(TSXV: CASA) (OTCQB: CASXF) (FSE: 0CM) (the \"Company\" or \"Casa\") is pleased to announce that it has received partial results from the 3D ground-based Induced Polarization (\"IP\") survey recently completed at its highly prospective copper-silver-lead-zinc Arsenault property located in northern British Columbia, close to the Yukon-B.C. border. The geophysical contractor employed state-of-the-art instruments with dipoles at 100m station spacing to dimensions of 15m in subsurface high density data acquisition. The survey consists of 60 km of parallel lines with 200m line spacing that covered approximately 12 square kms at the heart of the 96.5 square kilometer (37.3 sq. mile) Arsenault property. The property is located in \"Big Salmon\" geological terrain comprising volcano-sedimentary formations that elsewhere are host to important VMS and precious metals deposits. Data acquired in the field is now being processed to present two dimensional drawings (pseudo-sections) that depict ground mass resistivity and chargeability and are being received daily. Survey lines are spaced at 200 metres and controlled by GPS. Figures 1 to 6 illustrate the resulting Induced Polarization and Resistivity that are interpreted to reflect characteristics of the underlying bedrock. In addition to the recent survey and other work by its own crews, Casa has a large database of similar geophysical work, geochemical surveys, geological mapping, and trenching. An airborne VTEM survey in 2017 revealed five compelling exploration targets of low resistivity coincident with strong geochemistry in volcanic members of Big Salmon rocks. As shown in the accompanying drawings, the 2025 advanced 3D ground IP survey is highlighted by strong geophysical signatures that confirm most of the pre-existing data including that from a previously flown Airborne Electromagnetic (\"EM\") survey (2017). The colour-coded pseudo-sections show a pattern of high to very high chargeability responses as well as an array of resistivity responses from very low to high but due in part to widely varying electrical characteristics inherent in different rock and mineral types, do not allow confident assignment of anomalies to ...
