT GEM DIAMONDS:

Gem Diamonds is a leading global diamond producer of high value diamonds. The Company owns 70% of the Letšeng mine in Lesotho. The Letšeng mine is famous for the production of large, top colour, exceptional white diamonds, making it the highest dollar per carat kimberlite diamond mine in the world.

CHAIRPERSON'S STATEMENT

"The Group moved swiftly and resolutely during extremely challenging and uncertain circumstances."

- Harry Kenyon-Slaney -

Dear shareholders,

On behalf of the Board, it gives me great pleasure to present the Gem Diamonds Annual Report and Accounts 2020. The Report and Accounts provide an overview of the progress we have made in delivering on the Group's strategic objectives in a year when the economic, social and personal lives of so many people and organisations have been profoundly affected by the COVID-19 pandemic.

OUR VISION:

To support, develop and empower our employees so that they can benefit and develop in a company of which they are proud, we can make a meaningful, sustainable contribution to the countries and communities in which we operate and deliver sustainable value to our shareholders.

Since its emergence as a problem of global significance in early 2020, the COVID-19 pandemic has demanded an enormous amount of management time and effort. Our primary objective has been to ensure the safety and health of our employees, their families and the communities surrounding our operations as well as making a material contribution to Lesotho's national effort to contain the spread of the virus. In parallel, however, it was imperative that economic activity continued and we devoted extensive efforts to ensuring that our Letšeng operation, which is a significant earner of foreign currency in Lesotho, was able to restart operations safely and in line with the strict guidelines implemented by the government. This twin-track approach of contributing meaningfully to local priorities while continuing to operate the Letšeng mine directly aligns with our corporate vision.

Despite the prolonged absence of certain required skills and individuals during the lockdown, our operational teams made important decisions while running a complex and technically demanding process. Their ability to take responsibility and act autonomously is testament to the work we have done to develop and empower our people. As it unfolded, the continued impact of the pandemic required management to take urgent and decisive action and make critical and difficult decisions across the Group to control costs, continue operations in a responsible and safe manner and stabilise the business. We are extremely grateful to the significant proportion of the workforce who agreed to take a material but temporary salary cut, with no decrease in motivation, to support cash preservation in the Group. Following the positive sales results and cash flow generation in September, we were able to repay these salary cuts at an effective rate of 96% to all affected employees.

DIAMOND SUPPLY/DEMAND FUNDAMENTALS SUPPORT HIGHER PRICES

While there was significant uncertainty regarding the impact of COVID-19 on the diamond market at the start of the pandemic, apart from a relatively short initial period, demand for diamonds returned and prices achieved remained relatively strong. Supply has been affected by the closure of Rio Tinto's Argyle mine, operational and COVID-19-related production interruptions in various major producers during the year, and the closure of some smaller mines. China has emerged from the pandemic well and continues to show signs of a return to strong economic growth. Rising living standards will continue to support China's growth as a significant consumer of diamonds and especially of the large high-value diamonds produced by Letšeng. US stock markets, long seen as closely correlated with diamond demand, performed well; and this supported the progressively more positive economic outlook as the year drew to a close. India will emerge as an important polished diamond consumer market in the medium to long term and the manufacturing sector is emerging from its COVID-19-related challenges.

CONTRIBUTION TO COMMUNITY AND COUNTRY

At Gem Diamonds we regard ourselves as guests in the countries where we operate and we endeavour at all times to maintain strong and constructive relationships, both with the populace and with regional and national governments. We engage with government and local communities on a regular basis to seek mutually beneficial solutions to challenges that arise. We work closely with these communities, providing both financial and practical support on a range of projects they consider important.

MAIN AREAS OF FOCUS FOR THE BOARD IN 2020:

1. Ensuring sustainable operations, keeping employees and local communities safe and supporting the Lesotho Government during COVID-19.

   2.     Ensuring delivery of the objectives of the BT programme. 
   3.     Enhancing risk management systems and processes. 
   4.     Maintaining disciplined financial control to increase cash generation and repay debt. 
   5.     Considering an appropriate return to shareholders. 

GOVERNANCE TO SUPPORT SUSTAINABLE VALUE CREATION

The Group's governance systems and processes performed well during the year. While face-to-face contact tends to lead to deeper discussions of issues during and around Board meetings, the remote interaction necessitated by COVID-19 nevertheless proved effective. We have increased the time allocated for the quarterly Board and Committee meetings to allow for longer discussions, which facilitates a deeper understanding of the issues. In addition, the Board added a stand-alone quarterly risk review meeting to ensure time is available for a detailed review and discussion of the Group's key risks and to test management's mitigating actions.

The appointment of an experienced non-Executive Director to take responsibility for engaging with stakeholders in Lesotho has proven beneficial. Mazvi has deep local knowledge of political, social and community issues in Lesotho and the feedback from her engagement with employees provides valuable feedback to the Board to inform our decision-making.

SAFE AND RESPONSIBLE OPERATIONS

Workplace safety is an absolute priority for the Board and management. We passionately believe it is possible for every employee to come to work and return home safely every day and we are constantly looking at improving our safety systems and processes to ensure this is achieved. We are pleased with the improvement in safety performance this year.

The Board is similarly strongly committed to environmental responsibility and I am pleased to report that there were no major or significant environmental incidents reported at any of our operations during the year. Gem Diamonds' inclusion in the FTSE4Good index recognises the high standards of environmental, social and governance practices in place.

During the year we launched the first rolling three-year cycle to further integrate the UN Sustainable Development Goals (SDGs) into the Group's systems and processes. The project aims to embed the objectives of the goals in our decision-making and thereby further enhance Gem Diamonds' positive impact in line with relevant UN recommendations.

GENERATING SUSTAINABLE RETURNS FOR OUR SHAREHOLDERS

The focus on cash generation and preservation during the year saw the Group move from a net debt position of US$10.2 million at the start of the year to a net cash position of US$34.6 million at year end. While some of the longer-term development capital expenditure was postponed, this represents a prudent approach to expenditure in a time of heightened uncertainty.

In line with our commitment to delivering sustainable shareholder returns, the Board's policy is to pay a dividend to shareholders when the financial strength of the Group permits.

As a result of the Group's strong cash generation during the year and improved financial position, the Board is pleased to recommend that a dividend of 2.5 US cents be declared in respect of the 2020 financial year. The Board is committed to sustaining shareholder value through the implementation of appropriate dividend policies.

OUTLOOK

Although the supply/demand dynamics of the diamond market remain positive, particularly for the unique high-value diamonds produced at Letšeng, our immediate concern remains the ongoing protection of our people from the COVID-19 pandemic, which continues to cast a shadow over southern Africa. Our immediate priorities for 2021 therefore remain the provision of a safe operating environment for all our employees and support to the Lesotho Government in securing vaccines for our workforce and local communities.

The work we did in prior years to reduce costs, lower overheads, streamline systems and improve efficiencies stood us in good stead in 2020 and has provided an excellent foundation for the year ahead. We will build on this momentum and make the most of the opportunities we have created through the BT and CI programmes. In addition, we need to unlock the commercial potential in the pioneering work being done to reduce diamond damage through our technology and innovation projects and to advance the use of blockchain technology in providing a full and transparent record of origin for every diamond produced at Letšeng.

FINAL REMARKS

I would like to thank my fellow Board members for their valuable and extensive contributions during the past year. On behalf of the Board, I would also like to thank our long-standing partners at Letšeng, the Lesotho Government, and the leaders of our host communities, all of whom have helped us to navigate what has been a challenging year.

The Group's management and employees deserve a special note of appreciation for their commitment and tenacity during 2020. The Group moved swiftly and resolutely during extremely challenging and uncertain circumstances to contain the spread and impact of a devastating pandemic that could have had an equally devastating impact on our business. I have been tremendously impressed by the resilience and capability of management and employees throughout the organisation to run a technically, commercially and physically complex business, often with remote leadership.

I want to extend my condolences to the families and friends of colleagues who have lost loved ones as a result of the pandemic or related complications. The COVID-19 pandemic is far from over and, at the time of writing, things continue to be extremely difficult in southern Africa. Until vaccinations have been rolled out to a large part of the population, we must remain extremely vigilant.

PRINCIPAL RISKS AND UNCERTAINTIES

HOW WE APPROACH RISK

The Group's risk management framework aims to identify, manage and mitigate the risks and uncertainties to which the Group is exposed. Effective risk management and mitigation reduce the likelihood that financial, operational and compliance impacts could materially affect the Group's performance, reputation and long-term growth.

The risk management framework combines top-down and bottom-up approaches with appropriate governance and oversight, as shown in the table below.

Prior to 2020, risk was an agenda item in Board meetings, but from the start of 2020 a stand-alone risk review meeting was added to the quarterly Board and Committee meetings to allow sufficient time to explore the risks fully and to assess management's scenarios and plans. The Board reviews the risk register and interrogates the most critical risks in detail, debating mitigating plans with management.

Risk Management Framework

The Board and its Committees have identified the most material risks facing the Group, including strategic, operational and external risks, both current and emerging. These risks are actively monitored and managed as their impact, individually or collectively, could affect the Group's ability to operate profitably and generate positive cash flows in the medium to long term. The risk disclosures follow guidelines from the IIRC's <IR> Framework to clarify the distinction between inherent and residual risk, indicate risk movements, and link the areas of the business model and strategy to each risk.

While Gem Diamonds' risk management framework focuses on risk identification and mitigation, many factors that give rise to these risks also offer opportunities. The Group monitors existing and emerging opportunities and incorporates them into the strategy where they support the Group's vision.

How COVID-19 made us re-evaluate risk

COVID-19 has increased the emphasis on identifying the possible implications of external macro risks and low-probability/high-consequence events to inform appropriate contingency plans. These risks can be mitigated by ensuring we continue to build resilience and flexibility into our leadership and operational processes and our leaders are equipped to quickly quantify the size and scale of the emerging issue and adapt accordingly.

Insurance cover is an important aspect of risk mitigation. It transfers potential financial implications due to any primary risk of the Group materialising. The COVID-19 pandemic led to an increased risk perception in the insurance market as a result of increasing claims and a declining premium pool. Insurers have decreased their exposure to the mining industry. As a result, the renewal of appropriate insurance has become challenging leading to additional exclusions, reduced cover, increasing deductibles/excesses payable and increasing premiums.

Although insurance cover does not eliminate the operational controls needed to manage and mitigate risk, it offsets the potential financial loss should the risk materialise. Reduced cover consequently directly impacts the Group's cash management risk.

The Group is considering various options to minimise risk in the absence of insurance cover, including a self-insurance structure and enhanced business continuity procedures.

EMERGING RISKS

The assessment of emerging risks is embedded within the risk management function of the Group. Emerging risks identified during these assessments are reported to the subsidiary boards on a structured quarterly basis and to the corporate office as they are identified.

Management evaluates emerging risks and presents them to the Board for consideration and evaluation.

Emerging risks are risks that:

   --      are likely to materialise or impact over a longer time frame than existing risks; 
   --      do not have much reference from prior experience; and 

-- are likely to be assessed and monitored against vulnerability, velocity and preparedness when determining likelihood and impact.

The current emerging risks on the Group's radar are:

   --      lab-grown diamonds (16); 
   --      generational shifts in consumer preferences - social influencers (17); 
   --      the rate of advancement of digital technologies such as blockchain (18); and 
   --      future workforce (automation, skills for the future, etc.) (19). 

VIABILITY STATEMENT

The Board has assessed the viability of the Group over a period significantly longer than 12 months from the approval of the financial statements in accordance with the UK Corporate Governance Code. The Board considers three years from the approval of the financial statements to be the most relevant period for consideration for this assessment, given the Group's current position and the potential impact of the principal risks documented on pages 25 to 35 that could impact the Group's viability.

While the Group maintains a full business model, based predominantly on the life of mine (LoM) plan for Letšeng, the Group's annual business and strategic planning process also uses a three-year time horizon. This process is led by the CEO and involves all relevant functions including operations, technology and innovation, sales and marketing, finance, treasury and risk. The Board participates in the annual review process through structured Board meetings and annual strategic sessions. A three-year period provides sufficient and realistic visibility in the context of the industry and environment in which the Group operates, even though the LoM, the mining lease tenure and available estimated reserves exceed three years.

The business and strategic plan reflects the Directors' best estimate of the Group's prospects. The Directors evaluated several additional scenarios to assess the potential impact on the Group by quantifying their financial impact and overlaying this on the detailed financial forecasts in the plan.

The Board's assessment of the Group's viability focused on the critical principal risks categorised within the strategic, external and operational risk types, together with the effectiveness of the potential mitigations that management reasonably believes would be available to the Company over this period.

The Group's credit facilities (excluding project term loans) total US$70.8 million when fully unutilised, with US$34.0 million expiring on 18 July 2021, US$30.0 million expiring on 31 December 2021 and the balance of US$6.8 million being a general banking facility with no set expiry date (refer Note 18, Interest-bearing loans and borrowings). The Group's viability assessment assumes that these facilities will be successfully restructured, and their expiry dates extended, based on advanced discussions with lenders and previous successful renewals.

COVID-19

Uncertainty exists around the ongoing impact of the pandemic on the Group. The Group is in a good position to mitigate the impact of any operational disruption that may be caused by potential further COVID-19-related lockdowns. International travel restrictions could have an impact on the frequency of diamond tenders and the ability to generate revenue on its regular tender cycles.

STRESS TESTS

The scenarios tested considered the Group's revenue, EBITDA(1) , cash flows and other key financial ratios over the three-year period. The scenarios tested included the compounding effect of the factors below and were applied independently of each other.

The Group's current net cash(2) position of US$34.6 million as at 31 December 2020 and available facilities of US$60.8 million would enable it to withstand the impact of these scenarios over the three-year period. This position is supported by the cash-generating nature of the Group's core asset, Letšeng, and its flexibility in adjusting its operating plans within the normal course of business.

Based on the robust assessment of the principal risks, prospects and viability of the Group, the Board confirms that it has a reasonable expectation that the Group will be able to continue in operation and meet its liabilities as they fall due over the three-year period ending March 2024.

CHIEF EXECUTIVE'S REVIEW

"In the face of the significant disruption caused by COVID-19, the fundamentals of Gem Diamonds' business remain sound and our strategy intact."

- Clifford Elphick -

In the face of the significant disruption caused by COVID-19, the fundamentals of Gem Diamonds' business remain sound and our strategy intact. Despite the extreme uncertainty at the start of the pandemic the fast and decisive action we took, combined with the organisational improvements of the last few years and strong stakeholder relationships, supported a good operational performance, strong cash flows and an improved financial cash position at the end of the year.

Our first priority was to make sure our people were safe. We took the potential threat to their health extremely seriously and acted quickly to do what we could to protect them, which included immediately establishing a testing laboratory on site at Letšeng.

Following the Lesotho Government's lockdown order, as soon as it was safe to restart operations and we had the necessary authorisations, we worked hard to get back to full production as fast as we could. We managed to ramp up well ahead of many operations in similar positions, greatly reducing the loss of production. This success was in no small part due to the in-country skills and expertise we have developed at Letšeng, since certain required skills and individuals were unable to be physically at the mine.

The quick return to production, Letšeng's top-quality diamonds and our excellent relationships with our customers allowed us to sell diamonds and generate revenue when many other producers could not. Despite the pressure on the diamond market, these factors helped us to achieve a 17% higher overall average price per carat than in 2019.

Most of the BT cost-efficiency initiatives are now fully embedded in day-to-day operations and the CI initiative is being rolled out. The changed working conditions during COVID-19 and extensive engagements with our contractors and suppliers identified additional efficiencies and new ways of working that helped to further reduce costs, which contributed to strong operating cashflows. It is pleasing to announce that the Board has recommended a dividend of 2.5 US cents per share.

While we are pleased with the Group's performance for the year in the face of these challenges, we are deeply saddened and offer our condolences to the families of the seven employees who passed away to date from suspected COVID-19-related complications.

STRATEGIC FOCUS: WORKING RESPONSIBLY AND MAINTAINING OUR SOCIAL LICENCE

The Group's COVID-19 response included a significant contribution to ensuring the health of members of surrounding communities and supporting the Lesotho Government's programmes, as described on page 50.

We aim to create and sustain a workplace safety culture that is underpinned by a deep sense of mutual care and collaboration across the workforce. We are pleased with the improvement in our safety statistics this year but remain diligent in implementing our safety protocols in line with our commitment to promoting a culture of zero harm and responsible care. There were no fatalities and one LTI during the year, compared to one fatality and seven LTIs in 2019. The Group-wide LTIFR decreased to 0.04 (2019: 0.28) and the lowest AIFR in a decade was recorded.

Our strategic focus on working responsibly includes our commitment to environmental responsibility, which is discussed in detail on pages 48 to 50. A rigorous ongoing monitoring and management programme is in place to ensure any risks regarding Letšeng's freshwater dam and two tailings storage facilities (TSFs), which are designed and managed to international best practice, are timeously identified and mitigated. We are currently assessing our TSF management process against the Global Industry Standard on Tailings Management launched in August 2020 and developing an action plan to ensure conformance. A technical visit to the mine was undertaken in November 2020 by an independent expert and the compilation of a draft Independent Tailings Review Board (ITRB) structure and Terms of Reference is underway.

Supporting local communities and contributing to national priorities

Gem Diamonds invests in surrounding communities to improve educational outcomes, develop infrastructure and stimulate local enterprises to create self-sustaining employment independent of the mine. Some of these projects were delayed due to disruptions caused by COVID-19 and we continue to engage with stakeholders regarding project status, any further COVID-19 impact on progress and alternative projects to address immediate needs in current circumstances.

In addition to community support, the Letšeng mine makes a substantial contribution to the Lesotho economy, providing jobs for more than 1 702(1) people and supporting the local economy and the broader population of Lesotho through local procurement initiatives. In 2020, due to the reduced production and the 30-day shutdown period, in-country procurement decreased 23% to US$126.9 million (2019: US$164.6 million), of which US$2.2 million was procured directly from PACs (2019: US$2.4 million) and US$27.4 million (2019: US$30.5 million) from regional communities around Letšeng. The Company's investment in training also improves individual skills in the area.

No major or significant stakeholder incidents were reported at any of Gem Diamonds' operations during the year (2019: none) and there were also no incidents involving any violation of the rights of the indigenous people on whose land the Group operates (2019: none).

STRATEGIC FOCUS: EXTRACTING MAXIMUM VALUE FROM OUR OPERATIONS

Despite the challenging operating environment, Gem Diamonds produced solid results that included the recovery of 16 diamonds greater than 100 carats (2019: 11). Exceptional recoveries during the year include a 439 carat white Type IIa diamond, a 183 carat white Type IIa diamond and a 166 carat white Type IIa diamond reaffirming the quality of the mine's production.

While the overall diamond market was under extreme pressure, our proactive steps to ensure the safety of customers and provide additional analysis of the diamonds on tender resulted in the average price achieved increasing 17% to US$1 908 per carat (2019: US$1 637 per carat) from the sale of 99 172 carats (2019: 111 292).

Tonnes treated for the year decreased 19% year on year impacted by the 30-day shutdown at Letšeng and subsequent phased ramp-up of the two plants and we continue to focus on enhancing value over volume in our treatment of ore through the plants. Carats recovered decreased 12% to 100 780 (2019: 113 974), which was in line with the reduced tonnes treated due to the COVID-19-related shutdown in Q2. Letšeng's operational performance is discussed in detail on page 43.

Revenue increased 4% to US$189.6 million (2019: US$182.0 million), which translates to underlying EBITDA(2) of US$53.2 million and earnings per share of 9.8 US cents. Cash flow was a key focus given the crisis conditions prevalent for most of the year and cash flow from operations increased 73% to US$96.2 million for the year, allowing the Group to move from a net debt position of US$10.2 million at the start of the year to a net cash(3) position of US$34.6 million at the end of 2020. More information regarding the Group's financial results is available in the Chief Financial Officer's report on page 36.

The process to sell the Ghaghoo mine, which remains on care and maintenance, continues, but was significantly delayed during the year due to the impact of COVID-19. Management remains committed to the sale and will conclude the process in 2021.

3 Net cash/(debt) is a non-GAAP measure and calculated as cash and short-term deposits less drawn down bank facilities (excluding the asset-based finance facility and insurance premium financing).

STRATEGIC FOCUS: PREPARING FOR THE FUTURE

The Group's improved balance sheet at year end provides a sound platform from which to navigate the current uncertain environment. The reduced costs and improved efficiencies realised through the BT initiatives were critical in maximising operational cash flows during the year and the operational benefits from the CI initiative currently being rolled out are already evident. These initiatives are discussed on page 46.

Non-essential capital expenditure was deferred wherever possible to preserve cash, but not at the expense of projects necessary to sustain operations.

We continue to advance two key technologies to identify locked diamonds within kimberlite and to liberate diamonds using a non-mechanical process. While the pilot project was hindered largely by the COVID-19-related lockdown and travel restrictions and did not make the progress during the year we would have liked, we have identified new technical partners to advance the pilot and believe that the benefits in reduced diamond damage and lower operating costs will be realised in time.

Gem Diamonds is cognisant of the risks presented by climate change and conscious of the need to minimise emissions and our environmental impact more broadly. The immediate climate-related challenge at Letšeng remains water management. Effective water management is crucial for the viability of our business. This refers not only to the preservation of natural resources for the benefit of host communities but also to the cost implications of water consumption on our business.

OUTLOOK

In the year ahead, our immediate focus will be on ensuring the health of our employees and contractors during the COVID-19 second and possible future waves. We will also continue to support surrounding communities and assist the Lesotho Government in its efforts to manage the impact of the pandemic, including doing what we can to facilitate access to effective vaccination programmes.

At an operational level, we will continue to realise the benefits of the BT programme and roll out the CI project, drive efficiencies and cost-reduction initiatives to maximise cash flows and maintain our status as a responsible, safe and low-cost operation.

APPRECIATION

I would like to thank the Board and our Chairperson for their support and guidance during the year. A special thanks goes to the management teams for their energy and tenacity in implementing the strategy in extremely challenging conditions.

My appreciation also extends to the Lesotho Government for its help in allowing us to restart our operation. Our customers bought our product at good prices during uncertain times and we thank them for their support and trust. In closing, thank you to our shareholders for their confidence and belief in our vision.

CHIEF FINANCIAL OFFICER'S REVIEW

"Management was able to normalise operations and maintain cash reserves through effective sales processes and cash preservation initiatives."

- Michael Michael -

FINANCIAL OVERVIEW 2020

The Group's immediate focus in the first half of the year was to manage the severe operational challenges brought on by the swift onset of the COVID-19 pandemic. Management was able to normalise operations and maintain cash reserves through effective sales processes and cash-preservation initiatives. in the short to medium term the focus moved to optimising cash generation through further operational efficiencies to ensure the continued sustainability of the business in a challenging environment.

Significant operating and capital cost reduction and deferment measures were implemented in the second quarter which, together with the ability to successfully hold tenders and generate revenue, contributed to positive cash generation. Following the forced shutdown of operations at Letšeng due to the Lesotho Government's lockdown order in March and April, planned waste mining activities was successfully deferred to resume in July; and in the second half of the year the primary focus was on continued and safe operations, curbing the spread of COVID-19 on site and cash generation.

Although tender revenues initially tracked the weaker market for rough diamonds following the onset of COVID-19, there was a marked improvement in sentiment in the second half of the year. With the focus on the higher-value satellite ore, Letšeng produced good high-quality large diamonds, which included 16 diamonds greater than 100 carats during the year, compared to 11 in 2019.

Underlying EBITDA(2) from continuing operations increased to US$53.2 million (after COVID-19 standing costs of US$3.9 million incurred during the lockdown period) from US$41.0 million in 2019. Profit attributable to shareholders from continuing operations for the year was US$16.9 million, equating to earnings per share from continuing operations of 12.1 US cents on a weighted average number of shares in issue of 139.3 million. After including the loss of US$3.3 million from the Ghaghoo discontinued operation, the Group's attributable profit was US$13.6 million with earnings per share after discontinued operations of 9.8 US cents.

The Group ended the year with a cash balance of US$49.8 million and drawndown facilities of US$15.2 million, resulting in a net cash position of US$34.6 million (2019: net debt of US$10.2 million) and unutilised available facilities of US$60.8 million.

Revenue

Revenue of US$189.6 million was generated at Letšeng, achieving an average price of US$1 908 per carat(1) (2019: US$1 637 per carat). The Group sold 34 diamonds for more than US$1.0 million each, contributing US$77.6 million to revenue.

The Group's increased revenue was mainly driven by achievement of a higher average price per carat and increased large diamond recoveries.

Expenditure

Operating expenditure and COVID-19 standing costs

Group cost of sales decreased by 9% to US$104.7 million from US$114.7 million in 2019 as a result of the cash preservation measures and the continued focus to reduce costs in line with the BT initiatives. Total waste-stripping costs amortised were US$43.4 million compared to US$43.1 million in 2019.

Certain standing charges that were incurred during the shutdown and ramp-up periods where normal waste stripping and carat production levels were disrupted , were recognised as abnormal costs, and in terms of IAS 2 Inventories have been expensed immediately and disclosed separately from cost of sales. These costs amount to Lesotho loti LSL48.5 million (US$2.9 million). In addition, US$1.0 million was incurred to implement protocols to address the risk and contain the spread of COVID-19 at the operations and Letseng's surrounding communities.

Total operating costs in local currency increased by 6% to LSL1 740.8 million compared to LSL1 649.6 million in 2019 and includes the impact of non-cash accounting charges. The unit cost per tonne increased 30% to LSL320.20 per tonne from LSL245.92 per tonne treated in 2019. This increase was driven by the reduced tonnes treated and the proportionate mix of ore mined during the year. Although the total waste-stripping costs amortised during the year was similar to 2019, the increased contribution from Satellite pipe material (which carries a higher stripping ratio and associated amortisation charge) impacted the unit cost. During the year, 2.8 million tonnes of this material were treated (2019: 1.6 million) which increased the total amortisation charge to LSL131.56 per tonne treated compared to LSL92.88 in 2019. The increase in the non-cash accounting charges per tonne treated, impacted by waste-stripping amortisation, was offset by the timing differences of the inventory and stockpile movements during the year.

Direct cash cost per tonne treated is LSL201.46, representing an 11% increase from 2019. Waste cash cost per waste tonne mined increased by 13% to LSL43.70 (2019: LSL38.62). These cash cost increases are a direct result of the lower volumes treated (5.4 million tonnes compared to 6.7 million tonnes in 2019) and waste tonnes mined (15.6 million tonnes compared to 24.0 million tonnes in 2019) during the year respectively. Total direct cash costs, including waste cash costs, decreased by 18% to LSL 1 775.7 million from LSL2 158.8 million in 2019 as a result of the lower volume of mining activities and cash preservation and deferment measures implemented during the year.

Letšeng pays the third plant operator contractor according to the revenue generated by the sales from diamonds recovered through the contractor plant. In 2020, the cash costs in local currency decreased by 23% in line with the reduction in carats recovered and sold.

BT and CI associated costs of US$0.6 million were incurred relating to initiatives implemented during the year, resulting a unit cost impact of LSL1.79 per tonne treated.

Exchange rate influences

Revenue is generated in US dollars, while the majority of operational expenses are incurred in the relevant local currency in the operational jurisdictions. Local currency rates for the Lesotho loti (LSL) (pegged to the South African rand) and Botswana pula (BWP) were weaker against the US dollar during the year (compared to 2019), which reduced the Group's US dollar-reported costs.

1 Non-cash accounting charges include waste stripping cost amortised, inventory and ore stockpile adjustments, and the impact of adopting IFRS 16 Leases, and exclude depreciation and mining asset amortisation.

2 Direct mine cash costs represent all operating costs, excluding royalty and selling costs.

Royalties and marketing costs

Royalties are paid to the Government of the Kingdom of Lesotho on the value of rough diamonds sold by Letšeng in terms of the operation's mining lease. The Group's sales and marketing operation in Belgium incurs costs relating to diamond selling and marketing. During the year, royalties and selling costs increased by 17% to US$19.8 million (2019: US$16.9 million) in line with the increase in revenue and the increase in royalties from October 2019 from 8% to 10%.

Rough diamond extractions and partnership sales

Letšeng entered into partnership arrangements during the year for the sale of four rough diamonds totalling 240 carats. The partnership arrangements allow for Letšeng to share in the margin uplift on the sale of the resultant polished diamonds, which added revenue to the Group of US$0.6 million in 2020.

Corporate expenses

Central costs are incurred by the Group to provide expertise in all areas of the business model to realise maximum value from the Group's assets. These costs are incurred at the technical and administrative offices in South Africa (in South African rand) and head office in the UK (in British pounds).

Baseline corporate costs for the year were US$7.9 million, a 4% increase compared to 2019 of US$7.7 million. The benefits from the corporate cost initiatives implemented through BT continue to be realised. During the year, US$0.1 million in costs were incurred relating to BT and ad hoc projects (2019: US$1.7 million), resulting in an overall saving of US$1.4 million compared to 2019. The saving is largely due to the suspension of all ad hoc projects during the COVID-19 pandemic.

Underlying EBITDA(1) and attributable profit

Group underlying EBITDA(1) from continuing operations increased by 30% to US$53.2 million (2019: US$41.0 million) as a result of the increase in revenue and the reduction in costs through cash preservation initiatives. Profit attributable to shareholders was US$13.6 million, which translates to 9.8 US cents per share based on a weighted average number of shares in issue of 139.3 million.

Capital expenditure

The Group's focus on cash preservation during COVID-19 resulted in limited capital spend and the deferral of a number of capital projects. Letšeng's capital spend was incurred mainly on continued core drilling; micro diamond analysis and mineral resource studies to firm up the existing mineral resource base (US$0.7 million) (2019: US$0.5 million); and the studies and engineering designs for the construction of the replacement Primary Crusher Area of US$0.3 million (2019: US$0.7 million). In addition, US$0.1 million was spent on COVID-19 screening equipment and hardware.

Total capital expenditure (excluding waste stripping) decreased to US$1.6 million during the year (2019: US$9.7 million).

Cash at hand

The Group generated cash from operating activities (before capital and waste investment of US$48.7 million) of US$96.2 million. The Group ended the year with cash on hand of US$49.8 million (2019: US$11.4 million), of which US$36.2 million is attributable to Gem Diamonds. All scheduled debt repayments during the year were made, totalling US$13.5 million. The overall result is a net increase in cash of US$44.8 million year on year.

Letšeng declared a dividend of LSL400.0 million (US$27.0 million) in 2020 of which LSL250.0 million (US$16.8 million) was paid during 2020, with a further LSL150.0 million (US$10.2 million) payable in March 2021.

Loans and borrowings

At year end, the Group had utilised facilities of US$15.2 million, resulting in a net cash position of US$34.6 million and available facilities of US$60.8 million, comprising a net debt position of US$5.7 million (after US$10.0 million drawdown) at Gem Diamonds and a net cash position of US$40.3 million at Letšeng.

The Group optimised the capital structure to ensure Letšeng's debts were fully repaid at the end of the year, even under COVID-19 circumstances, to ensure lower overall gearing in the medium term should the pandemic have extended implications. The Group has renegotiated the Gem Diamonds' three-year revolving credit facility that expired in December 2020 for a further 12 months up to 31 December 2021. The Group engages regularly with lenders and credit providers to ensure continued access to funding and to manage the Group's cash flow requirements during these current turbulent times.

Repayment of the remaining US$10.0 million balance on the Gem Diamonds Limited facility, relating to the Ghaghoo US$25.0 million debt, was repaid in quarterly instalments during the year, with the final repayment made in December 2020. During 2020, Gem Diamonds accessed US$14.0 million of its three-year RCF. A capital repayment of US$6.0 million was made on the RCF facility in December 2020, ending the year with a US$10.0 million outstanding balance.

Letšeng made repayments of LSL57.3 million (US$3.5 million) on its project debt facility for the construction of the mining workshop complex. The outstanding balance of LSL76.3 million (US$5.2 million) will be repaid by September 2022.

Funding discussions for the replacement PCA continues while the appropriate timing for the commencement of the project is being considered.

The Group has commenced a consolidated debt refinancing of its key credit facilities and has appointed Nedbank Corporate and Investment Banking as the sole mandated lead arranger to drive this process on its behalf.

Discontinued operation

In line with the strategic objective to dispose of non-core assets, the Board and management remain committed to the sale of Ghaghoo. The binding agreement that Gem Diamonds entered into in June 2019 for the sale of 100% of the share capital of Gem Diamonds Botswana Proprietary Limited lapsed due to certain suspensive conditions not being met, however the process was again opened to other prospective buyers during the year and has entered into an exclusivity agreement with an interested party with whom potential sale discussins are continuing.

The sales process faced considerable delays in 2020 largely due to the impact of COVID-19 and in particular the related travel restrictions that prohibited site visits for due diligence purposes. The process is expected to be concluded in 2021.

The operation remains on care and maintenance and is classified as a discontinued operation in accordance with IFRS 5 Non-current Assets Held for Sale and Discontinued Operations. Care and maintenance costs were significantly reduced to US$3.3 million (2019: US$4.5 million) and have been recognised and disclosed separately in the Consolidated Statement of Profit or Loss. The reduction in costs was mainly due to the renegotiation of key contracts following the suspension of the de-watering programme. The suspension realised savings relating to reduced fuel consumption on site and ancillary costs associated with de-watering. Further cost reductions were driven by insurance premium decreases, termination of a transport contract, reducing the workforce in line with reduced care and maintenance operations and renegotiation of a generator rental contract.

Share-based payment

The share-based payment charge for the year was US$0.6 million (2019: US$0.8 million). On 9 June, 1 249 000 nil-cost options were granted to certain key employees and Executive Directors under the long-term incentive plan of the Group with similar conditions as previous awards granted under this scheme.

DIVID

As a result of the Group's disciplined capital and cash management, and its strong cash generation during the year in a challenging environment, the Board is pleased to recommend the payment of an ordinary cash dividend of 2.5 US cents in respect of the 2020 financial year. The dividend is subject to shareholder approval at the scheduled AGM to be held on 2 June 2021.

TAXATION

The Group has applied all relevant principles in accordance with prevailing legislation in assessing its tax obligations.

The Group's effective tax rate was 28%. Most of the Group's taxes are incurred in Lesotho, which has a corporate tax rate of 25%. The effective tax rate is above the Lesotho corporate tax rate as a result of deferred tax assets not recognised on losses incurred in operations during the year, partially offset by a reduction in the deferred tax liability on unremitted earnings. Governments in various countries introduced certain tax payment deferment measures to reduce the impact of COVID-19 on companies during the lockdown period, and where applicable all taxes were paid before year-end, in line with the deferrals offered.

During the year the Group received a net tax refund of US$5.9 million in taxes. The US$7.6 million of overpaid taxes relating to the 2019 tax year at Letšeng was refunded during the year. Following the solid financial results at Letšeng, a further tax obligation of US$11.3 million relating to the 2020 tax year is due for payment by March 2021.

As disclosed in the 2019 Annual Report and Accounts, an amended tax assessment was issued to Letšeng by the Lesotho Revenue Authority (LRA) in December 2019, contradicting the application of certain tax treatments in the current Income Tax Act. An objection was lodged by Letšeng in March, which was supported by the opinion of senior counsel, together with an application for the suspension of any payment deemed due. The application for suspension of payment was accepted. The LRA has subsequently lodged an application to the Lesotho High Court pertaining to this matter, which Letšeng is opposing and a court date has been set for 3 August 2021. There has therefore been no change in the judgement applied and the accounting treatment for this matter (refer Note 1.2.28, Critical accounting estimates and judgment for further detail.)

SENSITIVITIES

The Group is exposed to a range of external factors that are outside of its control in the conduct of its business. The Group has the necessary resilience, balance sheet strength and access to funds to adjust for shifts in these factors.

While the full impact of COVID-19 on the diamond industry and the Group's operations is still unfolding, the Group expects that in the medium to long term, rough diamond prices will be supported by favourable demand and supply fundamentals. These include continued growth in demand from markets such as China and India, supported by a projected fall-off in rough diamond supply. This dynamic is expected to benefit high-quality diamonds in particular, where shortages of certain categories of these rough diamonds were already evident during the year.

The Group's business priorities were quickly adapted to the new reality created by COVID-19 and numerous operational projects were deferred to focus on normalising the business. The Group continues to monitor developments and considers the potential primary risks to be disruptions in production resulting in lower throughput and the risk of reduced revenue due to downward pressure on diamond prices and/or decreased demand.

The Group's focus remains on areas of optimisation and cash preservation through re-evaluation of all operational and financial management initiatives, while keeping employees and surrounding communities safe. Effective capital allocation and cost reductions aim to ensure the financial and funding resilience needed to operate in extremely challenging times and to achieve the Group's strategic objectives.

PERFORMANCE

Line managers at Letšeng report to the COO on a weekly basis. This was increased to daily meetings at Letšeng and weekly meetings at Ghaghoo following the onset of the pandemic and the resultant operational impacts.

Weekly meetings were held with contractors, line management and the COO to ensure alignment and understand challenges in addressing COVID-19 impacts.

Over and above quarterly reports to the Board, the COO and CFO meet with a non-Executive Director about operational governance on a weekly basis.

Weekly cash flow meetings with Letšeng are held and line managers submit a monthly operational report to both the COO and CFO, which provides performance feedback on metrics involving:

   --      health and safety; 
   --      COVID-19 testing and management; 
   --      production and operational performance; 
   --      TSF management and monitoring; and 
   --      current projects' progress discussions. 

Safety

Letšeng's approach to safety is built on the culture of behaviour-based care at work and a commitment to zero harm. The Group's intensified focus on safety and the benefits of visible leadership and training is evident in the positive operational safety trends seen in 2020. One LTI was recorded at Letšeng during 2020 (2019: seven); and the LTIFR decreased to 0.04 (2019: 0.28). The Group reported the lowest AIFR in a decade after the AIFR improved to 0.76 (2019: 0.97). Although the focus on the Safety Turnaround Strategy implemented in 2020 saw a decrease in LTIs during 2020, management has also implemented pro-active actions to prevent the recurrence of certain near-miss incidents that could potentially have severe outcomes. Letšeng is putting into effect a strategy to reduce LTIs, and to ensure behaviour-based care is integrated at the operation to continue to reduce all safety incidents. There were no LTIs during 2020 at Ghaghoo or anywhere else in the Group.

1 Includes carats produced from the Letšeng plants, the Alluvial Ventures (AV) plant and the tailings treatment plant.

Letšeng suspended operations and placed the mine on care and maintenance from 28 March to 26 April in compliance with the Government of Lesotho's lockdown order. Mining and ore treatment restarted in a phased approach in April and ramp-up to full production at both treatment plants was achieved in May, with waste mining recommencing in July, in accordance with a revised 2020 mine plan.

Waste tonnes mined decreased 35% to 15.6 million tonnes from 24.0 million tonnes in 2019, impacted by the shutdown of operations in Q2, the focus on cash preservation and based on a revised 2020 mining plan. Availability of primary waste diggers and waste hauling trucks was lower than call due to reduced availability of critical spares and maintenance services, largely as a result of the imposed COVID-19-related lockdowns and travel restrictions.

Ore tonnes treated during 2020 of 5.4 million tonnes comprised 4.5 million tonnes treated by Letšeng's plants (2019: 5.6 million) and 0.9 million tonnes treated by the third-party processing contractor Alluvial Ventures (AV) (2019: 1.1 million). Of the total ore treated, 2.6 million was sourced from the Main pipe, 2.8 million from the Satellite pipe with only a negligible number of tonnes from the Main pipe stockpiles. Ore tonnes treated was impacted by the shutdown and phased ramp-up, the planned reduction in processing feed rates to improve plant stability with the aim of increasing diamond recoveries, electricity supply interruptions, and and an increase in planned maintenance to ensure equiment reliability. Due mainly to the lost processing time during the shutdown period and phased ramp-up in Q2, a higher proportion of Satellite pipe ore was treated in 2020 to maximise revenue and cash generation, particularly in the second half of the year. The coarser and harder Satellite pipe material, however, negatively impacts throughput capacity in the plants.

Total carats recovered in 2020 decreased 12% to 100 780 (2019: 113 974), largely as a result of no tonnes being treated during the 30-day shutdown period and reduced tonnes during the ramp-up phase.

The BT initiative to re-treat historic and current recovery tailings through the mobile XRT sorting machine yielded 1 341 carats in 2020 (2019: 5 420 carats). The decrease compared to 2019 is largely due to improved recoveries within the coarse recovery system and the depletion of historic coarse recovery tailings material.

Overall grade for 2020 was 1.85cpht, an increase of 9% on the 1.70cpht realised in 2019 due to the higher contribution of Satellite pipe ore in 2020, which has a higher grade relative to Main pipe ore. The grade for the ore processed during the year was in line with its expected reserve grade.

Large diamond recoveries

In 2020 Letšeng recovered 16 diamonds greater than 100 carats each (2019:11); and total diamonds recovered greater than 10 carats increased by 5% year on year.

Mineral resources and reserves

While studies related to the updating of Letšeng's Resource and Reserve Statement continued throughout 2020, there were considerable delays due to the lockdowns in Lesotho, South Africa and Canada. Analysis and interpretation of results progressed, including comprehensive petrography, mineral chemistry (Mantle Mapper and chromite microprobe test work) and microdiamond analysis of drill core and grab samples, all of which complement the core logging data and guide the 3D geological modelling process.

Bulk sampling of the various volumetrically significant subdomains is ongoing within the mining and treatment production schedules. The low grades of all kimberlites at Letšeng mean that substantial bulk samples are required to collect sufficient diamond data to confidently estimate grade and diamond value.

The timeline for updating the Resource and Reserve Statement was further impacted by the relatively internal geology recognised during the detailed petrographic studies on historical and new core obtained during the 2017-2018 drilling programme. As a result, additional core drilling is required to confirm the classification of certain portions of the Resource as Indicated.

The necessary additional core drilling commenced with a new drill rig purchased in November 2020. This drilling programme was designed to increase drillhole density in certain areas and confirm internal contacts. Logging and sampling of the core will be carried out at Letšeng in parallel with external petrographic analysis to complete the work required for the Resource and Reserve Statement and the supporting technical report.

Diamond sales

Travel and other COVID-19-related restrictions implemented in many countries worldwide, and particularly in Belgium, Israel and India, impacted on the Group's sales process. Flexible tender processes were successfully introduced in strict compliance with COVID-19 health and safety protocols, including appropriate social distancing guidelines and sanitation measures. This allowed for sales to be conducted by limited tender and/or allowing clients to view diamonds virtually before tendering. Additional rough diamond analysis information of selected large high-value diamonds was provided to assist clients who could not physically attend the tenders to virtually view the diamonds prior to bidding on the tender platform.

Six rough diamond tender viewings were held in Antwerp and one in Tel Aviv during the year. A total of 99 172 carats were sold by Gem Diamonds Marketing Services (2019: 111 292). Letšeng generated rough diamond revenue of US$189.2 million (2019: US$182.0 million), at an average price of US$1 908 per carat (2019: US$1 637).

Capital projects

Capital requirements for 2020 were reviewed as a result of COVID-19 with savings realised and a portion of planned capital expenditure deferred to future years. During the year, the limited capital spend related to the progress of the resource and reserve statement, the expansion of the Patiseng Tailings Storage Facility and the initial design work to replace the ageing primary crushing area (PCA). Details of overall costs and capital expenditure incurred at Letšeng during the period are included in CFO report on pages 36 to 42.

Business Transformation (BT) and Continuous Improvement (CI)

The Group's Business Transformation (BT) programme started in 2018, with the goal of delivering US$100 million in revenue, productivity and cost savings (against the 2017 base) by the end of 2021. 325 initiatives were identified to create a step change in efficiency, productivity and cost management, and to position Gem Diamonds favourably in its peer group. The BT programme included four primary workstreams - mining, processing, working capital and overheads, and corporate activities.

The target included US$7.1 million in once-off savings and US$92.9 million in cumulative recurring annualised benefits over the four-year period. This target is stated net of implementation costs, consultant fees and an employee incentive plan that rewarded the successful delivery of initiatives contributing to the overall target.

The successful implementation of the underlying initiatives over the past three years created a solid operational, financial and cultural platform for the Group to navigate the challenging operating environment over the past few years and more recently to absorb the external shock of the COVID-19 pandemic. The process underpinning the material initiatives that contribute to the US$100 million target are embedded and sustainable and, notwithstanding the 30-day shutdown and reduced operations in Q2 2020 which negatively impacted certain of the initiatives, the full delivery of the target by end 2021 remains on track. By the end of the year, the BT programme delivered US$79.2 million of the target.

Many of the BT processes focused on improved efficiencies in the use of our natural resources, which also mitigate the operational impact on the natural environment. This supports the Group's strategy of maximising benefit for our communities and minimising our impact on the environment.

The transition from BT to CI at Letšeng is progressing well. CI focuses on behavioural strategies and the implementation of meaningful key performance indicators for effective visual management and problem solving (using the 5-WHY methodology) at all levels. CI, supported by software training, enables the Group to continuously improve efficiencies by unlocking the inherent capabilities of employees at all levels to implement CI best practices, build effective teams, drive incremental improvements and create a high-performance culture. The successful implementation of CI in the Mining area at Letšeng has resulted in marked operational efficiencies, such as improved adherence to drilling parameters and blasting quality during 2020. Roll-out to the Treatment and Services areas has commenced. Taskforce members in Treatment have been identified and they have undergone the introductory training.

Dam safety and integrity

Tailings dam integrity is an ongoing area of focus for mining companies and investors, in recognition of the possible adverse impact that a failure at one of these facilities may have on human lives and the natural environment. Letšeng has three dams on site - (i) the Patiseng tailings storage facility (TSF), which is currently in use for the deposition of coarse and fine slimes tailings, (ii) the old TSF, which is a semi-dormant facility currently used only for emergency deposition of fines tailings, and (iii) the Mothusi Dam, which is the mine's freshwater supply resource. These dams were constructed using the 'centre line and downstream tipping' method(1) . Most recent dam failures reported in the mining industry were related to dams built using 'upstream' construction methods.

The relevant details of these facilities are available in Gem Diamonds' voluntary disclosure as part of the Investor Mining & Tailings Safety initiative set up by the Church of England, which can be found under the Company's name at http://tailing.grida.no/ . Read more about progress in 2020 on page 50.

Reducing diamond damage

The unique diamond distribution in Letšeng's orebody comprises a high proportion of larger high-value Type II diamonds that are more susceptible to damage in mining and processing. Reducing diamond damage therefore provides an important opportunity for Gem Diamonds to significantly enhance revenue.

Opportunities to reduce diamond damage that show the most potential include:

   --      early identification of diamonds within kimberlite; and 
   --      non-mechanical means of liberating these diamonds within kimberlite. 

Over the last five years, Gem Diamonds has made significant progress in identifying, validating and testing technologies from various industries that show potential for early detection and non-mechanical liberation of diamonds.

Following the successful proof of concept, the Group's wholly owned subsidiary, Gem Diamonds Innovation Solutions, constructed and commissioned a pilot plant at Letšeng in 2019 to test the technology under operating conditions. The pilot plant combines scanning technology that uses proprietary imaging and sorting algorithms to detect diamonds within kimberlite with high-voltage pulse power for non-mechanical fragmentation of composite materials to liberate the encapsulated diamonds.

A steering committee is in place to oversee the project, chaired by the CEO. Advancing of the pilot during the year was negatively impacted by COVID-19, the revised capital expenditure plan, inconstant electricity and water supply, and challenges with the reliability of certain key components. The work done to date demonstrates the potential of the technology to reduce diamond damage and the Group remains committed to the project. New partners were identified to advance the pilot processing plant to detect diamonds within kimberlite and further enhancement and testing will continue in 2021.

Providing clarity for customers

Increasing consumer interest in social and environmental factors when making buying decisions, particularly among younger consumers, provides an opportunity for ethical and responsible producers like Gem Diamonds. Blockchain technology is a way to securely link the source of rough diamonds with the final polished diamonds, proving their authenticity, provenance and traceability, and supporting ethical sourcing and processing in the diamond value chain. Solutions currently available offer consumers information about the country of origin of their diamonds, as well as the positive impact the mine and the broader industry have on the communities and countries in which they operate. We have been participating in the GIA's Diamond Origin programme since the start of 2020 and have been sending large, high-value diamonds for rough analysis as time and lockdown regulations allow.

FUTURE FOCUS AREAS 2021

Our focus to further reduce waste stripping will continue. An analysis was completed in 2020 to further steepen pit slope angles. A trial to further steepen the west side of the Satellite pipe is scheduled to commence in H1 2021.

Following the completion of the design work of the replacement PCA, the application for funding continues while the appropriate timing for the commencement of the project is being considered.

      availability of goods and lockdown                         prices, exchange rates, inflation rates, by comparing

      There is an inherent uncertainty in

      flows, which forms                                         assumptions used in the impairment and going concern 
      the basis of the Group's value in use                      models. We did this by increasing and decreasing the 
      calculations used in the impairment                        following assumptions in the model to determine the 
      model and the going                                        impact on the headroom between the value of the

      of the Covid-19                                            concern. These included: 
      pandemic including uncertainty around 
      the duration of the pandemic and timing 
      of the recovery                                      o Exchange rates

                                                            *    We evaluated the progress on the renewal of the 
      As disclosed in Note 12 Impairment                         borrowing facilities through inquiry and inspection 
      testing and Note 1.2.2 Going Concern,                      of communications with lenders;

      going concern, on the basis of the                         statements. 
      following key assumptions: 
       *    Diamond prices; 
 
 
       *    Inflation rates; 
 
 
       *    Production costs and volumes;

       *    Discount rates; and 
 
 
       *    Exchange rates 
 
 
 
      Given the above factors, the goodwill 
      impairment and the assessment of cash 
      flows in the going 
      concern model, particularly in the 
      diamond mining industry, required 
      significant audit attention 
      in the current year through extended 
      sensitivity and stress testings with 
      different scenarios 
      including the use of our valuation 
      experts.

Other information

Management is responsible for the other information. The other information comprises the information included in the 185-page document titled "Gem Diamonds Limited Annual report and accounts 2020". The other information does not include the consolidated financial statements and our auditor's reports thereon.

Our opinion on the consolidated financial statements does not cover the other information and we do not express any form of assurance conclusion thereon.

In connection with our audit of the consolidated financial statements, our responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent with the consolidated financial statements or our knowledge obtained in the audit or otherwise appears to be materially misstated. If, based on the work we have performed, we conclude that there is a material misstatement of this other information, we are required to report that fact. We have nothing to report in this regard.

Responsibilities of management and those charged with governance, for the Consolidated Financial Statements

Management is responsible for the preparation and fair presentation of the consolidated financial statements in accordance with IFRSs, and for such internal control as management determines is necessary to enable the preparation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the consolidated financial statements, management is responsible for assessing the Group's ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless management either intends to liquidate the Group or to cease operations, or has no realistic alternative but to do so.

Auditor's responsibilities for the audit of the Consolidated Financial Statements

Our objectives are to obtain reasonable assurance about whether the consolidated financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor's report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with ISAs will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these consolidated financial statements.

As part of an audit in accordance with ISAs, we exercise professional judgment and maintain professional skepticism throughout the audit. We also:

-- Identify and assess the risks of material misstatement of the consolidated financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control.

-- Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Group's internal control.

-- Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by management.

-- Conclude on the appropriateness of management's use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Group's ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our auditor's report to the related disclosures in the consolidated financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditor's report. However, future events or conditions may cause the Group to cease to continue as a going concern.

-- Evaluate the overall presentation, structure and content of the consolidated financial statements, including the disclosures, and whether the consolidated financial statements represent the underlying transactions and events in a manner that achieves fair presentation.

-- Obtain sufficient appropriate audit evidence regarding the financial information of the entities or business activities within the group to express an opinion on the consolidated financial statements. We are responsible for the direction, supervision and performance of the group audit. We remain solely responsible for our audit opinion.

We communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that we identity during our audit.

We also provide those charged with governance with a statement that we have complied with relevant ethical requirements regarding independence, and to communicate with them all relationships and other matters that may reasonably be thought to bear on our independence, and where applicable, actions taken to eliminate threats or safeguards applied.

From the matters communicated with those charged with governance, we determine those matters that were of most significance in the audit of the consolidated financial statements of the current period and are therefore the key audit matters. We describe these matters in our auditor's report unless law or regulation precludes public disclosure about the matter or when, in extremely rare circumstances, we determine that a matter should not be communicated in our report because the adverse consequences of doing so would reasonably be expected to outweigh the public interest benefits of such communication.

          1 The cost of investment represents original cost of investments at acquisition dates. 
           2 No change in the shareholding since the prior year. 
           3 During the year Gem Equity Group (GEG) sold its investments, 2% in Gem Diamonds Marketing 
           Services BVBA and 1% in Baobab Technologies investments, to Gem Diamonds Investments Limited. 
           Following the sale of GEG's investments the GEG Board of Directors resolved to voluntarily 
           liquidate GEG. As the operation is being closed and not sold the closure has been classified 
           as an abandonment by the Company. 
           4 The Ghaghoo Diamond Mine, which is in the process of being sold, has been classified as 
           a discontinued operation held for sale since 30 June 2019 and disclosed separately (refer 
           Note 16, Asset held for sale). 
 1.1.3         Segment information 
                For management purposes, the Group is organised into geographical units as its risks and required 
                rates of return are affected predominantly by differences in the geographical regions of the 
                mines and areas in which the Group operates or areas in which operations are managed. The 
                below measures of profit or loss, assets and liabilities are reviewed by the Chief Operating 
                Decision-Maker, ie Board of Directors. The main geographical regions and the type of products 
                and services from which each reporting segment derives its revenue from are: 
                 *    Lesotho (diamond mining activities); 
 
 
                 *    Belgium (sales, marketing and manufacturing of 
                      diamonds); 
 
 
                 *    BVI, RSA, UK and Cyprus (technical and administrative 
                      services); and 
 
 
                 *    Botswana (diamond mining activities), classified as 
                      discontinued operation held for sale since 30 June 
                      2019. 
 
 
 
                Management monitors the operating results of the geographical units separately for the purpose 
                of making decisions about resource allocation and performance assessment. 
 
                Gem Diamonds Botswana (Ghaghoo Diamond Mine), which during the prior year was classified as 
                a discontinued operation held for sale and separately disclosed, continues to be classified 
                as such as management remain committed to the sales process. Refer Note 16, Asset held for 
                sale. 
 
                During the year GEG, a dormant investment company, was abandoned. Following the sale of its 
                investments the Board of Directors of GEG resolved to voluntarily liquidate the operation, 
                which remains an ongoing process and is expected to be concluded subsequent to year end 31 
                December 2020. GEG is classified as part of the BVI, RSA, UK and Cyprus segment. 
 
                Segment performance is evaluated based on operating profit or loss. Intersegment transactions 
                are entered into under normal arm's length terms in a manner similar to transactions with 
                third parties. Segment revenue, segment expenses and segment results include transactions 
                between segments. Those transactions are eliminated on consolidation. 
 
                Segment revenue is derived from mining activities, polished manufacturing margins, and Group 
                services.

            1 No revenue was generated in BVI and Cyprus. 
            2 Calculated as cash and short-term deposits less drawndown bank facilities (excluding the 
            asset-based finance facility, insurance premium financing and rolling fees capitalised to 
            the Company's US$30.0 million bank loan facility. Refer Note 18, Interest-bearing loans and 
            borrowings). 
            3 Non-cash movements in rehabilitation assets relating to changes in rehabilitation estimates 
            for the Lesotho segment. 
          Included in revenue for the current year is revenue from six customers which amounted to US$66.9 
           million arising from sales reported in the Belgium segments. 
 
           Segment assets and liabilities do not include deferred tax assets and liabilities of US$6.3 
           million and US$84.5 million respectively. 
 
           Total revenue for the year is higher than that of the prior year mainly due to higher sales 
           prices achieved of US$1 908 (2019: US$1 637). 
 
           During the year, COVID-19 had the following impact on revenue: 
            *    Production volumes were negatively impacted as a

 1.2      Summary of significant accounting policies 
 1.2.1    Basis of preparation 
           The financial statements of the Group have been prepared in accordance with International 
           Financial Reporting Standards (IFRS), as issued by the International Accounting Standards 
           Board (IASB). These financial statements have been prepared under the historical cost basis 
           except for assets and liabilities measured at fair value. The accounting policies have been 
           consistently applied except for the adoption of the new standards and interpretations detailed 
           on the following pages. 
 
           The functional currency of the Company and certain of its subsidiaries is US dollar, which 
           is the currency of the primary economic environment in which the entities operate. All amounts 
           are presented in US dollar and rounded to the nearest thousand. The financial results of subsidiaries 
           whose functional and reporting currency is in currencies other than US dollar have been converted 
           into US dollar on the basis as set out in Note 1.2.16, Foreign currency translations. 
 
           The preparation of financial statements in conformity with IFRS requires the use of certain 
           critical accounting estimates. It also requires management to exercise its judgement in the 
           process of applying the Group's accounting policies. The areas involving a higher degree of 
           judgement or complexity, or areas where assumptions and estimates are significant to the financial 
           statements, are disclosed in Note 1.2.28, Critical accounting estimates and judgements. 
 
           Changes in accounting policies and disclosures 
           New and amended standards and interpretations 
           The Group adopted certain standards and amendments for the first time, which are effective 
           for annual periods beginning on or after 1 January 2020 and are listed in the table. The adoption 
           of these new accounting pronouncements has not had a significant impact on the consolidated 
           financial statements of the Group nor on the accounting policies, methods of computation or 
           presentation applied by the Group.

          Amendment to IFRS 16 - COVID-19 Related Rent Concessions 
           The amendment to IFRS 16, COVID-19 Related Rent Concessions, which is effective for annual 
           financial reporting periods beginning on or after 1 June 2020 has been early adopted by the 
           Group during the current financial reporting period. 
 
           The amendment in the form of a practical expedient, provides optional relief to lessees on 
           the treatment of rent concessions occurring as a direct consequence of the COVID-19 pandemic. 
 
           The expedient allows lessees to account for such rent concessions as if they were not lease 
           modifications if all of the following conditions are met: 
 
           (a) the change in lease payments results in revised consideration for the lease that is substantially 
           the same as, or less than, the consideration for the lease immediately preceding the change; 
           (b) any reduction in lease payments affects only payments originally due on or before 30 June 
           2021; and 
           (c) there is no substantive change to other terms and conditions of the lease. 
 
           The practical expedient was applied to all leases where there was a change in lease payments 
           granted by lessors as a direct consequence of COVID-19 related rental concessions. For leases 
           where concessions have been given in the form of forgiveness, the Group included the forgiveness 
           as negative variable lease payments in the Consolidated Statement of Profit or Loss. For leases 
           where concessions have been given in the form of payment deferrals, the Group continued to 
           account for the lease liability and right-of-use asset using the rights and obligations of 
           the existing lease, with a separate lease payable being recognised for the payment deferred 
           in the period when the allocated lease cash payment is due. This adoption did not have a material 
           impact on the Group. Refer Note 10, Right-of-use assets and Note 19, Lease liabilities. 
 
           New standards issued but not yet effective 
           The new standards, amendments and improvements that are issued, but not yet effective, up 
           to the date of issuance of the Group's consolidated financial statements are listed in the 
           table below. These standards, amendments and improvements have not been early adopted and 
           it is expected that, where applicable, these standards, amendments and improvements will be 
           adopted on each respective effective date. The impact of the adoption of these standards cannot 
           be reasonably assessed at this stage.

          Interest Rate Benchmark Reform - Phase 2 
           The amendment addresses issues that might affect financial reporting when an existing interest 
           rate benchmark is replaced with an alternative benchmark interest rate. 
 
           The Group and its funders have commenced a comprehensive debt refinancing programme of the 
           Group's facilities. The refinancing programme incorporates the consideration of any risk posed 
           to the Group by phase two of the IBOR reform, which is effective from 1 January 2021. The 
           IBOR reform may potentially have an impact on the JIBAR and LIBOR linked interest-bearing 
           loans and borrowings, which includes the LSL215.0 million unsecured project debt facility 
           between Letšeng Diamonds and Nedbank Limited and the Export Credit Insurance Corporation 
           (ECIC) and the US$30.0 million revolving credit facility between Gem Diamonds Limited and 
           Nedbank Capital. Refer Note 18, Interest-bearing loans and borrowings for more information 
           regarding the maturities and the related benchmark rates subject to the IBOR reform on these 
           loans. The Group will continue to assess the impact of these amendments on the Group's Consolidated 
           Annual Financial Statements until initial application. 
 
           Business environment and country risk 
           The Group's operations are subject to country risk being the economic, political and social 
           risks inherent in doing business in certain areas of Africa and Europe. These risks include 
           matters arising out of the policies of the government, economic conditions, imposition of 
           or changes to taxes and regulations, foreign exchange rate fluctuations and the enforceability 
           of contract rights. 
 
           The consolidated financial information reflects management's assessment of the impact of these 
           business environments and country risks on the operations and the financial position of the 
           Group. The future business environment may differ from management's assessment. 
 1.2.2    Going concern 
           The Company's business activities, together with the factors likely to affect its future development, 
           performance and position have been assessed by management. The financial position of the Company, 
           its cash flows and liquidity position are presented in the Annual Report and Accounts. In 
           addition, Note 27, Financial risk management, includes the Company's objectives, policies 
           and processes for managing its capital; its financial risk management objectives; details 
           of its financial instruments; and its exposures to market risk, credit risk and liquidity 
           risk. 
 
           The Group's net cash at 31 December 2020 was US$34.6 million (31 December 2019: net debt US$10.2 
           million) and with its undrawn facilities of US$60.8 million, its liquidity (defined as net 
           cash and undrawn facilities) of US$95.4 million remains strong. However, the Group's Revolving 
           Credit facilities, which total US$70.8 million when fully unutilised, mature within the next 
           12 months, with US$34.0 million maturing in July 2021, US$30.0 million expiring on 31 December 
           2021 and the balance of US$6.8 million being a general banking facility with no set expiry 
           date (Refer Note 18, Interest-bearing loans and borrowings). Management have commenced discussions 
           with lenders to restructure and extend the maturity dates of these facilities and are confident 
           that the facilities will be restructured as per previous successful renewals. The uncertainty 
           that exists around the ongoing impact of COVID-19 on future cashflows was considered by performing 
           sensitivities on diamond pricing and diamond production volumes and continued strengthening 
           of the US$ against the Lesotho Loti. 
 
           After making enquiries which include reviews of forecasts and budgets, timing of cash flows, 
           borrowing facilities and sensitivity analyses and considering the uncertainties described 
           in this report either directly or by cross-reference, the Directors have a reasonable expectation 
           that the Group and the Company have adequate financial resources to continue in operational 
           existence for the foreseeable future. For this reason, they continue to adopt the going concern 
           basis in preparing the Annual Report and Accounts of the Company. 
 
           These financial statements have been prepared on a going concern basis which assumes that 
           the Group will be able to meet its liabilities as they fall due for the foreseeable future. 
 1.2.3    Basis of consolidation 
           The consolidated financial statements incorporate the financial statements of the Company 
           and entities controlled by the Company as at 31 December 2020. 
 
           Subsidiaries 
           Subsidiaries are consolidated from the date of their acquisition, being the date on which 
           the Group obtains control, and continue to be consolidated until the date that such control 
           ceases. An investor controls an investee when it is exposed, or has rights, to variable returns 
           from its involvement with the investee and has the ability to affect those returns through 
           its power over the investee. To meet the definition of control in IFRS 10, all three of the 
           following criteria must be met: (a) an investor has power over an investee; (b) the investor 
           has exposure, or rights, to variable returns from its involvement with the investee; and (c) 
           the investor has the ability to use its power over the investee to affect the amount of the 
           investor's returns. The financial statements of subsidiaries used in the preparation of the 
           consolidated financial statements are prepared for the same reporting year as the parent company 
           and are based on consistent accounting policies. All intragroup balances and transactions, 
           including unrealised gains and losses arising from them, are eliminated in full. 
 
           Non-controlling interests 
           Non-controlling interests represent the equity in a subsidiary not attributable, directly 
           or indirectly, to the parent company and is presented separately within equity in the consolidated 
           statement of financial position, separately from equity attributable to owners of the parent. 
           Losses within a subsidiary are attributed to the non-controlling interest even if that results 
           in a deficit balance. 
 1.2.4    Exploration and evaluation expenditure 
           Exploration and evaluation activity involves the search for mineral resources, the determination 
           of technical feasibility and the assessment of commercial viability of an identified resource. 
           Exploration and evaluation activity includes: 
            *    acquisition of rights to explore; 
 
 
            *    researching and analysing historical exploration 
                 data; 
 
 
            *    gathering exploration data through topographical, 
                 geochemical and geophysical studies; 
 
 
            *    exploratory drilling, trenching and sampling; 
 
 
            *    determining and examining the volume and grade of the 
                 resource; 
 
 
            *    surveying transportation and infrastructure 
                 requirements; and 
 
 
            *    conducting market and finance studies. 
 
 
 
           Administration costs that are not directly attributable to a specific exploration area are 
           charged to the statement of profit or loss. Licence costs paid in connection with a right 
           to explore in an existing exploration area are capitalised, as a component of property, plant 
           and equipment, and amortised over the term of the permit. 
 
           Exploration and evaluation expenditure is capitalised as incurred. Capitalised exploration 
           expenditure is recorded as a component of property, plant and equipment, as an exploration 
           and development asset, at cost less accumulated impairment charges. As the asset is not available 
           for use, it is not depreciated. 
 
           All capitalised exploration and evaluation expenditure is monitored for indications of impairment. 
           Where a potential impairment is indicated, assessments are performed for each area of interest 
           in conjunction with the group of operating assets (representing a cash-generating unit (CGU)) 
           to which the exploration is attributed. To the extent that exploration expenditure is not 
           expected to be recovered, it is charged to the statement of profit or loss. Exploration areas 
           where reserves have been discovered, but require major capital expenditure before production 
           can begin, are continually evaluated to ensure that commercial quantities of reserves exist 
           or to ensure that additional exploration work is under way as planned. 
 
           Management is required to make certain estimates and judgements when determining whether the 
           commercial viability of an identified resource has been met and when determining whether indicators 
           of impairment exist as referred under Note 1.2.28, Critical accounting estimates and judgements. 
 1.2.5    Development expenditure 
           When proved reserves are determined and development is sanctioned, capitalised exploration 
           and evaluation expenditure is reclassified from exploration phase to development phase. As 
           the asset is not available for use, during the development phase, it is not depreciated. On 
           completion of the development phase, any capitalised exploration and evaluation expenditure 
           already capitalised to a development asset, together with the subsequent development expenditure, 
           is reclassified within property, plant and equipment to mining assets and depreciated on the 
           basis as laid out in Note 9, Property, plant and equipment. 
 
           All development expenditure is monitored for indicators of impairment annually. Management 
           is required to make certain estimates and judgements when determining whether indicators of 
           impairment exist as referred under Note 1.2.28, Critical accounting estimates and judgements. 
 1.2.6    Property, plant and equipment 
           Property, plant and equipment are recorded at cost less accumulated depreciation and accumulated 
           impairment losses. Cost includes expenditure that is directly attributable to the acquisition 
           and construction of the items, to get the asset in its condition and location for its intended 
           use among others, professional fees, and for qualifying assets, borrowing costs capitalised 
           in accordance with the Group's accounting policies. 
 
           Subsequent costs to replace a component of an item of property, plant and equipment that is 
           accounted for separately, is capitalised when the cost of the item can be measured reliably, 
           with the carrying amount of the original component being written off. All repairs and maintenance 
           are charged to the statement of profit or loss during the financial period in which they are 
           incurred. 
 
           Depreciation commences when an asset is available for use. Depreciation is charged so as to 
           write off the depreciable amount of the asset to its residual value over its estimated useful 
           life, using a method that reflects the pattern in which the asset's future economic benefits 
           are expected to be consumed by the Group.

            1 Certain asset classes are depreciated over the lesser of life of mine, or period of mining 
            lease. Prior to 1 January 2020, the period of mining lease was shorter than the life of mine. 
            On 1 January 2020 a reassessment of assets' useful lives was performed at Letšeng which 
            resulted in a revision of assets' useful lives being made from a remaining useful life of 
            five years (original period of mining lease) to 15 years (life of mine) due to the extension 
            of the Letšeng mining lease. Furthermore, the useful life of plant and equipment was 
            reassessed from a useful life of 10 years to the remaining life of mine (15 years); and the 
            useful life of vehicles, categorised within the "Other assets category", were reassessed from 
            five years to eight years. 
          An item of property, plant and equipment and any significant part initially recognised is 
           derecognised upon disposal (i.e., at the date the recipient obtains control) or when no future 
           economic benefits are expected from its use or disposal. Any gain or loss arising on derecognition 
           of the asset (calculated as the difference between the net disposal proceeds and the carrying 
           amount of the asset) is included in the statement of profit or loss when the asset is derecognised. 
 
           The asset's residual values, useful lives and methods of depreciation are reviewed annually. 
           Changes in the expected residual values, expected useful life or the expected pattern of consumption 
           of future economic benefits embodied in the asset are considered to modify the depreciation 
           period or method, as appropriate, and are treated as changes in accounting estimates, and 
           adjusted for prospectively, if appropriate. 
 
           Pre-production and in production stripping costs 
           Costs associated with removal of waste overburden are classified as stripping costs. 
 
           Stripping activities that are undertaken during the production phase of a surface mine may 
           create two benefits, being either the production of inventory or improved access to the ore 
           to be mined in the future. Where the benefits are realised in the form of inventory produced 
           in the period, the production stripping costs are accounted for as part of the cost of producing 
           those inventories. Where production stripping costs are incurred and where the benefit is 
           the creation of mining flexibility and improved access to ore to be mined in the future, the 
           costs are recognised as a non-current asset if: 
           (a) future economic benefits (being improved access to the orebody) are probable; 
           (b) the component of the orebody for which access will be improved can be accurately identified; 
           and 
           (c) the costs associated with the improved access can be reliably measured. 
 
           The non-current asset recognised is referred to as a 'stripping activity asset' and is separately 
           disclosed in Note 9, Property, plant and equipment. If all the criteria are not met, the production 
           stripping costs are charged to the statement of profit or loss as operating costs. The stripping 
           activity asset is initially measured at cost, which is the accumulation of costs directly 
           incurred to perform the stripping activity that improves access to the identified component 
           of ore, plus an allocation of directly attributable overhead costs. 
 
           If incidental operations are occurring at the same time as the production stripping activity, 
           but are not necessary for the production stripping activity to continue as planned, these 
           costs are not included in the cost of the stripping activity asset. If the costs of the stripping 
           activity asset and the inventory produced are not separately identifiable, a relevant production 
           measure is used to allocate the production stripping costs between the inventory produced 
           and the stripping activity asset. 
 
           The stripping activity asset is subsequently amortised over the expected useful life of the 
           identified component of the orebody that became more accessible as a result of the stripping 
           activity. Based on proven and probable reserves, the expected average stripping ratio over 
           the average life of the area being mined is used to amortise the stripping activity asset. 
           As a result, the stripping activity asset is carried at cost less amortisation and any impairment 
           losses. The average life of area cost per tonne is calculated as the total expected costs 
           to be incurred to mine the orebody divided by the number of tonnes expected to be mined. The 
           average life of area stripping ratio and the average life of area cost per tonne are recalculated 
           annually in light of additional knowledge and changes in estimates. Changes in the stripping 
           ratio are accounted for prospectively as a change in estimate. 
 
           Management applies judgement to calculate and allocate the production stripping costs to inventory 
           and/or the stripping activity asset(s) as referred under Note 1.2.28, Critical accounting 
           estimates and judgements. 
 1.2.7    Borrowing costs 
           Borrowing costs directly attributable to the acquisition, construction or production of a 
           qualifying asset that necessarily takes a substantial period of time to get ready for its 
           intended use or sale are capitalised as part of the cost of the asset. All other borrowing 
           costs are expensed in the period in which they occur. Borrowing costs consist of interest 
           and other costs that an entity incurs in connection with the borrowing of funds. 
 1.2.8         Non-current assets held for sale and discontinued operations 
                The Group classifies non-current assets and disposal groups as held for sale if their carrying 
                amounts will be recovered principally through a sale transaction rather than through continuing 
                use. Such non-current assets and disposal groups classified as held for sale are measured 
                at the lower of their carrying amount and fair value less costs to sell. Costs to sell are 
                the incremental costs directly attributable to the sale, excluding the finance costs and income 
                tax expense. 
 
                The criteria for held-for-sale classification is regarded as met only when the sale is highly 
                probable, and the asset or disposal group is available for immediate sale in its present condition. 
                Actions required to complete the sale should indicate that it is unlikely that significant 
                changes to the sale will be made or that it will be withdrawn. Management must be committed 
                to the sale expected within one year from the date of the classification. 
 
                Property, plant and equipment and intangible assets are not depreciated or amortised once 
                classified as held for sale. 
 
                Assets and liabilities classified as held for sale are presented separately as current items 
                in the statement of financial position. 
 
                A disposal group qualifies as a discontinued operation if it is a component of an entity that 
                either has been disposed of, or is classified as held for sale, and: 
                a) represents a separate major line of business or geographical area of operations; 
                b) is part of a single co-ordinated plan to dispose of a separate major line of business or 
                geographical area of operations; or 
                c) is a subsidiary acquired exclusively with a view to re-sale. 
 
                Discontinued operations are excluded from the results of continuing operations and are presented 
                as a single amount as profit or loss after tax from discontinued operations in the statement 
                of profit or loss. 
 
                Additional disclosures are provided in Note 16, Assets held for sale. All other notes to the 
                financial statements include amounts for continuing operations, unless indicated otherwise. 
 1.2.9    Goodwill 
           Goodwill is initially measured at cost, being the excess of the aggregate of the acquisition 
           date fair value of the consideration transferred and the amount recognised for the non-controlling 
           interest (and where the business combination is achieved in stages, the acquisition date fair 
           value of the acquirer's previously held equity interest in the acquiree) over the fair value 
           of the net identifiable amounts of the assets acquired and the liabilities assumed in the 
           business combination. 
 
           Assets acquired and liabilities assumed in transactions separate to the business combinations, 
           such as the settlement of pre-existing relationships or post-acquisition remuneration arrangements, 
           are accounted for separately from the business combination in accordance with their nature 
           and applicable IFRS. 
 
           Identifiable intangible assets, meeting either the contractual legal or separability criterion 
           are recognised separately from goodwill. Contingent liabilities representing a present obligation 
           are recognised if the acquisition date fair value can be measured reliably. 
 
           If the aggregate of the acquisition date fair value of the consideration transferred and the 
           amount recognised for the non-controlling interest (and where the business combination is 
           achieved in stages, the acquisition date fair value of the acquirer's previously held equity 
           interest in the acquiree) is lower than the fair value of the net identifiable amounts of 
           the assets acquired and the liabilities assumed in the business combination, the difference 
           is recognised in profit and loss. 
 
           After initial recognition, goodwill is measured at cost less any accumulated impairment losses. 
           For the purpose of impairment testing, goodwill acquired in a business combination is, from 
           the acquisition date, allocated to each of the Group's CGUs (or groups of CGUs) that are expected 
           to benefit from the combination, irrespective of whether other assets or liabilities of the 
           acquiree are assigned to those units. Each unit or group of units to which goodwill is allocated 
           shall represent the lowest level within the entity at which the goodwill is monitored for 
           internal management purposes, and shall not be larger than an operating segment before aggregation. 
 
           Where goodwill forms part of a CGU and part of the operation within that unit is disposed 
           of, the goodwill associated with the operation disposed of is included in the carrying amount 
           of the operation when determining the gain or loss on disposal of the operation. Goodwill 
           disposed of in this circumstance is measured based on the relative values of the operation 
           disposed of and the portion of the CGU retained. 
 1.2.10   Financial instruments 
           The Group shall only recognise a financial instrument when the Group becomes a party to the 
           contractual provisions of the instrument. A financial instrument is any contract that gives 
           rise to a financial asset of one entity and a financial liability or equity instrument of 
           another entity. 
 
           Financial assets 
           Management determines the classification of its financial assets at initial recognition and 
           re-evaluates this designation at every reporting date based on the business model for managing 
           these financial assets and the contractual cash flow characteristics. Currently the Group 
           only has financial assets at amortised cost which consist of receivables and other assets, 
           and cash and short-term deposits which is held within a business model to collect contractual 
           cash flows and for which the contractual cash flow characteristics are solely payments of 
           principal interest. When financial assets are recognised initially, they are measured at fair 
           value plus (in the case of financial assets not at fair value through profit or loss) directly 
           attributable transaction costs. Purchases or sales of financial assets that require delivery 
           of assets within a time frame established by regulation or convention in the market place 
           (regular way trades) are recognised on the trade date. 
 
           Financial assets at amortised cost 
           Financial assets at amortised cost are non-derivative financial assets with fixed or determinable 
           payments that are not quoted in an active market. They are included in current assets, except 
           those with maturities greater than 12 months after the reporting date. These are classified 
           as non-current assets. Such assets are carried at amortised cost using the effective interest 
           rate method, if the time value of money is significant, less any allowance for impairment. 
           Gains and losses are recognised in the statement of profit or loss when the financial assets 
           at amortised cost are derecognised or impaired, as well as through the amortisation process. 
 
           Derecognition 
           A financial asset is primarily derecognised when the rights to receive cash flows from the 
           asset have expired or the Group has transferred its rights to receive cash flows from the 
           asset. Gains or losses from derecognition of financial assets are recognised in the statement 
           of profit or loss. 
 
           Financial liabilities 
           Financial liabilities are subsequently stated at amortised cost using the effective interest 
           rate method, with any difference between proceeds (net of transaction costs) and the redemption 
           value being recognised in the statement of profit or loss, unless capitalised in accordance 
           with Note 1.2.7, Borrowing costs, over the contractual period of the financial liability. 
           Derecognition 
           A financial liability is derecognised when the obligation under the liability is discharged 
           or cancelled or expires. Gains or losses from derecognition of financial liabilities are recognised 
           in the statement of profit or loss. 
 1.2.11   Fair value measurement 
           The Group measures financial instruments at fair value at each reporting date. 
 
           Fair value is the price that would be received to sell an asset or paid to transfer a liability 
           in an orderly transaction between market participants at the measurement date. The fair value 
           measurement is based on the presumption that the transaction to sell the asset or transfer 
           the liability takes place either: 
            *    in the principal market for the asset or liability; 
                 or 
 
 
            *    in the absence of a principal market, in the most 
                 advantageous market for the asset or liability. 
 
 
 
           The principal or the most advantageous market must be accessible by the Group. 
 
           The fair value of an asset or a liability is measured using the assumptions that market participants 
           would use when pricing the asset or liability, assuming that market participants act in their 
           economic best interest. 
 
           A fair value measurement of a non-financial asset takes into account a market participant's 
           ability to generate economic benefits by using the asset in its highest and best use or by 
           selling it to another market participant that would use the asset in its highest and best 
           use. 
 
           The Group uses valuation techniques that are appropriate in the circumstances and for which 
           sufficient data is available to measure fair value, maximising the use of relevant observable 
           inputs and minimising the use of unobservable inputs. All assets and liabilities for which 
           fair value is measured or disclosed in the financial statements are categorised within the 
           fair value hierarchy, described as follows, based on the lowest level input that is significant 
           to the fair value measurement as a whole: 
 
           Level 1: Quoted (unadjusted) market prices in active markets for identical assets or liabilities. 
           Level 2: Valuation techniques for which the lowest level input that is significant to the 
           fair value measurement is directly or indirectly observable. 
           Level 3: Valuation techniques for which the lowest level input that is significant to the 
           fair value measurement is unobservable. 
 
           For assets and liabilities that are recognised in the financial statements that are measured 
           at fair value on a recurring basis, the Group determines whether transfers have occurred between 
           levels in the fair hierarchy by reassessing categorisation (based on the lowest level input 
           that is significant to the fair value measurement as a whole) at the end of each reporting 
           period. 
 1.2.12   Impairments 
           Non-financial assets 
           The Group assesses, at each reporting date, whether there is an indication that an asset (or 
           CGU) may be impaired in accordance with IAS 36. Goodwill is assessed for impairment on an 
           annual basis and when circumstances indicate that the carrying value may be impaired. An impairment 
           loss is recognised for the amount by which the asset's carrying amount exceeds its recoverable 
           amount. The recoverable amount is the higher of an asset's fair value less costs to sell and 
           value in use. In assessing value in use, the estimated future cash flows are discounted to 
           their present value using a pre-tax discount rate that reflects current market assessments 
           of the time value of money and the risks specific to the asset. 
 
           Non-financial assets that were previously impaired are reviewed for possible reversal of the 
           impairment at each reporting date. A previously recognised impairment loss is reversed only 
           if there has been a change in the estimates used to determine the asset's recoverable amount 
           since the last impairment loss was recognised. If that is the case, the carrying amount of 
           the asset is increased to its recoverable amount. That increased amount cannot exceed the 
           carrying amount that would have been determined, net of depreciation, had no impairment loss 
           been recognised for the asset in prior years. Such a reversal is recognised in the statement 
           of profit or loss. After such a reversal the depreciation charge is adjusted in future periods 
           to allocate the asset's revised carrying amount, less any residual value, on a systematic 
           basis over its remaining useful life. Impairment losses relating to goodwill cannot be reversed 
           in future periods. 
 
           Financial assets 
           Assets carried at amortised cost 
           The Group recognises an allowance for expected credit losses (ECLs) for all financial assets 
           at amortised costs in the statement of profit or loss. ECLs are based on the difference between 
           the contractual cash flows due in accordance with the contract and all the cash flows that 
           the Group expects to receive, discounted at an approximation of the original effective interest 
           rate. The expected cash flows will include cash flows from the sale of collateral held or 
           other credit enhancements that are integral to the contractual terms. 
 
           For credit exposures for which there has not been a significant increase in credit risk since 
           initial recognition, ECLs are provided for credit losses that result from default events that 
           are possible within the next 12-months (a 12-month ECL). For those credit exposures for which 
           there has been a significant increase in credit risk since initial recognition, a loss allowance 
           is required for credit losses expected over the remaining life of the exposure, irrespective 
           of the timing of the default (a lifetime ECL). 
 1.2.13   Inventories 
           Inventories, which include rough diamonds, ore stockpiles and consumables, are measured at 
           the lower of cost and net realisable value. The amount of any write-down of inventories to 
           net realisable value and all losses, is recognised in the period the write-down or loss occurs. 
           Cost is determined as the average cost of production, using the weighted average method. Cost 
           includes directly attributable mining overheads, but excludes borrowing costs. 
 
           Net realisable value is the estimated selling price in the ordinary course of business, less 
           the estimated costs of completion and the estimated costs to be incurred in marketing, selling 
           and distribution. 
 1.2.14   Cash and cash equivalents 
           Cash and cash equivalents are carried in the statement of financial position at amortised 
           cost. Cash and cash equivalents comprise cash on hand, deposits held at call with banks, and 
           other short-term, highly liquid investments with original maturities of three months or less. 
 
           For the purpose of the consolidated statement of cash flows, cash and cash equivalents consist 
           of cash and cash equivalents as defined above, net of outstanding bank overdrafts. 
 1.2.15   Issued share capital 
           Ordinary shares are classified as equity. Incremental costs directly attributable to the issue 
           of new shares or options are shown in equity as a deduction from the proceeds. 
 1.2.16   Foreign currency translations 
           Presentation currency 
           The results and financial position of the Group's subsidiaries which have a functional currency 
           different from the Group's presentation currency are translated into the Group's presentation 
           currency as follows: 
            *    statement of financial position items are translated 
                 at the closing rate at the reporting date; 
 
 
            *    income and expenses for each statement of profit or 
                 loss are translated at average exchange rates (unless 
                 this average is not a reasonable approximation of the 
                 cumulative effect of the rates prevailing on the 
                 transaction dates, in which case income and expenses 
                 are translated at the dates of the transactions); and 
 
 
            *    resulting exchange differences are recognised as a 
                 separate component of equity. 
 
 
 
           Details of the rates applied at the respective reporting dates and for the statement of profit 
           or loss transactions are detailed in Note 17, Issued capital and reserves. 
 
           Transactions and balances 
           Foreign currency transactions are translated into the functional currency using the exchange 
           rates prevailing at the dates of the transactions. Foreign exchange gains or losses resulting 
           from the settlement of such transactions and from the translation at the period-end exchange 
           rates of monetary assets and liabilities denominated in foreign currencies are recognised 
           in the statement of profit or loss. Non-monetary items that are measured in terms of cost 
           in a foreign currency are translated using the exchange rates as at the dates of the initial 
           transactions. Non-monetary items measured at fair value in a foreign currency are translated 
           using the exchange rates at the date when the fair value was determined. Monetary items for 
           each statement of financial position presented are translated at the closing rate at the reporting 
           date. 
 1.2.17   Share-based payments 
           Employees (including Senior Executives) of the Group receive remuneration in the form of share-based 
           payment transactions, whereby employees render services as consideration for equity instruments 
           (equity-settled transactions). In situations where some or all of the goods or services received 
           by the entity as consideration for equity instruments cannot be specifically identified, they 
           are measured as the difference between the fair value of the share-based payment and the fair 
           value of any identifiable goods or services received at the grant date. 
 
           Equity-settled transactions 
           The cost of equity-settled transactions with employees are measured by reference to the fair 
           value of the equity instruments at the date at which they are granted and is recognised as 
           an expense over the vesting period, which ends on the date on which the relevant employees 
           become fully entitled to the award. Fair value is determined using an appropriate pricing 
           model. In valuing equity-settled transactions, no account is taken of any vesting conditions, 
           other than conditions linked to the price of the shares of the Company (market conditions). 
 
           No expense is recognised for awards that do not ultimately vest, except for awards where vesting 
           is conditional upon a market condition, which are treated as vesting irrespective of whether 
           or not the market condition is satisfied, provided that all other performance conditions are 
           satisfied. 
 
           At each reporting date before vesting, the cumulative expense is calculated, representing 
           the extent to which the vesting period has expired and management's best estimate of the achievement 
           of the vesting conditions or otherwise of the non-market vesting conditions and of the number 
           of equity instruments that is expected to ultimately vest or, in the case of an instrument 
           subject to a market condition, be treated as vesting as described above. The movement in cumulative 
           expense since the previous reporting date is recognised in the statement of profit or loss, 
           with a corresponding entry in equity. 
 
           Where the terms of an equity-settled award are modified, or a new award is designated as replacing 
           a cancelled or settled award, the cost based on the original award terms continues to be recognised 
           over the original vesting period. In addition, an expense is recognised over the remainder 
           of the new vesting period for the incremental fair value of any modification, based on the 
           difference between the fair value of the original award and the fair value of the modified 
           award, both as measured on the date of the modification. No reduction is recognised if this 
           difference is negative, due to the fact that it would not be beneficial to the employees. 
 
           Where an equity-settled award is cancelled, it is treated as if it had vested on the date 
           of cancellation, and any cost not yet recognised in the statement of profit or loss for the 
           award is expensed immediately. Where an equity-settled award is forfeited, it is treated as 
           if vesting conditions had not been met and all costs previously recognised are reversed and 
           recognised in income immediately within the year of forfeiture. 
 
           Management applies judgement when determining whether share options relating to employees 
           who resigned before the end of the service condition period are cancelled or forfeited as 
           referred under Note 1.2.28, Critical accounting estimates and judgements. 
 
           The Group periodically releases the share-based equity reserve to retained earnings in relation 
           to lapsed, forfeited and exercised options. 
 1.2.18   Provisions 
           Provisions are recognised when: 
            *    the Group has a present legal or constructive 
                 obligation as a result of a past event; and 
 
 
            *    a reliable estimate can be made of the obligation. 
 
 
 
           Provisions are measured at the present value of the expenditures expected to be required to 
           settle the obligation, using a pre-tax discount rate that reflects current market assessments 
           of the time value of money and the risks specific to the obligation. The increase in the provision 
           due to the passage of time is recognised as a finance cost. 
 1.2.19   Restoration and rehabilitation provision 
           The mining, extraction and processing activities of the Group normally give rise to obligations 
           for site restoration and rehabilitation. Rehabilitation works can include facility decommissioning 
           and dismantling, removal and treatment of waste materials, land rehabilitation, and site restoration. 
           The extent of the work required and the estimated cost of final rehabilitation, comprising 
           liabilities for decommissioning and restoration, are based on current legal requirements, 
           existing technology and the Group's environmental policies, and is reassessed annually. Cost 
           estimates are not reduced by the potential proceeds from the sale of property, plant and equipment. 
 
           Provisions for the cost of each restoration and rehabilitation program are recognised at the 
           time the environmental disturbance occurs. When the extent of the disturbance increases over 
           the life of the operation, the provision and associated asset is increased accordingly. Costs 
           included in the provision encompass all restoration and rehabilitation activity expected to 
           occur. The restoration and rehabilitation provisions are measured at the expected value of 
           future cash flows, discounted to their present value, using a pre-tax discount rate. Discount 
           rates used are specific to the country in which the operation is located or reasonable alternatives 
           if in-country information is not available. The value of the provision is progressively increased 
           over time as the effect of the discounting unwinds, which is recognised in finance charges. 
           Restoration and rehabilitation provisions are also adjusted for changes in estimates. 
 
           When provisions for restoration and rehabilitation are initially recognised, the corresponding 
           cost is capitalised as a decommissioning asset where it gives rise to a future benefit and 
           depreciated over future production from the operation to which it relates. 
 
           Management is required to make significant estimates and assumptions when determining the 
           amount of the restoration and rehabilitation provisions as referred under Note 1.2.28, Critical 
           accounting estimates and judgements. 
 1.2.20   Taxation 
           Income tax for the period comprises current and deferred tax. Income tax is recognised in 
           the statement of profit or loss except to the extent that it relates to items charged or credited 
           directly to equity or to other comprehensive income, in which case the tax consequences are 
           recognised directly in equity and other comprehensive income respectively. Current tax expense 
           is the expected tax payable on the taxable income for the period, using tax rates enacted 
           or substantively enacted at the reporting date, and any adjustment to tax payable in respect 
           of previous years. 
 
           Deferred tax is provided using the statement of financial position liability method, providing 
           for temporary differences between the carrying amounts of assets and liabilities for financial 
           reporting purposes and the amounts used for taxation purposes. 
 
           Deferred tax assets and liabilities are measured at the tax rates that are expected to apply 
           to the period when the asset is realised or the liability is settled based on the tax rates 
           (and tax laws) that have been enacted or substantively enacted at the reporting date. 
 
           A deferred tax asset is recognised only to the extent that it is probable that future taxable 
           profits will be available against which the asset can be utilised. Deferred tax assets are 
           reduced to the extent that it is no longer probable that the related tax benefit will be realised. 
 
           The Group offsets deferred income tax assets and deferred income tax liabilities if, and only 
           if, it has a legally enforceable right to set off current tax assets and current tax liabilities 
           and the deferred income tax assets and deferred income tax liabilities relate to income taxes 
           levied by the same taxation authority on either the same taxable entity or different taxable 
           entities which intend either to settle current tax liabilities and assets on a net basis, 
           or to realise the assets and settle the liabilities simultaneously, in each future period 
           in which significant amounts of deferred tax liabilities or assets are expected to be settled 
           or recovered. 
 
           In respect of taxable temporary differences associated with investments in subsidiaries, associates 
           and jointly controlled entities, deferred tax is provided except where the timing of the reversal 
           of the temporary differences can be controlled by the Group and it is probable that the temporary 
           differences will not reverse in the foreseeable future. 
 
           In respect of deductible temporary differences associated with investments in subsidiaries, 
           associates and jointly controlled entities, deferred tax assets are only recognised to the 
           extent that it is probable that the temporary differences will reverse in the foreseeable 
           future and taxable profit will be available against which the temporary differences can be 
           utilised. Withholding tax is recognised in the statement of profit or loss when dividends 
           or other services which give rise to that withholding tax are declared or accrued respectively. 
           Withholding tax is disclosed as part of current tax. 
 
           Royalties 
           Royalties incurred by the Group comprise mineral extraction costs based on a percentage of 
           sales paid to the local revenue authorities. These obligations arising from royalty arrangements 
           are recognised as current payables and disclosed as part of royalty and selling costs in the 
           statement of profit or loss. 
 
           Royalties and revenue-based taxes are accounted for under IAS 12 when they have the characteristics 
           of an income tax. This is considered to be the case when they are imposed under government 
           authority and the amount payable is based on taxable income - rather than based on quantity 
           produced or as a percentage of revenue. For such arrangements, current and deferred tax is 
           provided on the same basis as described above for other forms of taxation. The royalties incurred 
           by the Group are considered not to meet the criteria to be treated as part of income tax. 
 1.2.21   Employee benefits 
           Provision is made in the financial statements for all short-term employee benefits. Liabilities 
           for wages and salaries, including non-monetary benefits, benefits required by legislation, 
           annual leave, retirement benefits and accumulating sick leave obliged to be settled within 
           12 months of the reporting date, are recognised in trade and other payables and are measured 
           at the amounts expected to be paid when the liabilities are settled. Benefits falling due 
           more than 12 months after the reporting date are measured at the amount the obligation is 
           expected to be settled or discounted to present value using a pre-tax discount rate where 
           relevant or where time value of money is expected to be significant. The Group recognises 
           an expense for contributions to the defined contribution pension fund in the period in which 
           the employees render the related service. 
           Bonus plans 
           The Group recognises a liability and an expense for bonuses. The Group recognises a liability 
           where contractually obliged or where there is a past practice that has created a constructive 
           obligation. These liabilities are recognised in trade and other payables and are measured 
           at the amounts expected to be paid when the liabilities are settled. 
 1.2.22   Leases 
           At inception, the Group assesses whether a contract is or contains a lease. This assessment 
           involves the exercise of judgement whether it depends on a specified asset, whether the Group 
           obtains substantially all the economic benefits from the use of that asset, and whether the 
           Group has the right to direct the use of the asset. For leases that contain one lease component 
           and one or more additional lease or non-lease components, the Group allocates the consideration 
           in the contract to each lease component on the basis of the relative stand-alone price of 
           the lease component and the aggregate stand-alone price of the non-lease components. The lease 
           component is accounted for under the requirements of IFRS 16 and the non-lease component is 
           accounted for using the relevant standard based on the nature of the non-lease component. 
           Right-of-use assets 
           The Group recognises right-of-use assets at the commencement date of the lease (ie, the date 
           the underlying asset is available for use). Right-of-use assets are measured at cost, less 
           any accumulated depreciation and impairment losses, and adjusted for any remeasurement of 
           lease liabilities. The cost of right-of-use assets includes the amount of lease liabilities 
           recognised, initial direct costs incurred, costs to dismantle, restore and remove the right-of-use 
           asset, and lease payments made at or before the commencement date less any lease incentives 
           received. After the commencement date, the right-of-use assets are measured using a cost model. 
           Right-of-use assets are depreciated on a straight-line basis over the shorter of the lease 
           term and the estimated useful lives of the assets. If ownership of the leased asset transfers 
           to the Group at the end of the lease term or the cost reflects the exercise of a purchase 
           option, depreciation is calculated using the estimated useful life of the asset. Right-of-use 
           assets are subject to impairment. Refer Note 1.2.12, Impairments. 
 
           Lease liabilities 
           At the commencement date of the lease, the Group recognises lease liabilities measured at 
           the present value of lease payments to be made over the lease term. The lease payments include 
           fixed payments (including in-substance fixed payments) less any lease incentives receivable, 
           variable lease payments that depend on an index or a rate, and amounts expected to be paid 
           under residual value guarantees. The lease payments also include the exercise price of a purchase 
           option reasonably certain to be exercised by the Group and payments of penalties for terminating 
           a lease, if the lease term reflects the Group exercising the option to terminate. The variable 
           lease payments that do not depend on an index or a rate are recognised as an expense in the 
           period on which the event or condition that triggers the payment occurs. 
 
           In calculating the present value of lease payments, the Group uses the incremental borrowing 
           rate at the lease commencement date if the interest rate implicit in the lease is not readily 
           determinable. After the commencement date, the amount of lease liabilities is increased to 
           reflect the accretion of interest and reduced for the lease payments made. In addition, the 
           carrying amount of lease liabilities is remeasured if there is a modification to the terms 
           and conditions of the lease or if there a lease reassessment. 
           Short-term leases and leases of low-value assets 
           The Group applies the short-term lease recognition exemption to its short-term leases (ie, 
           those leases that have a lease term of 12 months or less from the commencement date and do 
           not contain a purchase option). It also applies the lease of low-value assets recognition 
           exemption to leases of office equipment that are considered to be qualitatively and quantitatively 
           of low value. Lease payments on short-term leases and leases of low-value assets are recognised 
           as expense on a straight-line basis over the lease term. 
 
           Group as a lessor 
           Where the Group is a lessor, it determines at inception whether the lease is a finance or 
           operating lease. When a lease transfers substantially all the risks and rewards of ownership 
           of the underlying asset then the lease is a finance lease; otherwise the lease is an operating 
           lease. 
 
           Where the Group is an intermediate lessor, the interest in the head lease and the sub-lease 
           is accounted for separately and the lease classification of a sub-lease is determined by reference 
           to the Right-of-use-asset arising from the head lease. Income from operating leases is recognised 
           on a straight-line basis over the lease term. 
 1.2.23   Revenue from contracts with customers 
           Revenue comprises net invoiced diamond sales to customers excluding VAT. Diamond sales are 
           made through a competitive tender process and recognised when the Group's performance obligations 
           have been satisfied at the time the buyer obtains control of the diamond(s), at an amount 
           that the Group expects to be entitled in exchange for the diamond(s). Where the Group makes 
           rough diamond sales to customers and retains a right to an interest in their future sale as 
           polished diamonds, the Group records the sale of the rough diamonds but such contingent revenue 
           on the onward sale is only recognised at the date when the polished diamonds are sold or when 
           polished sales prices are mutually agreed between the customer and the Group. 
 
           The following revenue streams are recognised: 
            *    rough diamonds which are sold through a competitive 
                 tender process, partnership agreements and joint 
                 operation arrangements; 
 
 
            *    polished diamonds and other products which are sold 
                 through direct sales channels; 
 
 
            *    additional uplift (on the value from rough to 
                 polished) on partnership arrangements; and 
 
 
            *    additional uplift (on the value from rough to 
                 polished) on joint operation arrangements. 
 
 
 
           The sale of rough diamonds is the core business of the Group, with other revenue streams contributing 
           marginally to total revenue. 
 
           Revenue through joint operation arrangements is recognised for the sale of the rough diamond 
           according to each party's percentage entitlement as per the joint operation arrangement. Contractual 
           agreements are entered into between the Group and the joint operation partner whereby both 
           parties control jointly the cutting and polishing activities relating to the diamond. All 
           decisions pertaining to the cutting and polishing of the diamonds require unanimous consent 
           from both parties. Once these activities are complete, the polished diamond is sold, after 
           which the revenue on the remaining percentage of the rough diamond is recognised, together 
           with additional uplift on the joint operation arrangement. The Group portion of inventories 
           related to these transactions is included in the total inventories balance. 
 
           Revenue through partnership arrangements is recognised for the sale of the rough diamond, 
           with an additional uplift based on the polished margin achieved. Management recognises the 
           revenue on the sale of the rough diamond when it is sold to a third party, as there is no 
           continuing involvement by management in the cutting and polishing process and control has 
           passed to the third party. Revenue from additional uplift is considered to be a variable consideration. 
           This variable consideration will generally be significantly constrained. This is on the basis 
           that the ultimate additional uplift received will depend on a range of factors that are highly 
           susceptible to factors outside the Group's influence. Management recognises revenue on the 
           additional uplift when the polished diamond is sold by the third party or the polished sales 
           prices are mutually agreed between the third party and the Group and the additional uplift 
           is guaranteed. 
 
           Rendering of service 
           Revenue from services relating to third-party diamond manufacturing is recognised in the accounting 
           period in which the services are rendered, when the Group's performance obligations have been 
           satisfied, at an amount that the Group expects to be entitled to in exchange for the services. 
 
           Contract assets 
           A contract asset is the right to consideration in exchange for goods or services transferred 
           to the customer. If the Group transfers goods or services to a customer before the customer 
           pays consideration or before payment is due, a contract asset is recognised for the earned 
           consideration that is conditional. The Group does not have any contract assets as performance 
           and a right to consideration occurs within a short period of time and all rights to consideration 
           are unconditional. 
 
           Contract liabilities 
           A contract liability is the obligation to transfer goods or services to a customer for which 
           the Group has received consideration (or an amount of consideration is due) from the customer. 
           If a customer pays consideration before the Group transfers goods or services to the customer, 
           a contract liability is recognised when the payment is made or the payment is due (whichever 
           is earlier). Contract liabilities are recognised as revenue when the Group performs under 
           the contract. The Group does not have any contract liabilities as the transfer of goods or 
           services performance occurs within a short period of time of receiving the consideration. 
 1.2.24   Interest income 
           Interest income is recognised on a time proportion basis using the effective interest rate 
           method. 
 1.2.25   Dividends 
           Dividends are recognised when the amount of the dividend can be reliably measured and the 
           Group's right to receive payment is established. 
 1.2.26   Finance costs 
           Finance costs are recognised on a time proportion basis using the effective interest rate 
           method. 
 1.2.27   Dividend distribution 
           Dividend distributions to the Group's shareholders are recognised as a liability in the Group's 
           financial statements in the period in which the dividends are approved by the Group's shareholders. 
 1.2.28   Critical accounting estimates and judgements 
           The preparation of the consolidated financial statements requires management to make estimates 
           and judgements and form assumptions that affect the reported amounts of the assets and liabilities, 
           the reported income and expenses during the periods presented therein, and the disclosure 
           of contingent liabilities at the date of the financial statements. Estimates and judgements 
           are continually evaluated and are based on historical experience and other factors, including 
           expectations of future events that are believed to be reasonable under the circumstances. 
 
           The Group makes estimates and assumptions concerning the future and the resulting accounting 
           estimates will, by definition, seldom equal the related actual results. The estimates and 
           assumptions that have a significant risk of causing a material adjustment to the financial 
           results or the financial position reported in future periods are discussed below. 
 
           COVID-19 
           The Group has considered the impact of COVID-19 on its significant accounting judgements and 
           estimates. The Group's main source of estimation uncertainty is in relation to assumptions 
           used for the assessment of impairment and impairment reversal of assets. No further significant 
           estimates have been identified as a result of COVID-19, although the pandemic has increased 
           the level of uncertainty inherent in all future cash flow forecasts. 
 
           Estimates 
           Ore reserves and associated life of mine (LoM) 
           There are numerous uncertainties inherent in estimating ore reserves and the associated LoM. 
           Therefore, the Group must make a number of assumptions in making those estimations, including 
           assumptions as to the prices of diamonds, exchange rates, production costs and recovery rates. 
           Assumptions that are valid at the time of estimation may change significantly when new information 
           becomes available. Changes in the forecast prices of diamonds, exchange rates, production 
           costs or recovery rates may change the economic status of ore reserves and may, ultimately, 
           result in the ore reserves being restated. Where assumptions change the LoM estimates, the 
           associated depreciation rates, residual values, waste stripping and amortisation ratios, and 
           environmental provisions are reassessed to take into account the revised LoM estimate. Refer 
           Note 9, Property, plant and equipment. 
 
           Exploration and evaluation expenditure 
           This policy requires management to make certain estimates and assumptions as to future events 
           and circumstances, in particular whether economically viable extraction operations are viable 
           where reserves have been discovered and whether indications of impairment exist. Any such 
           estimates and assumptions may change as new information becomes available. Refer Note 9, Property, 
           plant and equipment. 
 
           Provision for restoration and rehabilitation 
           Significant estimates and assumptions are made in determining the amount of the restoration 
           and rehabilitation provisions. These deal with uncertainties such as changes to the legal 
           and regulatory framework, magnitude of possible contamination, and the timing, extent and 
           costs of required restoration and rehabilitation activity. Refer Note 22, Provisions, for 
           further detail. 
 
           Judgement 
           Impairment reviews 
           The Group determines if goodwill is impaired at least on an annual basis, while all other 
           significant operations are tested for impairment when there are potential indicators which 
           may require impairment review. This requires an estimation of the recoverable amount of the 
           relevant CGU under review. Recoverable amount is the higher of fair value less costs to sell 
           and value in use. While conducting an impairment review of its assets using value-in-use impairment 
           models, the Group exercises judgement in making assumptions about future rough diamond prices, 
           exchange rates, volumes of production, ore reserves and resources included in the current 
           LoM plans, production costs and macro-economic factors such as inflation and discount rates. 
           Changes in estimates used can result in significant changes to the consolidated statement 
           of profit or loss and consolidated statement of financial position. The results of the impairment 
           testing performed did not indicate any impairments in the current year. Refer Note 12, Impairment 
           testing, for further estimates and judgements applied. 
           The key assumptions used in the recoverable amount calculations, determined on a value-in-use 
           basis, are listed below: 
 
           Valuation basis 
           Discounted present value of future cash flows. 
           LoM and recoverable value of reserves and resources 
           Economically recoverable reserves and resources, carats recoverable and grades achievable 
           are based on management's expectations of the availability of reserves and resources at mine 
           sites and technical studies undertaken by in-house and third-party specialists. Reserves remaining 
           after the current LoM plan have not been included in determining the value in use of the operations. 
           Cost and inflation rate 
           Operating costs for Letšeng are determined based on management's experience and the use 
           of contractors over a period of time whose costs are fairly reasonably determinable. Mining 
           and processing costs in the short to medium term have been based on the agreements with the 
           relevant contractors. In the longer term, management has applied local inflation rates of 
           4% to 5.3% (2019: 4% to 6%) for operating costs in addition to a depth escalation factor for 
           mining costs as a result of mining in deeper areas within both pits. 
 
           Capital costs in the short-term has been based on management's capital program after which 
           a fixed percentage of operating costs have been applied to determine the capital costs necessary 
           to maintain current levels of operations. 
 
           Exchange rates 
           Exchange rates are estimated based on an assessment at current market fundamentals and long-term 
           expectations. The US dollar/Lesotho loti (LSL) exchange rate used was determined with reference 
           to the closing rate at 31 December 2020 of LSL14.69 (31 December 2019: LSL13.98). 
 
           Diamond prices 
           The diamond prices used in the impairment test have been set with reference to recent prices 
           achieved, recent market trends and the Group's medium-term forecast. Long-term diamond price 
           escalation reflects the Group's assessment of market supply/demand fundamentals. 
 
           Discount rate 
           The discount rate of 10.8% for revenue (2019: 11.2%) and 14.3% for costs (2019: 14.7%) used 
           for Letšeng represents the before-tax risk-free rate adjusted for market risk, volatility 
           and risks specific to the asset and its operating jurisdiction. 
 
           Market capitalisation 
           In the instance where the Group's asset carrying values exceed market capitalisation, this 
           results in an indicator of impairment. The Group believes that this position does not represent 
           an impairment as all significant operations were assessed for impairment during the year and 
           no impairments were recognised. 
 
           Sensitivity 
           The value in use for Letšeng indicated sufficient headroom, and the further changes to 
           key assumptions which could result in impairment are disclosed in Note 12, Impairment testing. 
 
           Capitalised stripping costs (deferred waste) 
           Waste removal costs (stripping costs) are incurred during the development and production phases 
           at surface mining operations. Furthermore, during the production phase, stripping costs are 
           incurred in i) the production of inventory and ii) in the creation of future benefits by improving 
           access and mining flexibility in respect of the ore to be mined, (the 'stripping activity 
           asset'). Judgement is required to distinguish between these two activities at Letšeng. 
           The orebody needs to be identified in its various separately identifiable components. An identifiable 
           component is a specific volume of the orebody that is made more accessible by the stripping 
           activity. Judgement is required to identify and define these components (referred to as 'cuts'), 
           and also to determine the expected volumes (tonnes) of waste to be stripped and ore to be 
           mined in each of these components. These assessments are based on a combination of information 
           available in the mine plans, specific characteristics of the orebody and the milestones relating 
           to major capital investment decisions. 
 
           Judgement is also required to identify a suitable production measure that can be applied in 
           the calculation and allocation of production stripping costs between inventory and the stripping 
           activity asset. The ratio of expected volume (tonnes) of waste to be stripped for an expected 
           volume (tonnes) of ore to be mined for a specific component of the orebody, compared to the 
           current period ratio of actual volume (tonnes) of waste stripped to the volume (tonnes) of 
           ore mined is considered to determine the most suitable production measure. 
 
           These judgements and estimates are used to calculate and allocate the production stripping 
           costs to inventory and/or the stripping activity asset(s). Furthermore, judgements and estimates 
           are also used to apply the stripping ratio calculation in determining the amortisation of 
           the stripping activity asset. Refer Note 9, Property, plant and equipment, for further detail. 
 
           Share-based payments 
           Judgement is applied by management in determining whether the share options relating to employees 
           who resigned before the end of the service condition period have been cancelled or forfeited 
           in light of their leaving status. Where employees do not meet the requirements of a good leaver 
           as per the rules of the long-term incentive plan (LTIP), no award will vest and this will 
           be treated as cancellation by forfeiture. The expenses relating to these charges previously 
           recognised are then reversed. Where employees do meet the requirements of a good leaver as 
           per the rules of the LTIP, some or all of an award will vest and this will be treated as a 
           modification to the original award. The future expenses relating to these awards are accelerated 
           and recognised as an expense immediately. Refer Note 28, Share-based payments, for further 
           detail. 
 
           Identifying uncertainties over tax treatments 
           An amended tax assessment was issued to Letšeng by the Lesotho Revenue Authority (LRA) 
           in December 2019, contradicting the application of certain tax treatments in the current Lesotho 
           Income Tax Act 1993. In March 2020, Letšeng lodged an objection to the assessment, which 
           was supported by the opinion of senior counsel, together with an application for the suspension 
           of payment. The suspension of payment was accepted. The LRA has subsequently lodged an application 
           to the Lesotho High Court pertaining to this matter, to which Letšeng is opposing. The 
           matter has been set down for hearing in August 2021. 
 
           Management do not believe an uncertain tax position exists as: 
            *    there is no ambiguity in the application of the 
                 Lesotho Income Tax Act; 
 
 
            *    there has been no change in the application of the 
                 Income Tax Act and resulting tax; and 
 
 
            *    senior counsel advice, which is legally privileged, 
                 has been obtained and reflects good prospects of 
                 success in setting aside the amended tax assessment. 
 
 
 
           No provision or contingent liability, relating to the amended tax assessment in question, 
           is required to be raised in the 2020 Annual Financial Statements. 
 
           Equipment and service lease 
           The major components of Letšeng's ore-extraction mining activities are outsourced to 
           a mining contractor. The mining contractor performs these functions using their own equipment. 
           Management applied judgement when evaluating whether the contract between Letšeng and 
           the mining contractor contained a lease. While it was concluded there was a lease, lease payments 
           are variable in nature as the lease payment vary based on the tonnes of ore and waste mined 
           and hence no right of use asset or liability could be measured. A portion of the lease payment 
           is expensed in the consolidated statement of profit or loss and the portion relating to waste 
           removal/stripping costs is capitalised to the waste stripping asset in the proportions referred 
           to under the estimate and judgements applied to the Capitalised stripping costs (deferred 
           waste) above. Refer Note 25, Commitments and contingencies.

  COVID-19 standing costs 
   In compliance with the Government of Lesotho's lockdown order, Letšeng temporarily 
   suspended 
   operations between 28 March and 26 April and placed the mine on care and maintenance. After 
   successfully engaging with the Government of Lesotho to designate mining as an essential 
   service, 
   a restart and ramp-up plan was implemented commencing in May, whereby normal production 
   levels 
   for both treatment plants were achieved by 27 May, with incidental waste mining commencing 
   in May and reaching normal levels in July. During the care and maintenance and ramp-up 
   periods 
   where normal waste stripping and carat production levels were disrupted, certain standing 
   fixed mining contract and ore stockpile movement costs incurred were recognised as abnormal 
   costs and have been expensed immediately in the Statement of profit or loss. Of these costs, 
   US$1.0 million related to costs incurred to implement protocols throughout the Group to 
   address 
   the risk and curb the spread of COVID-19.

    1 These expenses consist of mining activities outsourced to a mining contractor. In 2019 the 
    expense incorrectly included the portion of expenses which are capitalised to the Stripping 
    Actvity Asset, the comparatives have been corrected to exclude the capitalised expenses. This 
    did not impact the totals included within the Consolidated Annual Financial Statements nor 
    the earnings per share of 2019. Refer Significant accounting policies Note 1.2.6, Property 
    Plant and equipment, Note 1.2.28, Critical accounting estimates and judgements, Note 9, Property, 
    plant and equipment and Note 19, Lease liabilities. 
    2 Includes services related to the sale of assets. 
    3 Includes contributions to defined contribution plan of US$0.5 million (31 December 2019: 
    US$0.5 million). An average of 381 employees excluding contractors were employed during the 
    period (2019: 425). 
    4 In 2019 the discontinued operation salaries and wages were incorrectly included in this 
    disclosure, however this did not impact the totals included within the Consolidated Annual 
    Financial Statements nor the Earnings per share of 2019. The comparative has been corrected 
    to exclude the salaries and wages related to the discontinued operation. 
    5 Excludes COVID-19 standing costs which are considered as operating costs. 
 
 
 5.   RECLASSIFICATION OF FOREIGN CURRENCY TRANSLATION RESERVE 
       During the prior year the Group abandoned Gem Diamonds Marketing Botswana (Proprietary) Limited, 
       the sales and marketing office for Ghaghoo's diamonds and Gem Diamonds Technology DMCC. As 
       the operations were closed and not sold the closure was classified as an abandonment, which 
       resulted in the recycling of the foreign currency translation reserve. There was no profit 
       or loss on the abandonment.

    2 In 2019 only a portion of the exploration and development asset cost and accumulated depreciation 
    was allocated to the asset held for sale, however this asset only related to the asset held 
    for sale. The previously incorrectly unallocated portion of cost and accumulated depreciation 
    of US$9.4 million, which had a net book value of nil, has been corrected in the prior period

        Buildings comprise office buildings in Maseru, Antwerp, London and Johannesburg. Plant and 
         equipment mainly comprise back-up power generating equipment utilised at Letšeng. Motor 
         vehicles mainly comprise vehicles utilised by contractors at Letšeng. 
 
         Right-of-use assets are depreciated on a straight-line basis over the shorter of its estimated 
         useful life and the lease term. 
 
         During the year, Letšeng entered into a new contract with its existing ore processing 
         contractor. The original contract, which was assessed as containing a lease on adoption on 
         1 January 2019, was cancelled. The new contract was assessed as not containing a lease, as 
         Letšeng no longer retained the right to control the use of the assets associated with 
         the contract. All assets and liabilities associated with the original lease were derecognised. 
         Furthermore, Gem Diamonds Limited (GDL) entered into a new contract for the rental of its 
         office space in London. The new contract was assessed as containing a lease resulting in the 
         recognition of the associated assets and liabilities. The original contract was cancelled, 
         and the associated assets and liabilities were derecognised. Total gains of US$0.2 million 
         relating to the derecognition of leases in the Group have been recognised in the Consolidated 
         Statement of Profit or Loss. Refer Note 19, Lease Liabilities and Note 24.1, Cash generated 
         by operations. 
 
         During the year the Group recognised income of US$0.3 million (2019: US$0.6 million) from 
         the sub-leasing of office buildings in Maseru. The Group expects to receive the following 
         lease payments from the operating sub-leasing in the following years:

 12.    IMPAIRMENT TESTING 
        Impairment testing 
        Goodwill impairment testing is undertaken on Letšeng Diamonds annually and when 
        there 
        are indications of impairment. The most recent test was undertaken at 31 December 2020. 
        In 
        assessing whether goodwill has been impaired, the carrying amount of Letšeng 
        Diamonds 
        is compared with its recoverable amount. For the purpose of goodwill impairment testing 
        in 
        2020, the recoverable amount for Letšeng Diamonds has been determined based on a 
        value-in-use 
        model, similar to that adopted in the past.

        The discount rate is outlined below and represents the nominal pre-tax rate. This rate

  Value in use 
   Cash flows are projected for a period up to the date that the open pit mining is expected 
   to cease in 2034. This is based on the latest available mine plan and is shorter than the 
   mining lease period which extends to 2029 with an exclusive option to renew for a further 
   10 years to 2039. This mine plan takes into account the available reserves and other relevant 
   inputs such as diamond pricing, costs and geotechnical parameters. 
 
   Sensitivity to changes in assumptions 
   The Group will continue to test its assets for impairment where indications are identified. 
 
   Refer Note 1.2.28, Critical accounting estimates and judgements, for further details on impairment 
   testing policies. 
 
   The diamond prices used in the impairment test have been set with reference to recent prices 
   achieved, recent market trends and anticipated market supply and the Group's medium-term forecast. 
   Long-term diamond price escalation reflects the Group's assessment of market supply/demand 
   fundamentals. The valuation of Letšeng at 31 December 2020 exceeded the carrying value 
   by US$83.0 million (31 December 2019: US$86.0 million). The valuation is sensitive to input 
   assumptions particularly in relation to the foreign exchange assumption of the US dollar (US$) 
   to the Lesotho loti (LSL) and the future price growth for diamonds. The Group has assumed 
   an appropriate price increase for its diamonds following the market improvement noted in the 
   diamond prices in the second half of the year. 
 
   A range of alternative scenarios have been considered in determining whether there is a reasonably 
   possible change in the foreign exchange rates in conjunction with a reasonably possible change 
   in the diamond price recovery, which would result in the recoverable amount equating to the 
   carrying amount. A 10% strengthening of the LSL to the US$ to US$1:LSL13.20 or a further reduction 
   of 9% to the starting diamond prices would result in the recoverable amount equating to the 
   carrying value, with other valuation assumptions remaining the same. 
 
   As a result, no impairment charge was recognised during the year.

  Based on the nature of the Group's client base, other financial assets and the negligible 
   exposure to credit risk, the expected credit loss is insiginificant and has no impact on the 
   Group.

  The amounts reflected in the financial statements approximate fair value due to the short-term 
   maturity and nature of cash and short-term deposits.

   deposits are generally call deposit accounts and earn interest at the respective short-term 
   deposit rates. 
   The Group's cash surpluses are deposited with major financial institutions of high-quality 
   credit standing predominantly within Lesotho and the United Kingdom. 
 
   At 31 December 2020, the Group had US$60.8 million (31 December 2019: US$69.9 million) of 
   undrawn facilities, representing the LSL500.0 million (US$34.0 million) three-year unsecured 
   revolving working capital facility at Letšeng, the Letšeng ZAR100.0 million (US$6.8

 16.    ASSETS HELD FOR SALE 
         In line with the strategic objective to dispose of non-core assets, the Board and Management 
         remain committed to the sale of Gem Diamonds Botswana (Pty) Ltd which owns the Ghaghoo Diamond 
         Mine. The binding agreement that Gem Diamonds entered into in June 2019 for the sale of 100% 
         of the share capital of GDB lapsed due to certain suspensive conditions not having been met, 
         however Management again opened the process to other prospective buyers during the year and 
         has entered into an exclusivity arrangement with an interested party with whom potential sale 
         discussions are continuing. The sales process faced considerable delays in 2020 largely due 
         to the impact of COVID-19 and in particular the related travel restrictions that prohibited 
         site visits which had been requested for due diligence purposes. This process is expected 
         to be concluded in 2021. 
         During the year, some consumable inventory items were written off relating to expired explosives 
         and plant consumables; and spares and accessories for automotives no longer on site. 
 
         The asset held for sale is carried at carrying value which is lower than fair value less costs 
         to sell. The fair value is based on unobservable market offers from potential buyers for the 
         disposal group, accordingly the non-recurring fair value measurement is included in level 
         3 of the fair value hierarchy. 
 
         The trading results of the operation continue to be classified as a discontinued operation 
         held for sale and are presented as follows:

  LSL215.0 million (US$14.6 million) bank loan facility at Letšeng Diamonds 
   This loan comprises two tranches of debt as follows: 
    *    Tranche 1: South African rand denominated ZAR180.0 
         million (US$12.2 million) debt facility supported by 
         the Export Credit Insurance Corporation (ECIC) (five 
         years tenure); and 
 
 
    *    Tranche 2: Lesotho loti denominated LSL35.0 million 
         (US$2.4 million) term loan facility without ECIC 
         support (five years and six months tenure). 
 
 
 
   The loan is an unsecured project debt facility which was signed jointly with Nedbank and the 
   ECIC on 22 March 2017 to fund the construction of the Letšeng mining support services 
   complex. The loan is repayable in equal quarterly payments which commenced in September 2018. 
   At year end LSL76.3 million (US$5.2 million) (31 December 2019: LSL133.7 million (US$9.6 million)) 
   remains outstanding. 
 
   The South African rand-based interest rates for the facility at 31 December 2020 are: 
    *    Tranche 1: 10.10% (31 December 2019: 9.95%); and 
 
 
    *    Tranche 2: 6.50% (31 December 2019: 13.55%). 
 
 
 
   The South African prime lending rate has reduced materially during the year due to the South 
   African Reserve Bank reducing the repo rate to provide relief during the COVID-19 pandemic. 
 
   Total interest for the year on this interest-bearing loan was US$0.6 million (31 December 
   2019: US$2.2 million). 
 
   US$30.0 million (2019: US$45.0 million) bank loan facility at Gem Diamonds Limited 
   This facility was a three-and-a-half-year revolving credit facility (RCF) with Nedbank Capital 
   which consisted of two tranches: 
    *    Tranche 1: related to the Ghaghoo US$25.0 million 
         debt whereby capital repayments commenced in 
         September 2018 with final repayment made on 31 
         December 2020; and 
 
 
    *    Tranche 2: this tranche of US$20.0 million related to 
         an RCF which included an upsize mechanism whereby the 
         tranche increased by a ratio of 0.6:1 for every 
         repayment made under Tranche 1. 
 
 
 
   Upon expiry of the RCF on 31 December 2020, it was rolled into a US$30.0 million facility 
   with no tranches for a period of 12 months. The facility will expire on 31 December 2021. 
 
   At year end US$Nil million (31 December 2019: US$10.0 million) had been drawn down under the 
   facility under Tranche 1 and US$10.0 million (31 December 2019: US$2.0 million) under Tranche 
   2 which was rolled into a new US$30.0 million RCF. This resulted in US$20.0 million remaining 
   undrawn under the new RCF. Facility rolling fees of US$0.3 million were incurred, which were 
   capitalised to the loan balance, resulting in the disclosure of a net US$9.7 million loan 
   balance. The capitalised rolling fees will be amortised and accounted for as finance costs 
   within profit or loss over the period of the facility (2020: nil). The US dollar-based interest 
   rate for this facility at 31 December 2020 is 4.72% (31 December 2019: 6.44%). 
 
   Total interest for the year on this interest-bearing RCF was US$1.2 million (31 December 2019: 
   US$1.7 million). 
 
   ZAR12.8 million (US$0.9 million) Asset-Based Finance facility 
   In January 2019, the Group, through its subsidiary, Gem Diamond Technical Services, entered 
   into a ZAR12.8 million (US$0.9 million) Asset Based Finance (ABF) facility with Nedbank Limited 
   for the purchase of a mobile X-Ray transmission machine (the asset). The asset serves as security 
   for the facility. At year end ZAR8.6 million (US$0.6 million) remains outstanding (31 December 
   2019: ZAR 10.9 million, US$0.8 million). The facility is repayable over five years and bears 
   interest at the South African Prime Lending rate, which was 7.00% at 31 December 2020 (31 
   December 2019: 10.00%). 
 
   Total interest for the year on this interest-bearing ABF was US$0.1 million (31 December 2019: 
   US$0.1 million). 
 
   ZAR14.5 million insurance premium finance 
   The Group through its subsidiary Letšeng Diamonds, entered into a LSL14.5 million (US$1.0 
   million) 12-month funding agreement with Premium Finance Partners (Proprietary) Limited for 
   insurance premium finance for its annual Asset All Risk insurance premium. At year end LSL7.5 
   million (US$0.5 million) remains outstanding. The funding is repayable in 12-monthly instalments 
   and bears a fixed interest rate of 2.95%. Total interest on this funding is LSL0.4 million 
   (US$25.9 thousand) of which LSL0.3 million (US$18.9 thousand) was paid during the year. 
 
   ZAR1.8 million insurance premium finance 
   The Group through its subsidiary Gem Diamonds Technical Services, entered into a ZAR1.8 million 
   (US$0.1 million) 12-month funding agreement with Premium Finance Partners (Proprietary) Limited 
   for its annual Group Umbrella Liability insurance premium. At year end US$64.3 thousand remains 
   outstanding. The funding is repayable in 10-monthly instalments and bears interest at a fixed 
   rate of 2.50%. Total interest on this funding is ZAR45.2 thousand (US$2.7 thousand) of which 
   ZAR18.3 thousand (US$1.1 thousand) interest was paid during the year. 
 
   Other facilities 
   The Group through its subsidiary Letšeng Diamonds, has a LSL500.0 million (US$34.0 million) 
   three-year unsecured revolving working capital facility jointly with Standard Lesotho Bank 
   and Nedbank Capital, which was renewed in July 2018 and expires in July 2021. The facility 
   is expected to be renewed during 2021. There was no draw down of this facility at year end. 
 
   The Group, through its subsidiary, Letšeng Diamonds, has a ZAR100.0 million (US$6.8 million) 
   overdraft facility with Nedbank Limited (acting through its Nedbank Corporate and Investment 
   Banking division). There was no draw down of this facility at year end.

  1 The severance pay benefits arise due to legislation within the Lesotho jurisdiction, requiring 
   that two weeks of severance pay be provided for every completed year of service, payable on 
   retirement. 
   2 These amounts are mainly non-interest bearing and are settled in accordance with terms agreed 
   between the parties. 
 
   Royalties consist of a levy paid to the Government of the Kingdom of Lesotho on the value 
   of diamonds sold by Letšeng. 
 
   In November, Letšeng declared a LSL400.0 million dividend (US$24.8 million), of which 
   LSL150.0 million remains unpaid at year end (US$10.2 million). The dividend payable to the 
   Non-controlling interest represents 30% of the unpaid dividend, payable to the Government 
   of Lesotho. 
 
   The carrying amounts above approximate fair value.

  Rehabilitation provisions 
   The provisions have been recognised as the Group has an obligation for rehabilitation of the 
   mining areas. The provisions have been calculated based on total estimated rehabilitation 
   costs, discounted back to their present values over the LoM at the mining operations. The 
   pre-tax discount rates are adjusted annually and reflect current market assessments. 
 
   In determining the amounts attributable to the rehabilitation provision at the Lesotho mining 
   area, management used a discount rate of 9.7% (31 December 2019: 6.7%), estimated rehabilitation 
   timing of 15 years (31 December 2019: 17 years) and an inflation rate of 5.3% (31 December 
   2019: 5.0%). At the Botswana mining area, management used the available estimated costs to 
   rehabilitate, considering its care and maintenance state. In addition to the changes in the 
   discount rates, inflation and rehabilitation timing, the (decrease)/increase in the provision 
   at Letšeng and Ghaghoo (Refer Note 16, Asset held for sale) respectively is attributable 
   to the annual reassessment of the estimated closure costs performed at the operations together 
   with the ongoing rehabilitation spend during the year at Letšeng.

  The Group has not recognised a deferred tax liability for all taxable temporary differences 
   associated with investments in subsidiaries because it is able to control the timing of dividends 
   and only part of the temporary difference is expected to reverse in the foreseeable future. 
   The gross temporary difference in respect of the undistributed reserves of the Group's subsidiaries 
   for which a deferred tax liability has not been recognised is US$97.1 million (31 December 
   2019: US$127.9 million). 
 
   The Group has estimated tax losses of US$34.0 million (31 December 2019: US$27.5 million). 
   All tax losses are generated in jurisdictions where tax losses do not expire. No deferred 
   tax assets were recognised on these losses.

 25.    COMMITMENTS AND CONTINGENCIES 
        Commitments 
        Mining leases 
        Mining lease commitments represent the Group's future obligation arising from agreements 
        entered 
        into with local authorities in the mining areas that the Group operates. 
        The period of these commitments is determined as the lesser of the term of the 
        agreement, 
        including renewable periods, or the LoM. The estimated lease obligation regarding the 
        future 
        lease period, accepting stable inflation and exchange rates, is as follows: 
  - Within one year                                                                                     162        149 
  - After one year but not more than five years                                                         695        862 
  - More than five years                                                                                993      1 821

                                                                                                      1 850      2 832 
 -----------------------------------------------------------------------------------------------  ---------  --------- 
 
        Equipment and service lease 
        The Group has entered into lease arrangements for the provision of loading, hauling and 
        other 
        transportation services payable at a fixed rate per tonne of ore and waste mined; power 
        generator 
        equipment payable based on a consumption basis; and rental agreements for various mining 
        equipment 
        based on the fleet utilised. All lease payments relating to this lease are variable in 
        nature. 
        A portion of the lease payment is therefore expensed in the Consolidated statement of 
        profit 
        or loss and the portion relating to waste removal/stripping costs is capitalised to the 
        waste 
        stripping asset in the proportions referred to under the estimate and judgements applied 
        to 
        the Capitalised stripping costs (deferred waste). Refer Note 1.2.28, Critical accounting 
        estimates. 
        The terms of this lease are negotiated during the extension option periods catered for 
        in 
        the agreements or at any time sooner if agreed by both parties. 
 
  - Within one year                                                                                  52 855     59 267 
  - After one year but not more than five years                                                     181 904    254 218

        Letšeng Diamonds Educational Fund 
        In terms of the mining agreement entered into between the Group and the Government of 
        the 
        Kingdom of Lesotho, the Group has an obligation to provide funding for education and 
        training 
        scholarships. The quantum of such funding is at the discretion of the Letšeng 
        Diamonds 
        Education Fund Committee. 
  - Within one year                                                                                      37         39

        Capital expenditure 
  Approved but not contracted for                                                                     1 091      3 299 
  Approved and contracted for                                                                           372      1 490

 -----------------------------------------------------------------------------------------------  ---------  --------- 
 
  The main capital expenditure approved relates to investment in continued tailings storage 
   extension of US$1.0 million (31 December 2019: US$0.6 million), investment at the mining fleet 
   maintenance workshop of US$0.3 million (31 December 2019: nil) and the purchase of safety 
   equipment and vehicles US$0.1 million. The expenditure is expected to be incurred over the 
   next 12 months but will be assessed in line with the uncertainty presented by the COVID-19 
   pandemic. 
 
   Contingent rentals - Alluvial Ventures 
   The contingent rentals represent the Group's obligation to a third party (Alluvial Ventures) 
   for operating a third plant on the Group's mining property at Letšeng Diamonds. The rental 
   is determined when the actual diamonds mined by Alluvial Ventures are sold. The agreement 
   is based on 39.5% to 60% of the value (after costs) of the diamonds recovered by Alluvial 
   Ventures and is limited to US$1.4 million per individual diamond. As at the reporting date, 
   such future sales cannot be determined. 
 
   Contingencies 
   The Group has conducted its operations in the ordinary course of business in accordance with 
   its understanding and interpretation of commercial arrangements and applicable legislation 
   in the countries where the Group has operations. In certain specific transactions, however, 
   the relevant third party or authorities could have a different interpretation of those laws 
   and regulations that could lead to contingencies or additional liabilities for the Group. 
   Having consulted professional advisers, the Group has identified possible disputes approximating 
   US$0.2 million (December 2019: US$0.2 million). 
 
   The Group monitors possible tax claims within the various jurisdictions in which the Group 
   operates. Management applies judgement in identifying uncertainties over tax treatments and 
   concluded that there were no uncertain tax treatments relating to the current year. Refer 
   Note 1.2.28, Critical accounting estimates and judgements. There remains a risk that further 
   tax liabilities may potentially arise. While it is difficult to predict the ultimate outcome 
   in some cases, the Group does not anticipate that there will be any material impact on the 
   Group's results, financial position or liquidity.

 27.          FINANCIAL RISK MANAGEMENT 
               Financial risk factors 
               The Group's activities expose it to a variety of financial risks: 
                *    market risk (including commodity price risk, foreign 
                     exchange risk and interest rate risk); 
 
 
                *    credit risk; and 
 
 
                *    liquidity risk. 
 
 
 
               The Group's overall risk management programme focuses on the unpredictability of financial 
               markets and seeks to minimise potential adverse effects on the Group's financial performance. 
 
               Risk management is carried out under policies approved by the Board of Directors. The Board 
               provides principles for overall risk management, as well as policies covering specific areas, 
               such as foreign exchange risk, interest rate risk, credit risk, use of derivative financial 
               instruments and non-derivative financial instruments, and investing excess liquidity. 
 
               There have been no changes to the financial risk management policy since the prior year. 
 
               Capital management 
               For the purpose of the Group's capital management, capital includes the issued share capital, 
               share premium and liabilities on the Group's statement of financial position. The primary 
               objective of the Group's capital management is to ensure that it maintains a strong credit 
               rating and healthy capital ratios in order to support its business and maximise shareholder 
               value. The Group manages its capital structure and makes adjustments to it, in light of changes 
               in economic conditions. To maintain or adjust the capital structure, the Group may issue new 
               shares or restructure its debt facilities. The management of the Group's capital is performed 
               by the Board. 
 
               The Group's capital management, among other things, aims to ensure that it meets financial 
               covenants attached to its interest-bearing loans and borrowings. Breaches in meeting the financial 
               covenants would permit the bank to immediately call loans and borrowings. There have been 
               no breaches of the financial covenants in the current year. 
 
               At 31 December 2020, the Group had US$60.8 million (31 December 2019: US$69.9 million) of 
               undrawn debt facilities and continues to have the flexibility to manage the capital structure 
               more efficiently by the use of these debt facilities, thus ensuring that an appropriate gearing 
               ratio is achieved. 
 
               Refer Note 18, Interest bearing loans and borrowings for detail on the debt facilities in 
               the Group.

                                                                environment, which has been impacted 
                                                                by the COVID-19 pandemic. 
        b)                          Credit risk 
                                    The Group's potential concentration of credit risk consists mainly of cash deposits with 
                                    banks, 
                                    trade receivables and other receivables. The Group's short-term cash surpluses are placed 
                                    with banks that have investment grade ratings, to minimise the exposure to credit risk to 
                                    the lowest level possible from the perspective of the Group's cash and cash equivalents. 
                                    The 
                                    maximum credit risk exposure relating to financial assets is represented by the carrying 
                                    value 
                                    as at the reporting dates. 
                                    The Group considers the credit standing of counterparties when making deposits to manage 
                                    the 
                                    credit risk. 
 
                                    Considering the nature of the Group's ultimate customers and the relevant terms and 
                                    conditions 
                                    entered into with such customers, the Group believes that credit risk is limited as the 
                                    customers 
                                    pay and settle their accounts on the date of receipt of goods. 
 
                                    No other financial assets are impaired or past due and accordingly, no additional 
                                    analysis 
                                    has been provided. 
                                    The Group did not hold any form of collateral or credit enhancements for its credit 
                                    exposures 
                                    during the 31 December 2020 and 31 December 2019 financial reporting periods. 
        c)                          Liquidity risk 
                                    Liquidity risk arises from the Group's inability to obtain the funds it requires to 
                                    comply 
                                    with its commitments including the inability to sell a financial asset quickly at a price 
                                    close to its fair value. Management manages the risk by maintaining sufficient cash, 
                                    marketable 
                                    securities and ensuring access to financial institutions and shareholding funding. This 
                                    ensures 
                                    flexibility in maintaining business operations and maximises opportunities. The Group has 
                                    available debt facilities of US$60.8 million at year end (2019: US$69.9 million).

               The long-term incentive plans are described below: 
 
               Long-term incentive plan (LTIP) 
               Certain key employees are entitled to a grant of options, under the LTIP of the Company. The 
               vesting of the options is dependent on employees remaining in service for a prescribed period 
               (normally three years) from the date of grant. The fair value of share options granted is 
               estimated at the date of the grant using an appropriate simulation model, taking into account 
               the terms and conditions upon which the options were granted. It takes into account projected 
               dividends and share price fluctuation co-variances of the Company. 
 
               There is a nil or nominal exercise price for the options granted. The contractual life of 
               the options is 10 years and there are no cash settlement alternatives. The Company has no 
               past practice of cash settlement. 
 
               The Company's LTIP policy is reviewed every 10 years. 
 
               LTIP 2007 Award 
               Under the 2007 LTIP rules, there are four awards where options are still outstanding. 
 
               All four awards were awarded on the following basis: 
 
               To key employees (excluding Executive Directors): 
                *    the awards vest over a three-year period in tranches 
                     of a third of the award each year; 
 
 
                *    the vesting of the award is dependent on service 
                     conditions and certain performance targets being met 
                     for the same three-year period (classified as 
                     non-market conditions); 
 
 
                *    if the performance or service conditions are not met, 
                     the options lapse; 
 
 
                *    the performance conditions relating to the non-market 
                     conditions are not reflected in the fair value of the 
                     award at grant date; 
 
 
                *    once the awards vest, they are exercisable for seven 
                     years (ie. contractual term is 10 years); and 
 
 
                *    the vested awards are equity settled. 
 
 
 
               To Executive Directors: 
                *    the awards vest over a three-year period; 
 
 
                *    the vesting of the award is dependent on service 
                     conditions and both market and non-market performance 
                     conditions; 
 
 
                *    75% of the awards granted are subject to non-market 
                     conditions and 25% to market conditions by reference 
                     to the Company's total shareholder return (TSR) as 
                     compared to a group of principal competitors; 
 
 
                *    if the performance or service conditions are not met, 
                     the options lapse; 
 
 
                *    the performance conditions relating to the non-market 
                     conditions are not reflected in the fair value of the 
                     award at grant date; 
 
 
                *    once the awards vest, they are exercisable for seven 
                     years (ie. contractual term is 10 years); and 
 
 
                *    the vested awards are equity settled. 
 
 
 
               The fair value of the Nil value awards is based on the observable Gem Diamonds Limited share 
               price on the date of award with no adjustments to the price made.

          1 Expected volatility was based on the average annual historic volatility of the Company's 
          share price over the previous three years. 
          2 The relevant risk-free interest rate is taken from a UK Treasury Bond issued which closely 
          matches the lifetime of the option. 
        LTIP 2017 Award 
         Under the 2017 LTIP rules, there are four awards where options are still outstanding. 
 
         All the awards were issued on the same basis as the 2007 LTIP. 
 
         During the current year, one new award was made as follows: 
 
         LTIP 2017 Award - June 2020 
         On 9 June, 1 249 000 nil-cost options were granted to certain key employees and Executive 
         Directors. 180 000 of the options granted relate to market conditions. The options vest after 
         a three-year period and are exercisable between 9 June 2023 and 8 June 2030. If the performance 
         or service conditions are not met, the options lapse. The performance conditions relating 
         to the non-market conditions are not reflected in the fair value of the award at grant date, 
         and therefore the Company will assess the likelihood of these conditions being met with a 
         relevant adjustment to the cumulative charge as required at each financial year end. The fair 
         value of the nil-cost options is GBP0.15 (US$0.19). Of the 1 249 000 options originally granted, 
         1 229 356 are still outstanding following the resignation of a number of employees, the lapsing 
         of awards due to certain performance conditions not having been met and management's estimates 
         of the vesting of the remaining tranches. 
 
         The following table reflects details of all the awards within the 2017 LTIP that remain outstanding: 
                            LTIP June 2020   LTIP March 2019   LTIP March 2018                    LTIP July 2017

         In September 2017, 47 200 shares which were previously held in the Company Employee Share 
         Trust were granted to certain key employees involved in the Business Transformation of the 
         Group. The Company Employee Share Trust was deregistered in 2017 following the grant of these 
         shares. The fair value of the award was valued at the share price of the Company at the date 
         of the award of GBP0.71 (US$0.96). These shares vested on 18 March 2019 and became immediately 
         exercisable. The fair value of these outstanding awards at 31 December 2020 was GBP0.41 (2019: 
         GBP0.41). The shares outstanding at the end of the year are as follows:

BASIS FOR PREPARATION

Reporting entities

This report includes payments to governments made by subsidiaries in the Group that are engaged in extractive activities. During the 2020 financial reporting period, extractive activities were conducted in Lesotho while the operation in Botswana was under care and maintenance. All payments made in relation to the Botswana entity were under the materiality level and therefore not reported.

Extractive activities

Extractive activities relate to the exploration, prospection, discovery, development and extraction of minerals, oil, natural gas deposits or other materials. Gem Diamonds Limited, through its subsidiaries, is engaged in diamond mining activities.

Scope of payments

The report discloses only those significant payments made to governments arising from extractive activities.

Government

Taxes

These are payments on the entity's income, production, or profits, excluding taxes levied on consumption such as value added taxes, personal income taxes or sales taxes in line with in-country legislation.

Royalties

These are payments for the right to extract diamonds and are determined on percentage of sales in terms of in-country legislation and/or mining lease agreements.

Dividends

These are dividend payments, other than dividends paid to a government as an ordinary shareholder of an entity unless paid in lieu of production entitlements or royalties. There were no dividend payments of this nature to governments for the year ended 31 December 2020.
