FOREMOST CLEAN ENERGY TO DEPLOY DISTRICT-SCALE MOBILEMT(TM) SURVEY OVER ITS GR AND BLACKWING URANIUM PROPERTIES

Foremost Clean Energy Ltd. plans to initiate a district-scale, 5,000-line-kilometre MobileMT airborne geophysical survey across its GR and 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 northwestern side the Athabasca basin and are strategically situated along two major structural corridors known to control uranium mineralization. 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 centre 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 chief executive officer 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 two kilometres, 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: approximately 5,000 line kilometres across both properties;
• Line spacing: 200 metres; tie lines spaced at 2,000 metres;
• Depth penetration: one to two kilometres using natural EM (electromagnetic) fields (AFMAG);
• Instrumentation: MobileMT system with high-sensitivity magnetic and VLF (very-low-frequency) sensors.

This airborne program represents a major step in Foremost's goal of advancing its northwestern 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. This equity grant represents the company's 2025 annual equity incentive issuance and is aligned with its long-term compensation philosophy, aimed at attracting, retaining and rewarding high-performing individuals while aligning their interests with those of shareholders.

The RSUs will vest in three equal instalments on April 1, 2026, April 1, 2027, and April 1, 2028, contingent on continued service and in accordance with Foremost's stock incentive plan, which was adopted by shareholders at the company's annual general and special meeting held on Dec. 20, 2025. The RSUs were granted in accordance with the plan, and the policies of the Canadian Securities Exchange and the Nasdaq Stock Market.

Qualified person

The technical content of this news release has been reviewed and approved by Cameron MacKay, PGeo, vice-president of exploration for Foremost, and a qualified person under National Instrument 43-101, who has prepared and reviewed the content of this news release.

A qualified person has not performed sufficient work or data verification to validate the historical results in accordance with National Instrument 43-101. Although the historical results may not be reliable, the company nevertheless believes that they provide an indication of the property's potential and are relevant for any future exploration program.

About Foremost Clean Energy Ltd.

Foremost Clean is a rapidly growing North American uranium and lithium exploration company. The company holds an option to earn up to a 70-per-cent interest in 10 prospective uranium properties (with the exception of the Hatchet Lake, where Foremost is able to earn up to 51 per cent), 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-plus acres in Manitoba and Quebec.
