Cosa Commences Partner Funded Airborne Radiometric Survey at the Aurora Uranium Project, Athabasca Basin, Saskatchewan
Cosa advances its Athabasca Basin uranium portfolio through partner-funded exploration and strategic joint ventures.
Cosa Resources Corp. has commenced a 100% partner-funded airborne radiometric survey at its Aurora uranium project in the Athabasca Basin. The survey is fully financed by Traction Uranium Corp., which holds an option to earn up to an 80% interest in the project by spending $9.15 million and completing cash and share payments.
The airborne survey, flown at 50-metre line spacing, will integrate with historical and 2024 geophysical data to guide a proposed inaugural drilling program tentatively scheduled for early September 2026. This announcement follows the February 11, 2026 option agreement and represents the execution of Phase 1 exploration milestones. No capital is being raised for Cosa; the partner bears 100% of the survey costs.
Cosa Resources Corp. (COSA) has executed a radiometric survey at its Aurora project, a direct follow-up to the February 2026 option agreement with Traction Uranium. The survey represents a known and expected step within the earn-in structure and is fully partner-funded, resulting in zero dilution or cash outflow for Cosa. This operational milestone advances the Aurora project toward its 2027 drilling target without impacting the company's balance sheet.
The Aurora project remains a lower-priority asset compared to the Murphy Lake North (MLN) and Darby joint ventures with Denison Mines, which are currently consuming the majority of management's attention and capital. The market likely anticipated this survey given the February announcement. The news provides incremental validation of the option agreement but does not introduce new financial or operational catalysts that would materially shift the company's valuation or near-term trajectory.
Cosa Resources Corp. (COSA) is an exploration-stage uranium company focused on the Athabasca Basin in Saskatchewan, Canada. Its flagship projects, Murphy Lake North (MLN) and Darby, are operated as 70/30 joint ventures with Denison Mines.
MLN is located 3 km east of IsoEnergy's world-class Hurricane deposit. Winter 2026 drilling intersected 5.0 metres averaging 0.55% U3O8, including a high-grade 0.5 metre interval at 1.70% U3O8. The zone remains open along strike for 600 metres in both directions.
Darby is situated 10 km west of Cameco's Cigar Lake Mine. Winter 2026 drilling identified strongly anomalous uranium in sandstone at the Charlie trend and significant structural alteration at the Gamma trend.
The company also holds 100% owned projects including Ursa, Orion, Orbit, and Aurora. Option agreements exist with Traction Uranium (Aurora) and Global Uranium (Astro). Cosa Resources is in the exploration stage, and no mineral resources or reserves have been defined.
