Highlights 

  • Foremost Clean Energy completes a 2,695 m, seven-hole drill program at Murphy Lake South. 
  • Drilling confirms key geological features linked to Athabasca-style uranium systems. 
  • Elevated radioactivity encountered in multiple holes signals active uranium-bearing fluids. 
  • Shallow unconformity depths of 200–350 m allow cost-effective follow-up work. 
  • Assay results from SRC are pending and expected to guide the next exploration phase. 

Foremost Clean Energy Ltd. (CSE:FAT)has successfully wrapped up a 2,695-metre diamond drill program across seven holes at its Murphy Lake South Uranium Property in Saskatchewan’s Athabasca Basin. This marks the first drilling on the property since 2017 and was designed to build on historic targets defined by Denison Mines Corp. 

Supported by a modern exploration 3D velocity model derived from ambient noise tomography, Foremost refined drill targeting along graphitic structural corridors known to act as conduits for uranium-bearing fluids. The program intersected extensive hydrothermal alteration, reactivated basement structures, and zones of elevated radioactivity—key hallmarks of unconformity-style uranium systems. 

Notably, the alteration footprint at Murphy has now been extended by approximately 600 metres, reinforcing the presence of an active mineralizing system. 

Elevated Radioactivity and Confirmation of Mineral System 

Across several holes, Foremost recorded elevated radioactivity in both graphitic basement structures and sandstone units near the Athabasca unconformity. Holes MP25-003, MP25-006, and MP25-007 all showed readings measuring 2–3 times background levels, confirming movement of uranium-bearing fluids. 

The drill program strategically followed up on previous intersections reported by Denison, which included intervals such as 0.25 percent U3O8 over 6 metres and 0.13 percent U3O8 over 12.5 metres. Current results indicate continuity of the 400-metre mineralized corridor previously identified, with alteration features such as hematite, clay, bleaching, and fracturing consistently recorded across the new holes. 

The relatively shallow unconformity depth of 200–350 metres presents an additional advantage, offering lower-cost drilling opportunities for future phases. 

Next Steps  

Core samples from all seven holes have been submitted to the Saskatchewan Research Council for multi-element analysis and U3O8 assays. Results are expected in the coming weeks and will be integrated into a comprehensive geological model to guide the next stages of exploration. 

Conclusion 

Foremost Clean Energy’s latest drill campaign at Murphy Lake South reinforces the property’s potential within one of the world’s most prolific uranium districts. By leveraging historic data, modern geophysics, and systematic exploration planning, the company has confirmed key geological features associated with uranium mineralization. Pending assay results will be critical in determining the scope and direction of the next round of drilling as Foremost continues its mission to develop high-impact discoveries in collaboration with Denison Mines.
