Insights

Senior Mineral Exploration Analyst

Shallow, high-grade gold intercepts confirm and expand the Jean Lake mineralized footprint; follow-up assays and step-outs will define scale.

Foremost Clean Energy reports multiple near-surface gold intercepts from the 2025 program, including a highlighted 34.2 g/t Au over 0.8 m within 9.0 g/t Au over 3.5 m in hole JL25-003. All reported significant intervals occur within 100% of surface depth as stated, and the company plans continued step-out drilling and initial lithium pegmatite testing on the property.

The business mechanism is straightforward: confirming repeated, shallow high-grade gold intercepts increases the technical case for a contiguous mineralized system along the Valkyrie Trend and helps prioritize near-term drilling targets. Key dependencies and risks are explicit in the release: the results are downhole lengths with true thicknesses not yet determined, additional assays are pending, and historical results lack full NI 43-101 verification. Monitor assay returns from remaining holes, step-out results that demonstrate lateral continuity beyond the initial footprint, and results from the lithium pegmatite tests over the next phase of the 2025 program as the nearest-term milestones to clarify scale and continuity within months to a year.

Drilling Confirms High-Grade Gold System, Extending Mineralization Along the Valkyrie Trend

VANCOUVER, British Columbia, Nov. 19, 2025 (GLOBE NEWSWIRE) -- Foremost Clean Energy Ltd. (NASDAQ: FMST) (CSE: FAT) ("Foremost" or the "Company"), is pleased to announce the receipt of assay results for drillholes JL25-003 and JL25-004 from its ongoing 2025 drill program at its 100%-owned Jean Lake Gold-Lithium Property (“Jean Lake”) located near the historic mining centre of Snow Lake in Manitoba. The 2025 drill program represents a critical step in advancing the high-grade gold discovery first made at Jean Lake in 2023. The progression of results demonstrates a consistent and expanding mineralized system. The Company is reporting multiple gold intercepts from drill holes JL25-003 and JL25-004 along the Valkyrie Trend (Figure 1). These results along with previous intercepts from drill hole FM23-08, drillholes JL25-01, and JL25-02 all occur at depths within 100m from surface (Figure 2) highlighting the potential for more near-surface gold along this emerging gold-bearing trend.

Highlights:

JL25-003

• 34.2 g/t Au over 0.8m included within 9.0 g/t Au over 3.5m starting at 127.8 m
• 9.7g/t Au over 0.5 m included within 2.7 g/t Au over 2.6m starting at 89.1 m
• 6.2 g/t Au over 1.0 m included within 1.81 g/t Au over 7.0m starting at 104.5 m
  

JL25-004

• 6.6 g/t Au over 0.7m within 2.7 g/t Au over 1.6m starting at 101.7 m
• 5.4 g/t Au over 0.5m within 3.2 g/t Au over 1.5m starting at 90.0 m
• 3.3 g/t Au over 0.5m included within 1.3 g/t Au over 1.5m starting at 87.0 m
  

Jason Barnard, Foremost’s President and CEO, commented: “We are increasingly encouraged by what we are seeing at Jean Lake. Each stage of drilling, first in 2023 and now through the initial holes of the 2025 program, continues to confirm a shallow, high-grade gold system along the Valkyrie Trend. The consistency of the mineralization near surface is exactly what we hoped to see at this early stage. With step-outs underway, and additional assays pending, we are beginning to gain a clearer picture of the scale and continuity of this emerging gold system.

These latest results highlighted by 34.2 g/t over 0.8 metres within 9.0 g/t over 3.5 metres in JL25-003 underscore the strength of the Jean Lake project. What really sets these results apart is the consistently shallow depths. Discovering this calibre of gold mineralization less than 100 metres from surface is highly advantageous for ongoing exploration and significantly enhances our confidence in exploring this gold mineralized system.

With gold markets remaining exceptionally strong, we believe Jean Lake is emerging at exactly the right moment. The combination of shallow high-grade results and a supportive macro environment positions the project as a compelling value driver for our shareholders.”

2025 Jean Lake Drill Program Summary

The objective of the 2025 program was to test the scale and continuity of the Jean Lake gold discovery and to delineate the near-surface, spodumene-bearing B1 Pegmatite. The results have successfully confirmed a larger mineralized footprint:

• Drill holes JL25-001 and JL25-002 extended mineralization beyond the initial discovery area, returning high-grade intercepts such as 40 g/t Au over 0.6 m included within 12.7 g/t Au over 2.07 m and 82 g/t Au over 0.7 m included within 10.7 g/t Au over 5.6 m (see news release November 10, 2025).
• Drill holes JL25-003 and JL25-004 have further confirmed the system’s additional high-grade intervals and demonstrating consistent mineralization in the discovery area.

These results, together with the 2023 intercept in drill hole FM23-08 of 102 g/t Au over 0.48 m within 7.50 g/t Au over 7.66 m, (see news release June 06, 2023) all occur within 100 m of surface (Figure 2) and collectively represent the discovery of a near-surface mineralized system along the Valkyrie Trend. Assay results for drill holes JL25-003 and JL25-004 are found in Table 1.

Next Steps

The results from the first four holes are a strong validation of Foremost’s exploration model. As the Company continues to advance its 2025 program, drilling will be focused on further step-outs along the Valkyrie Trend and initial testing of lithium-bearing pegmatite targets. Assay results for these additional holes are pending.

The progression of positive drilling results beginning in 2023, highlights the potential of the Valkyrie Trend on the Jean Lake Project and provides a clear basis for continued follow-up work.

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.
