A bulksulphideconcentrate representing 7% to 11% of the originalmill feedis then produced with a grade of 30 to 50 grams ofgoldper tonne and agold recoveryof 87% to 92% into the concentrate. Theflotation concentrateis re-ground to approximately 90% passing 20 microns.

Themineis expected to produce 200 905 oz ofgoldover the five-year life-of-mine. The existingmine’s site footprint and 2.5-million-tonne tailings storage facility are permitted.

Elemental gold(and silver as well) is soluble in mercury, so that, when particles of themetalare brought into contact with a fresh mercury surface, they are wetted and dissolved, forming an alloy called amalgam. This phenomenon is exploited for the recovery and concentration offine particulate gold…
