Standard Uranium Ltd (TSX-V:STND, OTCQB:STTDF) uncovered some of the highest uranium grades ever reported at its Corvo Project in Saskatchewan, signaling strong potential for future development.
Vice President of Exploration, Sean Hillacre, spoke with Proactive about the results, newly identified showings, and the company’s upcoming exploration plans.
Proactive: You’ve just reported some of the highest uranium grades ever recorded at the Corvo Project. What do these results tell you about the project’s potential, and how do they compare with historical findings in the area?
Sean Hillacre: That’s a great question. We’re really excited about what we’ve seen. We got boots on the ground earlier this summer for a prospecting, sampling, and mapping program, and the results have exceeded our expectations. Historically, the highest U₃O₈ grades at the Manhattan showing were around 7.2%, so we’re thrilled that we were able to sample the same area and return even higher values—up to 8.1% U₃O₈.
The rock types at Corvo look fantastic. As we mentioned in the release, we’re seeing a variety of rock types and deposit models, plus the added bonus of rare earth element concentrations. The geology is really interesting—seeing mineralized faults at surface and confirming those historical results is exceptional. We’re very excited to move the project forward and start drilling.
Your team also uncovered new radioactive showings and confirmed mineralization across multiple areas. Can you explain the geological significance of these discoveries and what makes Corvo such a promising uranium target?
That’s right. We identified several previously undocumented radioactive showings. The project saw a fair amount of exploration up until 1980, which was the last time it was drilled, and only limited modern work since then. So, being able to get out there and find numerous new showings across different rock types—pegmatite-hosted, metasedimentary-hosted, and gneiss-hosted uranium—is really exciting.
It speaks to the geological complexity of the area. We can clearly see the structural controls at surface, which is exactly what we’re looking for in a structurally and basement-hosted uranium system. The presence of radioactive boulders also reflects glacial transport and hints at multiple deposit types and mineralization zones across the project. All of that makes Corvo a very promising target.
You mentioned plans for a ground gravity survey in December and a drill program in early 2026. What are the key objectives of these programs, and what would success look like for Standard Uranium?
Since acquiring the project, we’ve partnered with Axiom Exploration, who flew a new electromagnetic survey earlier this year. That survey confirmed and extended the strike length of conductive zones—the plumbing system for uranium mineralization.
Now, the next step is to refine our drill targets through a gravity survey. Once the lakes freeze—likely by late November or early December—we’ll get crews on the ground to cover nearly 30 kilometers of strike length. The gravity data will help us identify alteration halos and density lows, which often correlate with uranium deposits or hydrothermal activity.
That information will allow us to pinpoint our first drill targets ahead of the initial drill program—the first on this property in about 40 years. Another advantage is infrastructure: the highway runs right through the southeastern corner of the project, so we’ll have excellent access and can keep drilling costs down. We’re really looking forward to testing these targets for the first time.
