GOLD: Centerra, Premier Gold release Hardrock feasibility study

ONTARIO – Centerra Gold of Toronto and Premier Gold Mines of Thunder Bay, ON, have released the feasibility study for their Hardrock gold project in Gerladton. Initial capital cost will be $1.25 billion including a contingency of $131 million. The project has a payback of 4.5 years.

The study examines an open pit and mill to be built on the property. Life-of-mine is expected to be 14.5 years with a production of 288,000 oz annually. Mill throughput will be 27,000 t/d, and the all-in sustaining cost per ounce will be $780 (US$600). The after tax net present value (5% discount) is $709 million and the internal rate of return will be 14.4%.

The Hardrock deposit contains a probable reserve of 141.7 million tonnes grading 1.02 g/t Au with a 0.33 g/t cut-off. The reserve contains 4.2 million oz of gold.

The partners have not yet made a development or construction decision. The project will have to be de-risked, permits secured, and discussions held with local First Nations.
