African Gold Group Confirms Both Oxides and Sulphides To Be Incorporated Into Updated Feasibility Study

July 15, 2021, Toronto, Ontario – African Gold Group, Inc. (TSX-V: AGG) (“AGG” or the “Company”) is pleased to announce final metallurgical test results from its comprehensive sulphide testwork programme. Results of the testwork programme will be incorporated into an updated definitive feasibility study (DFS). The final phase of the testwork programme was to undertake variability testing to determine the optimal process route of the ore across the extent of the ore body. The Company is continuing its work on updating mineral resource estimates (MRE) and an updated definitive feasibility study to incorporate additional drilling and the sulphide testwork results.

Highlights from the metallurgical testing include:

Danny Callow, CEO, African Gold Group states:

“The finalisation of our comprehensive sulphide metallurgical testwork programme, culminating in the variability testwork, shows us that sulphides at the Kobada gold project can be treated through a gravity and CIL process. The process design on gravity and CIL for the oxides as presented in our July 2020 Definitive Feasibility Study is suitable for treating the sulphides as well, and this will allow us to add substantial resources to our overall resource base. The sulphides are free-milling, show excellent recoveries and consume low amounts of lime and cyanide, making this a very efficient operating cost process.”

“These results will feed into our updated DFS, allowing us to incorporate sulphides into the life of mine plan and we believe will add additional reserve ounces to our economic models. The wider testwork programme has been highly successful and confirms Kobada's excellent potential as a future new mine in Mali. We are looking forward to delivering an updated study in Q3-2021.”

The comprehensive metallurgical testing program was conducted by Maelgwyn South Africa (“MSA”) on composite samples from all defined mineral zones (north, south, and central domains) of the main shear zone. The final stage of this process, the variability testing has proven the consistency of being able to treat the sulphides across the extent of the ore body.

Kobada Sulphides Variability Recovery Testwork Results

Upon completion of recovery optimization testwork on a composite sample, the optimum conditions selected were tested on variability samples to determine if the selected process route and optimum conditions selected are applicable across the entire ore body. Six variability samples were selected from the North, South and Central zones. Table 1-1 below shows samples used to make up the variability samples.

Table 1-1: Variability Sample Selection

The selected process route on the oxide ore was gravity followed by cyanidation. Initial scouting testwork on the sulphide ore using the same process route as for the oxides showed gold recovery above 90% with low cyanide and lime consumptions. Therefore, the selected recovery process for the sulphides was gravity followed by intensive cyanidation on the gravity concentrate and cyanidation on the gravity middlings and tails. The following optimum leach conditions were selected for the sulphide ore:

Table 2-1 shows a summary of the variability recovery results.

The results indicate the following:

Definitive Feasibility Update

The Company is well underway to deliver an updated Definitive Feasibility Study in Q3-2021. The comprehensive update will target two key areas, namely inclusion of more than 7,000 m from the most recent drilling programme (see press release as of February 2, 2021) and inclusion of additional sulphides from the most recent metallurgical testwork into the resource and reserves.

Progress to date includes the following:

About African Gold Group

African Gold Group is a TSX Venture Exchange (TSX-V: AGG) listed exploration and development company with a focus on building Africa’s next mid-tier gold producer. The Company has a highly experienced board and management team with a proven track record in the African mining sector operating mines from development through to production. AGG’s principal asset is the Kobada Project in southern Mali, which is in an advanced stage of development having completed the 2020 definitive feasibility study and is targeting gold production of 100,000 oz per annum. As well as the initial Kobada Gold Project, other exploration locations have been identified on the Kobada, Farada and Kobada Est concessions, offering potential for an increase in resource.
