Aventis Energy said on October 29, 2026, that surface exploration at the Corvo Uranium Project in northern Saskatchewan recorded radioactivity of up to 48,000 counts per second and identified a previously undocumented showing. Laboratory results are pending to determine uranium content.
Key Takeaways
- The highest reading came from the historical Manhattan East showing.
- A new showing on the Brooklyn trend recorded up to 13,400 counts per second.
- Nine grab samples are awaiting analysis, and a second drilling program is planned for 2027.
Corvo Uranium Project surface findings
Crews mapped, prospected and sampled the 12,363-hectare project from October 1 to 9. At Manhattan East, handheld instruments recorded readings of 20,000 to 48,000 counts per second in outcrop. A reading of 30,000 counts per second was recorded about 130 metres to the northeast.
Along the Brooklyn trend, the previously undocumented showing recorded up to 13,400 counts per second, while a known occurrence reached 36,000. Across the program, 56 readings exceeded the 300-counts-per-second anomalous threshold, including eight above 10,000.
What the readings do and do not show
Scintillometer readings are a preliminary indication of radioactive minerals, not a direct measure of uranium grade. Nine selected outcrop grab samples have been submitted to Saskatchewan Research Council Geoanalytical Laboratories for uranium, rare earth element and whole-rock analysis. Such samples may not represent the underlying mineralization.
The surface work followed a winter 2026 drilling program in which all nine completed holes returned anomalous uranium. One additional hole was abandoned because of ground conditions.
Exploration partnership and next steps
Aventis funded the surface work and Standard Uranium operated it under a three-year earn-in agreement. Standard Uranium’s fall exploration plan was designed to connect surface mapping and sampling with the earlier drilling results. Under the agreement, Aventis may earn a 75% interest in Corvo.
The companies plan to release the assay results after they are received and reviewed. Standard Uranium is designing geophysical surveys to refine targets for a second drilling program planned for 2027.
