Selkirk Copper Announces Positive PEA for the Minto Project, Delivering After-Tax NPV of C$494M with 48% IRR
Strong Platform to Realize Concentrate Production by 2028 2026 Minto Project Preliminary Economic Assessment Highlights Target Mine Life, Mill Throughput, and Robust Economics Across Commodity Price Scenarios 13 year mine life at 4,100 tonnes per day ("tpd") mining-milling rate that produces peak 27,200 t copper-equivalent1 contained in concentrate or 48,700 t of high-grade copper-gold-silver concentrate at peak production NPV7% of C$494M, 47.8% internal rate of return ("IRR"), and 1.9 year after-tax payback from first production at US$5.00/lb copper, US$3,600/oz gold and US$50/oz silver ("Planning Prices") NPV7% of C$1,023M, 78.2% IRR, and 1.3 year after-tax payback from first production at US$6.50/lb copper, US$4,300/oz gold and US$65/oz silver ("Spot Prices") NPV7% of C$1,385M, 96.3% IRR, and 1.0 year after-tax payback from first production at US$7.50/lb copper, US$5,400/oz gold and US$75/oz silver ("Upside Prices") Capital Efficient Leveraging Existing Infrastructure The Project demonstrates a strong Capital Efficiency Ratio2 with an after-tax NPV to initial capital ratio of 2.7:1 at Planning Prices, increasing to 5.5:1 at Spot Prices highlighting leverage to higher copper, gold and silver prices. The high capital efficiency ratio is a result of road, barge facilities, power transmission line, substation, fuel farm, services, camp, warehouse, workshops, grinding and milling infrastructure, water treatment plant, existing underground development, and general on-site services that are in good working order requiring negligible capital investment to make operational Mine Life-to-Payback2, a ratio which describes the potential for the asset to return capital and provide exposure to positive copper supply-demand fundamentals through the planned mine, is 6.8:1 at Planning Prices Exploration Growth Potential Beyond Current Study Phase 1 52,288 metre drill program completed in April 2026 increased Measured & Indicated Resources in the 2026 Mineral Resource Estimate ("MRE") by 280% and increased contained copper, gold, and silver by 182%, 184% and 188% respectively above the 2025 Mineral Resource Estimate Phase 2 50,000 metre drill program initiated in May 2026 is now 98% complete, the results of which are not included in the 2026 MRE or 2026 PEA mine plan but which continue to extend and expand zones of known mineralization reinforcing significant upside mine life and production potential Water Management and Permitting In designing the Minto Project restart, significant attention was placed on ensuring all of the planned development work and planned operations, including water management, would be within the boundary of the existing Quartz Mining License and would minimize impact on the environment.
