Cosa Resources and Denison Mines Report Radioactivity Discovery at Murphy Lake North

Key Facts

1Cosa Resources reported intersecting 5.0 metres of anomalous radioactivity at the Murphy Lake North Project.
2Radioactivity levels reached a peak of 13,900 counts per second (CPS).
3The project is a joint venture between Cosa Resources and Denison Mines, located near IsoEnergy's Hurricane Deposit.

Cosa Resources and Denison Mines have announced a significant discovery of anomalous radioactivity at their Murphy Lake North Project in the Athabasca Basin. During the winter 2026 drilling program, the exploration team intersected a 5.0-metre zone of radioactivity with peak levels reaching 13,900 counts per second (CPS). The project is a joint venture located strategically near IsoEnergy's Hurricane Deposit, a region renowned for high-grade uranium discoveries. This discovery marks a positive step in the ongoing exploration efforts to identify new uranium resources in the area. Investors are closely monitoring these early-stage results as they could impact the valuations of both companies. The discovery is expected to drive further interest in junior and mid-tier uranium miners operating in the Canadian basin.
