The PFS outlined a 2.5 million tonne per annum operation to produce an average 23,000 tonnes per annum of copper and 690,000 ounces per annum of silver at C1 costs of $1.22 per pound of copper and all-in sustaining costs of $1.36/lb, including silver credits.
Pre-production capital costs would be $155 million, including $17 million contingency, while life-of-mine sustaining capex would be just $31 million.
Using a copper price of $3/lb, the study returned a pre-tax net present value of $281 million, at an 8% discount rate.
The initial 8.8-year mine life is based on a maiden reserve of 218,000t of copper and 7.1 million ounces of silver.
