Foremost Clean Energy Announces Upcoming Ground-Based Gravity Survey at its Hatchet Lake Uranium Project, Athabasca Basin, Saskatchewan

14:30 Uhr  |  GlobeNewswire

VANCOUVER, Dec. 04, 2025 - Foremost Clean Energy Ltd.. (NASDAQ: FMST) (CSE: FAT) ("Foremost" or the "Company"), is pleased to announce a ground-based gravity survey will commence in December over its Hatchet Lake Uranium Property ("Hatchet"), located in the eastern Athabasca Basin region ( the "Basin") of northern Saskatchewan (see figure 1). The gravity survey is focused on the southern extent of the Richardson Trend where there has been limited drilling (see figure 2). The survey will be conducted by MWH Geo Survey ("MWH"), a leading geophysical contractor with more than 40 years of experience throughout the Basin.

Foremost's President and CEO Jason Barnard commented: "The Hatchet Lake gravity survey marks an important step in refining our geological model along the Richardson Trend. By integrating gravity, electromagnetic, magnetic and geochemical data, we are building a more complete picture of the subsurface architecture that controls uranium mineralization in this area. The results are expected to directly influence our winter 2026 drill program, ensuring that our next round of drilling is focused, data-driven, and aligned with the most prospective structural targets."

Gravity Survey Details

The program is anticipated to comprise approximately 788 gravity stations collected at 100-metre station intervals on 200-metre line spacing across priority structural corridors on the southeast extension of the Richardson trend extending beyond the Athabasca Basin margin (see figure 2). These measurements will assist in refining subsurface interpretations, mapping density contrasts, and identifying potential zones of hydrothermal alteration associated with uranium-bearing structures.

Richardson Trend

The Hatchet Lake Project covers a significant portion of the Richardson Trend, a well-established basement structural corridor known to host uranium mineralization both on the property and along strike. Importantly, the southeast extension of the Richardson Trend contains more than 6 km of under-tested conductor strike length. The trend hosts brittle-ductile sheared, graphitic basement conductors, which when reactivated, serve as enhanced hydrothermal fluid pathways that create favourable conditions for the development of basement-hosted and unconformity-related uranium deposits. The structural setting is analogous to other major uranium systems along the eastern Basin margin, such as the La Rocque Corridor which is host to ISO Energy's Hurricane Deposit, and Cameco's La Rocque Lake Uranium Zone.

Historic drilling along the Richardson Trend conducted by Denison Mines Corp. ("Denison", NYSE American: DNN, TSX: DML) returned multiple uranium-bearing intervals and strong alteration consistent with a fertile mineralizing system. Significant past results include:

• 1.52% U?O? over 0.15 m in hole RL-13-13¹
• 0.45% U?O? over 2.3 m in hole RL-13-16¹

The 2025 ground gravity survey is designed to identify gravity lows and gradients associated with hydrothermal alteration halos and fault-controlled fluid pathways. Gravity anomalies that overlap with graphitic shear zones, magnetically interpreted structures, and geochemical anomalies will be prioritized for drill testing.

The company is planning for an anticipated drill program to commence in early 2026, which will focus on priority targets including those along the Richardson Trend and Tuning Fork Target Area.

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 from Denison Mines Corp. ("Denison") to earn up to 70% interest in 10 prospective uranium properties (except for the Hatchet Lake, where Foremost can 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.
