Cascade Copper samples 13.04% CuEq at Copper Plateau

Executive Summary

• Cascade Copper Corp. reported high-grade copper, gold, and silver assay results from seven bedrock samples collected during its summer 2025 field program at the Copper Plateau porphyry project in south-central British Columbia.
• Five of the seven samples returned highly anomalous assays, including a significant sample (A0284805) returning 13.04% CuEq, confirming a bedrock source for historic soil anomalies and validating the area's potential for resource expansion.
• The company has completed the Notice of Work (NoW) submission for diamond drilling and induced polarization (IP) surveys, with permit applications currently pending, and plans to commission IP surveys and drill holes to test down-plunge high-grade potential.

Key Details

• Sample Results (Seven Assays Received):
  • 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.
  • Note: The remaining five samples also returned highly anomalous assays, though specific values were not listed in the highlights.
• Pending Analysis:
  • 45 additional representative bedrock samples have been submitted for mineral analysis and hyperspectral scanning.
• Project Context:
  • Location: Copper Plateau porphyry project, south-central BC (between Penticton and Princeton), 90% owned by Cascade.
  • Size: 2,789 hectares.
  • Geological Setting: Located south of the former Brenda copper mine and within the Quesnel terrane, near other major copper deposits like Copper Mountain and Teck's Highland Valley.
  • Significance: Samples were taken from apparent surface outcrop in highly prospective areas, some outside the main drilled zone, confirming that historic soil sampling coincides with significant bedrock mineralization.
• Next Steps & Permitting:
  • IP Survey: Plans to commission an induced polarization (IP) survey covering south, west, and northwest extension areas where soil sampling shows anomalous copper and molybdenum.
  • Drilling: Plans to drill several holes to test down-plunge high-grade potential indicated by historic holes carrying significant mineralization at depth.
  • Status: Notice of Work (NoW) submission completed; permit application status for diamond drilling and IP survey is pending.
• QA/QC:
  • Samples submitted to ALS Canada Ltd. (Kamloops, B.C.).
  • Analysis performed using ALS's 30-gram fire assay fusion method (Au-ICP21) with ICP-AES finish for gold, and 48-element four-acid digest ICP-MS analysis (ME-MS61) with additional ore grade element analysis.

Notable Quotes

• Shannon Baird, Vice-President of Exploration: "Although outcrop on the Copper Plateau is rare, we were able to take some samples from within the highly prospective soil anomaly corridors that we see as potential resource expansion areas. This exercise confirms that there is a bonafide bedrock source for the soil anomalism and gives Cascade confidence in focusing on drilling these areas. The high-grade sample, A0284805, is an example of the veining we see in the core that consistently carries double-digit percentage copper. Sample A0284803 is also incredibly significant as it is mineralized intrusive without much veining and still carries 0.86 per cent copper."
