Proven district. Proven team.
Next discovery?
Saskatchewan's Athabasca Basin is home to some of the world's highest-grade uranium deposits. Cosa Resources is advancing exploration in this proven district with an experienced discovery team and growing exploration momentum.
WHY COSA STANDS OUT:
- Team involved in discovering Hurricane, Gryphon and GMZ
- Up to 1.7% U₃O₈ confirmed at Murphy Lake North
- Approximately 237,000 hectares of uranium exploration projects
- Strategic partnership with
Denison Mines
Why Canadian uranium? Why this team?
Saskatchewan's Athabasca Basin is home to the highest-grade uranium deposits on earth, backed by established infrastructure and a stable mining jurisdiction. In a district like this, the team that reads the signals early makes the difference.
The Athabasca Basin is a primary destination for uranium explorers, with grades often 10 to 100 times the global average.
Cosa holds a 70% interest in joint ventures with Denison Mines. The partnership de-risks early-stage capital and signals quality.
Assays up to 1.7% U₃O₈ over 0.5 m within 5.0 m averaging 0.55% U₃O₈ at Murphy Lake North, with the system confirmed across 650 m of strike.
Debt-free with approximately C$16 million in treasury, a 70/30 joint venture with Denison Mines, and partner-funded drilling at Aurora.

Experience that drives exploration forward.
In uranium exploration, the right geology is only part of the equation. Identifying and advancing promising targets requires experience, technical discipline and the ability to act on results.
Cosa's team brings a track record of involvement in significant Athabasca Basin discoveries. With mineralization confirmed at Murphy Lake North, ongoing work across its portfolio and support from Denison Mines, Cosa continues to advance its Canadian uranium exploration strategy.
