Standard Uranium to drill Corvo Project, including high-grade Manhattan Uranium showing, Saskatchewan
Standard Uranium Ltd. [TSXV: STND; OTCQB: STTDF; FSE: 9SU0] reported that mobilization is underway for the maiden diamond drilling campaign at its Corvo Uranium Project, located in the eastern Athabasca Basin region, Saskatchewan. The winter 2026 program will focus on the Manhattan Showing, an area characterized by significant surface mineralization with outcrop grab samples returning up to 8.10% U3O8 along a NE-SW trending electromagnetic (EM) corridor coincident with low-density anomalies.
The project is currently under a three-year earn-in option agreement with Aventis Energy Inc. [CSE: AVE]. Under the option agreement, Aventis has been granted an option to earn a 75% interest in the project by funding CAD$6M in exploration expenditures over three years, with the inaugural drill program beginning next week.
2026 Corvo Drill Program Highlights – Mobilization & Site Access Initiated: Base diamond drilling personnel have begun road construction to establish property access. The drilling crew is currently finalizing preparations and is scheduled to be enroute to the site by the end of this week.
High-priority shallow drill targets identified: The drill program will comprise approximately 3,000 metres of skid-supported diamond drilling, partitioned across eight to 10 drill holes. Operations will focus on high-priority uranium targets, which were rigorously refined through integration and interpretation of the company’s 2025 high-resolution geophysical surveys and historical data.
Drilling to test high-grade Manhattan Showing: For the first time, the company will drill test the Manhattan Showing, which returned a maximum surface sample grade of 8.10% U3O8. This priority target is characterized by a confluence of mineralization, EM conductors, and newly defined density anomalies – classic signatures of Athabasca-style uranium mineralization. Additionally, the upcoming program is designed to explore the untapped potential of the northwestern EM corridor, which extends along strike from the showing for several kilometres.
“Getting the drills turning at Corvo is a major milestone for Standard and our partners at Aventis Energy, notably as we will test the high-grade Manhattan Showing at depth,” said Sean Hillacre, President & VP Exploration. “By combining the surface mineralization of 8.10% with our newly defined gravity lows and EM conductors, we have clear, high-priority targets that fit the classic signature of unconformity-related uranium deposits. With the support of our partners at Aventis, our team is eager to see what this northwestern corridor holds as we apply a rigorous, discovery-focused approach to this inaugural program.”
Natural gamma radiation from rocks reported in this news release was measured in counts per second (cps) using a handheld RS-125 super-spectrometer and RS-120 super-scintillometer.
Standard Uranium holds interest in over 241,652 acres (97,793 hectares) in the Athabasca Basin of Saskatchewan. Since its establishment, Standard Uranium has focused on the identification, acquisition, and exploration of Athabasca-style uranium targets with a view to discovery and future development.
Standard Uranium’s Davidson River Project, in the southwest part of the Athabasca Basin, Saskatchewan, comprises 10 mineral claims over 30,737 hectares. Davidson River is prospective for basement-hosted uranium deposits due to its location along trend from recent high-grade uranium discoveries.
However, owing to the large project size with multiple targets, it remains broadly under-tested by drilling. Recent intersections of wide, structurally deformed and strongly altered shear zones provide significant confidence in the exploration model and future success is expected.
Standard Uranium’s eastern Athabasca projects comprise over 53,166 hectares of prospective land holdings. The eastern basin projects are highly prospective for unconformity related and/or basement hosted uranium deposits based on historical uranium occurrences, recently identified geophysical anomalies, and location along trend from several high-grade uranium discoveries.
Standard Uranium’s Sun Dog project, in the northwest part of the Athabasca Basin, Saskatchewan, is comprised of nine mineral claims over 19,603 hectares. The Sun Dog project is highly prospective for basement and unconformity hosted uranium deposits yet remains largely untested by sufficient drilling despite its location proximal to uranium discoveries in the area.
