Selkirk Copper and Talisker Resources File NI 43-101 PEA Reports for Yukon Copper and BC Gold Projects

Two Canadian junior miners filed independent Preliminary Economic Assessment technical reports on November 5, 2026, formalizing economic studies previously announced in September for projects in western Canada.

Selkirk Copper Mines Inc. (TSXV: SCMI, OTCQX: SKRKF) filed on SEDAR+ the NI 43-101 PEA for its 100%-owned Minto copper project in Yukon, Canada, with an effective date of September 21, 2026. The assessment outlines a 13-year mine life at a 4,100-tonne-per-day mining and milling rate, generating peak annual production of 27,200 tonnes of copper-equivalent contained in concentrate. The project carries an after-tax net present value of C$494 million at a 7% discount rate and an internal rate of return of 47.8%.

Talisker Resources Ltd. (TSX: TSK, OTCQX: TSKFF) simultaneously filed its NI 43-101 PEA for the Bralorne Gold Project in British Columbia, also with a September 21, 2026 effective date. At a base-case gold price of US$3,500 per ounce, Bralorne carries an after-tax NPV of C$1.0 billion at a 5% discount rate and a 31.3% internal rate of return. At the then-spot price of US$4,300 per ounce, those figures rise to C$1.9 billion and 67.2%, respectively. The project requires initial capital of C$416 million and sustaining capital of C$782 million. Both PEAs are preliminary in nature and rely substantially on inferred mineral resources.
