94% Average Gold Recovery from Preliminary Bottle Roll Tests
- Gold recoveries average 94% from preliminary leach tests
- Individual samples average over 95% recovery from >1g/t Au
- Results demonstrate potential for conventional, low-capex and low-cost cyanide leach processing
Many Peaks Minerals Ltd announced assay results from LeachWell bottle roll leach tests conducted on diamond core samples from the Ouarigue prospect at the Ferké Gold Project in Côte d'Ivoire. Preliminary test results from sulfide-bearing fresh rock indicate gold mineralisation at Ferké is non-refractory, with bottle roll assays averaging 94% recovery. These results provide an initial basis for assessing reasonable prospects for eventual economic extraction to support mineral resource estimation. The non-refractory nature of the mineralisation suggests Ferké is amenable to cyanide leach processing, a lower-capital cost extraction method suitable for the bulk-tonnage scale target being outlined in recent drilling success. Further metallurgical work will confirm processing viability and assess associated costs with the extraction method. Planned work is anticipated to confirm whether similar leach recoveries can be achieved using commercially viable cyanide concentrations under a range of milling and processing conditions. The results will support estimates of gold extraction and optimised recovery across different mineralised host rocks, informing future economic modelling.
Further metallurgical test-work is planned to better define a metallurgical recovery under practical processing conditions and to optimise recoveries. The Company is also preparing for the next RC drilling campaign to commence in November, followed by resumption of diamond drilling, focused on expanding mineralisation.
