Selkirk Copper (TSXV:SCMI) - Doubles Mineral Resource Estimate, Minto to Restart by 2028
Interview with Colin Joudrie, CEO, Selkirk Copper Our previous interview: https://www.cruxinvestor.com/posts/selkirk-copper-mines-tsxvscmi-restart-developer-targets-mid-2028-production-10866 Recording date: 26th August 2026 Selkirk Copper Mines is executing a restart of the past-producing Minto copper-gold-silver mine in Yukon, Canada, an asset that operated successfully for 16 years before its most recent operator entered bankruptcy in 2023. Rather than building a new mine, Selkirk is rehabilitating existing infrastructure - a 4,100 tonne-per-day processing plant, underground and open-pit workings, a 400-person camp, water treatment facilities and grid power - an approach management argues meaningfully compresses both the capital and time required to reach production. The exploration case has strengthened materially over the past year. A Phase 1 drill programme of 52,288 metres, completed in mid-2026, underpinned an updated Mineral Resource Estimate showing a 182% increase in Measured & Indicated copper to 940 million pounds, alongside comparable increases in gold and silver. An ongoing Phase 2 programme, targeting 50,000 metres, is now more than 90% complete and running ahead of schedule, with recent assay results including a 13.12% copper-equivalent intercept at the high-grade Minto North zone and step-out drilling that suggests further expansion potential to the south. Roughly half of the resource growth is attributed to drilling success, with the remainder reflecting updated metal price assumptions. A structural feature distinguishes Selkirk's economics from the prior operation: a gold and silver streaming agreement that previously diverted precious metals revenue to an outside party was eliminated during the bankruptcy process. CEO Colin Joudrie describes this as a rare outcome that leaves the company with full exposure to gold and silver, which together represent roughly 35% of the deposit's value. Management also plans metallurgical upgrades - adding gravity recovery circuits and a permanent crusher circuit - intended to lift precious metals recovery and reduce milling costs relative to historical performance. The near-term roadmap is defined. A Preliminary Economic Assessment, incorporating the enlarged resource base, is targeted for completion in Q3 2026 and will provide the first formal cost and production estimate under Selkirk's ownership. A Feasibility Study is expected to begin around the end of September 2026, feeding into a final investment decision targeted for mid-2027, with first production targeted for mid-2028. Restart capital costs are currently expected to be in the range of C$200 million, financing for which - alongside potential offtake and streaming arrangements - is expected to be arranged over the next 12-18 months. Joudrie situates the restart within a broader copper market thesis: negative treatment and refining charges, ageing global mine supply, and recent major operational failures elsewhere have left the market structurally short, a gap he believes new, quickly-executed supply like Minto is well positioned to help fill. Risks include permitting amendment timing, which remains outside the company's direct control, Yukon-specific cost inflation in contract mining, and the execution risk of translating a substantially larger drill database into a coherent, financeable mine plan. The PEA release stands as the clearest near-term test of whether the exploration success translates into a credible economic case.
