Casa talks 2026 Congress, Arsenault exploration plans

Executive Summary

• Casa Minerals Inc. announced its 2026 aggressive exploration and development strategy for its two primary assets: the Congress Gold Mine project in Arizona and the Arsenault Project in British Columbia.
• For the Congress project, the company aims to conduct systematic drilling to bring the asset to National Instrument 43-101-compliant resource standards, building on confirmatory drill programs that have validated portions of historical data.
• For the Arsenault project, the company highlighted the completion of a 3-D induced polarization (IP) geophysical survey in 2025, which identified significant chargeability anomalies and multiple high-priority drill targets for the upcoming field season.

Key Details

• Congress Gold Mine Project (Arizona):
  • Objective: Advance exploration and development targeting gold, silver, and copper mineralization.
  • 2026 Goals: Conduct systematic drilling to define resources to modern NI 43-101 standards; define a pathway for rapid resource definition; expand exploration in priority target areas.
  • Historical Context: Previous operators (including Echo Bay Mines) reported estimates of 400,000 to 500,000 tons at grades of approximately 0.3 oz/t (9.33 g/t) gold in certain zones. The mine historically produced approximately 400,000 to 500,000 ounces of gold through 1992.
  • Disclaimer: Historical estimates are disclosed solely for context, have not been verified by a current qualified person, do not conform to current NI 43-101 standards, and are not classified as current mineral resources or reserves.
• Arsenault Project (British Columbia):
  • Asset Type: Copper-gold-silver project.
  • 2025 Survey Results: Completed a state-of-the-art 3-D ground-based IP survey covering approximately 12 square kilometres with 60 kilometres of survey lines.
  • Key Findings: Generated compelling geophysical signatures including significant chargeability anomalies indicating potential sulphide mineralization, substantial scale and continuity, and strong correlation with 2017 airborne electromagnetic survey results.
  • Outcome: Multiple high-priority drill targets identified based on signatures management has successfully followed to discovery in similar settings.
• Strategic Positioning:
  • The company holds a 90% interest in the Congress gold mine and is advancing multiple projects in British Columbia, including Arsenault.
  • Management cites operational flexibility due to projects spanning two jurisdictions (Arizona and BC).
• Future Communications:
  • The company anticipates releasing comprehensive technical details and specific program parameters for both projects in follow-up news releases as planning is finalized.

Notable Quotes

• "Casa is well positioned to capitalize on the strengthening commodities market with two highly prospective projects at different stages of advancement," stated Farshad Shirvani, president and chief executive officer. "At Congress, we have a clear path forward to define resources to modern standards on a historically productive gold system. At Arsenault, our recent geophysical work has identified compelling drill targets with signatures our team has successfully followed to discovery in similar settings. We look forward to an active 2026 field season across both properties."
