Standard Uranium planning inaugural drill program at Rocas Uranium Project, Saskatchewan
Standard Uranium Ltd. [TSXV: STND; OTCQB: STTDF; FSE: 9SU0] has finalized plans for the first ever drill campaign on the Rocas Uranium Project, Saskatchewan. The project is currently under a three-year earn-in option agreement with Collective Metals Inc. [CSE: COMT]. Under the option agreement, Collective has been granted an option to earn a 75% interest in the project by funding CAD$4.5M in exploration expenditures and completing a series of cash and shares payments to the Company over three years.
Standard Uranium and Collective announced plans for an inaugural drill program at the Project, located south of the historical Key Lake Mine and currently active Mill facilities in the eastern Athabasca Basin. High-priority uranium target areas have been identified following the verification of anomalous uranium occurrences across the project during the company’s 2025 prospecting and mapping program. These results, combined with compelling geophysical anomalies identified in the 2024 high-resolution ground gravity survey and their integration with historical electromagnetic (EM) corridors and fault structures, have refined and strengthened the Company’s drill targeting strategy.
Highlights – Drill Plan Finalized: Phase I drilling will comprise approximately 1,200 to 1,500 metres planned across six to eight drill holes, targeting shallow, high-grade* basement-hosted uranium mineralization. This will mark the first drill program in the project’s history.
Robust Drill Targets: Diamond drilling will test target zones defined by anomalous uranium identified during the 2025 prospecting program, as well as geophysical work completed in 2024. Geophysical target zones on the Project are located approximately 100 to 200 metres below surface.
2025 Prospecting and Mapping: Preliminary results from the surface prospecting and mapping program identified anomalous radioactivity readings of up to 33,000 counts-per-second (cps), along with 10 separate occurrences exceeding 10,000 cps.
Fully Funded: Collective will fund 100% of the drill program to satisfy the year-one expenditure requirements under the Option Agreement. Standard Uranium will continue to act as operator for the 2026 exploration programs.
Key Vendors Secured: The company has engaged all key contracts for the program and diamond drilling crews will mobilize to the Rocas Project as early as mid-March to “
“The technical team and partners at Collective are thrilled to embark on what will be the first drill program in the history of the Rocas Project. We have worked to integrate the highest-confidence geoscientific data currently available to identify robust targets along an untested structural corridor that we believe is uranium-fertile,” said Sean Hillacre, President & VP Exploration. “Our exploration thesis for the project is focused on targeting shallow, structurally hosted, high-grade uranium mineralization.”
Rocas Exploration Overview: The company plans to complete the first-ever drill program on the Project in Q1 2026 to begin testing high-priority zones along the main 7.5-kilometre magnetic low/EM conductive corridor, which hosts several uranium occurrences and has remained untested by drilling to date.
In 2024, the company contracted MWH Geo-Surveys (Canada) Ltd. to carry out a high-resolution ground gravity survey over the Rocas Project. Convolutions Geoscience Corp. subsequently completed the processing, interpretation, and modelling of the gravity data. The survey outlined several gravity-low anomalies coincident with historical surface mineralization, lakebed geochemical anomalies, and cross-cutting fault zones along the known conductive exploration trends on the project.
In September of 2025, Standard Uranium completed a detailed prospecting and mapping program on the Project. Historical mineralized outcrop grab samples along approximately 900 metres of strike length, returned values ranging from 587 ppm U (SN85073) up to 0.498 wt.% U3O8 (SN23901) and have never been drill tested2. Preliminary results of the prospecting and mapping program identified anomalous radioactivity up to 33,000 cps, as well as 10 separate measurements of greater than 10,000 cps. Geochemical assay results are pending.
Paired with the results from a high-resolution ground gravity survey completed in 2024, this highlights potential alteration halos and identifies high-priority exploration targets along well-defined structural corridors.
Historical airborne EM work conducted in 2017 defined conductive trends on the Project, located west of and sub-parallel to the Key Lake Road shear zone, corresponding with favourable metasedimentary basement lithologies. Multiple parallel conductors, offsets, and termination points indicate a widening of the trend and the presence of potential cross-cutting structures. Additionally, a 2007 field sampling program identified anomalous lakebed geochemical results that rank above the 95th percentile for U, Co, V, and Zn along the conductor corridor, including elevated U/Th ratios.
The company believes the project is highly prospective for the discovery of shallow, high-grade basement-hosted uranium mineralization. Positioned proximal to the margin of the Athabasca Basin, Rocas boasts shallow drill targets within bedrock under minimal glacial till cover.
Standard Uranium is a uranium exploration company and emerging project generator poised for discovery in one of the world’s premier uranium districts. The company holds interest in over 241,652 acres (97,793 hectares) in the Athabasca Basin in Saskatchewan. Since its establishment, Standard Uranium has focused on the identification, acquisition, and exploration of Athabasca-style uranium targets with a view to discovery and future development.
Standard Uranium’s eastern Athabasca projects comprise over 53,166 hectares of prospective land holdings. The eastern basin projects are highly prospective for unconformity related and/or basement hosted uranium deposits based on historical uranium occurrences, recently identified geophysical anomalies, and location along trend from several high-grade uranium discoveries.
