About Hochschild Mining plc:

Hochschild Mining plc is a leading precious metals company listed on the London Stock Exchange (HOCM.L / HOC LN) with a primary focus on the exploration, mining, processing and sale of silver and gold. Hochschild has over fifty years' experience in the mining of precious metal epithermal vein deposits and currently operates three underground epithermal vein mines, two located in southern Peru and one in southern Argentina. Hochschild also has numerous long-term projects throughout the Americas.

CHAIRMAN'S STATEMENT

Hochschild's performance in 2018 demonstrates the rigorous execution of our strategy and is testament to the passion and commitment of all our people. Whilst maintaining strict focus on safety and environmental performance, a sixth year of production growth has been complimented by exciting results from our brownfield exploration programme especially at our flagship Inmaculada mine. Significant new veins have been discovered at Inmaculada, supporting a life-of-mine extension unprecedented at Hochschild since the IPO. Such an increase allows our employees, management and shareholders to plan ahead with a higher degree of certainty and fundamentally changing how our company is perceived. 2018 was also marked by the repayment of our senior notes, delivering on our commitment to prioritise the repayment of debt and strengthen our financial position. With further solid cashflow and a comfortable balance sheet position, the Board is pleased to recommend a final dividend of 1.959 cents per share ($10 million).

At the operations we delivered record output, with a record contribution from Inmaculada and a significant increase in production from Pallancata. Our cost position has remained under control and despite a deteriorating price environment in the second half of the year, we were still able to generate healthy cashflow. Over the year, we have therefore been able to repay a further $198 million in debt including, the early redemption of our senior bonds in January 2018. This bond repayment will allow us to save materially on our interest payments going forward, giving us added flexibility to sustain the commitment to our various exploration programmes, execute a number of attractive option agreements and continue to return capital to our shareholders.

Our company is always evolving and a commitment to a responsible and innovative operational approach has to be balanced by a disciplined focus on the financial realities of our business. Consequently, the decision to place our oldest mine, Arcata, on care and maintenance following an extensive review, has been a difficult one for our management but is a necessary result of declining silver prices. Exploration is expected to continue at the deposit and it is to be hoped that higher commodity prices or a sufficient improvement in geology would justify a restart in the future.

Our brownfield programme remains the key pillar of our growth strategy and excellent progress was made at Inmaculada in 2018. Drilling yielded over one million gold equivalent ounces of inferred resources and also demonstrated that this rich district could continue to deliver economic resources and therefore mine life extensions for many years to come. We are confident that the momentum can be maintained this year at Inmaculada and we can also look forward to an exciting drill programme scheduled later in the year at Pallancata.

Innovation and technology is critical in improving safety, environmental performance and optimising our operations over time. We have recently established innovation as an important input into our strategy with the ultimate aim of working towards the ideal Hochschild mine of the future. During the last few years, we have established a framework targeted throughout our value chain and involving initiatives in exploration, mine planning, mining and mineral processing as well as key support areas. The Board believes that significant progress has been made in 2018 in such areas as long hole drilling, mine planning software and ore sorting testing. We believe that by continuing to invest in such technology initiatives our management can drastically improve our business model in the long-term.

Safety

The importance of our people is paramount and, therefore, nothing takes a higher priority than ensuring their safety. Accidents at our mine sites in late 2017 prompted management to launch a Safety Culture Transformation Plan, an extensive programme comprising: compulsory training on a weekly basis; a suite of employee initiatives to promote safe working; the implementation of risk management systems; and a communications campaign. Despite these efforts, it is deeply regrettable that there were two accidents during 2018 which claimed the lives of three workers. On behalf of the Board, I would like to express our deepest condolences to the families of the victims involved.

We maintain our focus on safety and I am encouraged that the Plan mentioned above is delivering improved results. In particular, during 2018, the number of high potential safety events across our operations almost halved and the number of lost time safety events fell by 36% compared to 2017. The management team, and indeed the Board, are firm in their collective commitment that safety will never be compromised at Hochschild and that every one of us has a part to play in achieving our safety goals.

Environmental Performance

In last year's statement, I talked of the new environmental corporate objective that had been launched to measure the Group's performance in this key area. Our "ECO" score is calculated using a number of performance metrics including water and air quality, the results from regulatory inspections, water consumption and the generation of non-recyclable waste. The stretch target score for the year was set at 4 (out of 6) and I am delighted that this was significantly exceeded by a score of 5.37, a result that is a testament to our people who have risen to the "Green Challenge" that was launched in 2017.

Outlook

Although 2018 was a relatively disappointing year for precious metal prices, the gold price actually held up well versus other commodities with the background of a weaker US dollar proving to be a key influence. Furthermore, whilst silver experienced a challenging year, the prospects for precious metals in 2019 have improved as global financial markets have started to experience a period of volatility. We are confident that our long-term growth strategy based around low cost brownfield exploration, low risk greenfield exploration, optimisation of our early stage projects and a targeted approach to strategic alliances will deliver shareholder value and attractive capital returns for many years to come.

Another record-breaking year of production is of course only achievable through the efforts of our people. I wish to thank them and my fellow Board members for their contributions in making 2018 another successful year. Hochschild has come a long way since the IPO in 2006 and last year, we held a series of discussions surrounding our purpose. It is our belief that we have a responsibility to lead by example and manage our daily operations whilst raising standards in employee safety, employee growth, environmental practices and the development of local communities. We will also aim to constantly develop better practices through the adoption of new technologies that improve our business model. In summary, the core purpose of Hochschild is to be a responsible and innovative mining company committed to a better world.

Eduardo Hochschild, Chairman

19 February 2019

CHIEF EXECUTIVE OFFICER'S STATEMENT

2018 represented a unique milestone for Hochschild as we have redefined our purpose to ensure that it embodies the values and aspirations that define us as a company. It is not only our responsibility to excel in our operations, but to guarantee the safety and wellbeing of our people. We aim to ensure everyone goes home safe and that our people, suppliers, communities and shareholders - our partners - continue to share in future success. We believe that the only way to be successful is through sustainability, working in harmony with the environment and with the local communities where we operate. Our approach to business is underpinned by a desire to leave a sustainable legacy and acknowledging that our purpose is to be a responsible and innovative mining company committed to a better world.

This year also contained operational highlights for Hochschild, including a material life-of-mine increase achieved at the key Inmaculada deposit, further substantial debt repayment, and the generation of strong optionality in our project and acquisition pipeline. Taking these into account alongside another record production performance, continuing strong cost control, robust cashflow generation and a record environmental performance, I believe Hochschild is successfully delivering on its long term strategic goals. Our operational results, however, were overshadowed by the two fatal accidents that claimed the lives of three workers. We have redoubled our efforts to strengthen our safety culture through the implementation of the Safety Culture Transformation Plan and we will continue to work tirelessly to ensure that we achieve our goal of zero fatalities.

Operations

Our operations produced a record 526,650 gold equivalent ounces (39.0 million silver equivalent ounces) in 2018 which represents a sixth year of output increases and improved on our original target for the year of 514,000 gold equivalent ounces (38.0 million silver equivalent ounces). This was delivered at an all-in sustaining cost of $12.6 per silver equivalent ounce ($931 per gold equivalent ounce) which was also within positively revised expectations. Unsurprisingly, the Inmaculada mine played a key role with its own contribution of just over a quarter of a million gold equivalent ounces (also a record) at $731 per gold equivalent ounce. However, we also delivered a material increase at Pallancata (up 22% to 9.4 million silver equivalent ounces) with production from the Pablo vein now successfully ramped up. Finally, despite a collapse in the Argentinian currency and the resulting government re-introduction of export taxes, San Jose was a model of consistency, producing 13.3 million silver equivalent ounces at a cost of $14.5 per silver equivalent ounce.

The Arcata mine started operations in 1964 and has proved to be a resilient deposit with volatile historic production often reinvigorated by brownfield discoveries. In recent years, the operation has had to contend with a two year delay in exploration as well as increasingly narrow and disseminated vein structures. It is a testament to the skill of the operational and geological teams that production has continued running until now with a series of cost efficiencies and new discoveries. Indeed, in 2018 the mine still managed to produce just over 4 million silver equivalent ounces. However, whilst exploration during the year proved to be encouraging, a significant fall in the silver price does not support the operating and capital costs needed to sustain production and has led management to take the difficult decision to place the mine on care and maintenance. The focus for management going forward remains optimising care and maintenance costs whilst minimising inevitable job losses and providing support to those affected by the decision. However, there remains considerable optionality in the area surrounding Arcata. This includes the Azuca project, the newly optioned Condor deposit and additional brownfield potential close to current operations that could lead to a future restart of the processing plant or indeed the mine itself.

Exploration

Hochschild's brownfield exploration programme has started to gain real momentum with the highlight of 2018 undoubtedly being the first campaign at Inmaculada. The Company has been drilling an area to the south east of the original Angela vein and has confirmed the presence of a considerable number of structures, all in close proximity to the current mine infrastructure. In the year as whole, approximately 1.3 million gold equivalent ounces (95 million silver equivalent ounces) of inferred resources have been added, a highly encouraging result which confirms the strong potential in this district and establishes a long life for the Inmaculada operation. In 2019, the team will continue with campaigns scheduled to the north and west of the Angela vein. We can also look forward to a Q2/Q3 start for an exciting set of drill targets to the south of Pallancata at Cochaloma and Palca whilst at San Jose exploration will continue in the area surrounding the mine as well as further investigation of the Aguas Vivas deposit to the north west.

Business Development

The Company's growth strategy has been augmented in 2018 by a series of business development initiatives which we believe will create valuable optionality for the Company. The aim has been to maintain a balanced portfolio of advanced and early stage opportunities using a mix of greenfield drilling and project options with the focus on stable jurisdictions in the Americas. We have signed several agreements including exploration initiatives with Skeena Resources Ltd of Canada for their Snip mine, with Mirasol Resources Ltd in Chile for their Indra and Agni projects, and with a private owner for the Condor deposit, which is located close to Arcata in our Southern Peru Cluster. In addition to this dynamic greenfield strategy, we are also aiming to optimise the ounces we already have in the portfolio at our Volcan, Azuca and Crespo projects with further brownfield exploration and by applying the knowledge we have gained through our innovation programme.

Financial position

Our balance sheet remains in a strong position with the repayment of our bonds in January 2018 and the refinancing of a portion of that debt at attractive rates. Furthermore, despite deteriorating precious metal prices in the second half of the year, cashflow from operations remained robust with our net debt position falling to $77.4 million (31 December 2017: $102.8 million). Overall, the Company repaid approximately $198 million in 2018.

Financial results

The average gold price received in 2018 was flat versus the previous year but this was offset by a 9% fall in the silver price received and therefore despite record production once again, revenue fell by a modest 3% to $704 million (2017: $723 million). The operational all-in sustaining cost of $12.6 per silver equivalent ounce (2017: $12.3 per ounce) was in line with positively revised forecasts and reflected an increased investment in brownfield exploration as well as one-off hydraulic backfill project costs at San Jose, offset by a fall in unit costs in Argentina due to the significant devaluation of the Peso. This resulted in adjusted EBITDA of $268 million (2017: $301 million). Finally, adjusted earnings per share was lower at $0.05 per share (2017: $0.08 per share) with the elevated tax charge and foreign exchange loss resulting from the above-mentioned devaluation offsetting the effects of the reduction in interest costs.

Outlook

We expect attributable production in 2019 to be 457,000 gold equivalent ounces (37 million silver equivalent ounces) assuming the average silver to gold ratio of 81:1. This figure now excludes Arcata and represents a further 2% increase on 2018 (assuming a constant gold/silver ratio of 74x) and will be driven by: 242,000 gold equivalent ounces from Inmaculada; a further increased contribution of 10.2 million silver equivalent ounces from Pallancata with the Pablo vein in full production; and 7.5 million ounces from the dependable San Jose mine. All in sustaining costs for operations are expected at between $960 to $1,000 per gold equivalent ounce ($11.8 to $12.3 per silver equivalent ounce). This forecast includes a $15 million investment at Inmaculada to begin development of the resources discovered in 2018 and the effect of removing the high cost Arcata operation.

The budget for brownfield exploration has increased to approximately $27 million in 2019 with an additional budget of $10 million being assigned to greenfield drilling targets in Peru, Canada and Chile. We will continue to assess early-stage acquisitions as well as advancing existing opportunities whilst also investing in our innovation programme to aid in the delivery of upside in our operations and projects.

Although 2019 has started with a small rise in precious metal prices, cost control will remain a top priority. We look forward to further results from our comprehensive brownfield drilling programme and, in recognition of the success achieved so far, I am pleased to announce the appointment of Oscar Garcia as Vice-President of Brownfield Exploration. We remain confident that our recent history of operational success and low-cost growth can be extended well into the future. Above all, we are committed to a strategy that we believe will achieve our purpose to be a responsible and innovative mining company committed to a better world.

OPERATING REVIEW

OPERATIONS

Note: 2017/2018 equivalent figures calculated using the previous Company gold/silver ratio of 74x. All 2019 forecasts assume the average gold/silver ratio of 81x.

Production

In 2018, Hochschild exceeded its revised full year production guidance of 38.5 million silver equivalent (520,000 gold equivalent ounces). Production was a record 39.0 million silver equivalent ounces (526,650 gold equivalent ounces) comprising 260,436 ounces of gold and 19.7 million ounces of silver. This was mostly due to a record year at Inmaculada as well as higher production from Pallancata. The overall attributable production target for 2019 is 457,000 gold equivalent ounces or 37.0 million silver equivalent ounces.

Costs

All-in sustaining cost from operations in 2018 was $931 per gold equivalent ounce or $12.6 per silver equivalent ounce (2017: $910 per gold equivalent ounce or $12.3 per silver equivalent ounce), improving on the positively revised guidance of between $12.7 and $13.1 per silver equivalent ounce. This was driven by Inmaculada's competitive $731 per gold equivalent ounce (2017: $721 per ounce) in addition to a better result from Pallancata ($12.1 per silver equivalent ounce). Please see page 13 of the Financial Review for further details on costs.

The all-in sustaining cost from operations in 2019 is expected to be between $960 and $1,000 per gold equivalent ounce (or $11.8 and $12.3 per silver equivalent ounce) which excludes Arcata, which is being placed on care and maintenance, and includes an investment of $15 million in development costs to incorporate the newly discovered resources at Inmaculada.

Production

In 2018, Inmaculada delivered record gold equivalent production of 251,090 ounces, a 5% improvement on 2017 (2017: 239,479 ounces) driven mainly by better than expected grades and production efficiencies.

Costs

All-in sustaining costs were in line with expectations at $731 per gold equivalent ounce (2017: $721 per ounce). Despite unit cost per tonne falling moderately versus 2017, the all-in sustaining figure rose slightly due to an increase in capitalised exploration expenses to incorporate resources from the new veins discovered in 2018.

Pallancata

The 100% owned Pallancata silver/gold property is located in the Department of Ayacucho in southern Peru. Pallancata commenced production in 2007. Ore from Pallancata is transported 22 kilometres to the Selene plant for processing.

Production

Pallancata's full year production result was 9.4 million silver equivalent ounces, a 22% improvement versus 2017 (2017: 7.7 million ounces). The increase was driven by the incorporation of the new Pablo vein in the second half of the year with tonnage increasing and grades reducing in line with expectations. In addition, average grades from the mix of material from Pablo, mine developments and ancillary veins was better than planned in the first half of the year.

Costs

All-in sustaining costs were better than guidance at $12.1 per silver equivalent ounce (2017: $10.7 per ounce), mainly due to higher grades from the mix of material from the Pablo vein, developments and ancillary veins in the first half of the year. The AISC figure increased versus 2017, as expected, in line with the ramp up of the wider, but lower-grade Pablo vein.

San Jose

The San Jose silver/gold mine is located in Argentina, in the province of Santa Cruz, 1,750 kilometres south west of Buenos Aires. San Jose commenced production in 2007. Hochschild holds a controlling interest of 51% in the mine and is the mine operator. The remaining 49% is owned by the minority interest, McEwen Mining Inc.

Production

In 2018, San Jose produced 13.3 million silver equivalent ounces (2017: 13.9 million ounces), a 4% reduction versus 2017 due to lower-grades partially offset by an increase in tonnage.

Costs

All-in sustaining costs were $14.5 per silver equivalent ounce (2017: $14.0 per ounce) with the small increase versus last year due to lower grades, the hydraulic backfill project which was completed in the third quarter and the reintroduction of export taxes in September 2018. These factors were partially offset by the strong devaluation of the Argentinian peso during the year (102%)

On 4 September 2018, the Argentinian Government issued an Executive Order establishing a temporary export tax over all goods exported from Argentina, applicable from 4 September 2018 to 31 December 2020. The rate that applies for San Jose's production is AR$3 per U.S. dollar exported.

Arcata

The 100% owned Arcata underground operation is located in the Department of Arequipa in southern Peru. It commenced production in 1964.

Production

Production for the year was 4.2 million silver equivalent ounces (2017: 5.5 million ounces), a result in line with expectations and reflecting significantly reduced tonnage.

On 13 February 2019, Hochschild announced the decision to place the mine on care and maintenance due to the volatile silver price and current geological conditions

Costs

Arcata's full year all-in sustaining cost was $19.6 per silver equivalent ounce (2017: $18.4 per ounce) with the rise resulting from reduced tonnage and investments to find additional resources. Sustaining and development expenditure from 2018 has been expensed due to the decision to place the mine on care and maintenance. Please see the Financial Review page 17 for further details.

EXPLORATION

Inmaculada

In 2018, Hochschild continued the comprehensive surface drilling programme begun in November 2017 with the campaign focusing on the area to the east of the Angela vein. 9,300m of drilling for potential and 65,600m of resource drilling was executed during the year. 17 veins were discovered with the result that 1.3 million gold equivalent ounces or 95 million silver equivalent ounces have been added to the inferred resource base at Inmaculada. All veins are close to the existing Inmaculada infrastructure with good widths and therefore represent significant low cost additions to the future Inmaculada mine plan. Please see the 2018 Resources table on page 49 for further details.

Key intercepts from the campaign are listed below:

In 2019, a 38,000m drilling programme is planned to find potential resources to the east of the Angela vein and also to the west. In addition, the campaign will look to test the continuity of the Angela vein to the north.

Pallancata

Much of the focus for 2018 was on securing exploration permits for 2019 campaigns at Pablo Sur, Palca and Cochaloma. However, approximately 1,100m of potential underground drilling was carried out in Pablo Sur structure to test for a possible extension to the original Pallancata vein, whilst ore control drilling at the Cinthia vein in Ranichico and in Pablo Piso in the fourth quarter added additional resources.

As mentioned above, the 2019 campaign will concentrate on drilling for potential in the Pablo Sur, Palca and Cochaloma structures with over 30,000 metres current scheduled to be carried out and expected to commence in Q2/Q3 2019.

San Jose

At San Jose, inferred resources were added from a drilling campaign close to the mine infrastructure in the south from the Ayelen S.E., Molle, Maia and Guadalupe veins although the winter weather did disrupt progress towards the middle of the year.

Once the weather improved in the third quarter, the programme recommenced with reverse circulation drilling in the Saavedra zone to the south of the mine as well as long drill holes from the mine to look for potential east-west structures. In addition, a potential drilling campaign to the north west to test the polymetallic structure at the Aguas Vivas zone was also carried out. Overall, approximately 16,000m of potential drilling and 6,000m of resource drilling was completed in 2018.

The 2019 programme will focus on further potential drilling at Aguas Vivas as well as an underground long-hole drilling campaign to the south of the current mining area.

Arcata

At Arcata, an underground drilling programme for the year has been focused on areas close to the existing mine infrastructure with potential to be rapidly incorporated into the short-term Arcata mine plan. Just under 28,000 metres of resource drilling was carried out in the 1(st) and 4(th) quadrants targeting the Ruby, Cristina, Rosalia, Pablito East, Vein X, Frida, Pamela New, Cristina, Rosalia, veins whilst almost 15,000 metres of potential drilling was executed in the Tunel 4, Barbara, Tres Reyes, Silvia Yoselin, Pamela New, Soledad and Anomaly North structures.

The current programme continues into 2019 with an 8,000m underground and surface drilling programme to further evaluate the new Quadrant 4 area as well as potential shallower mineralisation at the Alexia, Marion and Mariana veins.

GREENFIELD AND BUSINESS DEVELOPMENT

Hochschild's strategy with regards to its greenfield exploration programme has been to maintain and drill a balanced portfolio of early-stage to advanced opportunities using a combination of earn-in joint ventures, private placements with junior exploration companies and the staking of properties. This strategy is being executed throughout the Americas with opportunities currently being reviewed in Peru, Chile, the US and Canada.

During 2018, a number of projects were drilled including Loro in Chile belonging to Revelo Resources Corp, Moho and Redlitch in Nevada belonging to KA Gold and Fresia in Peru which is 100% owned by Hochschild. There were no significant results to report and therefore, with the exception of Fresia, these options have not been taken up.

To date, options have been secured on properties across the Americas including: the Snip mine in Canada owned by Skeena Resources; the Cobalt project in Canada owned by Cobalt Power Group; the Agni and Indra projects in Chile owned by Mirasol Resources; and the Ferguson Mountain and Mars projects in Nevada owned by Renaissance Gold. In addition, the Company has also secured an option on the Condor project located in Arequipa (Peru) close to the Arcata operation. The deposit current hosts a small private mine and has significant under-explored concessions with 40km of veins already identified. Drilling is expected to commence in 2019.

In 2019, a $10 million budget has been assigned and work will continue on the above-mentioned projects as well superficial geological work and applications for access rights on a number of Peruvian projects.

FINANCIAL REVIEW

The reporting currency of Hochschild Mining plc is U.S. dollars. In discussions of financial performance, the Group removes the effect of exceptional items, unless otherwise indicated, and in the income statement results are shown both pre and post such exceptional items. Exceptional items are those items, which due to their nature or the expected infrequency of the events giving rise to them, need to be disclosed separately on the face of the income statement to enable a better understanding of the financial performance of the Group and to facilitate comparison with prior years.

Revenue

Gross revenue

Gross revenue from continuing operations decreased by 3% to $733.3 million in 2018 (2017: $759.1 million) due to a fall in the average silver price received offsetting small rises in ounces sold of both gold and silver in line with increased production.[7]

Gold

Gross revenue from gold in 2018 increased slightly to $386.2 million (2017: $381.3 million) due to small increase in the total amount of gold ounces sold in 2018. This resulted from increases at the Inmaculada and Pallancata mines offsetting a fall in gold sales from the Arcata mine.

Silver

Gross revenue fell in 2018 to $347.0 million (2017: $377.8 million) mainly due to a 9% decline in the average silver price received. This was partially offset by a small increase in the total amount of silver ounces sold to 22,687 koz (2017: 22,295 koz) resulting from the rise in silver production at Pallancata.

Gross average realised sales prices

The following table provides figures for average realised prices (before the deduction of commercial discounts) and ounces sold for 2018 and 2017:

 
 Average realised prices                Year ended     Year ended

                                     -------------  ------------- 
 Silver ounces sold (koz)                   22,687         22,295 
 Avg. realised silver price ($/oz)            15.3           16.9 
 Gold ounces sold (koz)                     304.51         300.21 
 Avg. realised gold price ($/oz)             1,268          1,270 
-----------------------------------  -------------  ------------- 
 

Commercial discounts

Commercial discounts refer to refinery treatment charges, refining fees and payable deductions for processing concentrate, and are deducted from gross revenue on a per tonne basis (treatment charge), per ounce basis (refining fees) or as a percentage of gross revenue (payable deductions). In 2018, the Group recorded commercial discounts of $29.4 million (2017: $36.9 million) with the decrease explained by the lower production from the concentrate-only Arcata mine. The ratio of commercial discounts to gross revenue in 2018 was 4% (2017: 5%).

Net revenue[8]

Net revenue was $704.3 million (2017 $722.6 million), comprising net gold revenue of $378.8 million (2017: $372.3 million) and net silver revenue of $325.1 million (2017: $349.8 million). In 2018, gold accounted for 54% and silver 46% of the Company's consolidated net revenue (2017: gold 52% and silver 48%).

Costs

Total cost of sales was $531.8 million in 2018 (2017: $549.0 million). The direct production cost excluding depreciation was higher at $363.9 million (2017: $345.4 million) mainly due to higher production volumes at Inmaculada and also at Pallancata due to the ramp up of the Pablo vein and the reclassification of logistics costs of $6.1 million from selling expenses to production costs as a consequence of adopting IFRS 15 Revenue from Contracts with Customers.[11] This was partially offset by costs savings at San Jose due to the high Argentinian peso devaluation. Depreciation in production cost decreased to $164.2 million (2017: $196.2 million) due to the increased mine life at Inmaculada resulting from the strong inferred resource additions. Other items, which principally includes personnel-related provisions and stoppage costs (at San Jose), declined to $1.1 million in 2018 (2017: $3.2 million). Change in inventories was $2.5 million in 2018 (2017: $4.1 million) due to a slight rise in products in process.

Unit cost per tonne

The Company reported unit cost per tonne at its operations of $121.1 per tonne in 2018, a 3% decrease versus 2017 ($125.0 per tonne) due to increased mined tonnage at Pallancata and the depreciation of the Argentine peso offsetting the decline in tonnage at Arcata and inflation in Argentina.

Administrative expenses

Administrative expenses before exceptional items decreased by 11% to $45.8 million (2017: $51.3 million) primarily due to a decrease in personnel expenses.

Exploration expenses

In 2018, exploration expenses increased to $34.4 million (2017: $17.2 million) in line with the overall rise in the Company's investment in brownfield and greenfield exploration. In addition, the Group capitalises part of its brownfield exploration, which mostly relates to costs incurred converting potential resource to the Inferred or Measured and Indicated categories. In 2018, the Company capitalised $9.2 million relating to brownfield exploration compared to $2.3 million in 2017, bringing the total investment in exploration for 2018 to $43.6 million (2017: $19.5 million).

Selling expenses

Selling expenses decreased by 9% versus 2017 to $10.1 million (2017: 11.0 million) due to the reclassification of logistics costs of $6.1 million to cost of sales as a consequence of adopting IFRS 15 (Revenue from Contracts with Customers). This was offset by the reintroduction of export taxes in Argentina from September 2018 ($5.1 million) and moderately higher expenses in line with higher sales volumes.

Other income/expenses

Other income before exceptional items was lower at $8.1 million (2017: $10.2 million) with 2017 income including a one-off gain from the sale of mining rights in Peru for $1.5 million.

Other expenses before exceptional items were higher at $17.1 million (2017: $11.5 million) mainly due to uncollected receivables from Republic Metals Corp of $4.9 million.

Adjusted EBITDA

Adjusted EBITDA decreased by 11% to $268.0 million (2017: $300.8 million) primarily due to the fall in the average silver price received, the reintroduction of export taxes in Argentina in September 2018 and uncollected receivables from Republic Metals Corp of $4.9 million. These were partially offset by costs savings at San Jose due to Argentinian peso devaluation.

Adjusted EBITDA is calculated as profit from continuing operations before exceptional items, net finance costs and income tax plus non-cash items (depreciation and changes in mine closure provisions) and exploration expenses other than personnel and other exploration related fixed expenses.

Finance income

Finance income before exceptional items of $2.0 million decreased from 2017 ($5.9 million) primarily due to the impact of one-off gains in 2017 from the discount of tax credits in Argentina ($1.9 million) and the sale of shares in Mariana Resources ($1.4 million).

Finance costs

Finance costs before exceptional items decreased from $26.1 million in 2017 to $11.2 million in 2018, principally due to the reduction in the interest rate from 7.75% (Senior Notes) to an average of 2.48% (short and medium term loan rates) resulting from the repayment of the Company's Senior Notes. In addition, gross debt was reduced from $353.8 million ($294.8 million of Senior Notes and $59.0 million of short term debt) to $156.0 million (comprising medium-term loan facility of $50.0 million and short-term debt of $106.0 million).

Foreign exchange (losses)/gains

The Group recognised a foreign exchange loss of $8.9 million (2017: $5.3 million loss) as a result of exposures in currencies other than the functional currency - primarily the Argentinean peso which significantly depreciated in 2018 but also the Peruvian sol which also fell moderately.

Income tax

The Company's pre-exceptional income tax charge was $36.5 million (2017: $13.5 million). The 2018 charge includes the negative impact of converting local currency tax basis at a higher FX rate in Argentina and Peru thus reducing future tax shields in dollar terms. The total effective rate before royalties, the Special Mining Tax and the FX impact was 31%, in line with the average statutory rates. The royalties and Special Mining Tax resulted in a charge of $7.2 million, increasing the rate by 10% whilst the impact of local currency devaluation was $12.6 million, increasing the rate further by 26%. Accordingly the final effective tax rate was 67%.

Exceptional items

Exceptional items in 2018 totalled an $11.5 million loss after tax (2017: $0.5 million gain after tax). Exceptional items principally included the payment of the premium of $11.4 million to redeem early the Senior Notes and the reversal of capitalised Senior Notes issuance costs of $4.9 million.

In addition to these items, the exceptional tax effect was a $4.8 million tax gain (2017: $3.3 million tax charge).

---------------------------------------  -------------  -------------  ---------- 
 

Net cash generated from operating activities decreased from $233.9 million in 2017 to $185.9 million in 2018 mainly due to lower EBITDA of $268.0 million (2017: $ 300.8 million) and higher exploration expenses of $34.4 million (2017: $17.2 million).

Net cash used in investing activities increased to $130.0 million in 2018 from $121.1 million in 2017 mainly due to the construction of the hydraulic backfill plant in Argentina, the development of the Pablo vein at Pallancata and higher capitalised exploration.

Cash used in financing activities increased to $228.3 million used from a $4.9 million inflow in 2017, primarily due the repayment of the Company's Senior Notes ($294.8 million) and $3.0 million of short term debt in Argentina. This was partially offset by new short term loans of $100.0 million raised to repurchase the Senior Notes. In addition, $20 million of dividends were paid to Hochschild Mining plc shareholders and $10.3 million to McEwen Mining.

------------------------------------  ------------------  ------------------ 
 

The Group's working capital position increased modestly by $0.6 million from $(64.9) million to $(64.3) million in 2018. The key drivers of the increase were: higher inventories of $1.4 million mainly due to an increase in stockpiles at the Peruvian operations; a decrease in provisions of $12.5 million mainly due to mine closure disbursements and a lower bonus provision; and an increase in income tax receivable of $2.0 million. These effects were partially offset by: lower trade and other receivables of $(4.4) million mainly in San Jose resulting from an improvement in commercial terms; an increase in trade and other payables of $(8.4) million in line with higher costs and capex; and a reduction in other financial assets of $(2.5) million resulting from the embedded derivative associated with provisional pricing within sales.

The Group's reported net debt position was $77.4 million as at 31 December 2018 (31 December 2017: $102.8 million). In the first quarter of 2018, the Company repurchased its Senior Notes ($294.8 million) and raised $150 million in loans to finance the repurchase. This consisted of a short-term loan with Nova Scotia Bank of $50.0 million and a medium term loan with Nova Scotia Bank and Citibank of $100.0 million. During the year, the Company repaid $50 million of the medium-term facility and refinanced the $100 million of short term loans. In addition, short-term debt in Argentina was reduced by $3.0 million.

The financial information for the year ended 31 December 2018 and 2017 contained in this document does not constitute statutory accounts as defined in section 435 of the Companies Act 2006. The financial information for the years ended 31 December 2018 and 2017 have been extracted from the consolidated financial statements of Hochschild Mining plc for the year ended 31 December 2018 which have been approved by the directors on 19 February 2019 and will be delivered to the Registrar of Companies in due course. The auditor's report on those financial statements was unqualified and did not contain a statement under section 498 of the Companies Act 2006.

2 Significant accounting policies

Basis of preparation

The consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (IFRS) as adopted by the European Union (EU) and the Companies Act 2006.

The basis of preparation and accounting policies used in preparing the consolidated financial statements for the years ended 31 December 2018 and 2017 are set out below. The consolidated financial statements have been prepared on a historical cost basis except for the revaluation of certain financial instruments that are measured at fair value at the end of each reporting period, as explained below. These accounting policies have been consistently applied, except for the effects of the adoption of new and amended accounting standard.

The financial statements are presented in US dollars (US$) and all monetary amounts are rounded to the nearest thousand ($000) except when otherwise indicated.

Changes in accounting policy and disclosures

The accounting policies adopted in the preparation of the consolidated financial statements are consistent with those applied in the preparation of the consolidated financial statement for the year ended 31 December 2017. Amendments to standards and interpretations which came into force during the year did not have a significant impact on the Group's financial statements and are as follows:

-- IFRS 15 Revenue from Contracts with Customers, applicable for annual periods beginning on or after 1 January 2018.

The IASB has issued a new standard for the recognition of revenue arising from contracts with customers. The new revenue standard supersedes all current revenue recognition requirements under IFRS.

The new standard is based on the principle that revenue is recognised when control of a good or service transfers to a customer. The Group evaluated recognition and measurement of revenue based on the five-step model in IFRS 15 and has not identified significant financial impacts, hence no adjustments were recorded derived from the adoption of IFRS 15 other than certain reclassifications as explained below.

The Group adopted the new standard from 1 January 2018 applying the simplified transition method and modified retrospective approach. Certain disclosures changed as a result of the requirements of IFRS 15.

The key issues identified, and the Group's views and perspective are set below.

- Embedded derivatives arising from the sales: As discussed in note 2(p), some of the Group's sales of gold and silver contain provisional pricing features which were considered to be embedded derivatives recorded within sales. The fair value is based on the most recent determined estimate of metal content and the estimated forward price that the entity expects to receive at the end of the quotational period stipulated in the contract. The revaluation of provisionally priced contracts is recorded as an adjustment to revenue. IFRS 15 does not change the assessment of the provisional price adjustment, but they are not considered within the scope of IFRS 15, and consequently have to be disclosed separately (refer to note 4).

- Impact of shipping terms: The Group sells a portion of its production on CIF Incoterms and therefore the Group is responsible for shipping services after the date at which control of the gold and silver passes to the customer. Under IAS 18, these shipping services were not considered to be part of the revenue transaction and thus the Group disclosed them as selling expenses. However, under IFRS 15 the group reclassified the portion of those selling expenses relating to transport of gold and silver from the Group's production plants to the ports and to the customers, and reclassify those costs to cost of sales. . The shipping services reclassified for the period ending 31 December 2018 amounted to US$6,102,000. The Group assessed the amount of costs related to shipping services which are considered a separate performance obligation under IFRS 15 and therefore, a portion of the revenue currently recognised when the tittle has passed to the customer will need to be deferred and recognised as the shipping services are subsequently provided. Under IFRS 15 the costs related to shipping services are considered a separate performance obligation and therefore they should be deferred and recognised as the shipping services are subsequently provided. Based on the Group's assessment, the shipping services being provided at the end of the reporting period are immaterial and therefore these have not been deferred. The total shipping services recognised during the year as a separate performance obligation under IFRS 15 amount to $5,485,000 and have been disclosed in note 4.

-- IFRS 9 Financial Instruments, applicable for annual periods beginning on or after 1 January 2018.

IFRS 9 Financial Instruments addresses the classification, measurement and derecognition of financial assets and financial liabilities, introduces new rules for hedge accounting and a new impairment model for financial assets.

Based on the assessment performed, the new guidance has the following impacts on the classification and measurement of its financial instruments:

- Classification and measurement of the embedded derivatives arising from sales: The financial assets and liabilities arising from the revaluation provisional priced contracts are currently disclosed separately in the balance sheet as part of "other financial assets/liabilities". Under IFRS 9, the embedded derivative will no longer be separated from the host contract and therefore the revaluation of provisionally priced contracts is disclosed within the receivable of the host contract in "trade and other receivables".

- Financial assets at fair value through Other Comprehensive Income ('OCI'): The equity instruments that were classified as available-for-sale financial assets satisfy the conditions for classification as at fair value through other comprehensive income (FVOCI) and therefore there is no impact in classification. Gains and losses accumulated in other comprehensive income are not recycled to the income statement. Furthermore, under IFRS 9 there is no exception to carry investments in entities at costs less any recognised impairment and therefore, fair value will need to be calculated. There are no other significant changes to the accounting treatment of these assets.

- Impairment: The new impairment model requires the recognition of impairment provisions based on expected credit losses (ECL) rather than only incurred credit losses as is the case under IAS 39. The Group applies the simplified approach and records lifetime expected losses on all trade receivables. However, given the short term nature of the Groups receivables, there is not a significant impact in the financial statements.

- Disclosures: The standard introduces expanded disclosure requirements and changes in presentation included in these report.

The Group also assessed other changes introduced by IFRS 9 that have no impacts in the financial statements as explained below:

- There is no impact on the accounting for financial liabilities, as the new requirements of IFRS 9 only affect the accounting for financial liabilities that are designated at fair value through profit or loss and the group does not have any such liabilities.

- The Group does not currently apply hedge accounting and therefore there are no impacts in the financial statements.

- No impacts in relation to derecognition of financial instruments as the same rules have been transferred from IAS 39 Financial Instruments: Recognition and Measurement.

-- IFRS 2 Classification and Measurement of Share-based Payment Transactions - Amendments to IFRS 2, applicable for annual periods beginning on or after 1 January 2018.

The amendments are related to the classification and measurement of share-based payment transactions and it does not require to restate prior periods. The adoption of these amendments does not have a significant impact on the Group's financial position or performance.

Standards, interpretations and amendments to existing standards that are not yet effective and have not been previously adopted by the Group

Certain new standards, amendments and interpretations to existing standards have been published and are mandatory for the Group's accounting periods beginning on or after 1 January 2019 or later periods but which the Group has not previously adopted. Those that are applicable to the Group are as follows:

   --          IFRS 16 Leases, applicable for annual periods beginning on or after 1 January 2019. 

IFRS 16 specifies how an IFRS reporter will recognise, measure, present and disclose leases. The standard provides a single lessee accounting model, including the exemptions to recognise assets and liabilities for all leases unless the lease term is 12 months or less or when the underlying asset has a low value. Lease costs will be recognised in the income statement over the lease term in the form of depreciation on the right of use asset and finance charges representing the unwinding of the discount on the lease liability. Lessors continue to classify leases as operating or finance, with IFRS 16's approach to lessor accounting substantially unchanged from its predecessor, IAS 17. The Group has progressed its implementation project, focusing on a review of contracts, aggregation of data to support the evaluation of the accounting impacts of applying the new standard and assessment of the need for changes to systems and processes. Accordingly, the Group has decided to apply the exemption of short term leases (12 months or above) and determined that only contracts with a value of US$1,000,000 or more will have a significant effect on the Group's Financial Statements, increasing the assets and liabilities and changing the classification and timing of expenses, so contracts with a value less than US$1,000,000 are not to be considered. As at 31 December 2018, the Group has identified one contract applicable for a total value of US$5,413,000, then since 1 January 2019 the Group will recognise a right of use asset by contract and its corresponding liability and finance expenses.

-- IFRIC 23 Uncertainty over income tax treatments, applicable for annual periods beginning on or after 1 January 2019.

IFRIC 23 clarifies the accounting for uncertainties in income taxes. This interpretation is to be applied to the determination of taxable profit (tax loss), tax bases, unused tax losses, unused tax credits and tax rates, when there is uncertainty over income tax treatments under IAS 12. The Group will adopt. The Interpretation specifically addresses the following:

   o    Whether an entity considers uncertain tax treatments separately; 

o The assumptions an entity makes about the examination of tax treatments by taxation authorities;

o How an entity determines taxable profit (tax loss), tax bases, unused tax losses, unused tax credits and tax rates; and

   o    How an entity considers changes in facts and circumstances 

The interpretation is effective for annual reporting periods beginning on or after 1 January 2019, but certain transition reliefs are available. The Group will apply interpretation from its effective date, however we do not expect significant impacts on the financial statements on the implementation as the Group's current treatment is in line with the requirements of the interpretation.

The Group is analysing the effect of the standards and plans to adopt the new standards on the required effective date.

3 Segment reporting

The Group's activities are principally related to mining operations which involve the exploration, production and sale of gold and silver. Products are subject to the same risks and returns and are sold through similar distribution channels. The Group undertakes a number of activities solely to support mining operations including power generation and services. Transfer prices between segments are set on an arm's length basis in a manner similar to that used for third parties. Segment revenue, segment expense and segment results include transfers between segments at market prices. Those transfers are eliminated on consolidation.

For internal reporting purposes, management takes decisions and assesses the performance of the Group through consideration of the following reporting segments:

-- Operating units - San Jose, which generates revenue from the sale of gold, silver (dore and concentrate).

-- Operating unit - Arcata and Pallancata, which generate revenue from the sale of gold and silver (concentrate).

-- Operating unit - Inmaculada, which generates revenue from the sale of gold and silver (dore).

-- Exploration, which explores and evaluates areas of interest in brownfield and greenfield sites with the aim of extending the life--of--mine

of existing operations and to assess the feasibility of new mines. The exploration segment includes costs charged to the profit and loss

and capitalised as assets.

-- Other - includes the profit or loss generated by Empresa de Transmisión Aymaraes S.A.C. (a power transmission company that absorbed Empresa de Transmisión Callalli S.A.C. on 1 June 2016).

The Group's administration, financing, other activities (including other income and expense), and income taxes are managed at a corporate

level and are not allocated to operating segments.

Segment information is consistent with the accounting policies adopted by the Group. Management evaluates the financial information

based on International Financial Reporting Standards (IFRS) as adopted for use in the European Union.

The Group measures the performance of its operating units by the segment profit or loss that comprises gross profit, selling expenses

and exploration expenses.

Segment assets include items that could be allocated directly to the segment.

1 Mine-site exploration is performed with the purpose of identifying potential minerals within an existing mine-site, with the goal of maintaining or extending the mine's life.

2 Prospects expenditure relates to detailed geological evaluations in order to determine zones which have mineralisation potential that is economically viable

for exploration. Exploration expenses are generally incurred in the following areas: mapping, sampling, geophysics, identification of local targets and reconnaissance drilling.

3 Generative expenditure is early stage exploration expenditure related to the basic evaluation of the region to identify prospects areas that have the geological conditions necessary to contain mineral deposits. Related activities include regional and field reconnaissance, satellite images, compilation of public information and identification of exploration targets.

The increase in exploration expenses is mainly explained by the work performed at the Arcata mine unit trying to identify new possible ore targets and the signature of new agreements related to projects in United States, Chile and Peru.

The Group determines the cash flows which relate to the exploration activities of the companies engaged only in exploration. Exploration activities incurred by Group operating companies are not included since it is not practicable to separate the liabilities related to the exploration activities of these companies from their operating liabilities.

Cash outflows on exploration activities were US$10,498,000 in 2018 (2017: US$2,600,000).

1 On 29 December 2017, the Argentinian government enacted a tax reform. The main change is the reduction in the statutory income tax rate, from its current level of 35% to 30% with effect from 1 January 2018 and to 25% with effect from 1 January 2020.

The weighted average statutory income tax rate was 32.2% for 2018 and 31.9% for 2017. This is calculated as the average of the statutory tax rates applicable in the countries in which the Group operates, weighted by the profit/(loss) before tax of the Group companies in their respective countries as included in the consolidated financial statements.

The change in the weighted average statutory income tax rate is due to a change in the weighting of profit/(loss) before tax in the various jurisdictions in which the Group operates.

The tax related to items charged or credited to equity is as follows:

1 Argentina benefits from a special investment regime that allows for a super (double) deduction in calculating its taxable profits for all costs relating to prospecting, exploration and metallurgical analysis, pilot plants and other expenses incurred in the preparation of feasibility studies for mining projects.

2 Includes the income tax credit on mine closure provision of US$412,000 (2017: US$3,010,000), the tax charge related to the Inmaculada mine unit depreciation of US$1,631,000 (2017: US$3,246,000), the effect of not recognised tax losses of US$1,696,000 (2017: US$949,000) and the unrecognised deferred tax on San Felipe of US$nil (2017: credit of US$2,509,000).

3 The Argentinian government approved a reduction in the statutory income tax rate, from 35% to 30% with effect from 1 January 2018 and 25% with effect from 1 January 2020.

   4   Corresponds to the impact of a mining royalty and special mining tax in Peru (note 29). 

5 The foreign exchange effect is composed of US$9,311,000 (2017: US$2,893,000) from Argentina and US$4,760,000 (2017: credit of US$3,936,000) from Peru. This mainly corresponds to the foreign exchange effect of converting tax bases and monetary items from local currency to the corresponding functional currency. The main contributor of the foreign exchange effect on the tax charge in 2018 is the devaluation of the Argentinian peso.

14 Basic and diluted earnings per share

Earnings per share ('EPS') is calculated by dividing profit for the year attributable to equity shareholders of the Company by the weighted average number of ordinary shares issued during the year.

The Company has dilutive potential ordinary shares.

As at 31 December 2018 and 2017, EPS has been calculated as follows:

1 Within mining properties and development costs there is a balance at 31 December 2018 related to Crespo project (US$26,855,000) that is not currently being depreciated.

2 Transfers and other movements include US$2,379,000 that was transferred from evaluation and exploration assets (note 16).

3 Includes borrowing costs capitalised in property, plant and equipment amounting to US$239,000. The capitalisation rate used was 2.88%.

In 2018, management determined there were triggers of impairment in the San Jose mine unit due to the devaluation of the US$, inflation and the new export tax approved in Argentina since September 2018. Impairment test result did not show a difference versus the carrying value given that the level of devaluation offset inflation and the new export tax. Therefore, no impairment was recognised.

In addition, during 2018, management evaluated the carrying value of the San Felipe Project, not recognising any impairment in the period (refer to note 16).

No indicators of impairment or reversal of impairment were identified in the other CGUs, which includes other exploration projects.

In 2017, management determined there were triggers of impairment in the Arcata mine unit due to difficulties in replacing production with incremental resources and to convert resources into reserves, and there was a significant decrease in production during the year. An impairment test was carried out resulting in an impairment charge of US$43,009,000 (US$39,905,000 in property, plant and equipment and US$3,104,000 and evaluation and exploration assets).

Also in 2017, in the case of the Pallancata mine unit, there was an increase in terms of tonnage, grades, and resources and reserves due to the Pablo vein. An impairment test was carried out resulting in an impairment reversal of US$31,892,000 (US$31,509,000 in property, plant and equipment and US$383,000 and evaluation and exploration assets).

Finally, in 2017, management evaluated the carrying value of the San Felipe Project, recognising an impairment reversal of US$8,364,000 (all in evaluation and exploration assets) (refer to notes 10 and 16).

The recoverable values of the San Jose, Arcata and Pallancata CGUs were determined using a fair value less costs of disposal (FVLCD) methodology. FVLCD was determined using a combination of level 2 and level 3 inputs, which result in fair value measurements categorised in its entirety as level 3 in the fair value hierarchy, to construct a discounted cash flow model to estimate the amount that would be paid by a willing third party in an arm's length transaction.

In assessing the recoverable value of the San Felipe CGU, given the early stage of the project, the Group applied a value in-situ methodology which applies a realisable 'enterprise value' to unprocessed mineral resources. The enterprise value used is based on observable external market information. Together with the US$31,396,000 (2017: US$29,396,000) recognised as a deferred income (refer to note 22) that will be realised once the option is exercised or terminated; the total recoverable value of the project under a VIU approach amounts to US$37,081,000 (2017: US$37,081,000).

The key assumptions on which management has based its determination of FVLCD and the associated recoverable values calculated are gold and silver prices, production costs, reserves and resources, the discount rate and the value per in-situ regarding the San Felipe project. Gold and silver prices used, discount rate applied and value per in-situ per zinc equivalent tonne are presented below.

Sensitivity analysis

Other than as disclosed below, management believes that no reasonably possible change in any of the key assumptions above would cause the carrying value of any of its cash generating units to exceed its recoverable amount.

The estimated recoverable amounts of the following of the Group's CGUs are equal to, or not materially greater than, their carrying values.

A change in any of the key assumptions would have the following impact in the San Jose mine unit:

 
                                                         US$000 
===================================================   ========= 
 Prices (decrease by 10%)                              (85,590) 
----------------------------------------------------  --------- 
 Post tax discount rate (increase by 3%)                (9,937) 
----------------------------------------------------  --------- 
 Production costs (increase by 10%)                    (56,551) 
----------------------------------------------------  --------- 
 Inflation (increase by 10%)                           (19,425) 
----------------------------------------------------  --------- 
 Devaluation of Argentinian peso (increase by 10%)       20,765 
====================================================  ========= 
 

With respect to the impairment assessment performed at the San Felipe CGU, a decrease of 10% in the value in-situ per tonne would result in a reversal of impairment of US$504,000, whilst an increase of 10% would result in a reversal of previously recognised impairment of US$647,000.

1 The transmission line is amortised using the units of production method. At 31 December 2018 the remaining amortisation period is approximately 7 years (2017: 8 years).

2 Corresponds to the acquisition of water permits of Andina Minerals Group ("Andina"). These permits have an indefinite life according to Chilean law. To determine the fair value less costs of disposal of the Volcan cash-generating unit, which includes the water permits held by the Group, the Group used the value-in-situ methodology. This methodology applies a realisable 'enterprise value' to unprocessed mineral resources which was US$6.70 per gold equivalent ounce of resources at 31 December 2018 (2017: US$7.10). The risk adjusted enterprise value figure has been determined using a combination of level 2 and level 3 inputs, which result in a fair value measurement categorised in its entirety as level 3 in the fair value hierarchy, to estimate the amount that would be paid by a willing third party in an arm's length transaction, taking into account the water restrictions imposed by the Chilean government.

3 Legal rights correspond to expenditures required to give the Group the right to use a property for the surface exploration work, development and production.

At 31 December 2018 the remaining amortisation period is from 5 to 20 years (2017: 10 to 20 years).

4 The amortisation for the period is included in cost of sales and administrative expenses in the income statement.

The carrying amount of the Volcan CGU, which includes the water permits, is reviewed annually to determine whether it is in excess of its recoverable amount. No impairments were recognised in 2018 and 2017.

Sensitivity analysis

Other than as disclosed below, management believes that no reasonably possible change in any of the key assumptions above would cause the carrying value exceed its recoverable amount.

The estimated recoverable amount is not materially greater than its carrying value. A change in the value in situ assumption could cause an impairment loss or reversal of impairment to be recognised as follows:

The fair values of trade and other receivables approximate their book value.

1 Relates to export benefits through the Patagonian port and silver refunds in Minera Santa Cruz, discounted over 24 months (2017: 19 months) at a rate of 9.98% (2017: 5.40%) for dollars denominated amounts and 57.00% (2017: 29.60%) for Argentinian pesos. The loss on the unwinding of the discount is recognised within finance costs (2017: gain on discount is recognised within finance income).

2 Mainly corresponds to account receivables from contractors for the sale of supplies of US$6,111,000 (2017: US$4,773,000), and other tax claims of US3,227,000 (2017: US$3,903,000).

3 Includes the provision for impairment of trade receivable from customers in Peru of US$1,554,000 (2017: US$1,080,000), the impairment of deposits in Kaupthing, Singer and Friedlander of US$195,000 (2017: US$208,000), the impairment of the account receivable from a third party of US$3,233,000 (2017: US$2,501,000) and other receivables of US$1,1015,000 (2017: US$805,000).

Finished goods include ounces of gold and silver, dore and concentrate.

Products in process include stockpile and precipitates.

The Group either sells dore bars as a finished product or if it is commercially advantageous to do so, delivers the bars for refining into gold and silver ounces which are then sold. In the latter scenario, the dore bars are classified as products in process. At 31 December 2018 and 2017 the Group had no dore on hand included in products in process.

Concentrate is sold to smelters, but in addition could be used as a product in process to produce dore.

As part of the Group's short-term financing policies, it acquires pre-shipment loans which are guaranteed by the sales contracts.

The amount of expense recognised in profit and loss related to the consumption of inventory of supplies, spare parts and raw materials is US$111,485,000 (2017: US$104,689,000).

Movements in the provision for obsolescence comprise an increase in the provision of US$384,000 (2017: US$542,000) and the reversal of US$Nil relating to the sale of supplies and spare parts, that had been provided for (2017: US$2,997,000).

1 On 3 August 2011, the Group entered into an agreement with Impulsora Minera Santa Cruz ("IMSC") whereby IMSC acquired the right to explore the San Felipe properties and an option to purchase the related concessions. Under the terms of this agreement the Group has received US$31,396,000 as non-refundable payments at 31 December 2018 (2017: US$29,396,000). These payments will reduce the total consideration that IMSC will be required to pay upon exercise of the option and constitute an advance of the final purchase price, rather than an option premium and, as such, they were recorded as deferred income.

On 30 November 2016, IMSC renegotiated the terms of the agreement, extending the validity of the agreement to 1 December 2017. As a result of this extension, on 9 March 2017 the Group received in payment 13,415,000 ordinary shares of Santa Cruz Silver Mining ("SCSM") quoted in the Toronto Stock Exchange, at the unit price of CAD 0.28 amounting to CAD 3,756,000 equivalent to US$2,780,000. The amount received included valued added taxes of US$384,000 and part consideration of US$2,396,000 recognised as deferred income.

On 28 February 2017, the Group signed a new option agreement with IMSC for the San Felipe properties for a total consideration of US$10,000,000. An initial payment of US$2,000,000 was received in cash on 7 March 2017.

In March 2017, IMSC entered into an agreement with Americas Silver Corporation ('ASC') to assign 100% of its interest in the San Felipe Project.

During 2018 the Group collected US$2,000,000 (January 2018:US$500,000, April 2018: US$500,000 and July 2018: US$1,000,000).

On 15 December 2018, the option to sell the San Felipe property to ASC was extended to 31 December 2020.

2 On 25 April 2017 the Group signed a five-year option agreement with Minas Argentinas S.A. ("MASA") giving MASA the right to explore and the option to purchase the Mosquito property, located in Argentina. The Group has received in cash US$2,000,000, recognising US$970,000 as deferred income at 31 December 2018.

1 The provision represents the discounted values of the estimated cost to decommission and rehabilitate the mines at the expected date of closure of each of the mines. The present value of the provision has been calculated using a real pre-tax annual discount rate, based on a US Treasury bond of an appropriate tenure adjusted for the impact of quantitative easing as at 31 December 2018 and 2017 respectively, and the cash flows have been adjusted to reflect the risk attached to these cash flows. Uncertainties on the timing for use of this provision include changes in the future that could impact the time of closing the mines, as new resources and reserves are discovered. The discount rate used was 0.30% (2017: 0.14%). Expected cash flows will be over a period from one to nineteen years.

2 Corresponds to the provision related to awards granted under the Long Term Incentive Plan ('LTIP') to designated personnel of the Group. Includes the following benefits: (i) 2018 awards, granted in May 2018, payable in May 2021, as 50% in cash, (ii) 2017 awards, granted in March 2017, payable in full on vesting in March 2020. Only employees who remain in the Group's employment on the vesting date will be entitled to vested awards, subject to exceptions approved by the Remuneration Committee of the Board. There are two parts to the performance conditions attached to LTIP awards: 70% is subject to the Company's TSR ranking relative to a tailored peer group of mining companies, and 30% is subject to the Company's TSR ranking relative to the constituents of the FTSE 350 mining index. The liability for the LTIP paid in cash is measured, initially and at the end of each reporting period until settled, at the fair value of the awards, by applying the Monte Carlo pricing model, taking into account the terms and conditions on which the awards were granted, and the extent to which the employees have rendered services to date. Changes to the provision of US$3,386,000 (2017: US$8,702,000) have been recorded as administrative expenses US$3,203,000 (2017: US$8,215,000) and exploration expenses US$183,000 (2017: US$487,000).

The following tables list the inputs to the Monte Carlo model used for the LTIPs as at 31 December 2017 and 2018, respectively:

29 Mining royalties

Peru

In accordance with Peruvian legislation, owners of mining concessions must pay a mining royalty for the exploitation of metallic and non--metallic resources. Mining royalties have been calculated with rates ranging from 1% to 3% of the value of mineral concentrate

or equivalent sold, based on quoted market prices.

In October 2011 changes came into effect for mining companies, with the following features:

a) Introduction of a Special Mining Tax ('SMT'), levied on mining companies at the stage of exploiting mineral resources. The

additional tax is calculated by applying a progressive scale of rates ranging from 2% to 8.4%, of the quarterly operating profit.

b) Modification of the mining royalty calculation, which consists of applying a progressive scale of rates ranging from 1% to 12%,

of the quarterly operating profit. The former royalty was calculated on the basis of monthly sales value of mineral concentrates.

The SMT and modified mining royalty are accounted for as an income tax in accordance with IAS 12 "Income Taxes".

c) For companies that have mining projects benefiting from tax stability regimes, mining royalties are calculated and recorded as they were previously, applying an additional new special charge on mining that is calculated using progressive scale rates, ranging from 4% to 13.12% of quarterly operating profit.

d) In the case of the Arcata mine unit, the company left the tax stability agreement, but has maintained the agreement for the mining royalties, such that the Arcata unit, is liable for the new SMT but the mining royalties remain payable at the same rate as they were, before the modification in 2011.

As at 31 December 2018, the amount payable as under the former mining royalty (for the Arcata mining unit), the new mining royalty (for the Ares, Pallancata and Inmaculada mining units), and the SMT amounted to US$39,000 (2017: US$108,000), US$975,000 (2017: US$1,133,000), and US$279,000 (2017: US$492,000) respectively. The former mining royalty is recorded as 'Trade and other payables', and the new mining royalty and SMT as 'Income tax payable' in the Statement of Financial Position. The amount recorded in the income statement was US$561,000 (2017: US$885,000) representing the former mining royalty, classified as cost of sales, US$4,494,000 (2017: US$4,201,000) of new mining royalty and US$2,727,000 (2017: US$2,229,000) of SMT, both classified as income tax.

Argentina

In accordance with Argentinian legislation, Provinces (being the legal owners of the mineral resources) are entitled to collect royalties from mine operators. For San Jose, the mining royalty applicable to dore and concentrate is 3% of the pit-head value. As at 31 December 2018, the amount payable as mining royalties amounted to US$467,000 (2017: US$576,000). The amount recorded in the income statement as cost of sales was US$5,296,000 (2017: US$5,792,000).

30 Subsequent events

a) The Group announced its intention to suspend operations at the Arcata mine, in south west Peru, and place it on care and maintenance. It is anticipated that full care and maintenance will be in effect by the second quarter of 2019. An exploration programme and permitting work are expected to continue along with a regular review of the market conditions for potential restart of operations in the future.

RESERVES AND RESOURCES

Ore reserves and mineral resources estimates

Hochschild Mining plc reports its mineral resources and reserves estimates in accordance with the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves 2012 edition ("the JORC Code"). This establishes minimum standards, recommendations and guidelines for the public reporting of exploration results and mineral resources and reserves estimates. In doing so it emphasises the importance of principles of transparency, materiality and confidence. The information on ore reserves and mineral resources on pages 43 to 45 were prepared by or under the supervision of Competent Persons (as defined in the JORC Code). Competent Persons are required to have sufficient relevant experience and understanding of the style of mineralisation, types of deposits and mining methods in the area of activity for which they are qualified as a Competent Person under the JORC Code. The Competent Person must sign off their respective estimates of the original mineral resource and ore reserve statements for the various operations and consent to the inclusion of that information in this report, as well as the form and context in which it appears.

Hochschild Mining plc employs its own Competent Person who has audited all the estimates set out in this report. Hochschild Mining Group companies are subject to a comprehensive programme of audits which aim to provide assurance in respect of ore reserve and mineral resource estimates. These audits are conducted by Competent Persons provided by independent consultants. The frequency and depth of an audit depends on the risks and/or uncertainties associated with that particular ore reserve and mineral resource, the overall value thereof and the time that has lapsed since the previous independent third-party audit.

The JORC Code requires the use of reasonable economic assumptions. These include long-term commodity price forecasts (which, in the Group's case, are prepared by ex-house specialists largely using estimates of future supply and demand and long-term economic outlooks).

Ore reserve estimates are dynamic and are influenced by changing economic conditions, technical issues, environmental regulations and any other relevant new information and therefore these can vary from year-to-year. Mineral resource estimates can also change and tend to be influenced mostly by new information pertaining to the understanding of the deposit and secondly the conversion to ore reserves.

The estimates of ore reserves and mineral resources are shown as at 31 December 2018, unless otherwise stated. Mineral resources that are reported include those mineral resources that have been modified to produce ore reserves. All tonnage and grade information has been rounded to reflect the relative uncertainty in the estimates; there may therefore be small differences. The prices used for the reserves calculation were: Au Price: US$1,150 per ounce and Ag Price: US$15.0 per ounce.
