Cascade Copper Signs Drill Contract for Maiden Program at the Centrefire Copper-Gold Project Near Dryden, NW Ontario

• Minimum 600m of NQ size core is planned with ability to expand program

• Priority VMS targets defined

• Projected start in June 2026

Vancouver - May 13, 2026. Cascade Copper Corp. (CSE: "CASC"/FRA: 91O) ("Cascade" or the "Corporation") is pleased to announce that it has signed a drilling contract for a maiden minimum 600-metre diamond drilling program at its Centrefire Copper-Gold Project, located 40 kilometres from Dryden, Ontario. The Corporation expects the drill contractor to mobilize in early June 2026, with drilling focused on priority copper-gold Volcanogenic Massive Sulphide (VMS) targets identified through inversion modelling of geophysics, historic drilling and sampling of surface mineralization. A recent Press Release on May 11, discusses the priority drill targets. A live event to discuss Cascade's drill targets and drill contract will occur Wednesday May 13 at 12pm. Please register here.

"The signing of the drilling contract is the obvious next step for Cascade to verify and evaluate the extensive modelling and interpretation of the mineral systems at the Centrefire Project," stated Jeffrey Ackert, President of Cascade Copper. "Our exploration work done to date on the project has predicted a robust VMS system that is begging to be tested. If the model is proven, it opens up the possibility for similar mineralization across the entire 8 kilometre trend."
