Mineral resource
Cosa Resources’ 100% owned uranium land package comprises over 220,000 ha across multiple projects in the Athabasca Basin region, the world’s most prolific district for high-grade uranium discoveries. Many of Cosa’s projects are underexplored or virtually untouched by modern exploration and offer significant upside potential through discovery of the next tier-1 uranium deposit.

Drilling during Cosa’s recent summer campaign successfully identified a new zone of basement-hosted radioactivity within a broader interval of hydrothermal alteration in the basement and lower sandstone. The Company believes that the work completed to date, including deployment of Ambient Noise Tomography (ANT) over much of the Kodiak trend, has significantly upgraded the project by identifying several anomalies that are similar to what was targeted where the company intersected radioactivity. With no drilling within roughly two kilometres of the radioactive intercept, Cosa’s technical team is eager to return to Ursa for follow up work.

The Project covers approximately 25 kilometres of strike length of the interpreted extension of the Larocque Lake Trend. Cosa has repeatedly expanded its 100%-owned, 20,255-hectare Orion Project since initial acquisition in 2022 as the fertile Larocque Lake Trend hosts numerous occurrences of high-grade mineralization to the northeast while the portion covered by Orion is highly underexplored. Orion is on the interpreted western extension of the Cigar Lake – Tucker Lake trend where it intersects the Larocque Lake trend. Drilling on trend at Parker Lake has intersected broad zones of structural disruption in the sandstone with illitic hydrothermal alteration and anomalous uranium geochemistry, including 0.05% U3O8 over 1.0 metres (932.4-933.4 metres) immediately above the unconformity in drill hole PAR-03. Basement intersections included graphitic lithologies and structures, indicating basement geology and sandstone alteration along trend is consistent with deposits in the region. In 2023, MobileMT™ surveying completed by Cosa over the western portion of Orion identified basement hosted conductive zones overlain by conductivity anomalies in the sandstone. Follow up ANT surveying in 2024 identified several kilometre-scale and vertically extensive low velocity anomalies which are interpreted to reflect prospective structures and/or alteration above conductive basement zones and are considered high priority targets for additional follow up.

The Key Lake Mine produced 209.8 million pounds of U3O8 at an average grade of 2.3% U3O8 from deposits situated along a 065-degree trending conductive corridor with associated 045-degree trends. The Key Lake Mill processes ore from the McArthur River Mine. Provincial Highway 914 passes within 17 kilometres of Orbit. Three initial target areas were identified at Orbit from the airborne VTEM and gravity survey results. Target area O1 is considered the highest priority and features a 1.6-kilometre-long EM conductor with coincident gravity lows located on the northern flank of a magnetic high. Similar to Key Lake geology, the O1 conductor is oriented at 065 degrees. An interpreted north-south oriented magnetic lineament crosscuts the center of the O1 conductor and is coincident with a gravity low, similar to the GMZ discovered in 2021. A second gravity low anomaly is present on the western end of the O1 conductor coincident with a flexure to the south and is crosscut by an 065-degree trending magnetic break. The O2 target area is a bedrock conductivity anomaly with an enveloping gravity low. The O3 target area is at the intersection of interpreted 045- and 065-degree trending magnetic lineaments and contains the strongest gravity low zone identified at Orbit.

Provincial Highway 905 passes within seven kilometres of the Property and a network of trails and a provincial powerline pass through the Property. Cosmo covers 18 kilometres of curvilinear magnetic low strike length interpreted to represent favourable metasediments. Historical exploration was limited to a 1979 lake sediment sampling program and a 2007 airborne geophysical survey. While no drilling is known within the Property, historical drilling located 13 to 25 kilometres along strike to the east intersected several intervals of weak uranium mineralization, including 0.20% U3O8 over 1.2 metres in drill hole BL-14-20 (549.9 – 551.1 m).

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. 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.","Aurora: The Aurora Project covers a 17-kilometre section of the southeastern rim of the Athabasca Basin located 16 kilometres east of Key Lake and 40 kilometres south of the GMZ. Sandstone cover is expected to be less than 100 metres thick in the northern third of Aurora and absent in the remainder. Aurora was last drilled in 1979 and ground work since 1989 is limited to surficial sampling and prospecting. Historical drill logs suggest the presence of favourable structure and alteration. Three initial follow-up target areas were identified by VTEM and gravity surveying at Aurora. The A1 target area is the highest priority and characterized as a bedrock-hosted conductive feature trending 045 degrees proximal to interpreted magnetic lineaments at orientations similar to Key Lake (045 and 065 degrees) and the GMZ (north-south). The A2 target area is a single-line conductive response interpreted to be basement-hosted. The A3 target area is a trend of gravity low zones along a prominent, 065-degree trending magnetic lineament. Similar to Key Lake, the A3 area is bracketed by 045-degree trending magnetic lineaments."]
