FOREMOST CLEAN ENERGY ANNOUNCES THE SUCCESSFUL COMPLETION OF AIRBORNE GEOPHYSICAL SURVEY OVER ITS CLK URANIUM PROPERTY

Foremost Clean Energy Ltd. has successfully completed an airborne geophysical survey over the CLK uranium property, which is located in the world-renowned Athabasca basin region of Northern Saskatchewan. Expert Geophysics Surveys Inc. (EGS) completed 771 line kilometres (km) of electromagnetic surveying using its mobile magnetotellurics (MobileMT) system and is currently processing the survey data to identify conductive trends and structural features associated with known uranium mineralization. The company anticipates receiving the interpreted results in the coming weeks, which will then be used to delineate targets for the upcoming summer, 2025, drill program.

"The completion of this high-resolution geophysical survey marks another important step in advancing our pipeline of drill targets on Foremost's unique portfolio of properties optioned from Denison Mines. The CLK property is another highly prospective, underexplored asset we believe holds significant potential given the presence of multiple notable historical mineralized drill holes," states Jason Barnard, president and chief executive officer of Foremost Clean Energy. "The MobileMT system provide us unparalleled clarity in mapping subsurface conductors, which will help prioritize targets, including extensions of known mineralization like the 8,600 ppm U intersection in hole CLG-D1 (1997), and identify new anomalies. With no modern systematic drilling across most of the property, we believe CLK holds significant discovery potential that this survey will help unlock compelling targets for additional follow-up for our upcoming summer drill program."

The CLK property comprises two claims, over 25,753 acres/10,422 hectares, located approximately 30 km south of the northern edge of the Athabasca basin. The CLK project lands capture a portion of the northeastern edge of the Snowbird tectonic zone, known to host several uranium occurrences. The 1997 and 2000 drilling program 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 (ppm) uranium (U) at 862 metres (m), hosted in pitchblende stringers in the basement just below the unconformity;
• CLG-D5: intersected 510 ppm U at approximately 900 m depth immediately above the unconformity.

Summer, 2025, drill program

With known uranium mineralization hosted at and below the unconformity, the CLK property is a high-priority project in Foremost's project discovery pipeline. The results from this geophysical survey will be integrated with existing geological data to refine targets for a planned 2,000 m diamond drill program anticipated to commence later this summer.

The primary focus of the drill program will be testing extensions of these historical intersections and any newly identified conductive anomalies interpreted from the survey. The use of deep-penetrating geophysical methods in the Athabasca basin is a relatively recent development that has the potential to identify high-priority drill targets on untested conductive trends, which may be associated with significant uranium deposits. The company believes CLK has the potential to host multiple prospective and unexplored drill targets that may be identified through modern geophysics.

About Foremost Clean Energy Ltd.

Foremost 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.
