Perth, May 15, 2015 AEST (ABN Newswire) - Cardinal Resources Limited (
ASX:CDV) ("Cardinal" or "the Company") have received the results of fifteen, two kilogram samples used for diagnostic leach testing of Reverse Circulation (RC) cuttings from 12 drill holes at the Namdini project in Ghana. The samples were taken from the oxide, transitional and fresh material types within mineralised zones.
HIGHLIGHTS
- 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.
