Leveraging modern survey techniques towards a new high-grade uranium discovery
Vancouver, British Columbia--(Newsfile Corp. - May 22, 2025) - Standard Uranium Ltd. (TSXV: STND) (OTCQB: STTDF) (FSE: 9SU) ("Standard Uranium" or the "Company") is pleased to announce the commencement of the first ExoSphere Multiphysics survey in the southwest Athabasca Basin region at its flagship Davidson River Project ("Davidson River", or the "Project"). Davidson River covers 30,737 hectares of prime exploration real estate in the SW Athabasca Uranium District, highly prospective for basement-hosted uranium deposits along trend from high-grade* uranium deposits under development (Figure 1). The surveys will be completed in partnership with Fleet Space Technologies Canada Corp. ("Fleet Space") across three exploration corridors in May-June 2025.
Highlights:
-
First Multiphysics in SW Athabasca: Standard Uranium and Fleet Space will complete the first three ExoSphere Multiphysics surveys in the prolific SW Athabasca Uranium District on Davidson River.
-
Poised for Discovery: High-priority target areas across three conductor corridors will be significantly derisked with high-resolution 3D imaging of basement structures and alteration zones, providing key targeting information for a follow up drill program.
-
Integrative Exploration Strategy: Combined real-time 3D Ambient Noise Tomography ("ANT"), Horizontal-to-Vertical Spectral Ratio ("HVSR"), and ground gravity surveys will provide new data layers to characterize lithological variations and identify potential alteration signatures related to uranium mineralization, in addition to further refining the structural architecture of known basement conductors.
-
Target Development & Drilling: The results of the Multiphysics surveys will be subject to geophysical interpretation and modelling, and integrated with the Project's existing drilling and geophysical datasets, to prioritize target areas for summer 2025 drilling.
"We are extremely excited to get back on the ground at our crown jewel project, Davidson River," said Sean Hillacre, President & VP Exploration of Standard Uranium, "Integrating the 3D density and velocity models to image alteration systems in the basement rock could provide the key data we've been looking for to vector into a new discovery at Davidson. We have been hard at work developing targets across the Project since 2022 and armed with the new datasets from the Multiphysics system, we aim to expedite discovery of a new basement-hosted uranium system with drilling this year."

Davidson River Multiphysics Surveys
In partnership with Fleet Space, the Company will undertake three ExoSphere Multiphysics survey grids across the Warrior, Bronco, and Thunderbird conductors on the Project (Figure 2). The Company and Axiom Exploration Group Ltd. will mobilize to deploy the survey grids in late May, and the survey is anticipated to take approximately 35 days to complete.
The Multiphysics surveys will collect and integrate ANT, HVSR, and ground gravity datasets covering highly prospective areas along three of the four main structural corridors on the Project. The surveys will provide critical targeting layers in the form of 3D ANT-HVSR shear velocity models and custom inversion models for subsurface density, leveraging both passive seismic and ground gravity datasets as inputs.
Using Fleet Space's proprietary Cover Depth analysis from the ANT data in combination with the ground gravity data, Fleet Space will compute and provide a cover-corrected gravity dataset which will significantly upgrade target areas at Davidson River through imaging of density anomalies in the basement rock. These surveys will be the first of their kind in the SW Athabasca Basin uranium district and marks a significant step towards discovery on the Project.
Density anomalies in the basement rock coinciding with known graphitic conductors are often indicative of potential zones of hydrothermal alteration of host rocks associated with uranium mineralization events. Drill targeting with this strategy has been proven through the discovery of world-class uranium deposits in the SW Athabasca Basin and will upgrade targets across the Project.
Following post-survey data analysis and integration, the Company plans to execute a diamond drill program to begin testing the highest priority targets across all three surveyed conductor corridors. Drilling is planned to be completed this summer, marking the first drill program on the Project since 2022. Positive results from previous drill campaigns will be integrated into drill targeting with the newly acquired Multiphysics data.
About Davidson River
Davidson River is Standard Uranium's flagship property, located in the southwest Athabasca Uranium District of the Athabasca Basin, Saskatchewan, and encapsulates the inferred extension of the structural trend that hosts the Triple R and Arrow uranium deposits (Figure 1). The Project consists of 10 contiguous mineral dispositions totaling 30,737 hectares and lies approximately 25 to 30 km west of Arrow and Triple R and 75 km south of the past-producing Cluff Lake uranium mines. The Company has completed 16,561 metres of diamond drilling in 39 drill holes on the Davidson River property since 2020, which has further refined the exploration strategy for high-grade basement hosted uranium mineralization on the property3.
Davidson River hosts four main conductive corridors - the Warrior, Bronco, Thunderbird, and Saint trends (Figure 2). These conductive trends are associated with graphitic-sulphidic structures in basement rocks, which are commonly associated with high-grade* uranium systems, providing the conduits for mineralizing fluids. This concept has been proven for all four corridors, with several instances of graphitic-sulphidic fault rocks and reactivated structures intersected along the tested strike length.
Favorable basement rock types and alteration phases have been observed across the strike length of the main trends, resembling those which host other uranium deposits in the southwestern Athabasca Basin region. Key indicators include clay-dravite alteration and stacked lenses of variably strained graphite and sulphide-bearing garnetiferous gneisses and altered feldspar-rich rocks. Structural zones in the basement are locally associated with elevated uranium and/or boron values (over 1,000 ppm B), such as in DR-20-009 and -0113.
The results from diamond drilling programs to date highlight the potential for the Davidson River Project to host significant basement hosted unconformity-related uranium mineralization, and the property contains several priority targets along all four trends that warrant further exploration.

*The Company considers uranium mineralization with concentrations greater than 1.0 wt% U3O8 to be "high-grade".
**The Company considers radioactivity readings greater than 300 counts per second (cps) to be "anomalous".

About Standard Uranium (TSXV: STND)
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 the world's richest uranium district. The Company holds interest in over 233,455 acres (94,476 hectares) in the world-class 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 42,384 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.
