The ground ore is then floated to produce a gold rich copper concentrate for filtration and sale to overseas smelters. Flotation tailings are then leached for further gold recovery. The ore processing rate is approximately 35 million tonnes per annum. Typical head grade is approximately gram per tonne gold and per cent copper.
