Copper North Mining Corp of Vancouver announced the preliminary economic assessment for the Carmacks Copper-gold-silver property is now available. The project lies 220 km north of Whitehorse near the southern end of the Dawson district.
The inclusion of gold and silver recovery in the flowsheet leads to the following economic parameters. The base case for Carmacks assume a copper price of USD 2.50/lb, gold at USD 1,300/oz and silver at USD 17.50/oz. The pre-tax net present value (8% discount) would be CAD 11.9 million, and the internal rate of return 9.4%. Undiscounted and pre-tax the NPV would be USD 118.2 million and after tax USD 72.2 million. The project needs a preproduction injection of cash in the order of CAD 263.6 million and generate an annual net operating cash flow between CAD 39 million and CAD 79 million. The all-in sustaining cost of producing a pound of copper is estimated at USD1.16/lb.
Copper North said that the project will be an open pit with oxide ore treated in an agitated leach and sold as cathode. After the copper is removed from solution, the remaining liquid will undergo cyanidation and carbon-in-leach to recover gold and silver that will be smelted into dor¨¦ bars. Tailings will be filtered and dry stacked. The property also contains sulphide mineralization that has not yet been figured into production.
The in pit measured and indicated resource is 11.55 million tonnes averaging 0.977% Cu, 0.435 g/t Au and 4.34 g/t Ag. The oxide portion of the deposit contains 3.7 million measured and indicated tonnes grading 0.50% Cu, 0.132 g/t Au and 2.011 g/t Ag plus 800,000 inferred tonnes grading 0.42% Cu, 0.119 g/t Au and 1.910 g/t Ag. The sulphide mineralization contains 3.7 million measured and indicated tonnes grading 0.60% Cu, 0.128 g/t Au and 2.288 g/t Ag plus 4.4 million inferred tonnes grading 0.55% Cu, 0.123 g/t Au and 2.081 g/t Ag.
