Operations

Ore is treated using a two stage crushing process followed by a two stage grinding circuit that consists of a semi autogenous grinding mill and a ball mill Most of the ground ore is fed to a gravity circuit that recovers about two thirds of the gold which is then smelted on site to form doré bars Flotation recovers the rest of the gold producing a gold bearing pyrite concentrate.
