News releases from Standard Uranium often cover details of mapping, prospecting, and sampling programs, including scintillometer readings and uranium assay results from outcrop and boulder grab samples. The company also reports on geophysical surveys such as ground gravity, airborne and ground electromagnetic surveys, and magnetic surveys, which are used to refine targets along conductive and structural trends. These updates provide insight into how the company identifies gravity-low anomalies, graphitic shear zones, and other features that it interprets as prospective for uranium mineralization.
Investors following STTDF news can expect coverage of planned and ongoing diamond drill programs across multiple projects, summaries of completed drill campaigns, and interpretations of alteration zones, structures, and anomalous uranium intersections. Standard Uranium also issues news about option agreements and earn-in arrangements on projects like Corvo and Rocas, outlining partner-funded exploration plans, operator roles, and joint venture structures.
This news feed is a resource for tracking how Standard Uranium advances its Athabasca Basin exploration portfolio over time, from early-stage surface work and geophysical surveys through to drill targeting on basement-hosted and unconformity-related uranium prospects.
Standard Uranium (OTCQB: STTDF) is mobilizing a fully funded 2026 drill program at its flagship Davidson River project in the southwest Athabasca Basin. Permits are secured, the Clearwater River Dene Nation exploration agreement is signed, and two drill rigs will mobilize May 31, 2026 to test Multiphysics-refined targets across Warrior, Bronco, and Thunderbird corridors.
ExoSphere Multiphysics integration produced cover-corrected 3D models and density-low anomalies coincident with EM conductors; Saint corridor deferred for follow-up surveys.
Standard Uranium (OTCQB: STTDF) completed a 962-metre inaugural drill program at the Rocas uranium project on May 6, 2026, testing Upper Prawn Lake, Southside and Crab Lake targets. Three of four holes returned anomalous radioactivity (>300 cps) totalling 1.5 metres and combined graphitic intersections of 114 m.
All holes intersected reactivated graphitic structures, hydrothermal alteration, and sulphides; geochemical assays for U3O8 and REE are pending and a phase-two drill program is being planned.
Standard Uranium (OTCQB: STTDF) completed an inaugural winter drill program at the Corvo uranium project near Wollaston Lake, Saskatchewan.
The program completed 2,457 metres in 10 holes, with 23 metres of anomalous radioactivity (>300 cps) across seven holes; assays for U3O8 and REE are pending. Aventis may earn 75% by funding CAD$6M.
Standard Uranium (OTCQB: STTDF) signed an Exploration Agreement with Kineepik Métis Local Inc. (KML) on March 19, 2026. The agreement formalizes cooperation around exploration on KML territory in the southeastern Athabasca Basin, including the Rocas project within KML land and occupancy areas.
The partnership emphasizes information-sharing, environmental monitoring, employment, training, and support for local businesses, aiming for long-term, mutually beneficial collaboration and respectful mineral exploration in the Pinehouse, Saskatchewan region.
Standard Uranium (OTCQB: STTDF) has begun drilling at the Rocas Uranium Project on March 16, 2026, launching a ~5-week Phase I program targeting shallow, basement-hosted uranium and REE mineralization.
The program plans ~1,200–1,500 metres across 6–8 holes, targets less than 200 m depth, and is funded under a three-year option with Collective, which can earn 75% by funding CAD$4.5M.
Standard Uranium (OTCQB: STTDF) reported final assays from its 2025 prospecting on the Rocas Project, confirming anomalous uranium (up to 0.409% U3O8) and high-grade rare earth element mineralization (up to 9.83% TREO*) in outcrop and boulder grab samples. The company plans a maiden diamond drill program in March 2026 targeting a 7.5 km conductive/magnetic corridor with coincident gravity lows.
Sixteen radioactive samples were analyzed by SRC labs under QA/QC protocols; historical data remain unverified pending future work.
Standard Uranium (OTCQB: STTDF) finalised plans for the Rocas Project's inaugural drill program, with Collective Metals able to earn a 75% interest by funding CAD$4.5M in exploration.
Phase I will target shallow basement-hosted uranium with 1,200–1,500 m across 6–8 holes; surface radioactivity reached 33,000 cps with ten readings over 10,000 cps. Collective will fund 100% of year-one drilling and Standard Uranium will operate the 2026 program.
Standard Uranium (OTCQB: STTDF) has started a winter diamond drill program at its 12,364-hectare Corvo uranium project near Wollaston Lake, Saskatchewan. Drilling began February 9, 2026, with ~2,500–3,000 metres planned across 8–10 holes over five to six weeks, initially targeting the Manhattan showing.
Aventis Energy will fund the year-one program under an option to earn a 75% interest by funding CAD$6M in exploration over three years. Surface prospecting returned grab samples up to 8.10% U3O8; samples were analyzed by SRC Geoanalytical Laboratories under QA/QC protocols.
Standard Uranium (OTCQB: STTDF) has begun mobilization for a maiden diamond drilling campaign at the Corvo uranium project in the eastern Athabasca Basin, targeting the high-grade Manhattan Showing which returned a surface grab sample up to 8.10% U3O8.
The winter 2026 program plans approximately 3,000 metres of skid-supported drilling in 8–10 holes. Corvo is under a three-year earn-in option with Aventis Energy, where Aventis may fund CAD$6 million to earn a 75% interest. Drilling targets integrate 2025 high-resolution geophysics, EM conductors and gravity lows.
Standard Uranium (OTCQB: STTDF) finalized mobilization and drilling plans for a maiden winter program on the Corvo uranium project, with drilling to start in February 2026 under a three-year earn-in with Aventis Energy. The inaugural program targets approximately 2,500–3,000 metres across 8–10 holes, targeting shallow basement-hosted uranium less than 200–300 m depth.
