Cosa Commences Airborne Geophysical Surveying at the Astro Uranium Project, Athabasca Basin, Saskatchewan
Cosa Resources has initiated airborne geophysical surveying at its Astro uranium project in Saskatchewan's Athabasca Basin. The survey, conducted by Geotech using their exclusive ZTEM system, is fully funded by partner Global Uranium under an agreement that allows Global to earn up to 80% interest in the project.
The comprehensive survey will cover over 1,460 line-kilometres of the 45,000-hectare property, which is strategically located within 30km of Cameco's McArthur River uranium Mine and 10km of CanAlaska's Pike Zone discovery. The ZTEM system will map conductive trends, potential hydrothermal alteration zones, and regional structures potentially related to nearby uranium deposits.
Following the survey, Condor Consulting will perform detailed interpretation of results, guiding future exploration work including Ambient Noise Tomography and ground-based electromagnetic surveys through 2025-2026. The most promising areas identified will be prioritized for drill testing in a phased exploration program.

Survey Details
Property-wide ZTEM surveying planned to total over 1,460 line-kilometres is underway. Surveying is expected to significantly advance the understanding of the Property and identify target areas for follow up work by mapping conductive trends in the basement, potential zones of hydrothermal alteration in the sandstone, and regional structures believed to be related to the nearby Fox Lake and McArthur River uranium deposits. Historical ZTEM surveys cover less than
Exclusive to Geotech, the ZTEM system is widely used within the Athabasca Basin as it boasts a demonstrated industry leading ability to provide a wide range of frequency measurements with high accuracy and resolution at depth. Condor Consulting Inc. ("Condor"), recognized experts in the field of geophysical data processing and interpretation with extensive experience with both the ZTEM system and the Athabasca Basin, have been retained to perform a detailed interpretation of the results.
Results of the survey and data inversion will guide follow up work, which is likely to include a combination of cutting-edge Ambient Noise Tomography ("ANT") surveying and ground-based electromagnetic ("EM") surveys through the remainder of 2025 and into early 2026. The most prospective areas identified from these surveys will be prioritized for drill testing as part of a phased exploration program.
About Astro
The Astro Project is located roughly 28 kilometres west of Cameco's McArthur River Mine, the world's largest high-grade uranium mine, and approximately 10 kilometres west of CanAlaska Uranium Ltd.'s Pike Zone, which boasts world-class intersections (Figure 1). Airborne geophysics completed in 2023 at Cosa's neighboring Ursa project confirmed that untested conductive trends continue from Ursa onto the Astro Project. Additionally, over 20 kilometres of conductive strike has been identified by historical surveys at Astro, which has been tested by a single drill hole, EK-01. EK-01 failed to explain the strong conductive response it was targeting, suggesting the hole was not ideally located. However, the historical drill log notes favourable features in the sandstone including a brecciated and silicified interval in the upper portion, decametre-scale intervals of illite-dominated clay mineralogy throughout, and moderately bleached and slightly friable intervals in the lower 150 metres, features which are commonly associated with unconformity related uranium deposits of the Athabasca Basin including McArthur River, Cigar Lake, and Hurricane. Roughly 11 kilometres to the southwest of EK-01 and within 700 metres of the Astro Project, strongly anomalous uranium geochemistry and pervasive hydrothermal alteration was intersected in the lower to medial sandstone of historical drill holes CR-06 and CR-15. Drilling completed by Cosa in 2024 failed to explain the source of the geochemical anomaly however ground-based EM work completed by Cosa indicates that the targeted conductor likely trends onto the Astro Project.
Astro hosts over 40 kilometres of magnetic low strike that has been untested by drilling, the vast majority of which has not been covered by any modern EM survey. A patchwork of historical airborne and ground EM surveys covering a portion of the contained magnetic low strike length has defined that conductive trends are present within most surveyed areas. Notably, the Project is entirely unexplored for the extension of regional structures related to both the McArthur River and Fox Lake uranium deposits, located roughly 28 and 17 kilometres east of Astro, respectively. Cosa and Global Uranium will execute a work plan designed to rapidly and efficiently canvas much of the Astro Project for early identification of the most compelling and high-upside drill targets. The depth to the unconformity at Astro is estimated to be between 850 and 975 metres.

About Cosa Resources Corp.
Cosa Resources is a Canadian uranium exploration company operating in northern Saskatchewan. The portfolio comprises roughly 237,000 ha across multiple
In January of 2025, the Company entered a transformative strategic collaboration with Denison Mines that has secured Cosa access into several additional highly prospective eastern Athabasca uranium exploration projects. As Cosa's largest shareholder, Denison gains exposure to Cosa's potential for exploration success and its pipeline of uranium projects.
Cosa's award-winning management team has a long track record of success in Saskatchewan. In 2022, members of the Cosa team were awarded the AME Colin Spence Award for their previous involvement in discovering IsoEnergy's Hurricane deposit. Prior to Hurricane, Cosa personnel led teams or had integral roles in the discovery of Denison's Gryphon deposit and 92 Energy's GMZ zone and held key roles in the founding of both NexGen and IsoEnergy.
The Company's core focus throughout 2025 is drilling at the Murphy Lake North Joint Venture. Murphy Lake North is a 70/30 Joint Venture between Cosa and Denison respectively and is located at the northern end of the Larocque Lake trend. The Project is within three kilometres of and on trend with the Hurricane deposit. Initial drilling completed by Cosa during winter 2025 intersected broad zones of hydrothermal alteration of the sandstone, associated with prospective basement structures interpreted as the strike extension of those controlling the Hurricane deposit. An expanded follow up campaign is currently in planning for the summer season.
