Selkirk Copper Reports Additional Intersections of High-Grade Cu-Au-Ag From the Phase 1 Drill Program at the Minto Copper-Gold-Silver Mine
Press Release
April 30, 2026
Highlights
- Drilling at Minto North continues to deliver broad intervals of high-grade mineralization:
- 4.19% Cu, 2.50 g/t Au and 21.15 g/t Ag (6.2% CuEq) over 14.7 m, within a broader zone of 2.58% Cu, 1.50 g/t Au and 12.67 g/t Ag (3.8% CuEq) over 26.8 m from 177.9 m in drill hole 25SCM052.
- Drilling at Area 118 intersects high-grade Cu-Au-Ag mineralization at shallow depths. Subsequent drilling will prioritize follow-up in this area:
- 6.60% Cu, 5.18 g/t Au and 27.02 g/t Ag (8.3% CuEq) over 6.6 m, from 64 m in drill hole 25SCM098.
- 2.68% Cu, 1.81 g/t Au and 11.91 g/t Ag (4.1% CuEq) over 14.4 m, from 79.2 m in drill hole 25SCM090.
- Drilling at Ridgetop South intersects high-grade mineralization at shallow depths in a 100-metre step-out beyond previous drilling:
- 2.75% Cu, 0.77 g/t Au and 10.86 g/t Ag (3.4% CuEq) over 5.7 m, from 99 m in drill hole 25SCM089.
April 30, 2026 – Vancouver, BC and Pelly Crossing, YT – Selkirk Copper Mines Inc. (TSX-V:SCMI | FRA:IO20 | OTCQB:SKRKF) (“Selkirk Copper” or the “Company”) is pleased to announce new assay results from the recently completed Phase 1 Drilling Program at the Minto Mine in Yukon, Canada.
M. Colin Joudrie, President & CEO, commented: “We are very encouraged by the consistently high-grade results coming out of the Minto North west zones, which continue to demonstrate both continuity and strength of mineralization. Equally important is the confidence the exploration team has built through recent geological advancements which has allowed us to successfully execute large, 100-metre step-outs at Ridgetop and Area 118, each of which have delivered high grade intersections at shallow depths which are amenable to open pit extraction. Further, the exploration team’s detailed review of historical data has directly contributed to the targeting of Area 118, where we’ve intersected one of the higher-grade zones encountered in our 2025 Phase 1 program. We fully expect the integration of these results to enhance our evolving geological understanding at Minto and to positively contribute to mine plans being developed as part of our Preliminary Economic Assessment, on-track for delivery mid-year.”
Phase 1 Drill Program 2025-2026
Selkirk Copper has successfully completed its Phase 1 drill program, comprising 52,288 m of drilling in 175 holes. Drilling was conducted between August 2025 and March 2026 with four diamond drill rigs. This represents one of the largest drilling programs completed in Yukon in the last ten years. Drilling was completed safely, with no medical aid or lost-time injuries, and minimal downtime. Drilling productivity was very high, including individual drills producing more than 200 metres per day in some instances, with an average of 94 metres per day per drill throughout the entire program. High productivity and relatively low cost-per-metre enabled us to surpass the originally planned 50,000 m program, resulting in completion of 105% of the initial plan.
Reported here are assay results from holes drilled in November and December 2025 (Figure 1). Results from approximately 63% of the Phase 1 drill program have now been released. The company expects to continue releasing assay results from the Phase 1 drill program as they are received throughout the first half of 2026.
