- 99% gold recovered from oxide samples
- 95% gold recovered from transition samples
- 84% gold recovered from fresh samples
- These high gold recovery rates indicate favourable metallurgy
The primary purpose of the cyanide leach test work was to establish what level of gold could be recovered by a simple cyanidation leach process.
Each sample selected was thoroughly mixed by passing the entire sample three times through the riffle splitter, then splitting off a ~2.0 kg sample.
The samples were weighed, labelled and bagged individually and sent to the SGS Laboratory, Ouagadougou, Burkina Faso for Bottle Roll (BLEG) cyanide leach tests. Each entire sample was pulverised to a fineness with 91% passing through a 75 micron mesh. Each sample was assayed by Fire Assay in triplicate by the FAA505 method.
A 2,000 gm pulverised sample was then bottle rolled for 24 hours in a cyanide mixture and compared with the fire assays to obtain estimates of recoveries.
