YUKON – If all goes according to plan, there will be a new open pit and concentrator at the Casino deposit 300 km northwest of Whitehorse. Owner Western Copper Corp. of Vancouver has filed the pre-feasibility study for a project treat 120,000 t/d of sulphide ore from which gold, copper, molybdenum and silver will be recovered for 23 years. A separate carbon column operation will treat 25,000 t/d of oxide ore.
The $2.13 billion price tag includes mine development, a mining fleet, the concentrator, tailings management area, a new airstrip, camp, two gas turbine generators, and an all-weather access road to transport concentrates to Skagway, AK. The mill could be commissioned with sulphide ore in the last half of 2019.
The supergene oxide, supergene sulphide and hypogene material has a measured and indicated resource at a 0.25% CuEq cutoff is 1.1 billion tonnes grading 0.20% Cu, 0.23 g/t Au, 0.022% Mo and 1.71 g/t Au. There is also a inferred resource at the same cutoff of 1.7 billion tonnes at slightly lower grades.
The Casino property also has a leached cap-oxide gold zone suitable for heap leach recovery. That measured and indicated resource is 84.0 million tonnes at 0.04% Cu, 0.40 g/t Au, 0.020% Mo and 2.57 g/t Ag. The leachable inferred resource is 17.0 million tonnes at 0.01% Cu, 0.31 g/t Au, 0.008% Mo and 1.93 g/t Ag.
