Cascade Copper Announces Field Work Completed At The Centrefire Copper-Gold Project

Executive Summary

• Completed an initial field program (October 2025) that ground‑truthed geophysical anomalies and collected 41 rock grab samples across the Centrefire Copper‑Gold Project.
• Expanded the oxidized footprint of the Main Gossan Zone to at least 600 m × 300 m and identified Banded Iron Formation (BIF) and quartz‑sulphide veining in the northeast portion of the project.
• Initiated a full 3‑D magnetic inversion of merged historic airborne and new high‑resolution drone magnetics to refine drill targets, with a planned diamond‑drilling permit application expected within the next month.

Key Details

• Field Program Scope: October 2025; 41 grab samples taken for multi‑element analysis and hyperspectral scanning across the Centrefire Project (~40 km NE of Dryden, ON).
• Main Gossan Zone Results: Surface channel assays previously returned up to 0.82 % Cu, 1.17 g/t Au, and 6.6 g/t Ag over 5 m; ground‑truthing expanded the oxidized zone to ≥600 m × 300 m.
• Geophysical Findings: Drone magnetics revealed signatures similar to the Main Gossan Zone in the northeast; magnetic inversion modeling shows disrupted BIF trends interpreted as structurally controlled and altered by hydrothermal fluids.
• Sample Highlights:
• BIF outcrop sample from NE corner (photo provided).
• Quartz‑carbonate‑sulphide veining observed on east side of project.
• Gossanous trench samples collected within Main Zone.
• Magnetic Inversion Work: Completed preliminary 3‑D inversion of historic airborne data; now merging with recent drone magnetic dataset for a comprehensive 3‑D model to aid target definition.
• Next Steps:
• Await assay results (≈ 3 weeks).
• Conduct full 3‑D magnetic inversion using combined datasets.
• Submit diamond drilling and geophysics permit application within the next month, contingent on assay return and completed modeling.
• Qualified Person: Shannon Baird, P.Geo., VP Exploration, reviewed technical information per NI 43‑101.

Notable Quotes

“During the field program in October, I was able to traverse a number of the priority magnetic anomalies… We expect to have results back from the lab in ~3 weeks, but in the meantime, we will be initiating a full 3D inversion exercise … leading to a drilling program in 2026.” – Shannon Baird, VP Exploration, Cascade Copper Corp.
