Foremost Clean Energy to Deploy District-Scale MobileMT™ Survey Over its GR and Blackwing Uranium Properties

VANCOUVER, July 07, 2025 - Foremost Clean Energy Ltd.. (NASDAQ: FMST) (CSE: FAT) ("Foremost" or the "Company"), is pleased to announce plans to initiate a district-scale 5,000 line-kilometer MobileMT™ airborne geophysical survey across its GR ("GR") and Blackwing ("Blackwing") Uranium Properties, located in the world-renowned Athabasca Basin region of northern Saskatchewan. The survey, to be conducted by Expert Geophysics Surveys Inc, is designed to detect deep conductive structures prospective for hosting high-grade uranium mineralization. The program is expected to begin mid-July, subject to operational scheduling.

GR and Blackwing are located on the north-western side the Athabasca Basin and are strategically situated along two major structural corridors known to control uranium mineralization (see Figure 1). The Grease River Shear Zone, which bisects GR, is a major crustal-scale fault system that has been interpreted as a conduit for mineralizing fluids. Similarly, the Black Bay Fault, which cuts directly through the center of Blackwing, is a prominent reactivated basement structure that may provide an ideal setting for the concentration of uranium-bearing fluids.

Jason Barnard, President and CEO of Foremost, commented: "Our team is excited to apply cutting-edge MobileMT technology to these highly prospective but underexplored projects. The scale of this survey reflects our belief in the untapped potential of the GR and Blackwing properties. With large, uranium-fertile structures like the Grease River Shear Zone and Black Bay Fault running through these claims, the opportunity for meaningful discovery is compelling. This is the first time these areas will be systematically evaluated using a deep-penetrating geophysical tool like MobileMT, and we look forward to the insights it will provide."

The MobileMT™ system offers a unique advantage by imaging subsurface resistivity to depths of up to 2 kilometers, making it particularly effective at mapping deep basement conductors and structural features that are often associated with high-grade Athabasca-style uranium deposits.

Key Technical Highlights of the GR and Blackwing Survey:

• Survey Size: ~5,000 line-km across both properties
• Line Spacing: 200 meters; Tie lines spaced at 2,000 meters
• Depth Penetration: 1-2 km using natural EM fields (AFMAG)
• Instrumentation: MobileMT™ system with high-sensitivity magnetic and VLF sensors

This airborne program represents a major step in Foremost's goal of advancing its north-western Saskatchewan uranium portfolio through modern, efficient exploration methods. The results are expected to provide essential data to guide future ground programs and drill targeting on both properties.

The GR and Blackwing properties both hosts compelling structural features that lie within a regional-scale fault zone with demonstrated mineralizing potential in an area that has remained largely unexplored. The Company believes both properties represent frontier opportunities for the discovery of new high-grade uranium systems and looks forward to reporting results from the planned geophysical surveying.

Annual Equity Grant

As part of its regular annual compensation review process, Foremost has approved the issuance of 413,100 Restricted Stock Units ("RSUs") to its management team, board of directors, employees, consultants, and staff, subject to approval by the Canadian Securities Exchange ("CSE").

About Foremost

Foremost Clean Energy Ltd. (NASDAQ: FMST) (CSE: FAT) (WKN: A3DCC8) is a rapidly growing North American uranium and lithium exploration company. The Company holds an option to earn up to a 70% interest in 10 prospective uranium properties (with the exception of the Hatchet Lake, where Foremost is able to earn up to 51%), spanning over 330,000 acres in the prolific, uranium-rich Athabasca Basin region of northern Saskatchewan. As the demand for carbon-free energy continues to accelerate, domestically mined uranium and lithium are poised for dynamic growth, playing an important role in the future of clean energy. Foremost's uranium projects are at different stages of exploration, from grassroots to those with significant historical exploration and drill-ready targets. The Company's mission is to make significant discoveries alongside and in collaboration with Denison through systematic and disciplined exploration programs.

Foremost also has a portfolio of lithium projects at varying stages of development, which are located across 55,000+ acres in Manitoba and Quebec. For further information, please visit the Company's website at www.foremostcleanenergy.com.
