Standard Uranium hits anomalous radioactivity in drilling at Davidson River

Standard Uranium Ltd (TSX-V:STND, OTCQB:STTDF, FRA:9SU0) has reported early results from its summer drill campaign at the Davidson River Project in Saskatchewan's southwest Athabasca Basin, with the first hole intersecting anomalous radioactivity and significant basement structures.
The first hole of the program, DR-26-040, on the Bronco corridor intersected three metres of anomalous radioactivity exceeding 300 counts per second, with peaks of 540, 780, and 1,650 cps between 464 and 466 metres depth. Both holes have encountered strongly graphitic basement structures associated with hydrothermal alteration including hematite and clay.
Drill targets for the campaign were prioritized across three of Davidson River's four major conductor corridors – Warrior, Bronco, and Thunderbird – following the first-ever ExoSphere Multiphysics surveys completed in the southwest Athabasca Basin region.
The company said integration of that data with existing drill results, ground gravity, electromagnetic conductors, and machine-learning targeting has upgraded its subsurface understanding of the project.
"Hitting elevated radioactivity and significant basement structures on the first hole of the drill program is exciting, but more than that, it increases our confidence in our new targeting datasets," said Sean Hillacre, president and vice president exploration of Standard Uranium.
"The integration of ExoSphere multiphysics data with our existing drill results, ground gravity, EM conductors, and machine-learning targeting has materially upgraded our understanding of the subsurface at Davidson River.”
Drilling is planned to continue through August 2026. The campaign is targeting uranium mineralization along regional structural trends that host NexGen Energy's Arrow deposit and Paladin Energy's Triple R deposit.
Davidson River covers 30,737 hectares. Drilling began June 1 with two rigs operating around the clock. The company has completed 900 metres across two in-progress holes on the Bronco and Thunderbird corridors.
