African Gold Group has announced 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.
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.”
