Selkirk Copper’s $494M value for Minto nearly triple its costs

AI desk brief

Selkirk Copper’s PEA for the Yukon Minto restart values the project at $494 million (US$353 million) versus $186 million in estimated costs, with a 47.8% after-tax IRR and 1.9-year payback on a 7% discount rate. The study assumes US$3,600/oz gold and US$50/oz silver, underscoring that economics are highly sensitive to PM prices, but the plan still excludes dewatering, rehab, re-servicing, pre-capex and other restart costs.

Minto’s 13-year mine plan would produce 271,000 oz gold and 2.4 million oz silver alongside 434 million lb copper. Selkirk shares fell more than 18% on Tuesday, suggesting investors focused on the heavy remaining capital, permitting and financing hurdles rather than the headline NPV.
