31 July 2021 – TSX listed African Gold Group has confirmed that oxides and sulphides are to be incorporated into the updated feasibility study at the Kobada gold project in southern Mali. WhyAfrica’s Hawks Eye is on African Gold’s Kobada in Mali.
Results of the company’s comprehensive sulphide testwork programme will be incorporated into an updated Definitive Feasibility Study (DFS).
According to Danny Callow, CEO of the African Gold Group, 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.
Callow says that the company is continuing its work on updating mineral resource estimates (MRE) and an updated DFS to incorporate additional drilling and the sulphide testwork results.
“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 Carbon In Leach (CIL) process.
“The process design on gravity and CIL for the oxides as presented in our July 2020 DFS 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,” says Callow.
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 is in an advanced stage of development. African Gold Group is targeting gold production of 100,000 ounces 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.
