Cascade samples 2.86% Cu, 2.84 g/t Au at Centrefire

Executive Summary

• Cascade Copper Corp. released initial assay results from a Q4 2025 field program involving ground truthing and rock sampling at its Centrefire copper-gold project in Ontario.
• Results from 13 of 41 collected samples confirm high-grade copper, gold, and silver mineralization, particularly at the Main Gossan Zone (MGZ), with significant intercepts including 2.86% Cu, 2.84 g/t Au, and 15.7 g/t Ag.
• The company plans to use these results, combined with 3-D geophysical modeling, to refine drill targets for a maiden drill program, with a permit submitted and approval expected in Q1 2026.

Key Details

• Sample Collection: 41 rock samples collected across the project in Q4 2025; 13 results received, 16 pending.
• Location: Samples primarily located within the vicinity of the Main Gossan Zone (MGZ).
• Key Assay Highlights:
  • Highest reported values: 2.86% Cu, 2.84 g/t Au, and 15.7 g/t Ag.
  • Five of the 13 grab samples assayed greater than 1% copper.
  • Four samples assayed greater than 1.0 g/t gold.
  • Four samples assayed greater than 10 g/t silver.
  • One specific sample returned 1.46% Cu, 0.452 g/t Au, 23.5 g/t Ag, and 0.23% tungsten.
• Geological Context: Mineralization is associated with banded iron formation (BIF) and volcanogenic massive sulphide (VMS) styles. The MGZ covers an area of over 1,000 metres by 800 metres.
• Exploration Strategy: Results indicate disruption in magnetic and conductor trends associated with intense hydrothermal activity. 3-D modeling is being used to delineate targets for the upcoming maiden drill program.
• Regulatory/Permit Status: A drill permit has been submitted; approval is expected within Q1 2026.
• QA/QC: Samples analyzed by ALS Canada Ltd. using 30-gram fire assay fusion (Au-ICP21) and 34-element four-acid digest ICP-AES (ME-ICP61).
• Technical Disclosure: Prepared by Shannon Baird, PGeo, Vice-President of Exploration.
• Caution: Management notes that grab samples are selective and may not represent true underlying mineralization.

Notable Quotes

• "These initial results from the Q4 field program confirm the outstanding copper, gold and silver mineralization potential at Centrefire. From the geophysical signatures, we can see that the disruption in the magnetic and conductor trends are associated with increased mineralization and likely intense hydrothermal activity. This sampling program and these results show mineralization at the Main Gossan zone for more than one kilometre in strike over a width of almost 800 metres." — Shannon Baird, Vice-President of Exploration
• "Our ongoing 3-D modelling of the geophysics and surface assay results will help refine our drill targets for an upcoming maiden drill program." — Shannon Baird, Vice-President of Exploration
