Welcome to our dedicated page for Standard Uranium news (Ticker: STTDF), a resource for investors and traders seeking the latest updates and insights on Standard Uranium stock.
Standard Uranium Ltd. reports developments tied to uranium exploration and project generation in Saskatchewan's Athabasca Basin. Company news centers on drill planning, reconnaissance drilling, radioactivity and assay results, geophysical targeting, and exploration work across projects including Davidson River, Rocas, and Corvo.
Updates also cover partner-funded earn-in option arrangements, exploration agreements with local rights-holder organizations, permitting, contractor mobilization, and technical programs aimed at identifying basement-hosted uranium targets in established uranium districts.
Standard Uranium (TSXV: STND, OTCQB: STTDF) reported detailed geochemical assays from its winter 2026 inaugural drill program at the Corvo Uranium Project near Wollaston Lake, Saskatchewan. Aventis Energy funded 2,457 m of reconnaissance drilling in nine completed holes across the Manhattan, Brooklyn and Tribeca target areas under a three-year earn-in option.
According to Standard Uranium, anomalous uranium was confirmed in all nine drill holes, with multiple intervals of 100–350 ppm U in six holes and U:Th ratios >2:1 indicating hydrothermal uranium input. Basement-hosted mineralization occurs in deformed and altered paragneiss, pegmatite and granitoid orthogneiss, with key fault zones and alteration suggesting a uranium-fertile system open along strike and at depth.
Elevated pathfinder elements, including boron up to 13,600 ppm in CRV-26-002, and locally enriched rare earth elements were also intersected. Hole CRV-26-009 at Tribeca returned several intervals with TREO* plus Y >0.1 wt.%, up to 0.333 wt.%. The company is integrating assays with geophysical and geological data to define follow-up surface work and a second drill phase along more than 25 km of structural strike.
Separately, Standard Uranium received a TSX Venture Exchange extension to August 11, 2026 for final acceptance and closing of its previously announced non-brokered private placement of units, with all original terms of the offering remaining unchanged and completion still subject to regulatory approvals.
Standard Uranium (OTCQB: STTDF) reported an update on its 2026 drill program at the flagship Davidson River project in the southwest Athabasca Basin.
Since June 1, 2026, about 900 metres have been drilled. First hole DR-26-040 intersected three metres of anomalous radioactivity (>300 cps) with peaks up to 1,650 cps from 464.0–466.0 metres. Two rigs are operating 24/7, with drilling planned through August 2026. Targets along the Warrior, Bronco, and Thunderbird corridors are prioritized using integrated ExoSphere multiphysics, gravity, EM, and machine-learning datasets.
Standard Uranium (OTCQB: STTDF, TSXV: STND) has started its 2026 drill program at the flagship Davidson River uranium project in Saskatchewan’s southwest Athabasca Basin.
The helicopter-supported campaign is planned to exceed 8,000 metres over about 12 weeks, testing high-priority targets along the Bronco, Thunderbird, and Warrior corridors using integrated Multiphysics and geophysical datasets.
Standard Uranium (OTCQB: STTDF) closed its previously announced LIFE offering, issuing 9,000,000 units at $0.10 per unit. Each unit includes one common share and half a warrant.
Each whole warrant allows purchase of a share at $0.15 from day 61 after closing until 36 months, with an accelerated expiry feature if shares trade at or above $0.30 for 10 straight days. Net proceeds will fund exploration of the Davidson River project and working capital. The company also paid a $54,000 finder’s fee and issued 540,000 finder warrants on the same terms, subject to a hold period until September 20, 2026.
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.
