TSXV:SCMI Stock Plummets Despite Optimistic Minto Project PEA

Selkirk Copper Mines Inc., trading on the TSXV under the ticker SCMI, plummeted by 15.70% in value on September 22, 2026. This significant decline occurred despite a major announcement made by the company regarding its Minto Project Preliminary Economic Assessment (PEA).

The PEA outlined substantial economic potential for the project, including an after-tax Net Present Value (NPV) of C$494 million and an Internal Rate of Return (IRR) of 47.8% at planning-price assumptions. The proposed restart plan envisions a 13-year mine life with processing capacity of approximately 4,100 tonnes per day.

The PEA also estimates initial capital expenditure of around C$186 million, including working capital and contingency costs. Sustaining capital over the project's lifespan is estimated at C$409 million, covering closure and rehabilitation expenses.
