Standard Uranium to start inaugural drill program and completes ground gravity survey at Corvo Uranium Project, Saskatchewan

Standard Uranium Ltd. [TSXV: STND; OTCQB: STTDF; FSE: 9SU0] reported that drilling and mobilization plans have been finalized for the maiden drilling campaign on the Corvo Uranium Project, Saskatchewan. Additionally, the company announces the completion of an extensive high-resolution ground gravity survey across the project.

The project is currently under a three-year earn-in option agreement with Aventis Energy Inc. [CSE: AVE]. Under the Option Agreement, Aventis can earn a 75% interest in the project by funding CAD$6M in exploration expenditures over three years, with the inaugural drill program beginning in February 2026.

The company and Aventis reported that final planning is complete for the inaugural winter drill program on the project, situated in the prolific eastern Athabasca Basin region. Exploration teams will be mobilizing to the field in early February, ahead of schedule.

Highlights: Drill Plan Finalized: Approximately 2,500 – 3,000 metres planned across 8-10 drill holes, targeting shallow high-grade^* basement-hosted uranium mineralization.

Robust & Shallow Drill Targets: Drill plans comprise skid-supported diamond drilling focused on high-priority uranium targets refined by geophysical work completed by the company in 2025. Uranium target zones on the project lie within less than 200 – 300 metres below surface.

Untapped Uranium Potential: One diamond drill will focus on the highest-priority target area along the northern electromagnetic corridor, investigating the never-before-drilled Manhattan Showing (8.10% U₃O₈ at surface), coincident with modeled electromagnetic conductors for the first time.

Fully Funded: Aventis will be funding 100% of the program to meet the year-one expenditure requirements under the Option Agreement.

Key Vendors Secured: The company has engaged all key contracts for the program and diamond drilling crews will mobilize to the Corvo Project in January to begin constructing Project access.

“Our technical team and partners at Aventis are thrilled to begin drilling the exciting targets identified along more than 29 km of structural corridors on the Project for the first time, exploring for shallow high-grade uranium mineralization,” said Sean Hillacre, President & VP Exploration. “Our exploration thesis on the Project is directly analogous to the targeting strategies that lead to nearby discoveries in the Wollaston Domain such as the Rabbit Lake deposit and the GMZ and Ackio zones.”

2026 Exploration Programs: In late 2025, the Company contracted MWH Geo-Surveys (Canada) Ltd. (MWH) to complete an extensive 50 m x 200 m ground gravity survey covering more than 29 km of conductive strike length, designed to aid in identifying density anomalies that may represent hydrothermal alteration systems coinciding with uranium fertile electromagnetic (EM) conductor trends. MWH completed the geophysical grid in early January 2026, and the survey comprised more than 5,000 individual gravity measurement stations.

A skid-assisted diamond drill program totalling approximately 3,000 metres is planned for winter 2026, which will mark the first drill program on the project in more than 40 years. Drilling will target high-priority areas including the never-before-drilled Manhattan Showing and other newly-identified radioactive occurrences across the property. Outcrop grab samples collected earlier this year returned uranium assays reaching a maximum of 8.10% U₃O₈ at the Manhattan Showing.

The company believes the project is prospective for the discovery of shallow, high-grade^, basement-hosted uranium mineralization akin to the Rabbit Lake deposit and the recently discovered GMZ and Ackio zone. Located just outside the current margin of the Athabasca Basin, Corvo boasts shallow drill targets with bedrock under minimal cover of glacial till.

Standard Uranium holds interest in over 235,678 acres (95,375 hectares) in the Athabasca Basin, 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 highly 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 45,000 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, is comprised of nine mineral claims over 19,603 hectares. The Sun Dog project is 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.
