Cascade Copper Samples High Grade Copper, Gold, and Silver, at its Copper Plateau Porphyry Project, South-Central BC

Executive Summary

• Cascade Copper released assay results from seven bedrock grab samples collected during its summer 2025 field program at the Copper Plateau Porphyry project, with two samples showing exceptionally high grades (up to 13.04% CuEq).
• The results confirm that historic soil anomalies are underlain by significant copper‑molybdenum mineralization, supporting plans for an induced‑polarization (IP) survey and upcoming diamond drilling.
• Permit applications for the IP survey and drilling are pending; a Notice of Work has been submitted.

Key Details

• Sample A0284805: 13.04% CuEq (10.6 % Cu, 0.58 g/t Au, 66.9 g/t Ag, 0.18 % Mo).
• Sample A0284803: 1.22% CuEq (0.86 % Cu, 0.28 g/t Au, 7.12 g/t Ag, 23.9 ppm Mo).
• Five of seven samples returned highly anomalous assays; the remaining two were not disclosed.
• Pending Analyses: 45 additional bedrock samples are awaiting assay and hyperspectral scanning.
• Sampling Context: Samples taken from surface outcrops within >250 ppm Cu soil anomaly corridors, some outside the main historic drill zone.
• Technical Verification: All samples processed by ALS Canada Ltd. using fire‑assay fusion (Au‑ICP) and 48‑element ICP‑MS methods; QA/QC performed per ISO/IEC 17025:2005 and ISO 9001:2015 standards.
• Conversion Assumptions for CuEq: Cu @ $4/lb, Mo @ $25/lb, Au @ $2,500/oz, Ag @ $40/oz.
• Next Steps:
• Commission an IP geophysical survey covering the south, west, and northwest extensions of the anomaly.
• Plan multiple drill holes to test down‑plunge high‑grade potential indicated by historic drilling.
• Permitting for both the IP survey and drilling is underway (Notice of Work submitted).
• Management Comment: Shannon Baird, VP Exploration, highlighted that the high‑grade grab samples confirm a bonafide bedrock source for the soil anomalies and justify focused drilling.

“This exercise confirms that there is a bonafide bedrock source for the soil anomalism and gives Cascade confidence in focusing on drilling these areas.” – Shannon Baird, Vice President of Exploration, Cascade Copper Corp.
