VANCOUVER, BC / ACCESS Newswire / June 16, 2026 / Discovery Energy Metals Corp. (CSE:DEMC)(OTCQB:DEMCF)(FRA:Q3Q0)(WKN:A3EFKA) ("Discovery" or the "Company"), a Canadian exploration company focused on advancing mineral resource projects in North America, is pleased to announce that it has successfully concluded its surface prospecting and geochemical soil sampling program on it's Crystal Lake Property (the "Property"). The Property is located approximately 160 km southwest of Prince George, British Columbia, and is highly prospective for porphyry-style copper and molybdenum mineralization.

Program Highlights:

• Soil Sampling: Collected a total of 280 B-horizon soil samples over two grids along the eastern side of Crystal Lake. Samples were collected at 25 m intervals along NE-SW oriented lines spaced 50 m apart. The soil grids targeted historically identified surface mineralization and geophysical anomalies on the Property.

• Rock Sampling: Twenty-five (25) 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 (8) 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 handheld GPS or tablet with samples placed in pre-labelled sample bags. Samples were securely shipped using Manitoulin Transport to AGAT Laboratories Ltd. in Calgary, AB 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 Ltd., which is accredited to ISO/IEC 17025:2017. Specific preparation and analytical methods will be disclosed with assay results.
