Standard Uranium doubles Thunderbird structural corridor width at Davidson River Project

Standard Uranium Vice President of Exploration Sean Hillacre joined Steve Darling from Proactive to discuss additional geological findings and interpretations from the company's summer 2026 drilling program at its flagship Davidson River Uranium Project in Saskatchewan's Athabasca Basin.
Detailed core logging and updated structural modelling from the 6,734-metre program have doubled the modelled width of the Thunderbird structural corridor and identified dravite-clay alteration across the Warrior, Bronco and Thunderbird trends.
Hillacre told Proactive that the summer program consisted of 12 drill holes testing the three conductive trends. Since drilling wrapped up, the company's geological team has completed detailed logging of all drill core and updated its structural model. Whole-rock geochemical assay results are still pending.
Five drill holes tested the Thunderbird Trend over approximately 2.8 kilometres of strike length. Oriented core measurements identified shear zones striking north-northwest and dipping steeply to the southwest. At Bronco four drill holes intersected graphitic shear and fault zones that define a structural corridor approximately 250 to 400 metres wide.
The Bronco Trend has been tested over approximately 1.3 kilometres of strike, with structures dipping moderately to steeply toward the west-southwest.
The Warrior trend drilling intersected fault and shear zones, including a 5.3-metre fault breccia interval with local cataclasite and moderate to strong clay alteration in DR-26-049, between 474.95 and 480.25 metres.
The company plans to integrate the pending geochemical results with its updated structural model, alteration logging and geophysical data to prioritize follow-up exploration targets. Areas of interest include the Thunderbird and Bronco structural corridors, dravite-bearing structures along the Warrior Trend and more than 60 kilometres of untested conductive strike length across the broader project.
