Cosa Resources – Results From 13 Drill Holes Along The Cyclone Trend At Murphy Lake North JV Project

The KE Report Sep 14, 2026 8:31

Summary

Cosa Resources completed a 13-hole, 6,752-metre drill program along the Cyclone Trend at Murphy Lake North, with every hole intersecting structure or alteration.

The N-fault is the most prominent basement structure intersected so far — follow-up drilling is planned next winter along with the S-fault.

An ~C$16M treasury fully funds 2027 programs at Murphy Lake North and the Darby JV, both with Denison Mines as partner.

Drilling also mobilizes soon at Darby and in Q4 2026 at the Aurora project, where Traction Uranium funds 100% of the work.

Management frames Cyclone as early-stage: the trend remains open for several hundred metres of strike with basement-hosted potential still untested.

Key points on Cosa Resources

  • The guest reports completing 13 holes (over 6,700 m) on the Cyclone trend at the Murphy Lake North JV, with elevated counts per second in multiple holes — below winter 2025 levels but still described as promising given strong alteration and structure.
  • Plans to return to the Cyclone trend next winter (2027) for follow-up drilling, citing uranium mineralization, significant open space, and a wide-long corridor defined by a north fault and a south fault that have only been scratched.
  • Treasury sits at roughly C$16 million as of the Sep 2026 interview — described as fully funded for large drill programs at Murphy Lake North in 2027 with runway extending into 2028.
  • The drill rig is moving next to the Darby target (also a Denison JV), following up elevated uranium in sandstone and strong structure from the winter program.
  • The guest points to basement-style deposit potential at Cyclone, drawing analogies to Cameco's Millennium and Rabbit Lake in addition to unconformity analogs like MacArthur River and Phoenix.

Keith Bodnarchuk's takeaways

  • Top takeaway The guest argues the evidence at the Cyclone trend warrants persistence — uranium mineralization, multiple kilometers of strong alteration, and a wide-long corridor with two major faults all support continuing to step out systematically rather than chase the original winter hit.
  • Frames uranium exploration as a 'treasure hunt' harder than gold or copper, and stresses disciplined, systematic step-outs over speculative drilling as the path to an economic discovery.
  • Argues the team has a multi-year discovery runway: a ~C$16M treasury funds large 2027 drill programs at Murphy Lake North and extends into 2028, with Darby and Aurora also advancing.
  • Maintains that basement-style targets (analogous to Cameco's Millennium and Rabbit Lake) are present at Cyclone and warrant follow-up drilling next winter.
  • Confirms the Hurricane trend — parallel to Cyclone and untouched since two programs ago — remains a target for the 2027 plan, with Denison's and Cosa's technical teams collaborating on the next set of drill targets.
