Standard Uranium Announces Final Analytical Results from Summer Drill Program at Flagship Davidson River Project

Vancouver, British Columbia, November 08, 2022 — Standard Uranium Ltd. (“Standard Uranium” or the “Company”) (TSX-V: STND) (OTCQB: STTDF) (Frankfurt: FWB:9SU) is pleased to announce the final analytical results of the Phase III summer 2022 diamond drilling program at the Company’s flagship 20,006-hectare Davidson River Project (“Davidson River”). Davidson River is situated in the Southwest Athabasca Uranium District of Saskatchewan, approximately 25 km to 30 km, respectively, to the west of Fission Uranium Corp.’s Triple R deposit and NexGen Energy Ltd.’s Arrow deposit.

Key Focus Points:

• All 2022 drill holes intersected prospective graphitic structures in basement rocks in addition to favorable alteration zones.
• Analytical results returned elevated pathfinder elements in addition to locally elevated uranium and boron content in several drill holes.
• Aggressive step-outs have confirmed the continuity of wide structural zones along the Bronco and Thunderbird conductors.
• The southeast Bronco conductor hosts some of the most prospective basement structures intersected to date.
• Several kilometres of strike length remain untested on all four conductors, with high- priority drill targets identified.
• GoldSpot Discoveries Corp. (“GoldSpot”) will be providing supplementary targeting vectors for the planned 2023 drill program through data-driven AI technology.

Davidson River – Summer 2022 Drill Program Summary

The Davidson River Phase III program comprised ten (10) drill holes totalling 4,107.7 metres of diamond drilling along the Thunderbird and Bronco conductive trends (Figure 1). Significant structure and favorable alteration zones were intersected, defining high priority follow up target areas for the planned 2023 summer/fall drill program.

Deep seated and strongly graphitic basement structures along the Bronco and previously untested Thunderbird trend were successfully intersected in all drill holes completed during the 2022 exploration program. DR-22-033A and DR-22-037 host anomalous uranium as well as significant sulphide mineralization and elevated pathfinder elements. Additionally, and in conjunction with hydrothermal quartz, metasomatism, and remobilized graphite, a highly prospective limonite-hematite redox alteration zone was intersected 37 metres below the unconformity in Thunderbird drill hole DR-22-033A (Figure 2A).

The southeast portion of the Bronco trend hosts some of the most prospective basement structures intersected to date at Davidson River. DR-22-036 (Figure 2F, 2G) contains multiple stacked and reactivated graphitic shears with significant evidence of hydrothermal fluid flow, while the follow up hole, DR-22-038, contains anomalous uranium as well as clay-altered graphitic shearing, indicating that the along-strike continuity of the trend opens to the south along the conductor.

Drill hole intersections of prospective structure, alteration, and anomalous geochemical results have continued to improve with each drill program at Davidson River, setting the stage for the planned 2023 drill program to be the most exciting to date. Several high-priority drill targets have been outlined through integration of targeting vectors, which will be further supplemented by work completed by GoldSpot prior to the drill program slated to begin in June 2023.

Sean Hillacre, Vice President of Exploration, commented: “The Davidson River Project continues to deliver exciting and encouraging results with each drill program as we search for high-grade basement hosted uranium mineralization. The alteration zones and structure intersected during the 2022 drill program are just the ingredients we want to see, and we will be utilizing these promising results in concert with GoldSpot’s cutting-edge technology to continue exploring in 2023.”

Core photos and cross-sections highlighting prospective structural zones associated with elevated uranium and/or pathfinder elements are presented in Figure 2 and Figure 3. A summary of highlights of geochemical anomalism for each drill hole is included below.

Schematic cross-sections through the Thunderbird and Bronco trends are provided in Figure 3 and Figure 4, highlighting selected drill holes from the summer 2022 drill program. Highlighted drill hole traces are projected to section and displayed with partial digestion uranium assays in parts per million (“ppm”) >5.0 ppm and gamma probe peaks annotated.

*The Company considers uranium mineralization with concentrations greater than 1.0 wt% U3O8 to be “high-grade”.

Samples collected for analysis were sent to Saskatchewan Research Council Geoanalytical Laboratories (“SRC”) in Saskatoon, Saskatchewan for preparation, processing and ICP-MS multi- element analysis using total and partial digestion, gold by fire assay, and boron by fusion. Sandstone samples were tested using the ICP-MS1 uranium multi-element exploration package plus boron. Basement samples were tested with ICP-MS2 uranium multi-element exploration package plus boron. All sandstone samples, and basement samples marked as radioactive upon arrival to the lab were also analyzed using the U3O8 assay (reported in wt %). Basement rock split interval samples range from 0.1 to 0.5 m and sandstone composite samples are comprised of multiple equal sized full core “pucks” spaced over the sample interval. SRC is an ISO/IEC 17025/2005 and Standards Council of Canada certified analytical laboratory. Blanks, standard reference materials, and repeats were inserted into the sample stream at regular intervals in accordance with Standard Uranium’s quality assurance/quality control (QA/QC) protocols.

The scientific and technical information contained in this news release, including the sampling, analytical and test data underlying the technical information contained in this news release, has been reviewed, verified, and approved by Sean Hillacre, P.Geo., VP Exploration of the Company and a “qualified person” as defined in NI 43-101.

About Standard Uranium (TSX-V: STND)

We find the fuel to power a clean energy future

Standard Uranium is a uranium exploration company with a focus on the world-class Athabasca Basin in Saskatchewan, Canada. Since its establishment, Standard Uranium has focused on the identification 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 seven mineral claims over 20,006 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 support provide significant confidence in the exploration model and future success is expected.
