- ANT surveys at Cosa Resources' Ursa and Orion projects identified key uranium targets.
- Initial drilling at Ursa's U1 target revealed over 100 meters of sandstone alteration and weak uranium mineralization.
- Cosa's exploration focus for summer 2025 includes expanded drilling at Murphy Lake North Joint Venture.
Cosa Resources Corp. (OTCQB: COSAF) has released encouraging results from its ambient noise tomography (ANT) surveys at the Ursa and Orion uranium projects, located in Saskatchewan's Athabasca Basin. The surveys have successfully identified several kilometer-scale ANT velocity anomalies, suggesting the presence of significant uranium-bearing hydrothermal systems.
The Ursa project revealed two high-priority targets, U1 and U2, along the 27-kilometer Kodiak trend. Initial drilling at the U1 target intersected over 100 meters of continuous sandstone alteration, which included a 65-meter zone with intervals of lost core and increased uranium content. Weak uranium mineralization was also found, validating Cosa's strategic use of ANT surveys to prioritize drilling targets.
At the Orion site, three priority targets (O1, O2, and O3) were identified, each showing promising structural characteristics and measuring approximately 1.6 to 1.8 kilometers in length. The company plans to conduct ground electromagnetic (EM) surveys at Ursa to further refine these targets before proceeding with additional drilling. Meanwhile, at Orion, historical survey data will be reinterpreted to determine if more ground EM surveys are needed.
Looking ahead, Cosa Resources is gearing up for an expanded summer drill program at the Murphy Lake North Joint Venture, aiming to build on the positive outcomes from their winter 2025 drill program. Additionally, geophysical work is set to continue at Cosmo and Orion, alongside target generation efforts at the Darby Lake Joint Venture.
