Vancouver, British Columbia--(Newsfile Corp. - February 26, 2026) - Casa Minerals Inc. (TSXV: CASA) (OTCQB: CASXF) (FSE: 0CM) (the "Company" or "Casa") is pleased to provide a corporate update and announce its plans for an expanded exploration program in 2026 across its mineral properties in Arizona, USA and British Columbia, Canada.
2026 EXPLORATION STRATEGY
In response to strengthening global demand for resources and commodities, Casa is advancing aggressive exploration and development plans for its key mineral assets:
Congress Gold Mine Project (Arizona, USA) - Advanced exploration and development targeting gold, silver, and copper mineralization
Arsenault Gold-Copper Project (British Columbia, Canada) - Copper-gold-silver exploration with advanced geophysical targeting
The Company's strategic positioning with projects spanning two jurisdictions provides operational flexibility to maintain active exploration programs throughout the year across multiple properties.
CONGRESS GOLD MINE PROJECT UPDATE
The Congress Gold Mine, historically one of Arizona's largest gold-silver producers, represents an advanced exploration opportunity with substantial historic production data.
Historic Resource Context:
Historic operators reported resource estimates and production figures for the Congress Gold Mine. These historic estimates are disclosed solely for context and have not been verified by a current Qualified Person. The historic estimates do not conform to current NI 43-101 standards, are not classified as current mineral resources or mineral reserves, and should not be relied upon. A qualified person has not done sufficient work to classify the historic estimates as current mineral resources or mineral reserves, and Casa is not treating the historic estimates as current mineral resources or mineral reserves.
Previous operators including Echo Bay Mines reported estimates in the range of 400,000 to 500,000 tons at grades of approximately 0.3 opt (9.33 g/t) gold in certain zones. The mine historically produced approximately 400,000 to 500,000 ounces of gold during intermittent operations through 1992.
2026 Exploration Objectives:
Casa's 2026 program at Congress aims to:
Conduct systematic drilling to bring the project and its extended potential mineralization to NI 43-101 compliant resource standards
Build upon the Company's confirmatory drill programs that have validated portions of the historic data
Define a clear pathway for rapid resource definition and project advancement
Expand exploration in priority target areas identified through compilation of historic data and recent drilling
The Company's confirmatory drilling to date, combined with extensive historic data compilation, has established a framework for systematic resource delineation in accordance with modern standards.
ARSENAULT PROJECT UPDATE
The Arsenault copper-gold-silver project in northern British Columbia has advanced significantly following the completion of a state-of-the-art 3D Induced Polarization (IP) geophysical survey in 2025.
2025 3D IP Survey Results:
The recently completed 3D ground-based IP survey has generated compelling geophysical signatures that management, with extensive experience in similar geological settings, considers highly prospective. Key highlights include:
Significant chargeability anomalies indicating potential sulphide mineralization
Three-dimensional geophysical signatures with substantial scale and continuity
Strong correlation with previous airborne electromagnetic survey results from 2017
Multiple high-priority drill targets identified
The IP survey covered approximately 12 square kilometers with 60 km of survey lines utilizing high-density data acquisition with state-of-the-art instrumentation.
2026 Exploration Plans:
Detailed exploration planning is underway for both properties. The Company anticipates releasing comprehensive technical details and specific program parameters for the Congress and Arsenault projects in follow-up news releases as planning is finalized.
MANAGEMENT COMMENTARY
"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 CEO. "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."
