On June 25, 2026, Cosa Resources Corp. (“Cosa”) announced the commencement of a property-wide airborne radiometric survey at the Aurora project located in the southeastern Athabasca Basin approximately 16 km east of Cameco’s Key Lake Mill and past-producing uranium mine (Figure 1).

Athabasca sandstone cover is expected to be less than 100 metres thick in the northern third of Aurora and absent in the remainder. Though no diamond drilling has been completed on the Project since 1979, review of historical drill hole logs by Cosa has identified several zones of hydrothermal alteration. Airborne gravity gradient and Versatile Transient Electromagnetic (VTEM) surveying completed by Cosa in 2024 identified initial target areas at Aurora (Figure 2).

The survey and supporting work are fully funded by Traction Uranium Corp. under the option agreement between Cosa and Traction dated February 10, 2026. Traction has the right to earn up to an 80% interest in the Aurora project by sole-funding $9.15 million in exploration expenditures and completing specified cash and share payments.  The radiometric survey and supporting work are 100% funded by Traction.

Project-wide radiometric surveying will be flown by Calgary-based Special Projects Inc. using their custom 16-detector focused gamma-ray spectrometer at 50-metre line spacing with the objective of identifying radiometric anomalies potentially indicative of near-surface uranium mineralization. Results to be used to guide a proposed 100% partner-funded fall drilling program at Aurora.
