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.

The project's location, 75 kilometers southwest of the Key Lake Mine, and recent high-resolution ground gravity survey results from 2024 highlight potential for significant uranium exploration targets.
Standard Uranium (OTCQB: STTDF) has announced positive results from an airborne Time Domain Electromagnetic (TDEM) survey at its 12,265-hectare Corvo Uranium Project in Northern Saskatchewan. The survey, completed between February and March 2025, confirmed 29 kilometers of prospective conductor strike length across the project.
The company completed a detailed mapping and sampling program in July 2025, with samples sent to Saskatchewan Research Council Geoanalytical Laboratories. The Project, located near Cameco's McArthur River mine, shows potential for high-grade basement-hosted uranium mineralization, with historical surface samples showing up to 59,800 ppm uranium at the Manhattan Showing. A maiden diamond drill program is planned for Q1 2026.
Standard Uranium (OTCQB: STTDF) has completed the first-ever ExoSphere Multiphysics survey in the southwestern Athabasca Basin on its Davidson River Project in Saskatchewan. The company, in partnership with Fleet Space Technologies, conducted surveys across three major conductor corridors: Warrior, Bronco, and Thunderbird.
The comprehensive program combines three advanced geophysical technologies: 3D Ambient Noise Tomography (ANT), Horizontal-to-Vertical Spectral Ratio (HVSR), and ground gravity surveys. These surveys aim to identify potential uranium mineralization zones and refine the structural architecture of known basement conductors.
The company plans to launch a diamond drill program this summer (August-September 2025), marking its first drilling campaign since 2022. The Davidson River Project spans 30,737 hectares of exploration territory in the uranium-rich Southwest Athabasca Uranium District.
