A new PEA outlines a slightly new vision for developing a mine at the Schaft Creek copper-gold-silver-molybdenum project.

A preliminary economic assessment prepared for Copper Fox Metals Inc. outlines a slightly new vision for developing a mine at Schaft Creek, a large copper-gold-silver-molybdenum project being advanced under a joint venture between Teck Resources Ltd. (75%) and Copper Fox (25%).

Located within the traditional territory of the Tahltan First Nation in northwestern British Columbia, Schaft Creek hosts 1.35 billion metric tons of measured and indicated resources averaging 0.26% (7.76 billion pounds) copper, 0.17 grams per metric ton (7 million ounces) gold, 1.25 g/t (54.3 million oz) silver, and 0.017% (510.6 million lb) molybdenum.

These resources serve as the basis for the PEA, which evaluates the economic and technical parameters of a 133,000-metric-ton-per-day mill and open-pit mining operation at Schaft Creek, which is slightly larger than the 130,000-metric-ton-per-day operation outlined in a feasibility study completed in 2013.

The operation outlined in the new PEA is forecast to produce roughly 5 billion pounds of copper, 3.7 million ounces of gold, 226 million lb of molybdenum, and 16.4 million oz of silver over 21 years of mining.

The initial capital needed to develop this mine is estimated to be US$2.65 billion, which is roughly 19% lower than the US$3.6 billion for the mine outlined in the 2013 feasibility study. At US$848.7 million, the sustaining capital and closure costs of the Schaft Creek mine outlined in the PEA are also significantly lower than the US$1.2 billion costs detailed in the feasibility study.

With lower capital requirements and higher metals price assumptions – US$3.25 per lb copper, US$1,500 per oz gold, US$10 per lb molybdenum, and US$20 per oz silver – the Schaft Creek mine summarized in the PEA would generate an after-tax net present value (8% discount) of US$842.1 million and after-tax internal rate of return of 12.9%.

It is expected to take about 4.8 years to pay back the initial capital investment to develop the mine.

"The significantly higher investment returns, resulting in part from project enhancements developed over the past two years, and remaining resources in the deposit on completion of the first 21 years of mining, provides a compelling view of the Schaft Creek project's financial potential," said Copper Fox Metals President and CEO Elmer Stewart.

The new mine plan reduces the footprint of the operation by moving the milling facility closer to the pit, relocating the tailings management facility closer to the mill, and reducing the number of waste rock storage facilities from three to two.

The strip ratio has also been significantly reduced from more than 2-to-1 to 1-to-1.

The PEA recommends a C$23.2 million work program ahead of a preliminary economic assessment for developing a mine at Schaft Creek. This program would include additional geotechnical drilling, metallurgical testing, and environmental and infrastructure studies.

"We are very pleased with the results of the PEA and the recommended program work of C$23 million that could be considered by the operator to advance the Schaft Creek project to the prefeasibility study stage of study and evaluation," said Stewart.

Copper Fox says it is committed to working with Teck to develop and operate the Schaft Creek project in a safe, ethical, and socially responsible manner that maximizes the benefits and economic opportunities for local First Nations and other communities, including employment, training, and using local service providers.
