P The gold value in this ore was amenable to direct cyanidation (over 9507o extraction). However, the extremely high cyanide consumption (7.2 kg/t) and the high ^g copper dissolution rate (1 800 ppm Cu in pregnant solution) might make this ore a poor ...Advanced stage copper-gold property in development - Morrison .3.
