BRITISH COLUMBIA – The Red Chris copper-gold mine 80 km south of Dease Lake has made its first copper concentrate, reported owner Imperial Metals of Vancouver. Both the semi-autogenous and ball mill drive systems have been operated at 100% load. The flotation circuits and secondary regrind mill are being commissioned with low grade ore.
The project cost an estimated $643 million to build. It features a conventional open pit mine and 30,000-t/d flotation mill. It is expected to have a 28-year mine life.
Imperial noted that it is using a P&H 2800 electric cable shovel and a fleet of Cat 793 trucks in both the east and main zones. The Red Chris deposit contains 1.22 billion tonnes of measured and indicated resources that grade 0.327% Cu and 0.327 g/t Au. In terms of contained metal, that is 8.78 billion lb of copper and 12.80 million oz of gold.
