[Video Enhanced] Selkirk Copper 50,000 meter Drill Program Aims to Establish a 12-15 Year Mine Life

Executive Summary

• Selkirk Copper Mines released new assay results from its ongoing 50,000‑meter Phase 1 drill program at the Minto Mine, confirming high‑grade copper–gold–silver mineralization in multiple zones.
• Hole 25SCM042 infilled a ~90 m gap in the Minto East zone, returning 3.37% Cu, 1.88 g/t Au and 14.96 g/t Ag over 6.5 m (CuEq 3.45%).
• The company is progressing toward an updated integrated mine plan, trade‑off study and Preliminary Economic Assessment targeted for mid‑2026, supporting a planned 12–15 year mine life restart.

Key Details

• Drill Program Status: 39,315 m completed in 144 holes (78% of Phase 1); expected completion by mid‑March 2026.
• Hole 25SCM042 (Minto East):
• 6.5 m interval: 3.37 % Cu, 1.88 g/t Au, 14.96 g/t Ag → CuEq 3.45%.
• Broader zone: 15.2 m of 2.50 % Cu, 1.16 g/t Au, 9.90 g/t Ag starting at 101.3 m depth.
• Ridgetop Zone: Five holes drilled in October intersected mineralization above the 2025 MRE open‑pit cutoff (0.30 % CuEq), extending near‑surface targets south and southwest.
• Resource Implications: Re‑examination of historic drill database and gap‑testing are improving confidence that defined lenses will be amenable to long‑hole stoping, a cost‑effective underground method.
• Economic Impact: Extinction of the 2007 gold‑silver stream (due to bankruptcy) frees ~35 % of ore value; future by‑product revenue from gold (~US$5,000/oz) and silver (~US$80/oz) will flow directly to Selkirk Copper.
• Future Milestones:
• Trade‑off study and Preliminary Economic Assessment (PEA) slated for mid‑2026 release.
• Updated integrated mine plan to guide design options, capital cost estimates, production rates, and environmental/safety objectives.
• Financing Note: Selkirk Copper raised C$45 million in late 2025 to fund exploration and planning activities.

Notable Quotes

“These latest drill results continue to grow our confidence in the Minto property… we are making progress to have sufficient grade and continuity to support our targeted 12‑15 year mine life and restart plan,” – Colin Joudrie, President & CEO.

“The results from hole 25SCM042 strengthen our view that once defined, these mineralized lenses will be amenable to long‑hole stoping, a cost‑effective underground mining method,” – Colin Joudrie.
