Foremost Clean Energy Completes Highly Successful Exploration Drill Program at Hatchet Uranium Property and Provides Corporate Update
Highlights include:
- Anomalous radioactivity was detected in 6 out of 10 completed drill holes, assay results are pending
- At Tuning Fork, identification of an extensive hydrothermal system, strong alteration halo, and anomalous radioactivity surrounding drill hole TF-25-16
- At Richardson, uranium mineralization was extended 50-metres along the Richardson conductor in drill hole RL-25-32 confirming system’s growth potential
VANCOUVER, British Columbia, May 15, 2025 (GLOBE NEWSWIRE) -- Foremost Clean Energy Ltd. (NASDAQ: FMST) (CSE: FAT) (“Foremost” or the “Company”) completed a highly successful maiden winter drill program at the Hatchet Lake Uranium Property ( "Hatchet "), which is located in the world-renowned Athabasca Basin region of northern Saskatchewan (Figure 1). The diamond drill program, originally planned as an 8-hole ~2,000 metre program, increased to 10-holes for over 2,400 metres following positive preliminary results from drill hole TF-25-16 – which discovered a new area of uranium mineralization highlighted by a mineralized interval of 0.10% eU3O8 over 6.5m, including 0.22% eU3O8 over 0.9m, within a 15m wide zone of alteration. Anomalous radioactivity was detected directly above and/or below the unconformity in six of the ten drill holes completed as part of the drill program: RL-25-32, TF-25-13, TF-25-16, TF-25-17, TF-25-18, and TF-25-19. Samples from the mineralized intersections in these drill holes have been submitted for assay and results are pending.
A notable highlight from the completion of the drill program was the 50 metre extension of previous mineralization along the Richardson conductor with drill hole RL-25-32, which returned two discrete mineralized intervals, as summarized in Table 1.

Jason Barnard, Foremost’s President and CEO commented, “Our immediate success at Hatchet is attributable to Foremost’s unique collaboration with Denison Mines Corp. (“Denison”), where Denison’s extensive historic work on the property has identified several prospective structural settings for the potential discovery of uranium mineralization. We are particularly excited about the result from drill hole TF-25-16, which was the first hole completed in a 600-meter gap in an under-explored target area, resulting in the discovery of a new area of uranium mineralized. Based on follow up drilling in this area we are seeing strong radioactivity within graphitic shear zones, classic Athabasca-style clay alteration, and evidence of multiple mineralization events – making this an exciting new discovery with many of thehallmarks of a high-grade unconformity system that is open in every direction.”
“For our shareholders, these results validate our strategy and speak to the potential of Foremost’s ten uranium exploration properties under option from Denison: leveraging our strategic collaboration with Denison to make high-impact discoveries in one of the world 's premier uranium districts. As we await assays from Hatchet and plan further follow-up drilling, we 're equally excited to be able to apply the same exploration model across our portfolio, including expected upcoming drill programs at CLK and Murphy Lake South.”

Tuning Fork
Figure 2 – Tuning Fork Claim Block - 2025 drill hole locations and historical results.
Two drill holes were completed for initial follow up of the mineralization discovered in TF-25-16 – with TF-25-17 & TF-25-18 drilled off the same pad location as TF-25-16 and designed to examine the up-dip and down-dip extension of the mineralization intersected in TF-25-16. Two additional drill holes, TF-25-19 & TF-25-20, were completed to target the conductor axis 40-metres and 60-metres NE and SW, respectively, to test the along strike extension of the mineralization encountered in TF-25-16 (Figure 2). Extensive hydrothermal alteration (clay, hematite, and chlorite) was encountered with elevated radioactivity near the unconformity in each of the follow up drill holes, except for TF-25-20. These alteration markers are potentially indicative of a significant hydrothermal system, and when combined with confirmed uranium mineralization near major structural boundaries, represent one of the most reliable indicators of a high-potential area for follow-up.
Richardson
Figure 3 – Richardson Claim Block - 2025 drill hole locations and historical results.
The mineralization discovered in RL-25-32, at an approximate depth of 90 metres, is interpreted to be an extension of the mineralization intersected by RL-24-29 in 2024 (Figure 3). The second mineralized interval in RL-25-32, intersected mineralization at a depth of approximately 240 metres, which represents a new horizon for mineralization on the Richardson conductor, as previous drilling was generally aimed at shallow targets. Overall, the confirmation of mineralization along strike and the discovery of a new mineralized interval at depth is highly encouraging for the Richardson trend and suggests that there may be potential to discover additional mineralization along trend at depth, which is largely untested by historical drilling. Numerous additional target locations have been identified on the Richardson trend and warrant future drill testing.
Samples from drill core were collected during the drill program and shipped to SRC Geoanalytical Labs (“SRC”) and all applicable Portable Infrared Mineral Analyzer (“PIMA”) samples have been shipped to Rekasa Rocks Inc. to analyze and determine clay species. Assays are currently undergoing analysis and will be announced by news release upon completion, expected in the coming weeks.
Planned Follow-Up Exploration at Hatchet Lake
Work in 2025 will focus on integrating newly acquired geochemical, structural, and geological data to refine vectors toward the potential source of the recently discovered mineralization. Ground geophysics is currently being evaluated to help de-risk future drilling by delineating key structures and alteration zones identified in the latest campaign.
A winter 2025–2026 drill program is being planned to test newly defined anomalies and advance the geological understanding of the mineralization intersected in drillhole TF-25-16. Conducting the program during the winter season will enable drilling of high priority targets accessible by drilling from frozen lake surfaces. Additional follow-up exploration is scheduled across the broader Hatchet Lake property during this period, positioning the project for its next phase of discovery and development.
Technical Advisor Appointment
Foremost is pleased to report the appointment of Chad Sorba, Denison’s Vice President of Technical Services & Project Evaluation, as Technical Advisor to the Company pursuant to the transaction announced with Denison in 2024. Mr. Sorba is a Professional Geologist (P. Geo) with nearly two decades of experience in Canadian and international uranium exploration, evaluation, and development, and serves as Denison’s Qualified Person pursuant to NI 43-101.

Mr. Sorba is a key technical leader of the Denison team that is pioneering the use of the In-Situ Recovery (“ISR”) mining method at certain high-grade uranium deposits in Saskatchewan, including involvement in the design and implementation of the first-of-its-kind ISR feasibility field test, which was successfully completed at Denison’s Phoenix deposit. He was a critical member of the discovery team for both of Denison’s Phoenix and Gryphon uranium deposits and brings a wealth of Athabasca-focused expertise in uranium exploration to Foremost.
Mr. Sorba’s advisory role reinforces Foremost’s commitment to technical excellence, disciplined project development, and value-driven growth in the uranium sector. This collaboration aligns with the Company’s strategy to leverage world-class expertise as it progresses its exploration and development objectives.
Sampling, Analytical Methods and QA/QC Protocols
Following the completion of a drill hole, the hole is radiometrically logged using a downhole gamma probe, which collects readings of radioactivity every 0.1m along the length of the drill hole. Probe results are then calibrated using an algorithm calculated from the comparison of probe results against a geochemical reference. The gamma-log results provide an immediate radiometric equivalent uranium value (eU3O8%) for the hole, which, except in very high-grade zones, is reasonably accurate.
The downhole gamma probe data detailed in this news release was measured using a QL40-GR Natural Gamma probe from Mount Sopris that was calibrated on February 27, 2025, at the Grand Junction, CO, calibration test pits. Downhole measurements were taken at 0.10m intervals from the top of hole and depth corrected to the handheld RS-125 scintillometer, which was used to determine radioactivity of the core. Final depth measurements and true thickness have not yet been determined.
Where core has been recovered, sampling over mineralized interval is standardized 0.5m samples, except over intervals of strongly elevated radioactivity where select samples between 0.10 & 0.25m were collected. This includes shoulder samples 1m above and below the elevated zone. These select samples were split in half, with one kept in the core box and the other shipped to SRC for sample preparation and analysis. SRC is an independent laboratory with ISO/IEC 17025: 2005 accreditation for the relevant procedures. Control samples are implemented at a frequency of ~5%.
PIMA samples were taken systematically every 10m with increased sample density around strong alteration. Samples were dried and placed into Ziplock bags in preparation for shipping to Rekasa Rocks Inc. PIMA samples are used to identify the different clay species present in the sample to identify clay minerals that can assist in the identification of a potential hydrothermal source.
