Standard Uranium Ltd. has announced preliminary results from its 2025 exploration programmes, the Corvo Uranium Project, currently under a three-year earn-in option agreement with Aventis Energy Inc. From July 4 to July 16, 2025, the Company completed a detailed mapping and sampling programme across historical uranium showings and zones of interest on the Project.
“Confirming strong radioactivity at multiple historical uranium showings on the Project and discovering undocumented showings speaks to the prospectivity of the Corvo Project. In addition, taking new samples will allow us to confirm uranium grades and build a comprehensive understanding of controls on mineralisation prior to our maiden drill programme,” said Sean Hillacre, President & VP Exploration of Standard Uranium. “We look forward to continuing to bolster our targeting strategy through further work programs planned on the Project in 2025.”
Beginning July 4 and concluding July 16, 2025, the Standard Uranium technical team completed a detailed mapping, prospecting, and sampling programme to ground-truth historical uranium showings at surface on the Project.
A total of 30 outcrop and boulder grab samples have been submitted to Saskatchewan Research Council Geoanalytical Laboratories in Saskatoon, SK for whole-rock, uranium, and REE geochemical analysis. Results will be released and incorporated into the first NI 43-101 technical report on the Project.
More than 160 detailed geological observations, structural measurements, and scintillometer readings were taken from several outcrops across the Project within the T-Lake, Dorward, Unnamed, Finger, Snout, Hook, and Sheppard Lake areas.
Prospecting confirmed several uraniferous outcrops and boulders across the Project, including the Manhattan showing (1.19 to 5.98% U3O8) and SMDI showing 2052 (0.137% U3O8 and 2,300 ppm Th)1. Off-scale radioactivity >65,535 counts per second (“cps”) was measured at the Manhattan showing (Figures 2 and 3).
A total of 112 handheld scintillometer readings of anomalous radioactivity >300 cps were recorded, including six measurements >10,000 cps at surface (Figure 4). Prospecting for radioactive boulders and outcrop was completed using handheld RS-120 Super-Scintillometers and RS-125 Super-Spectrometers manufactured by Radiation Solutions Inc.
At the Corvo Uranium Project, uranium mineralisation is present along a strike length of 800 metres in historical drill holes TL-79-3 (0.057% U3O8 over 3.5 m) to TL-79-5 (0.065% U3O8 over 0.1 m). Recent expansion of the Project adds multiple new data points of uranium anomalism in the south, including surface sample JBWLR011, returning 1,420 ppm U.
Future Exploration Plans
Supplementary geophysical surveys across the Project are being designed to further refine drill targets for an inaugural drill program. The Company plans to complete a high-resolution ground gravity survey across the main conductive trends on the Project, aiming to identify potential hydrothermal alteration halos which could be related to basement-hosted uranium mineralisation.
Earlier this year, the Company contracted Axiom Exploration Group Ltd. in partnership with New Resolution Geophysics to carry out a helicopter-borne Xcite time domain electromagnetic and total field magnetic survey over the Corvo Project2. The survey totalled approximately 1,380 line-kms with a traverse line spacing of 100 m and tie-line spacing of 1,000 m. The airborne TDEM survey outlines several kilometres of conductive anomalies and magnetic features in bedrock, effectively enhancing the resolution of more than 29 kilometres of conductive trends on the project.
The magnetic survey component of the TDEM survey contributes to definition of potential fault systems and structural trends not previously identified across the project related to historical uranium showings at surface and in historical drill holes.
Ongoing geophysical interpretation and modelling is being completed to integrate historical surveys with newly collected datasets, which will provide high-priority drill targets and significantly derisk the Project prior to modern drilling in 2026.
The Company believes the Project is highly prospective for the discovery of shallow, high-grade* basement-hosted uranium mineralisation akin to the Rabbit Lake deposit and the recently discovered Gemini Mineralised Zone. Located just outside the current margin of the Athabasca Basin, Corvo boasts shallow drill targets with bedrock under minimal cover of glacial till. Several outcrop showings of mineralised veins and fractures are present on the Project, notably the Manhattan Showing that returned historical sample results up to 59,800 ppm U at surface1 and has never been drill tested.
