Foremost Clean Energy drilling Murphy Lake South Uranium Property, Saskatchewan
Foremost Clean Energy Ltd. [NASDAQ: FMST; CSE: FAT] reported that crews have mobilized to commence an anticipated eight-hole, 2,500-metre diamond drill at its Murphy Lake South Uranium Property located in the Athabasca Basin region of northern Saskatchewan.
The Phase 1 fully funded diamond drill program follows the successful completion of the company’s ambient noise tomography (ANT) survey, announced July 21, 2025 which generated a 3D velocity model to optimize drill hole placement to test high-priority target areas at Murphy. A Phase 2 follow-up program can be expected for the 2025/2026 winter drill season program to expand upon any initial exploration results.
“The Murphy Lake South drill program will test high-priority targets in a world-class uranium district. This strategic exploration is particularly timely, as recent production cuts from major producers like Cameco are forecast to further tighten uranium supply, highlighting the critical need for new discoveries,” commented Jason Barnard, President and CEO of Foremost.
“We are excited to build on the results of our ANT survey, which provides a much sharper picture of the subsurface architecture to refine our targeting in the hopes of turning historic anomalies into a uranium discovery. Testing the up-dip potential of the mineralized graphitic structure at drill hole MP17-19 is a compelling opportunity, as it represents a classic setting for unconformity-hosted uranium deposits. By combining modern geophysics with these proven geological controls, we are methodically and systematically evaluating the highest-priority targets and are positioning Foremost for potential meaningful discovery.”
Murphy is situated in the eastern Athabasca Basin within the Mudjatik Domain, a region with strong uranium potential. Recent exploration successes along the LaRocque corridor have underscored the potential of this area often overshadowed by the eastern Athabasca’s Wollaston Domain. The first hole of the program will test the up-dip projection of drill hole MP17-19, which previously intersected 7.5 metres of 234 ppm uranium within a graphitic structure in the basement rocks. This significant interval has remained a priority follow-up target representing an ideal setting for unconformity-style uranium mineralization. Drillhole depths are expected to be between 300 and 450 metres.
Results of the ANT survey were processed to generate a 3D velocity model of the subsurface to enhance targeting confidence by imaging structural offsets, fault zones, and alteration halos in both the sandstone and basement rocks. Similar surveys in the Athabasca Basin have demonstrated the ability to identify velocity anomalies that correlate with known uranium deposits, such as IsoEnergy’s Hurricane Deposit. Murphy Lake 3D velocity model results assisted with drill hole placement and to optimize the testing of high-priority conductive corridors.
The 17,676 acre/7,153-hectare Murphy Lake South Project is situated approximately 30km northwest of the McClean Lake mill and lies adjacent to the LaRocque Lake Conductive Corridor, host to IsoEnergy’s Hurricane Deposit, one of the world’s highest-grade published indicated uranium resources of 48.6Mlbs U3O8 at 34.5% U3O8 and inferred resource of 2.7Mlbs at 2.2% U3O82. Historical drilling on the property by Denison intersected anomalous uranium mineralization and key alteration signatures, such as 0.25% UΓéâOΓéê over 6 metres (drill hole MP-15-03); 0.13% UΓéâOΓéê over 12.5 metres just above the unconformity (drill hole MP-16-11) and 0.03% UΓéâOΓéê over 22.5 meters from 255 to 277.5 meters (MP-16-17).
The company believes that these results, together with confirmed structural complexity make Murphy a compelling Property for a uranium discovery.
Foremost Clean Energy holds an option from Denison Mines Corp. to earn up to a 70% interest in 10 prospective uranium properties (with the exception of the Hatchet Lake, where Foremost is able to earn up to 51%), spanning over 330,000 acres in the prolific, uranium-rich Athabasca Basin region of northern Saskatchewan.
Foremost’s uranium projects are at different stages of exploration, from grassroots to those with significant historical exploration and drill-ready targets.
Foremost also has a portfolio of lithium projects at varying stages of development, which are located across 55,000+ acres in Manitoba and Quebec.
