DISCOVERY ENERGY METALS CORP. ANNOUNCES COMPLETION OF GEOCHEMICAL SAMPLING PROGRAM AT CRYSTAL LAKE CU-MO PROJECT, BRITISH COLUMBIA

Discovery Energy Metals Corp. has successfully concluded its surface prospecting and geochemical soil sampling program on its Crystal Lake property. The property is located approximately 160 kilometres southwest of Prince George, B.C., and is highly prospective for porphyry-style copper and molybdenum mineralization.

Program highlights:

• Soil sampling: The company collected a total of 280 B-horizon soil samples over two grids along the eastern side of Crystal Lake. Samples were collected at 25-metre intervals along northeast-southwest-oriented lines spaced 50 metres apart. The soil grids targeted historically identified surface mineralization and geophysical anomalies on the property.
• Rock sampling: Twenty-five outcrop samples were collected opportunistically across soil sampling grids when bedrock exposure permitted.

The surface sampling program was completed by Dahrouge Geological Consulting over a period of eight days between May 23 and May 30, 2026. The field program was based out of Crystal Lake Resort, located directly within the property boundary. The results, when received, will be utilized to guide future exploration on the property,

Quality assurance/quality control

All rock samples were collected in the field using a hammer and chisel. Soil samples were collected from the presumed B horizon using a hand auger and/or geotool. Locations for all sample types were obtained using a hand-held GPS (Global Positioning System) or tablet with samples placed in prelabelled sample bags. Samples were securely shipped using Manitoulin Transport to Agat Laboratories Ltd. in Calgary, Alta., for preparation and geochemical analysis. Due to the preliminary nature of the program, no certified reference materials, blanks or field duplicates were inserted into the sample stream. The company will rely on the internal quality assurance and quality control procedures of Agat Laboratories, which is accredited to ISO/IEC 17025:2017. Specific preparation and analytical methods will be disclosed with assay results.
