FOREMOST CLEAN ENERGY TO CONDUCT AIRBORNE GEOPHYSICS SURVEY OVER ITS CLK URANIUM PROPERTY

Foremost Clean Energy Ltd. has engaged Expert Geophysics Surveys Inc. (EGS) to conduct a 771-line-kilometre MobileMT airborne geophysical survey over its CLK uranium property, situated in Athabasca basin region in Northern Saskatchewan. The survey is expected to enhance the company's understanding of the conductive trends prospective for uranium mineralization, which were targeted during the 1997 drilling campaign that encountered uranium mineralization at 862 metres depth. Previous targeting was based on outdated geophysical surveying methods, which could not achieve the high resolution of subsurface mapping that is available from modern geophysical surveying systems.

Jason Barnard, Foremost's president and chief executive officer, noted: "The 1997 drill results at CLK identified uranium mineralization at what were considered exceptional depths for that era. Modern geophysical systems like MobileMT finally give us the tools to properly evaluate conductive trends at this depth. The survey is expected to help identify deep basement conductors that may highlight structural extensions associated with the mineralization or new target areas."

The MobileMT system was selected for its ability to map subsurface conductivity variations to depths of one to two kilometres, making it particularly well suited for evaluating CLK's demonstrated potential for deep mineralization. Historical drilling at CLK intersected pitchblende (uranium oxide) and graphite at over 800 metres vertical depth, confirming the presence of conductivity at depth, which has potential to be associated with a mineralizing system.

Key technical highlights of MobileMT for uranium exploration include:

• One-to-two-kilometre depth penetration -- detects deep basement conductors and highlights structural breaks, vital exploration criteria of known major deposits;
• Multifrequency EM (electromagnetic) system -- measures 25-hertz-to-20,000-hertz signals to resolve conductive anomalies up to two kilometres below surface;
• Integrated magnetics -- simultaneous high-sensitivity (0.001 nanotesla) magnetic surveying;
• Proven in uranium exploration -- successfully maps deep faults, conductors and alteration halos in Athabasca-style systems;
• Targets extensions -- ideal for generating targets to expand existing mineralization and explore other attractive areas on the property;
• Operational efficiency -- digital data available for preliminary interpretation within 24 hours of acquisition.

The CLK property comprises 25,753 acres (10,422 hectares), located approximately 30 kilometres south of the Athabasca basin margin. The property lies within the Snowbird tectonic zone, a structural corridor that hosts several uranium occurrences. The 1997 and 2000 drilling programs at CLK resulted in the completion of two significant drill holes, CLG-D1 and CLG-D5, both of which intersected notable uranium mineralization:

• CLG-D1 -- intersected 8,600 parts per million uranium at 862 metres, hosted in pitchblende stringers in the basement just below the unconformity;
• CLG-D5 -- intersected 510 parts per million uranium at approximately 900 metres depth immediately above the unconformity.

The coming MobileMT survey is intended to provide the first comprehensive geophysical coverage of the property at appropriate depth resolution. Data collection is scheduled to begin in late April or early May, 2025, with final processed results expected by July, 2025. The survey results are expected to guide a planned 2,000-metre diamond drilling program anticipated to begin in the third quarter of 2025.

The use of similar deep-penetrating geophysical methods in the Athabasca basin have supported the discovery or delineation of significant uranium deposits (including Cameco's McArthur River deposit), which occur at depths of several hundred metres. The company believes CLK represents a potentially similar and prospective target that is underexplored.

Foremost has the option to acquire up to a 70-per-cent interest in the CLK property from Denison Mines Corp. under the terms of an option agreement entered into in 2024 (see news release dated Sept. 24, 2024).

About Foremost Clean Energy Ltd.

Foremost Clean Energy 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 more than 55,000 acres in Manitoba and Quebec.
