Minto Project Sees Copper Resource Grow 182% Amid Tight Market Conditions

The copper market is facing a prolonged period of structural tightness due to underinvestment in new mine development and surging demand from the energy transition. Past-producing mines with retained infrastructure, a known resource, and a credible path to near-term production have become attractive assets for investors.

Selkirk Copper's Minto 2026 Resource Update revealed a significant increase in contained copper, from around 333 million pounds to 940 million pounds, a 182% growth. This expansion is attributed to new drill-defined mineralisation and economic cut-off optimisation driven by higher metal price assumptions.

The resource estimate separates underground and open pit components, with the underground portion carrying higher average grades. The Phase 1 drilling programme achieved an unusually high 87% success rate, indicating a repeatable targeting model developed through prior operations. A Phase 2 drill programme is approximately 75% complete, and its results are expected to further increase the resource base.
