VANCOUVER, British Columbia, Feb. 26, 2026 (GLOBE NEWSWIRE) -- Foremost Clean Energy Ltd. (NASDAQ: FMST) (CSE: FAT) ("Foremost" or the "Company") is pleased to report results from its targeted historic core resampling program at its 100%-owned Jean Lake Gold-Lithium Property ("Jean Lake"), located near the historic mining centre of Snow Lake in Manitoba. This program was completed following the Company's December 2025 diamond drill campaign and focused on resampling previously unsampled intervals from select 2023 drillholes along the Valkyrie and Midas Gold Trends (see News Release dated December 8, 2025). Highlights include:
- FM23-25: 1.10 g/t Au over 8.0 metres from 22.0-30.0m, including 6.9 g/t Au over 0.5 metres
- FM23-08: 0.64 g/t Au over 10 metres from106.5-116.9m
The objective of this work was to address underrepresented sampling in certain mineralized sections, improve continuity interpretation between previously reported intercepts, and refine the Company's understanding of gold distribution within the broader structural corridor.
Jason Barnard, Foremost's President commented: "This targeted resampling program was designed to address previously unsampled intervals within mineralized sections and improve the representation of gold distribution within historical drill core. Systematic sampling of previously unassayed intervals has identified additional mineralized sections and provides a more complete representation of gold distribution within the Valkyrie structural corridor. These results support refinement of the geological interpretation and will inform step-out and infill drill targeting in the next phase of exploration at Jean Lake."

Integrated Results Summary
The results presented here include both previously reported gold intercepts from the Company's 2023 drill program (see News Release dated June 6, 2023) and new assay results generated from the Company's 2025 gap-fill re-sampling program. The additional assays demonstrate that mineralization extends beyond previously reported intercepts and occurs through intervals that had not been systematically sampled. The integration of these results provides a more complete representation of gold distribution within the drilled sections and supports ongoing refinement of the structural and geological model along the Valkyrie Gold Trend. See Table 1 below for a summary of significant intercepts from the 2023 drill program and the 2025 resampling program.

Next Steps
The Company will integrate the new gap-fill assay results from the 2023 drill core with the recently announced 2025 drill program results (see news release dated February 25, 2026). Together, these datasets provide a more comprehensive understanding of gold distribution along the Valkyrie Trend, which has now been traced over approximately 600 metres of strike length. This updated interpretation will be used to refine geological and structural models, with a focus on:
- Defining mineralized envelopes within the historically drilled corridor;
- Targeting higher-grade zones hosted within broader low-grade envelopes;
- Prioritizing follow-up drill holes to test continuity along strike and at depth.
The integration of resampled intervals with 2025 drill results will assist with next phase of exploration, which is expected to include both step-out and infill drilling aimed at expanding the mineralized footprint and advancing the Valkyrie Trend.
Sampling, Analytical Methods and QA/QC
All drill core samples from the Jean Lake gold drilling program were collected as NQ-sized core. In zones of visible quartz-veining, sericite alteration, and arsenopyrite mineralization, samples were typically taken at 50 cm intervals. Outside of these zones, holes were continuously sampled at 1.5 m intervals. All core was sawn longitudinally, with one half retained on site for reference and the other half submitted for analysis. Samples were shipped to SGS Canada Inc., Burnaby, British Columbia, for sample preparation and analysis. At SGS, samples were dried at 105°C, crushed to 75% passing 2 mm, and pulverized to 85% passing 75 microns (method PRP89). Gold analyses were performed by 30 g Fire Assay with Atomic Absorption Spectrometry finish (method GE_FAA30V5) with a detection range of 5-10,000 ppb Au. Samples returning values above the upper detection limit were re-assayed by 30 g Fire Assay with Gravimetric finish (method GO_FAG30V) with a reporting range of 0.5-10,000 ppm Au. Multi-element geochemical analyses were completed using the 57-element sodium peroxide fusion ICP-AES/ICP-MS package (method GE_ICM91A50), which provides detection limits suitable for trace-level pathfinder elements such as As, Sb, and W relevant to gold mineralization. Analytical work was performed at SGS's ISO/IEC 17025-accredited facilities, which operate under strict internal QA/QC protocols.
Quality control procedures at SGS include the routine insertion of blanks, certified reference materials (standards), and duplicates at a minimum frequency of 11-12% of all analyses, depending on method and grade classification. Laboratory quality is monitored through SGS's SLIM Laboratory Information Management System, which automatically flags data exceeding internal precision or accuracy thresholds and triggers reanalysis when necessary. Foremost's internal QA/QC protocol includes the insertion of field duplicates, certified standards, and blanks into the sample stream at regular intervals to independently monitor analytical precision and contamination. All reported intervals represent downhole lengths, and true thicknesses have not yet been determined.
