Danny Callow, CEO of African Gold Group, commented:
“Over the past two years we have worked tirelessly to demonstrate that the Kobada Gold Project has the potential to be one of the largest new gold projects in West Africa. Since the implementation of management changes in August 2019, and with new drilling campaigns totalling around 18,000 metres, we have managed to increase our reserve base by 144% (66% increase over the 2020 DFS).
With our updated 2021 DFS we have shown that Kobada has the potential to produce over 1.2 mln oz of gold over a 16 year mine life while delivering solid economics with post-tax NPV5% of US$355 million and an IRR of 38%.
Kobada is a predominantly free-dig operation, requires limited blasting, and processing of ore will be through a very simple and proven gravity plus CIL plant with recoveries over 95% in both oxides and sulphides. The inclusion of sulphides in this updated DFS, which are free milling and easy to process, opens significant future opportunities within the sulphide resource as well as continuing growth possibilities in the oxides. We are confident in the capital estimates as compared to recent similar completed projects in the region, and these costs remain very competitive for a project of this size. The potential to produce significant free cash flows after tax and low capital expenditure highlights very attractive economics of our Kobada project.
Based upon our detailed understanding and integrity of the current resource, on only 4 km of our 55 km of identified shear zones we believe that there continues to be significant potential to increase our 3.1 million ounce total resource substantially further. Kobada is now positioned as a great construction opportunity, in a prolific gold-producing area of West Africa”

Kobada Gold Project Overview
The Kobada Gold Project is located in southern Mali, approximately 125 km in a straight-line south-southwest of the capital city Bamako and is situated adjacent to the Niger River and the international border with Guinea.
The Kobada Gold Project is based on one mining exploitation permit (Kobada) of 136 km2 and two exploration permits (Faraba and Kobada Est) of 77 km2 and 45 km2, which are wholly owned by AGG Mali SARL, the local Malian company, a 100% owned subsidiary of African Gold Group.
AGG has completed 114,357 metres of diamond, reverse circulation, air core and auger drilling between 2005 and 2012. In 2015, AGG completed a further 1,398 metres of diamond core drilling over 13 diamond drill holes. The current AGG exploration re-commenced in August 2019 and an additional 18,000 metres of exploration drilling has been completed.
Gold mineralization is present in the laterite, saprolite, and quartz veins that comprise the project, and in the sulphidic hard rock underneath. There are also placer style deposits in the region.
2020 Drilling Campaign
The 2020 drilling campaign, running from September 2020 until January 2021, consisted of 43 drillholes totalling 6,364 m. Of these, 4 drillholes (522 m) were drilled at the Gosso target and the remaining 39 drillholes (5,842 m) were drilled in the “gap” area and northern extents of the northern domain of the Kobada main shear. The drillholes at the Gosso target were all completed using diamond drilling while the drilling at Kobada was a combination of diamond drilling (8 holes @ 1,258 m) and RC drilling (21 holes @ 2,890 m) with selected RC drillholes being completed with diamond tail (10 holes @ 1,221 m RC and 473 m diamond) to drill into the sulphides.
The main focus of the drilling was to confirm and improve the confidence in the geological model to enable additional mineral resource conversion of the oxides to the measured and indicated resource categories. The drilling was also used to test and confirm the depth extension of the saprolitic (soft) material, the transition zone and the sulphides at depth.
For the Kobada main shear drilling, 34 drillholes intersected the mineralised zones and had an average accumulated mineralisation width of 29 m @ 1.22 g/t. The drilling campaign has significantly contributed to the increase in the indicated resource in the northern domain of the Kobada main shear, and also highlighted areas of deeper weathering with oxide material extending further down to a depth of approximately 160 m in places, approximately 60 to 80 m deeper than originally anticipated.
The drillholes at Gosso target confirmed the mineralisation observed in the historical drillholes with the 4 drillholes having an average accumulated mineralisation width of 12 m @ 1.11 g/t.

Status of Exploration
Upside potential remains in the short term at the Kobada Main Shear to upgrade some additional inferred mineral resources to the indicated category. In addition to this, the Project has significant upside potential in the 55 km strike length of potential mineralised shear zones. These shear zones are shown in Figure 3. Of these, the Gosso target is considered the most prospective due to its similar mineralisation profile to Kobada Main Shear and close proximity to the processing plant. To date, only limited drilling has been completed (21 drillholes) at Gosso, with exciting drill results such as 1.15 g/t Au over 12.5 m, including 7.19 g/t Au over 1.3 m. In addition, initial field investigations by the AGG geologists, in early 2021, have highlighted significant upside potential at the Kobada Est targets where artisanal mining has exposed mineralised structural features.
The Faraba exploration permit, renewed in August 2021 for a further 3 years, shows potential continuation of the Main Shear zone in a north-north-east direction opening up further exploration potential.

Mine Planning
DRA Americas undertook the mine planning process, based on the measured and indicated mineral resources delineated to date at the Kobada Gold Project. Pit optimizations were undertaken using the following parameters:
| Gold price | US$1,610/oz (base case) | |
| Mining Costs | US$ 2.5/t to US$3.0/t | |
| Processing Costs | US$ 9.41/t to US$15.08/t | |
| Mining dilution | 5% | |
| Mining recovery | 95% | |
| Pit slopes | 40° overall slope angle | |
| Metallurgical recovery | Laterite Oxide ore | 96.5% |
| Saprolite Oxide ore | 96.5% | |
| Transitional ore | 90.5% | |
| Sulphide ore | 95.4% | |
Table 2: Pit Optimization Parameters
The Kobada Gold Project deposit is planned to be mined utilising standard open-pit mining methods using articulated trucks and a hydraulic loader (hydraulic shovel or excavator). Approximately 66% of the raw material to be mined is contained in the saprolite and laterite ores, and the vast majority will be free digging with no blasting required.
The final pit design for the Kobada Gold Project deposit is approximately 4.3 km long, with a maximum width of 500 m and a maximum depth of 180 m as shown in Figure 4.
Figure 4: Kobada Final Pit Design is available at https://www.globenewswire.com/NewsRoom/AttachmentNg/bb003886-2e9a-4f12-a67e-ac16f0177eb0
The open pit mining operation will last approximately eleven years, during which the lower-grade material will be stockpiled on a pad close to the primary crusher location.
The mine plan targets higher grade oxide ore zones at the early phase of the project to feed into the process plant in order to produce an average of 100,000 oz per annum for the first 10 years, and thereafter lower production output as the grade drops and stockpiles are treated. Further targeted drilling will aim to improve the output from Years 11 to 16 by drilling the inferred resources in and around the existing pit shell. Management remains confident that further drilling will yield additional measured and indicated ounces to convert into additional reserves.
Over the life of the Project, 45 Mt of ore will be mined and delivered to the processing facility, and a total of 158 Mt of material will be mined and placed on the waste dumps, representing a life of mine stripping ratio of 3.5:1.
The mining operations will be undertaken by a specialized contractor selected by the Company. This contractor will be responsible for the management and maintenance of its own mining fleet and operators, while AGG will oversee the mine planning and geological grade control aspects of the operation. There remains an option for owner mining through leasing of mining equipment, and these options will be looked at as part of the detailed engineering design process.
Mineral Reserve
This updated mineral reserve and resource estimate at the Kobada Gold Project, as summarized in Table 1 and Table 3, was prepared in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum “CIM” (2014) Definition Standards incorporated by reference in NI 43-101 and is the result of 17,355 meters (108 drill holes) of drilling completed by the Company between H2-2019 and H1-2021 in addition to the historical drilling completed in previous years.
| Reserve Classification | Tonnage 1(Mt) | Grade(g/t) | Contained Gold(kg) | Contained Gold(oz) |
| Proven 2 | 20.26 | 0.91 | 14,963 | 527,800 |
| Probable 2 | 24.77 | 0.87 | 20,545 | 724,700 |

Mine Schedule
The mining schedule has focused on maximising gold production at an average annualized rate of 100,000 oz per annum, but also targeting the lower capital-intensive oxides initially before mining and processing the sulphides. The updated optimised mining schedule is indicated in Figure 5.
Figure 5: Gold Production over LOM is available at https://www.globenewswire.com/NewsRoom/AttachmentNg/808904cf-69d6-4f57-b8f3-9c90abc0d57e
Processing
In 2019/2020 comprehensive metallurgical tests inclusive of variability were conducted on saprolite/laterite ore types to establish the optimum processing route. This test work was conducted by Maelgywn Mineral Services (“MMS”) in South Africa under SENET’s supervision. Results from this test work indicated that the saprolite/laterite ore:
In 2021, further comprehensive metallurgical tests were conducted on the sulphides which previously were not tested. The test work involved investigating the suitability of the processing route using the flowsheet developed for saprolite/laterite and conducting variability tests. Results obtained for sulphides showed the following:
The proposed process plant design is based on a proven and established gravity/carbon-in-leach (“CIL”) technology, which consists of crushing, milling, and gravity recovery of free gold, followed by leaching/adsorption of gravity tailings, elution and gold smelting, and tailings disposal. Services to the process plant will include reagent mixing, storage and distribution, water, and air services. The plant will treat 3 Mtpa of saprolite/laterite/sulphide ore to produce an average of 100,000 oz per annum. The crushing and milling circuits will be constructed in two phases: the first phase will be to treat oxide ore only, followed by a second phase later in the life of mine to treat sulphides and/or a blend of sulphides and oxides.
When treating oxide ore, only the primary crushing stage will be in use while three crushing stages will be required when treating the sulphide ore. When treating saprolite/laterite, the milling circuit will utilize a single-stage ball mill while an additional secondary mill will be added in the later part of the mine life to treat sulphides. The process plant was designed on the following principles:
Figure 6: Process Plant Flowsheet is available at https://www.globenewswire.com/NewsRoom/AttachmentNg/9f1cbea8-2686-49eb-9ff7-9b9efcca93c4
Power
Due to the relatively poor electrical infrastructure in the region, tying into the national grid is not a feasible solution. SENET therefore undertook studies to investigate the potential for a standalone 21 MW power plant for the 2021 DFS.
An in-depth study found that the development of a hybrid solar photovoltaic (“PV”), battery energy storage system (“BESS”) and thermal power plant funded by an Independent Power Producer (“IPP”) to be the best option. This will reduce the CAPEX required, lowering the initial investment as the equipment is owned by the IPP an in addition lowers the operational risk with a very competitive power purchase rate.
The inclusion of the hybrid solar PV along with the thermal power plant will not only save on energy cost but will also significantly reduce the mine’s environmental footprint in the region. The BESS will provide additional redundancy to the thermal plant and the system will be fully integrated with mining operations to ensure de-risked mining revenue generation.
This option will not only compliment AGG’s environmental strategy, but also presents an opportunity to reduce costs over the life of the Kobada Gold Project with improved reliability, cost-effectiveness, and redundancy to the total power requirements.
Highlights of the hybrid power system include significant emissions reduction compared to a conventional thermal plant with:
In addition to the environmental benefits, the significant fuel offset from the renewable energy component of the hybrid power system also de-risks the mine against fuel cost fluctuations.
Water
Raw water supply shall be achieved by a combination of raw water abstraction from the Niger River, and supplementary water supply from the eight open pit outer perimeter dewatering boreholes.
The water from these supplies shall be stored in a newly constructed 20,000 m3 raw water buffer dam located mid-way between the process plant and the Niger River. The process plant shall feature additional water storage facilities in terms of a 3,500 m3 raw water pond, a 10,600 m3 process water pond and a 4,500 m3 stormwater pond, respectively. Process water will be supplied by pumping supernatant water back from the TSF (as defined below).
Tailings Management
Epoch Resources (Pty) Ltd undertook the study design associated with the Tailings Storage Facility (“TSF”). The TSF is a HDPE lined, full containment valley type arrangement, with a LOM tailings storage requirement of 45.15 Mt at a deposition rate of 3 million dry tonnes per annum. The TSF infrastructure includes a slurry distribution pipeline, catchment paddocks, toe drain system, underdrainage system, curtain drain system, blanket drain system, solution collection pipeline, collection sumps and manholes, seepage cut-off trench, storm-water diversion trenches, emergency spillway, access roads and perimeter fence-line. A floating barge decants supernatant tailings slurry water and stormwater from the TSF back to the plant.
The TSF is to be constructed in phases over the LOM, utilizing open pit overburden material, in five downstream lifts following the construction of the initial starter embankment. The construction of Phase 1 has been split into Phase 1A in the first year of construction and Phase 1B in the second year of construction.
The full containment TSF design was adopted to take cognisance of the Global Tailings Standards and International Commission on Large Dams Tailings Dams Safety, the latter in draft status, both refer to robust TSF designs and potentially liquefiable tailings.
Accessibility and Transport/Logistics
SENET and Bolloré Logistics have undertaken surveys with detailed analysis of access routes to the Kobada project site for plant and equipment as well as ongoing production materials and consumables.
Based on the international routes and climate conditions, as well as size of cargo to be transported, either of the two major routes (i.e., from Abidjan or Dakar) will be used for the project to gain access to Bamako and the Kobada site. These routes are via:
From Bamako, transportation of materials and consumables to the site will be via the existing roads that link Bamako to Kobada village and the AGG camp comprising two distinct access routes. The preferred access route to the Kobada site is accessible in approximately 3–4 hour’s drive in a south-west direction from Bamako. After crossing the Niger River by barge there is approximately 8 km of untarred roads.
An alternate access route from Bamako to the Kobada mine site is via the RN7 (Bamako–Sikasso) for 80 km to the Sélingué road junction, thereafter an additional 60 km of paved road to Sélingué. Thereafter there is 52 km of laterite road to site. The construction of a new low-level bridge across the Fié River was addressed in the 2021 DFS and included in the capital expenditure.
Refining
There is no gold refining capability in Mali and thus doré produced at Kobada is to be refined outside the country, either in South Africa, Europe, or Dubai. Initial discussions have been held with refineries and although no agreements have been entered into, it is anticipated that the doré will be treated at the Rand Refinery in South Africa.
Environmental and Social Aspects
ABS Africa (Pty) Ltd (“ABS Africa”), together with Africa and Business Consulting Mali (“ABCOM”) and Insuco Limited (“Insuco”), have been appointed to undertake an Environmental and Social Impact Assessment (“ESIA”) for the Kobada Gold Project. The ESIA for the Kobada oxides feasibility study was completed during Q3 2021 and is currently awaiting approval. Delays to this were due to the global coronavirus pandemic during 2020 and part of 2021 and subsequent lockdowns which prevented community consultation taking place. These consultations were completed with overwhelming support for the Kobada Gold Project, and the final ESIA report has been submitted to the Malian Government. The assessment included the undertaking of a series of baseline studies, as well as the undertaking of an impact assessment and associated management plan, together with the required consultation and disclosure process.
Consultations with the relevant interested and affected parties indicated positive support for the project, while the ESIA has been accepted by the relevant authorities, with the permitting process being finalised.
An ESIA amendment only is required for the Kobada sulphide feasibility study. Various specialist studies have been completed as part of the sulphide feasibility study, and the ESIA amendment will be commissioned and once the oxide ESIA is approved an environmental permit updated.
Key Impacts
Key environmental and social impacts identified to date as part the ESIA process, are summarized as follows:
In order to achieve the appropriate environmental management standards and ensure that the findings of the environmental studies are implemented through practical measures, the recommendations from the ESIA have been used to compile an Environmental and Social Management Plan (“ESMP”). The role of the ESMP is to assist AGG in reducing potential impacts and risks and achieving its environmental objectives as well as fulfilling its commitment to the environment. The ESMP will be used to ensure compliance with environmental specifications, monitoring and management measures.
AGG will develop a series of Environmental Action Plans, in order to manage anticipated impacts as per the requirements of the IFC`s Sustainability Framework.
Capital Costs
The tables below summarize the estimated capital costs for the Kobada Gold Project as estimated by the independent consultants. These costs were in almost all cases built up from quotations and proposals from equipment and service providers.
The 2021 DFS costs currently utilize a contractor owned and operated mining fleet. The contractor mining option was found to be the preferred option for the project given the lower upfront capital cost.
The process plant will be developed in two phases; first phase will enable processing of saprolite/laterite ore for the first 7 years and additional crushing and milling capacity will be added to enable processing of sulphides and/or blend of oxides and sulphides.
The TSF will be developed in five distinct phases corresponding to “lifts” of the full containment dam wall. This has allowed for the costs to be allocated to the initial capital expenditure budget for the first phase and for sustaining capital for phases two and three.
All financial analysis for the life of mine includes the total design, construction and commissioning, production, sustaining and closure.

| Royalties | 1.40 | 52.46 |
| Total | 23.53 | 881.13 |
Table 6: Total Operating Cash Costs LOM
“OPEX has increased based upon significantly higher global costs of steel and fuel, which impacts power generation and mining costs specifically. Mining costs have increased by around $120/oz. The main contributor to this increase is the additional direct cost of mining waste and ore, accounting for approximately 50% of this increase. In addition, the impact of an extended life of mine and the contractor overheads associated with this, additional grade control, and drilling and blasting costs in more competent ore accounts for a further 25% increase. Finally, the impact of an increase in diesel cost used as an input parameter accounts for a further 25% increase. Despite these global increases the project delivers a very impressive post-tax free cash flow of US$550 million,” commented Danny Callow, CEO of African Gold Group.

Project Opportunities
The DFS has been completed based upon drilling of only 4 km of the main shear zone. Several other geologically similar shear zone structures totalling more than 55 km have been identified on the concession and these are yet to be drilled. There exists a significant opportunity to increase the size of the measured and indicated resource through targeted limited infill drilling in the inferred resources which would be an opportunity to increase mine life.
The Company, with the assistance of SENET, has advanced the engineering of the project past the level that is required for a DFS. A large part of the process plant is designed to a detailed engineering level, including earthworks and civil engineering drawings issued for construction. Ongoing schedule optimization may result in reducing the construction schedule and bringing first gold forward by a number of months.
Development Timetable
Construction of the process plant and associated infrastructure including Phase 1 of the TSF for the Kobada Gold Project is expected to take 19 months. First gold will be achieved where after the process plant will be ramped up to produce nameplate capacity within the following 2 production months. The mine is designed with ease of construction and operation as a priority. The simplified and compact process plant flowsheet minimizes the requirement for expensive and long lead process equipment, thereby substantially reducing the construction time.
“Utilising known technology to develop a robust plant flowsheet suitable for West African conditions, yet simple and flexible in design, has allowed us to fast-track the development of the engineering to a stage where much of the plant is now at detailed design level. This allows us to shorten the schedule significantly and save on engineering costs” says Danny Callow, Chief Executive Officer of AGG.
The Company also intends to outsource key specialised components of the plant from the best-in-class providers, including a state-of-the-art hybrid, solar PV, thermal and BESS, fuel storage and supply, and the mining and TSF contract.
