Standard Uranium (OTCQB: STTDF) announced that, effective December 11, 2025, the Sun Dog Project has returned to the company as 100% unencumbered ownership following conclusion of an arm's-length option agreement with Aero Energy. The 48,443-acre project hosts the historical Gunnar mine, which produced ~18M lbs U3O8 (1953–1981), and contains recent surface assays to 17.4% U3O8 plus modern geophysics and drilling.
Standard Uranium plans to advance exploration building on 4,062 m of diamond drilling, airborne VTEM and ground gravity surveys, and multiple verified target areas.
Standard Uranium (OTCQB: STTDF) received an 18-month exploration permit for the Corvo Uranium Project and has started a ground gravity survey ahead of a planned drill program in January 2026. The company contracted MWH Geo-Surveys to complete a 50 m x 200 m gravity grid covering over 29 km of conductive strike with >5,000 gravity stations. A skid-assisted diamond drill program of approximately 3,000 metres is planned for winter 2026, targeting the never-before-drilled Manhattan Showing and other radioactive occurrences. Surface assays cited include up to 8.10% U3O8 and historical results up to 59,800 ppm. An NI 43-101 technical report has been filed and ongoing geophysical modelling will refine drill targets.
Standard Uranium (OTCQB: STTDF) outlined its 2026 exploration program and summarized 2025 results across multiple Athabasca Basin projects.
Key 2026 plans include a drill-ready Davidson River program of approximately 8,000 metres in spring 2026, a first Corvo drill program of ~3,000 metres (first drilling in >40 years) following a 2025 gravity and EM campaign, and a first-ever Rocas drill program of ~1,800 metres. 2025 work produced high-resolution ExoSphere and ground gravity targets, Sun Dog assays showing anomalous uranium in all eight 2024 holes, and Corvo surface samples up to 8.10% U3O8. The company granted 1,475,000 options and 3,350,000 RSUs.
Standard Uranium (OTCQB: STTDF; TSXV: STND) filed a NI 43-101 technical report titled "Technical Report on the Corvo Property - Northeastern Saskatchewan, Canada" with an effective date of October 24, 2025.
The report was co-prepared by Axiom Exploration Group Ltd. and co-authored by Qualified Persons Troy Marfleet, P.Geo., and Sean Hillacre, M.Sc., P.Geo. The disclosure notes the report does not contain a Mineral Resource Estimate (MRE). The Report is available on SEDAR+ and the company website.
Standard Uranium (OTCQB: STTDF) reported final assay results from its 2025 Corvo exploration program, including surface outcrop grab samples returning up to 8.10% U3O8 at the Manhattan showing and additional samples of 5.14% and 4.23% U3O8. A total of 30 outcrop and boulder samples were submitted to SRC Geoanalytical Laboratories, with 28 radioactive samples reported for uranium and TREO*.
The company identified new radioactive occurrences via scintillometer prospecting, completed a 1,380 line-km airborne TDEM/magnetic survey outlining >29 km of conductive trends, and plans a ground gravity survey in December 2025 and a diamond drill program in Q1 2026.
Standard Uranium (OTCQB: STTDF) reported preliminary results from its September 30–October 8, 2025 prospecting program at the 4,002-hectare Rocas Project, ~75 km southwest of Key Lake. Field crews recorded strong surface radioactivity including peak handheld scintillometer readings up to 33,000 cps, 73 readings >300 cps and 10 readings >10,000 cps. Geological mapping traced deformed, hydrothermally altered basement lithologies along > 7.5 km of exploration strike. A 2024 high-resolution ground gravity survey highlighted gravity lows and priority targets along conductive corridors. Historical grab samples on ~900 m of strike returned up to 0.498 wt% U3O8.
A maiden diamond drill program is planned for 2026 to test high-priority targets.
Standard Uranium (OTCQB: STTDF) has signed a definitive property option agreement with Collective Metals Inc., granting the latter an option to acquire a 75% interest in the 4,002-hectare Rocas Project in the eastern Athabasca Basin region. The project features over 7.5 km of exploration strike length along a magnetic low trend with EM conductors.
The Rocas Project showcases promising characteristics including uranium mineralization at surface with grades up to 0.5% U3O8 along 900 meters of strike length, which remains untested by drilling. The company has initiated its inaugural exploration program on September 30th, 2025, focusing on detailed mapping, prospecting, and sampling to verify historical uranium surface showings.
Standard Uranium (OTCQB: STTDF) has announced promising results from its 2025 exploration program at the Corvo Uranium Project. The company confirmed off-scale radioactivity exceeding 65,535 counts per second (cps) at the historical Manhattan showing, along with 112 additional occurrences of highly anomalous radioactivity up to 13,500 cps across the project.
Key findings include the discovery of previously undocumented radioactive occurrences and confirmation of favorable uranium host rocks. The company has collected 30 outcrop and boulder grab samples for analysis and plans to conduct a ground gravity survey in Q4 2025, followed by a maiden diamond drill program in Q1 2026.
The Corvo Project, located 60 km east of Cameco's McArthur River mine, shows historical uranium mineralization along an 800-metre strike length, with previous drill holes showing grades up to 0.065% U3O8.
