Aggressive Exploration Plans For Congress Gold Mine

VANCOUVER – Casa Minerals Inc. announced plans for an expanded exploration program in 2026 across its mineral properties in Arizona, and British Columbia. In response to strengthening global demand for resources and commodities, Casa is advancing aggressive exploration and development plans for its key mineral assets: 1) Congress Gold Mine Project (Arizona, USA) – Advanced exploration and development targeting gold, silver, and copper mineralization. 2) 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.
The Congress Gold Mine, historically one of Arizona’s largest gold-silver producers, represents an advanced exploration opportunity with substantial historic production data. 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.
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. 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. 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.
