Selkirk Copper's Final Phase 1 Drill Program Results Deliver High-Grade Mineralization Intersected Across Five Target Areas, and Rapid Progress on the Phase 2 Drill Program

Highlights Drilling at Area 118 has confirmed discovery of the high-grade 301 Lens beneath previous drilling: 4.39% Cu, 7.60 g/t Au, and 21.07 g/t Ag (10.22% CuEq) over 4.1 m, within a broader interval of 1.56% Cu, 2.26 g/t Au, and 7.63 g/t Ag (3.31% CuEq) over 15.7 m, from 278.6 m in 26SCM157 Within this interval, individual one-meter bornite-rich samples returned grades as high as 4.6% Cu, 23.1 g/t Au, and 26.4 g/t Ag. Drilling at Minto East continues to intersect high-grade mineralization beneath the limits of previous drilling: 3.77% Cu, 6.74 g/t Au, and 23.68 g/t Ag (8.99% CuEq) over 3.8 m, within a broader interval of 1.38% Cu, 2.34 g/t Au, and 8.67 g/t Ag (3.20% CuEq) over 11.3 m, from 639.7 m in 26SCM134 Drilling at the 117 Lens beneath the Area 2 Pit has intersected broad zones of copper-gold-silver mineralization as well as high grade intervals, including: 2.93% Cu, 1.50 g/t Au, and 16.37 g/t Ag (4.19% CuEq) over 5.0 m, from 325.4 m in 26SCM142 0.63% Cu, 0.08 g/t Au, and 1.74 g/t Ag (0.70% CuEq) over 47.9 m, from 348.1 m in 26SCM167 Drilling at Minto North continues to delineate high-grade mineralization in the 202 Lens: 3.56% Cu, 2.34 g/t Au, and 21.42 g/t Ag (5.48% CuEq) over 3.7 m, within a broader interval of 0.89% Cu, 0.49 g/t Au, and 4.84 g/t Ag (1.29% CuEq) over 21.7 m, from 195 m in 26SCM131 Drilling at Ridgetop continues to intersect broad intervals of near-surface mineralization: 0.46% Cu, 0.14 g/t Au, and 1.57 g/t Ag (0.58% CuEq) over 69.6 m, from 13.7 m in 26SCM137 The 50,000 metre Phase 2 drill program is advancing rapidly, with 14,000 metres completed during the first month of drilling.
