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

• Drilling commenced on first hole targeting VMS Mineralization at the Main Gossan Zone

• Sulphide mineralization noted at multiple intervals so far in Hole CF-26-01

• Drilling continues

Vancouver, June 23, 2026 - Cascade Copper Corp. (CSE: "CASC"/FRA: 91O) ("Cascade" or the "Company") is pleased to announce that it has commenced the maiden drilling at its Centrefire Copper-Gold Project, located 40 kilometres from Dryden, Ontario. The first hole is collared on a high priority copper-gold Volcanogenic Massive Sulphide (VMS) target identified through inversion modelling of geophysics, historic drilling, and sampling of surface mineralization. A recent Press Release on May 11, discusses these priority drill targets.

"Having the drill turning at Centrefire marks a significant milestone for Cascade Copper," stated Jeffrey Ackert, President and CEO of Cascade Copper. "The commencement of our maiden drill program represents the first opportunity for the Company to systematically test the project's high-priority targets, and we are pleased to have Vice President of Exploration, Shannon Baird, on site to oversee the program. His presence allows for continuous review of the core at our logging facilities in Dryden and provides the flexibility to react quickly and extend holes where warranted. Encouragingly, the first boxes of core from the initial hole have already encountered sulphide mineralization, providing early confirmation that we are drilling in the right area. We look forward to advancing the program and evaluating the results as they become available."

Hole CF-26-01 was collared to intersect EM Plate 1980_flat with a conductivity-thickness (c-t) value of 495. A c-t value of greater than 400 is deemed to be highly anomalous. A highly magnetic zone is coincident with the 1980_flat conductor and is targeted in this hole as well. CF-26-01 is expected to be about 200m in depth.

Project Description

The 2,500-hectare Centrefire Cu-Au Project is located in the Wabigoon Greenstone Belt in Northwestern Ontario, ~40 kilometers northeast of Dryden and ~35 kilometers southwest of Sioux Lookout. It has been minimally explored in the past with 10 short (<75m vertical depth) drill holes, 5 surface trenches, continuous channel sampling over multi-meter intervals and geophysics, both surface and airborne including magnetics and EM surveys. Phelps Dodge explored the area between 1968 and 1970 and discovered several stacked intervals of copper, gold, and nickel mineralization within the majority of drill holes. Recent modern work by Cascade has confirmed surface mineralization, re-interpreted and modelled the EM and magnetic geophysics and defined priority drill targets from this. Note that recent surface sampling has returned values up to 2.86% Cu, 2.84 g/t Au, and 23.5 g/t Ag.

Management cautions that core visuals and grab samples are selective in nature to begin with and are not representative of the hole or property in its entirety or indicative of any grade overall. Assay results are pending and visual identification of minerals does not guarantee economic grades. These preliminary visual observations are awaiting laboratory confirmation.

About Cascade Copper

Cascade Copper is an exploration stage natural resource company engaged in the evaluation, acquisition, and exploration of copper based mineral resource properties. Cascade is focused on copper and gold, porphyry and mesothermal gold deposits in British Columbia and VMS and BIF copper, gold, and silver style deposits in Ontario. Cascade's priority is to conduct exploration using modern technology that includes 3D inversion modelling of geophysics, LiDAR elevation models, and AI enhanced Predictive Modelling from all historic and modern data inputs. Drilling is planned on several of its copper-gold targets this year. Cascade has five projects, including the Copper Plateau Copper-Moly Project, the Centrefire Copper-Gold Project, the Rogers Creek Copper-Gold Project, the Fire Mountain Copper-Gold Project, and the Bendor Gold-Tungsten Project.
