Five holes completed for 607 metres
All drill holes show sulphide mineralization with holes CF-26-03 through -05 showing significant copper sulphide mineralization as chalcopyrite

Vancouver, British Columbia – TheNewswire - July 13, 2026. Cascade Copper Corp. (CSE: “CASC”/FRA: 91O) (“Cascade” or the “Company”) is pleased to announce that it has completed its maiden drilling program at the Centrefire Copper-Gold Project, located 40 kilometres from Dryden, Ontario. All five holes intersected sulphide mineralization indicative of a Volcanogenic Massive Sulphide (VMS) environment.

"After seeing the core from all five holes at the Centrefire Project, I am quite encouraged about the overall copper potential of the hydrothermal system," stated Shannon Baird, Vice-President of Exploration of Cascade Copper. "The amount of chalcopyrite in several zones within the holes, especially holes 03, 04, and 05 have exceeded my expectations. This was an excellent first pass, and I look forward to seeing the results from the analysis.

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.

What’s Next

Drilling has concluded at the Centrefire Copper-Gold VMS project, while logging and sampling continues at site with Cascade’s VP of Exploration, Mr. Shannon Baird, overseeing the operation. Priority sampling will continue with samples being submitted to the lab on a hole-by-hole priority basis. Initial results will be expected in six to eight weeks.

Pending results, a Bore Hole Electro Magnetic (BHEM) survey will be contemplated to test for hidden VMS style conductors in the vicinity of the current drilling. This would lead to a follow-up phase 2 drill program that would target along strike and to depth of the best intersections.

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.
