1. Introduction1.1. Site background. The quartz-carbonate vein- and brittle-ductile shear zone-hosted gold (Au) deposit at Giant Mine is located in the Kam Group of the Archaean-age Yellowknife Greenstone Belt (Canam, 2006).Most Au in the Giant deposit is considered refractory, mainly hosted within the crystal structure of arsenopyrite (FeAsS) and to a lesser degree arsenian pyrite (FeS 2).

Established at claims staked in 1935, the Giant mine site spans the west side of Yellowknife Bay, from the Yellowknife to the mouth of Back Bay. In the mid-1940s, Government of Canada scientists determined that roasting ore from the site at high temperatures would be the most effective method for extracting gold from the Giant mine.15 Canadian
