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 (STTDF) has begun an Aventis Energy-funded surface exploration program at its Corvo uranium project in Saskatchewan. Crews mobilized on October 1, 2026, for mapping, prospecting and sampling under the project's three-year earn-in option agreement, with Standard Uranium operating the program.
The work follows winter 2026 drilling that confirmed uranium enrichment in all nine holes. Results included 55 metres above 10 ppm uranium, including 23 metres above 50 ppm and 13 metres above 100 ppm, using partial analysis. Surface work will investigate known showings, including Manhattan, where modern samples returned up to 8.10% U3O8, a uranium oxide measure. Standard Uranium plans to integrate surface, drilling and geophysical data to refine targets for follow-up drilling in 2027. Priority targets remain along more than 25 km of structural strike length, the extent along geological structures.
Standard Uranium (STTDF) completed 6,734 metres of summer drilling at its Davidson River uranium project in Saskatchewan’s southwest Athabasca Basin. The program covered twelve diamond drill holes across the Warrior, Bronco and Thunderbird corridors. Three holes intersected anomalous radioactivity across 5.0 metres of combined intervals, with a maximum handheld reading of 1,650 counts per second in hole DR-26-040.
Drilling more than doubled the known widths of the Thunderbird and Bronco structural corridors to greater than 300 metres across strike. It also encountered graphitic faults, shear zones and hydrothermal alteration; initial clay analysis confirmed dravitic-clay alteration in DR-26-040. Geochemical assays remain pending, and radioactivity readings do not directly establish uranium grades. One hole required restarting because of difficult ground conditions. The company plans follow-up exploration, with more than 60 km of untested strike length remaining.
Standard Uranium (STTDF) reported approval of all annual meeting items and granted equity awards to directors, officers and consultants.
At the September 24, 2026 meeting, shareholders set the board at five and re-elected Jon Bey, Blair Jordan, Kenneth Judge, Mike Young and Douglas Engdahl. They approved Davidson & Company as auditor for the ensuing year, its remuneration, and re-approved the omnibus incentive plan.
The company granted 2,300,000 options and 4,050,000 restricted share units under that plan. The options are exercisable at $0.08 until September 25, 2031. They vest in five equal parts: 20% on the grant date and another 20% every three months over 12 months. The restricted units vest and settle in common shares on September 25, 2027, provided holders remain eligible on that date.
Standard Uranium (STTDF) has received TSX Venture Exchange approval to extend the closing deadline for its previously announced private placement Offering. The date by which final closing materials must be filed has moved from September 21, 2026 to October 18, 2026, with all other terms and conditions of the Offering remaining unchanged.
The company plans to issue a further news release once the Offering has been completed. The rest of the announcement provides background on Standard Uranium’s Athabasca Basin exploration portfolio and recent joint venture partnerships.
Standard Uranium (OTCQB: STTDF) reported detailed geological and geochemical results from its winter 2026 inaugural drill program at the Corvo Uranium Project near Wollaston Lake, Saskatchewan. The Aventis-funded campaign totaled 2,457 metres in ten reconnaissance holes across the Manhattan, Brooklyn, and Tribeca target areas, with one hole abandoned due to ground conditions.
All nine completed holes intersected anomalous uranium, totaling 55 metres >10 ppm U, including 23 metres >50 ppm and 13 metres >100 ppm (partial digestion). Pathfinder elements (V, Co, Cu, Ni) are elevated alongside uranium. Calculated U:Th ratios average 1.5–5, locally up to 21, and 206Pb/204Pb ratios from 405 samples average 147, with 27 samples >400 and a maximum of 5,100, consistent with uranium-enriched systems. Drilling also defined stacked graphitic faults, high-strain zones, and hydrothermal alteration along multi‑kilometre structural trends. Standard Uranium plans further surface work and a second drill phase in 2027.
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.
