African Gold Group, Inc. announced updated test results from metallurgical testing on sulphide material from its flagship Kobada Project, in southern Mali. The results continue to advance the opportunity of increasing reserves without further drilling, by demonstrating sulphides can be processed through the oxide plant as designed in the feasibility study, thus generating a more robust mine plan with larger tonnage and increased gold output. Highlights from the metallurgical testing include: Comminution tests indicate a Bond Work Index (BBWi) of 13,5 Kwh/t with medium hardness sulphide and abrasiveness (Ai) of 0.2487; Cyanide consumption at 0.75 kg/t is a low-medium cyanide consumer and fits into current DFS plant design; Lime requirement of 0.38 kg/t indicate a very low lime consumption, meaning that operating costs for treating sulphides are expected to be low. 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 ongoing sulphide ore testwork program involved the following: Optimised cyanidation testwork; Additional comminution studies to determine optimal grind size and abrasiveness of the ore. Optimised cyanidation testwork: Cyanidation testwork indicates a low to medium cyanide consumption required for high gold dissolution rate. Other projects in the region typically consume between 0.85 – 1.38 kg/t, so this is considered a low cyanide consuming ore. Effect of Grind: Gold dissolution tests were conducted on gravity middlings and tails by varying grinds 75 to 212 µm as shown in the table below. It can be noted that dissolution of gravity middlings and tails reduced with an increase in grind size - results are in line with expectations. Further optimisation work from OMC will determine any possible changes to mill design to support finer grinding, however the rest of the process plant design can accommodate the sulphides without any further design changes. In addition, additional variability testing will take place over the next few weeks.
