Cascade Copper Completes Initial Field Program at Centrefire Project

Vancouver, British Columbia — November 6, 2025 — Leads & Copy — Cascade Copper Corp. (CSE: CASC) has completed an initial field program involving ground truthing geophysical anomalies and rock sampling at its Centrefire Copper and Gold Project in Ontario, Canada.

The field work, conducted in October, included the collection of 41 rock samples across the Project, including the area recently covered by high resolution drone magnetics over the northeast portion of the Centrefire claims. The company aims to explore the potential continuation of mineralization found at the Main Zone, where previous surface channel sampling yielded assays up to 0.82% copper, 1.17 g/t gold, and 6.6 g/t silver over 5 meters, along strike to the northeast under thin sandy till cover.

Prospecting at the Main Gossan Zone has expanded the oxidized footprint to at least 600 meters by 300 meters. Ground truthing and rock sampling over the northeast portion, where drone magnetics revealed a similar signature to the Main Gossan Zone, led to the discovery of Banded Iron Formation (BIF) and quartz-sulfide veining. Preliminary magnetic inversion modeling indicates that Banded Iron Formation trends are disrupted and interpreted to be structurally influenced and altered by hydrothermal fluids.

Shannon Baird, VP Exploration for Cascade Copper, stated that the field program involved traversing and sampling priority magnetic anomalies identified during a review of the high-resolution magnetic survey. Baird noted the discovery of more rusty and oxidized rock within the Main Zone, expanding the surface expression. The company expects lab results in approximately three weeks and will initiate a full 3D inversion of the merged magnetic data to refine targets at Centrefire, leading to a drilling program in 2026.

A preliminary 3D magnetic inversion was completed on historic airborne magnetic data over the western portion of the Project to validate the modeling. The company has started an exercise to merge the historic airborne magnetics with the recent drone magnetics and perform a 3D inversion on the combined data. This will assist in subsurface structural and geological modeling, as well as identifying potential zones of alteration and mineralization for future drilling campaigns.

The recent magnetic inversion modeling shows a strong correlation between magnetic disruptions and anomalous to high-grade copper and gold mineralization in the western half of the project. The company believes that a similar 3D magnetic inversion using the high-resolution drone magnetic survey data will help delineate drill targets, especially in the eastern portion of the Project, where minimal outcrop exposures and thin sandy till cover make surface prospecting challenging.

Cascade Copper plans to submit a diamond drilling and geophysics permit application within the next month, following the return of assays, the completion of the Project-wide 3D magnetic inversion modeling, and the compilation of recent and historic data.

The technical information was reviewed by Shannon Baird, P.Geo., VP Exploration of Cascade Copper Corp.

Management cautions that grab samples are selective and may not represent true underlying mineralization.
