VANCOUVER, British Columbia, May 05, 2026 (GLOBE NEWSWIRE) -- Foremost Clean Energy Ltd. (NASDAQ: FMST) (CSE: FAT) (“Foremost” or the “Company”) is pleased to announce the results of a previously completed 2025 helicopter-borne MobileMT electromagnetic and magnetic survey at its 25,753-acre CLK Uranium Property (“CLK” or the “Property”), located in the northern Athabasca Basin region of Saskatchewan. The survey was conducted by Expert Geophysics Surveys Inc. and was designed to map both conductive and resistive anomalies as well as magnetic susceptibility to interpret structure, and alteration zones associated with unconformity-style uranium mineralization. Following the MobileMT survey, the Company engaged Caur Technologies Inc. to conduct an ambient noise tomography (“ANT”) survey to further refine targeting at CLK. The survey was completed in fall 2025 and the final velocity model has been received. Integration of the ANT and MobileMT datasets is now underway to define high-priority drill targets near CLG-D1, a historical drill hole that intersected 8,600 ppm U1 (approx. 1.01% U3O8) from visible pitchblende stringers just below the unconformity. Survey Highlights: The MobileMT survey covered 808 line-kilometres across the 136 km² CLK block. MobileMT results highlight a complex geo-electrical environment with conductive anomalies distributed from surface to depths exceeding 900 metres, both above and below the interpreted unconformity. The ANT survey deployed a network of 221 three-component sensors over an approximately 7.5 × 3.8 km, designed to image subsurface shear-wave velocity to depths of up to ~2 km. The ANT survey was designed to delineate the depth to the Athabasca unconformity and identify structural features such as fault zones, basement architecture, and potential alteration corridors associated with unconformity-related uranium mineralization. Jason Barnard, President and CEO of Foremost Clean Energy, commented: “The MobileMT survey has provided valuable insight into the structural framework at CLK. Now, with the ANT survey complete and the final velocity model in hand, we are integrating both datasets to advance high-priority drill targets and build on the strong foundation provided by historic high-grade uranium mineralization.” Historical Drill Highlights: CLG-D1: Intersected 8,600 ppm U1 (approx. 1.01% U3O8) at 862 meters, hosted in pitchblende stringers in the basement just below the unconformity. CLG-D5: Intersected 510 ppm U1 (approx. 0.06% U3O8) at ~ 900 meters depth immediately above the unconformity. ‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾ 1 Uranium values were obtained by XRF analysis, a legacy method that does not meet current industry standards. Samples are believed to represent single-point measurements rather than intervals. See Saskatchewan Mineral Assessment File 74J16-0013. Figure 1. CLK Uranium Property Compilation Map Mobile MT Survey Results The MobileMT survey successfully mapped a complex conductive and resistive architecture across CLK, from surface through the Athabasca sandstone and into the underlying basement (see Figure 1). Conductive responses identified through imaging within the sandstone sequence are interpreted to be associated with the Wolverine Point Formation, a known conductive unit that can obscure deeper geophysical signals. Importantly, the MobileMT system demonstrated the ability to effectively “see through” this conductive horizon, enabling the identification of deeper conductive features that may represent graphitic basement structures and associated alteration systems prospective for unconformity-related uranium mineralization. Interpretation of the frequency-dependent data highlights conductive anomalies in the 338–675 Hz range that define coherent trends within a prominent magnetic low corridor that hosts historic drilling. CLG-D1 is spatially associated with this conductive trend. CLG-D5, although not directly coincident with a modeled conductor, returned elevated uranium values and hydrothermal alteration at the unconformity. This supports the interpretation of the magnetic low as a potential fluid pathway. Outside of this corridor, conductive features are observed to locally cross-cut magnetic boundaries, suggesting a structurally complex system where conductivity is not solely controlled by magnetic domains. These results provided a strong basis for the design of the follow-up ANT survey, which was oriented to cover the historic drill holes and further refine the structural framework along this prospective trend. Next Steps With the completion of the ANT survey and receipt of the final three-dimensional seismic velocity model, the Company is currently integrating these results with the MobileMT dataset to refine the structural and geological framework at the CLK Property. This integrated interpretation is expected to support the definition of high-priority drill targets, particularly in the vicinity of the historic high-grade intersection at CLG-D1 and along prospective structural trends identified in the geophysical data. The CLK Property is fully permitted for a multi-phase exploration program, including up to 30 diamond drill holes, providing the Company with flexibility to systematically advance priority targets through future exploration programs.

Targeted Re-Sampling of Previously Unassayed 2023 Intervals Expands Understanding Of Gold Distribution Along The Valkyrie And Midas Trends 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.” Figure 1. Jean Lake – Gold Assay Results by Drillhole (2023 + 2025) 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. Table 1 – Summary of Significant Gold Intercepts (2023 Drilling + 2025 Gap-Fill Resampling) Notes: All reported assay results greater than 0.5 g/t Au are presented in Table 3. Drill holes not included did not return intervals above this threshold. Intervals are reported as downhole lengths; true widths have not yet been determined. *FM23-08 94.4–101.6m: Reflects corrected weighted-average interval 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.

2025 Drilling Identifies ~600 Metres Of Mineralized Strike Length Along the Valkyrie Gold Trend; Final Assays Include 9.4 g/t Au Over 2.2 m (Incl. 27.9 g/t Au Over 0.7 m) VANCOUVER, British Columbia, Feb. 25, 2026 (GLOBE NEWSWIRE) -- Foremost Clean Energy Ltd. (NASDAQ: FMST) (CSE: FAT) ("Foremost" or the "Company") is pleased to report the final assay results from its 2025 diamond 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 program consisted of 15 drill holes (see Figure 1) totaling 2,266 metres (see News Release dated December 8, 2025). Final assays returned high-grade near surface intercepts including 9.4 g/t Au over 2.2 metres from 48.0 metres (including 27.9 g/t Au over 0.7 metres) in JL25-010 and 6.2 g/t Au over 2.6 metres from 52.5 metres (including 31.1 g/t Au over 0.5 metres) in JL25-009 (see Table 1). These latest drill results continue to define and expand the near-surface gold system along the Valkyrie Trend. Gold mineralization has now been intersected along approximately 600 metres of strike length on and adjacent to the Valkyrie Trend (see Figure 2), significantly increasing the scale of the emerging gold system. Highlights: JL25-006 2.9 g/t Au over 6.7 m starting at 169.5 m, including 32.6 g/t Au over 0.5 m 2.6 g/t Au over 2.5 m starting at 36.0 m, including 6.2 g/t Au over 0.5 m JL25-007 2.6 g/t Au over 5.4 m starting at 43.4 m, including 6.8 g/t Au over 1.8 m JL25-009 6.2 g/t Au over 2.6 m starting at 52.5 m, including 31.1 g/t Au over 0.5 m 1.5 g/t Au over 9.1 m starting at 15.4 m, including 9.1 g/t Au over 0.9 m 1.6 g/t Au over 6.7 m starting at 30.0 m, including 9.2 g/t Au over 1.0 m JL25-010 9.4 g/t Au over 2.2 m starting at 48.0 m, including 27.9 g/t Au over 0.7 m Jason Barnard, Foremost’s President and CEO, commented: “These final results complete a successful 2025 drill campaign and significantly advance our understanding of the Jean Lake property. What began as a high-grade discovery in 2023 has now evolved into a ~600-metre mineralized gold corridor along the Valkyrie Gold Trend, characterized by consistent higher-grade zones within broader mineralized envelopes. Mineralization occurs at shallow depths in several holes and remains open along strike and at depth, reinforcing our confidence that this represents a robust shear zone gold system rather than isolated occurrences. Our next phase will focus on step-out and infill drilling to expand the corridor and further define and target the higher-grade components of this structurally controlled system.” The Valkyrie Trend – An Emerging Gold Corridor Gold mineralization at Jean Lake was first identified in discovery hole JL23-008 in 2023 (see News Release dated June 6, 2023), which returned 7.5 g/t Au over 7.66 metres including 102.0 g/t Au over 0.48 metres. Drill holes JL25-001 through JL25-004, previously reported on November 10, and 19, 2025, expanded the mineralized footprint and confirmed continuity along the Valkyrie Trend, including: JL25-001: 12.7 g/t Au over 2.07 m (including 40 g/t Au over 0.6 m) JL25-002: 10.7 g/t Au over 5.6 m (including 82 g/t Au over 0.7 m) JL25-003: 9.0 g/t Au over 3.5 m (including 34.2 g/t Au over 0.8 m) The results from holes JL25-006 through JL25-015 further extend and define gold mineralization along the Valkyrie Trend. Gold mineralization has now been identified over approximately 600 metres of strike length (Figure 2). Gold mineralization is interpreted to be primarily hosted within a steeply dipping shear zone characterized by quartz veining and sericite alteration. Mineralized intercepts are characterized by broad (~5-7m) 1–3 g/t Au mineralized envelopes hosting higher-grade zones exceeding 20–80 g/t Au. Multiple drill fences between 2023 and 2025 on and adjacent to the Valkyrie Trend illustrate a robust gold system that remains open along strike and at depth. Full assay results from the final 2025 drill holes and drill collar information are summarized in Table 1 and Table 2 below. Figure 1. Jean Lake – Gold Assay Results by Drillhole (2023 + 2025) Figure 2. Jean Lake 2025 Drillhole Location Map Showing ~600 m Structural Trend Table 1 – Summary of Significant Gold Intercepts Notes: All reported drill holes containing assay results greater than 1.0 g/t Au are presented in Table 1. Drill holes not included did not return intervals above this threshold. Intervals are reported as downhole lengths; true widths have not yet been determined. Table 2. Jean Lake 2025 Drill Hole Collar Information Notes: Collar coordinates are reported in NAD83 Zone 14. Next Steps Building on the identification of mineralization across roughly 600 metres of strike length along the Valkyrie Trend, the Company intends to advance a focused follow-up program. This program will include step-out and infill drilling to test strike extensions beyond the currently defined limits and to target higher-grade zones within the broader mineralized corridor. Work will also continue to evaluate structural controls and lithological influences on gold distribution in order to refine drill targeting and guide the next phase of exploration.

VANCOUVER, British Columbia, Jan. 14, 2026 (GLOBE NEWSWIRE) -- Foremost Clean Energy Ltd. (NASDAQ: FMST) (CSE: FAT) ("Foremost" or the "Company"), is pleased to report positive lithium assay results from its 2025 drill program at the 100%-owned Jean Lake Gold–Lithium Project (“Jean Lake”) located near Snow Lake, Manitoba. JL25-005B (see Figure 1) intersected multiple spodumene-bearing intervals within the B1 Pegmatite. These lithium results combined with structurally controlled gold mineralization reinforce the Jean Lake Property as a multi-commodity exploration play. HIGHLIGHTS: JL25-005B 1.6% Li2O over 5.0 m from 52.0m, including 2.1m of 2.8% Li2O 1.5% Li2O over 4.8m from 62.6m, including 0.8m of 2.3% Li2O The release of lithium results from JL25-005B (see Table 1) comes amid a strengthening market backdrop with lithium carbonate prices seeing a strong rally, increasing to over $20,000 USD per ton since the beginning of January, its highest level in two years.1 Jason Barnard, President and CEO of Foremost Clean Energy, commented: “These lithium results are an exciting step forward for Foremost and further demonstrate the potential of the Jean Lake Project. Intersecting 1.64% Li₂O over 5 metres confirms we are working within a fertile spodumene-bearing system and reinforces our confidence in the data-driven exploration strategy we’ve applied across the project. Recent independent research, such as Morgan Stanley’s December 2025 report, underscores a constructive outlook for core energy transition metals. The report highlights strong uranium price momentum driven by a structural supply deficit—with long-term price accretion as we head into our upcoming 2026 drill season.” Barnard continues: “Our upcoming drill program at our anchor, the Hatchet Lake Uranium Property, is designed to follow up on our new discovery from last season. The urgency to discover and define new uranium resources has never been greater. A structural supply deficit and the pressing need for procurement for utilities to secure long-term supply have created a market where sustained exploration is not just an opportunity but is viewed as imperative for energy security. This directly aligns with our exploration strategy, which focuses on high-impact discoveries in the world’s premier uranium district, the Athabasca Basin. By actively exploring in this proven jurisdiction, we are executing our plans to fulfill this critical need. We believe this presents a compelling opportunity as we advance our prospective uranium portfolio, rooted in meaningful catalysts to build long-term shareholder value.” 1 https://tradingeconomics.com/commodity/lithium Table 1 – Lithium Assay Results 1 Uses cut-off grade of 0.4% Li2O and maximum internal dilution of 1.0m 2 JL25-005B was drilled with an azimuth of 212° a dip of -70 ° located at 452829 E, 6076336N (NAD83 Zone 14) The Company has now completed its historic core re-sampling program (assays pending), the results of which will strengthen its geological model for both lithium and gold at Jean Lake. This follows the December 8, 2025, announcement that confirmed completion of the 2025 drill program and the start of the re-sampling initiative. Gold assay results from the initial four drill holes have defined a near-surface mineralized footprint that extends beyond the original discovery area. Notable results included hole JL25-001: 12.7 g/t Au over 2.1 metres (including 40.0 g/t Au over 0.6 metres) and hole JL25-002: 10.7 g/t Au over 5.6 metres (including 82.0 g/t Au over 0.7 metres) (see news release November 10, 2025). Assay results for the remaining 11 holes are still pending from the completed drill program. Figure 1. Jean Lake 2025 Drillholes and 2023 Resampled Drillhole Locations Looking ahead, Foremost plans to integrate the 2025 drill results and the historic re-sampling data into an updated geological and structural model to guide future exploration at Jean Lake. A total of six high-priority 2023 drillholes along the Valkyrie Trend were selected for re-sampling in 2025 (Figure 1). These include hole FM23-08, which previously returned 102 g/t Au over 0.5 m, within 7.50 g/t Au over 7.66 m (see news release June 06, 2023). In addition, one drillhole from the Midas Trend, FM23-25, is being re-sampled (Figure 1). Historical highlights from FM23-25 include 6.86 g/t Au over 0.54 m, within 2.07 g/t Au over 3.49 m (see news release June 06, 2023). Sampling, Analytical Methods and QA/QC Drill core samples were collected from pegmatite dykes intersected during the drilling program. All samples consisted of NQ-sized diamond drill core. Sampling intervals were selected based on geological logging, with continuous sampling through pegmatite intervals and adjacent wall rock. Sample lengths typically ranged from 0.5 m to 1.0 m, depending on lithological boundaries and internal zoning within the pegmatite. All drill core was cut longitudinally using a diamond saw, with one half retained on site for reference and future verification and the remaining half submitted for geochemical analysis. Samples were securely packaged, labelled, and shipped under chain of custody to SGS Canada Inc.’s geochemistry laboratory in Burnaby, British Columbia, for sample preparation and primary analysis. At SGS, samples were dried at 105°C, crushed to 75% passing 2 mm, and a 250 g split was pulverized to 85% passing 75 microns using standard industry procedures (method PRP89). Lithium analyses were performed using sodium peroxide fusion followed by ICP-AES determination (method GC_ICP92A50), which is suitable for lithium-bearing silicate matrices such as LCT-type pegmatites and provides a reporting limit of 0.001% Li. This method is designed to ensure complete dissolution of refractory lithium minerals and accurate quantification across a wide concentration range. All analytical work was carried out at SGS laboratories operating under ISO/IEC 17025-accredited quality management systems. SGS laboratories employ method-specific internal quality control protocols that include the routine insertion of preparation blanks, certified reference materials, duplicates, and pulp replicates. These controls are monitored through SGS’s Laboratory Information Management System, which automatically flags results that fall outside predefined accuracy or precision thresholds and initiates reanalysis when required. In addition to laboratory QA/QC procedures, Foremost Clean Energy implemented an independent quality assurance program that included the regular insertion of certified lithium reference materials, blank samples, and field duplicates into the sample stream. These control samples were used to independently assess analytical accuracy, precision, and potential contamination during sample preparation and analysis. Results from QA/QC samples were reviewed upon receipt of analytical data and were found to be within acceptable limits for lithium exploration purposes. All reported sample intervals represent downhole lengths. True widths of mineralized intervals have not yet been determined.

Drilling Confirms and Expands High-Grade Gold Mineralization VANCOUVER, British Columbia, Nov. 10, 2025 (GLOBE NEWSWIRE) -- Foremost Clean Energy Ltd. (NASDAQ: FMST) (CSE: FAT) ("Foremost" or the "Company"), is pleased to announce that it has the receipt of assay results for the first two drillholes, JL25-001 and JL25-002 from its 2025 drill program currently underway at its 100%-owned Jean Lake Gold–Lithium Property (“Jean Lake”) located near the historic mining centre of Snow Lake in Manitoba. Both holes, JL25-001 and JL25-002, successfully intersected multiple gold-bearing zones along the Valkyrie Trend (see figure 1). These results have confirmed a larger mineralized system than previously defined, notably extending the known boundaries of the gold-bearing structure. Highlights include: JL25-002: 10.7 g/t Au over 5.6 m from 100.5 m, including 82 g/t Au over 0.7 m JL25-001: 12.7 g/t Au over 2.07 m from 118.18 m, including 40 g/t Au over 0.6 m JL25-002: 5.0 g/t/Au over 2.2 m from 113 m including 21 g/t Au over .5m The assay results from the initial two drillholes, JL25-001 and JL25-002, have successfully defined a mineralized footprint that extends beyond the area of the previous discovered initial drill hole JL23-008 (7.50 g/t Au over 7.66m, including 102.0 g/t Au over 0.48 metres, as previously reported (See News Release June 6, 2023)). Jason Barnard, Foremost’s President and CEO, commented: “We are extremely encouraged that the first two holes of our 2025 program have exceeded our expectations and further demonstrate the exceptional potential of our Jean Lake Project. The presence of multiple high-grade intercepts, highlighted by an exceptional 82 grams per tonne result, strongly validates the high-grade nature of the mineralizing system. With the gold prices recently testing historic highs over US $4,000 per ounce, the timing of this high-grade discovery is optimal for Foremost. At a time of record gold prices, we are advancing a high-grade gold discovery at Jean Lake. Amid a bullish gold market, Foremost's high-grade discovery at Jean Lake represents a potential powerful growth catalyst and a truly exciting time for our company. Our drill program is ongoing, and we are eagerly anticipating the remaining results from this season's campaign, which includes further drilling on these gold targets as well as our first systematic testing of the property's significant lithium potential. We look forward to building upon this positive geological framework for both commodities and further assay results.” Figure 1. Jean Lake 2025 DDH Compilation Map 2025 Drill Program Objectives The ongoing 2025 drill program is designed to build on the high-grade gold and lithium discoveries from previous campaigns. The primary objectives are to test the extent of the gold-bearing Valkyrie Trend along strike and at depth, and to delineate the near-surface, spodumene-bearing B1 Pegmatite. Assay results for JL25-001 and JL25-002 are found in Table 1. Table 1 – Summary of Significant Gold Intercepts ________________________ 1 JL25-001 was drilled with an azimuth of 245° a dip of -45 ° located at 452872 E, 6076541N (NAD83 Zone 14) 2 JL25-002 was drilled with an azimuth of 245° a dip of -60 ° located at 452877 E, 6076539N (NAD83 Zone 14) Picture 1. Drill core from the high-grade intercept in hole JL25-001 Next Steps The results from the first two holes strongly validate Foremost’s exploration model. As the Company advances its 2025 program, drilling continues with step-out holes along the Valkyrie Trend and initial testing of additional lithium-bearing pegmatite targets. Assay results for these subsequent holes are pending. 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.

Highlights Include: Elevated linear radon trends including a one-kilometer-long anomaly trending northeast Second anomaly detected in the northeast portion of the grid, both of which remain open along strike Survey results reinforce the property’s exploration potential VANCOUVER, British Columbia, Aug. 27, 2025 (GLOBE NEWSWIRE) -- Foremost Clean Energy Ltd. (NASDAQ: FMST) (CSE: FAT) (“Foremost” or the “Company”) is pleased to announce the results of its recently completed radon survey, at the Wolverine Uranium Property (“Wolverine”), located in the world-renowned Athabasca Basin region of northern Saskatchewan, approximately 15 kilometers southeast of the Cigar Lake Mine site (see Figure 1). The radon survey, previously announced on June 25, 2025, was conducted by RadonEx Ltd. consisting of both radon flux monitoring over land and a small radon-in-water component to test adjacent wetlands. A total of 893 data points were collected over the survey grid. The survey grid was designed to cover two potential faults which may explain the notable unconformity offset1 observed on the property (see Figure 2). Jason Barnard, President and CEO states "These survey results provide strong evidence that the interpreted structures at Wolverine are associated with elevated radon anomalies which may suggest the presence of subsurface uranium. This strengthens our confidence that the property has the right geological setting to host high-grade unconformity-style uranium mineralization. With these results in hand, our technical team will now integrate the radon data with historical geophysical and drill information to refine high-priority drill targets for future testing. We look forward to advancing Wolverine, which looks like another highly promising project to the ten-project portfolio we have optioned from Denison Mines. We are eager to advance our understanding of this site and systematically unlock any significant mineral potential.” Radon Survey Results and Structural Interpretation Radon surveying is geochemical approach which leverages the relationship between radon gas emissions and the presence of subsurface uranium. As uranium decays, it produces radon gas as one of its daughter products. Because radon is a gas, it can migrate toward the surface, particularly along faults and fractures, where it can be detected and measured. Results from the radon flux monitoring identified elevated radon trends within the property, including a one-kilometer-long anomaly trending northeast and a second anomaly in the northeast portion of the grid, both of which remain open along strike (see Figure 3). To better visualize survey results, Foremost has ranked all radon flux values relative to the highest value collected during the program. The maximum value is ranked “10”, with all other results scaled accordingly. This ranked dataset highlights a pronounced NNE-trending radon anomaly that closely coincides with an interpreted structural feature on the property (see Figure 3). While the radon trend closely parallels the structure, it is slightly offset, which is expected given that the structure is interpreted from magnetics reflecting basement rocks, whereas radon values are measured at surface. This correlation suggests that the structure may be fertile and represents a compelling target for future drill programs. About the Wolverine Property Wolverine is part of Foremost’s unique collaboration with Denison Mines Corp. (TSX: DML, NYSE American: DNN) and consists of three mineral claims totaling 12,444 acres (5,036 hectares). Historic work has been conducted on Wolverine by various companies including geophysical surveys and drilling programs. Previous exploration identified uranium mineralization, including drill hole WL10-01 that intersected 2,087 ppm U over 0.1 meters2. Numerous airborne and ground-based geophysical surveys suggest a complex, structural architecture on the property. Drilling from 2011-2014 indicates up to 50m of unconformity displacement. The controlling fault is non-conductive and its precise location is uncertain. Next Steps Foremost intends to integrate the results with historical geochemical and geophysical data to refine high-priority drill targets, which could form the basis for future drill testing of the property.
