Vancouver, British Columbia, November 06, 2025 — Standard Uranium Ltd. (“Standard Uranium” or the “Company”) (TSX-V: STND) (OTCQB: STTDF) (Frankfurt: FWB:9SU0) is pleased to outline extensive exploration plans for 2026 and present a summary of successful 2025 exploration activities. Exploration plans in 2026 will include high-resolution geophysics and targeted drill programs across multiple uranium projects in the Athabasca Basin, northern Saskatchewan.
Highlights:
- Drilling All Year – Diamond drilling programs are planned across multiple projects in 2026, including the Company’s flagship Davidson River project, and partner-funded programs on the Corvo and Rocas projects.
- Driving Discoveries – With programs planned across multiple Athabasca uranium projects across the Basin, the Company will generate constant news flow, cash payments in operator fees, and multiple chances at new discoveries in 2026.
- Building Value – The Company will drive meaningful exploration and build shareholder value through exploration on Davidson River while partner-funded programs provide additional exploration upside and minimize investor risk and dilution.
- Available Projects – The Company has multiple exploration stage projects still available for Joint Venture (“JV”) opportunities. Standard Uranium’s unique turn-key style JV model is attractive to exploration companies looking to enter the Saskatchewan uranium market – The Company’s technical team operates the entire project from start to finish including permitting, vendor management, First Nations agreements, and exploration programs.
Jon Bey, CEO of Standard Uranium, commented, “2026 is poised to be the Company’s most active exploration season to date. With new option agreements in place for the Corvo and Rocas projects, and Davidson River now drill-ready with new high-priority target areas identified via the first Exosphere Multiphysics survey in the southwestern Athabasca, we are pleased to share that we continue to advance our uranium exploration portfolio toward discovery. We firmly believe the nuclear and uranium markets will remain two of the top performing sectors in the investment landscape ahead.”

2026 Exploration Plans
Davidson River Project
New and refined target areas across the Warrior, Bronco, and Thunderbird conductor corridors have been identified through high-resolution 3D imaging of basement structures and potential alteration zones, providing key targeting information for spring 2026 drilling. The Company has secured all drill permits, signed Exploration Agreements with its Clearwater River Dene Nation (“CRDN”) partners, retained all essential vendors, and plans to initiate an aggressive drill program in early spring 2026 to begin testing new targets with approximately 8,000 metres planned.
Corvo Project
In December 2025, the Company plans to complete an extensive 50 m x 200 m ground gravity survey covering more than 29 km of conductive strike length, which will aid in identifying density anomalies that may represent hydrothermal alteration systems when coinciding with uranium fertile EM conductor trends.
Following the gravity survey, 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 newly-identified radioactive occurrences across the property.
Rocas Project
The Company completed a high-resolution ground gravity survey in 2024, and Convolutions Geoscience completed the processing, interpretation, and modeling of the gravity data. The survey identified several density-low anomalies coinciding with historical surface mineralization, lakebed geochemical anomalies, and cross-cutting fault zones along the Project’s known conductive exploration trends.
Standard Uranium plans to conduct the first-ever drill program on the Project in winter 2026, comprising approximately 1,800 metres, to begin testing high-priority zones along the main 7.5-kilometre magnetic low/EM conductive corridor which hosts several uranium showings and has remained untested to date.
Sun Dog Project
The Company plans to complete 3D modeling and inversions of EM and gravity data collected across the project in 2024 and 2025. Integration of geophysical products with surficial sampling and drilling results to date will help refine drill targets for a future partner-funded drill program.
2025 Exploration Summary
Davidson River Project
In May of 2025, a Fleet ExoSphere Multiphysics Survey was competed across key areas of the Thunderbird, Bronco, and Warrior trends. Combined 3D Ambient Noise Tomography (“ANT”) and Horizontal-to-Vertical Spectral Ratio (“HVSR”) velocity models and constrained ground gravity block models have been generated1.
Distinct gravity-low anomalies interpreted as potential hydrothermal alteration zones have been identified across all three corridors. These overlap known EM conductors, extrapolated basement faults from previous drilling, and basement velocity lows – indicating structural disruption or favorable lithological contrasts. Several new targets also align with ALS GoldSpot EM SmartMatch anomalies generated through machine-learning comparisons to the neighbouring Arrow and Triple R uranium deposits.

Sun Dog Project
In early 2025, MWH Geo-Surveys (Canada) Ltd. completed high-resolution ground gravity surveys across the Armbruster South, Wishbone, and McNie target areas, refining high-priority drill targets by identifying potential hydrothermal alteration zones associated with EM conductors.
Third-party processing of the gravity data by Convolutions Geoscience identified density-low bullseyes and high-contrast gravity zones. Where these anomalies coincide with faults, EM conductors, surface uranium showings, and lakebed geochemical anomalies, multiple new prospective target zones have been defined. Additionally, assays from the 2024 drill program, which tested the newly identified Wishbone target area, returned anomalous uranium in all eight drill holes2.
The Sun Dog Project is currently under a three-year earn-in option agreement with Aero Energy Ltd. (TSX-V: AERO).

We find the fuel to power a clean energy future
Standard Uranium is a uranium exploration company and emerging project generator poised for discovery in one of the world’s premier uranium districts. The Company holds interest in over 235,435 acres (95,277 hectares) in the Athabasca Basin in Saskatchewan, Canada. 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 ten 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 43,185 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.
