Selkirk Copper: A Yukon restart positioned to deliver new Canadian copper supply by 2028

Existing infrastructure and updated resource position Minto project for mid-2028 production.

Selkirk Copper is advancing a restart of the Yukon-based Minto copper-gold-silver project, building on an updated 2025 resource and a 50,000-metre drill program, with plans to complete a preliminary economic assessment mid-2026, a feasibility study in 2027, and a production target of mid-2028.

In a market searching for reliable copper supply, Selkirk Copper is working to bring an established asset back to life. The Minto project previously operated for several years and already hosts built infrastructure, a rarity for new Canadian copper opportunities.

Management describes the company as a restart story rather than a greenfield venture. The previous operator drilled roughly 82,000 metres and discovered several new zones that were never fully developed. Selkirk has taken that technical data, refreshed the mineral resource estimate in August 2025, and used it as the platform for new planning.

Drilling to refine the plan

A 50,000-metre drill program began last summer to expand understanding of the resource and guide updated mine design. The goal is to define a 12–15 year mine life while refreshing permits and engineering.

A new model of partnership

Selkirk is partnering directly with the local First Nation, which acquired the asset out of bankruptcy and now plays an active role in the project’s direction. Selkirk First Nation's 22.3% equity ownership in Selkirk Copper is a first for a public mining equity in Canada and a key element of the development and re-start strategy.

Timeline to production

• Mid-year 2026: Preliminary Economic Assessment

• Mid-2027: Restart decision following feasibility

• Mid-2028: Targeted return to production

• Potential output of ~30,000 tonnes of copper equivalent annually
