Standard Uranium Announces Completion of Summer Drill Program at Flagship Davidson River Project, Summary of Initial Assay Results and Annual General Meeting Results

VANCOUVER, Nov. 09, 2021 - Standard Uranium Ltd. ("Standard Uranium" or the "Company") (TSX-V: STND) (OTCQB: STTDF) (Frankfurt: FWB:9SU) is pleased to announce the completion of the Phase II summer 2021 diamond drilling program at the Company's flagship 25,886 hectare Davidson River Project (the "Project" or "Davidson River"). The Project is located in the Southwest Athabasca Uranium District of Saskatchewan, approximately 25 km to 30 km, respectively, to the west of Fission Uranium's Triple R and NexGen's Arrow deposits. This news release includes initial geochemistry (assay) results from the Company's summer drill program, showing elevated radioactivity discovered in the Saint, Warrior and Bronco trends. Final results from the Company's summer drill program are expected in six to eight weeks time.

Davidson River Summer Drilling Campaign Completed

The Davidson River Phase II summer drill campaign officially wrapped up on October 31, 2021. The Company completed thirteen (13) drill holes comprising 3,828 metres of diamond drill core across all four of the major conductive trends on the Project. Several high-priority geophysical drill targets were successfully intersected along the Saint, Warrior and Bronco trends.

Jon Bey, President and CEO stated: "Despite challenging conditions, we have intersected some of the most prospective basement structure and alteration to date along the Bronco and Warrior trends, in addition to zones of elevated radioactivity associated with reactivated structures and pegmatitic basement rocks."

Davidson River Summer Results Summary

The summer portion of the Phase II program on the Project successfully followed up on basement structural zones associated with hydrothermal alteration and anomalous geochemical signatures, in addition to exploring high-priority geophysical targets along the previously untested Bronco and Thunderbird trends.

Highlights from the Phase II summer program on the Project include:

Rock types and structure

• Several zones of elevated radioactivity were intersected across the Saint, Warrior and Bronco trends, associated with sheared and pegmatitic basement rocks. A summary of handheld RS-125 scintillometer peaks greater than 300 counts per second (cps) is presented in Table 1;
• Multiple zones of fault gouge and fault breccia associated with strong clay, chlorite and hydrothermal hematite were intersected along the SE Warrior trend in hole DR-21-025A (Figure 1);
• Deep seated, strongly graphitic structural zones were intersected within all four drill holes on the Bronco trend, exhibiting 1.3 km of continuity along strike between holes DR-21-027, -031 and -028 (Figure 1); and
• Stacked structures exhibit evidence of brittle reactivation in shear zones and hydrothermal fluid flow through fault conduits along Bronco and Warrior trends.

Sean Hillacre, Vice President of Exploration commented: "The strongly graphitic and clay-altered basement structures intersected along the SE Warrior and Bronco trends this season are exactly what we are looking for to host uranium mineralization on the Project. We have continued to build on the knowledge gained from our first two drill programs and continue to intersect more intensely reactivated structures associated with the alteration types that we want to see. In addition, the continuity along strike of the reactivated graphitic structures continues to validate our geological model, and it's exciting to see an increase in frequency of intervals hosting elevated radioactivity, especially within these structures."

Geochemistry Highlights

• DR-21-022
  • Anomalous U (14.2 ppm) associated with moderate graphite and strong sulphides within a sheared pyrrhotite-rich gabbroic gneiss from 337.75 to 337.85 m. Anomalous Cu (329 ppm), elevated Co (65.4 ppm) and S (3.76 wt%) were also returned.
• DR-21-023
  • Elevated U (5.78 ppm) and B (141 ppm) returned from paleoweathered semi-pelitic gneiss from 180.0 to 180.1 m. Anomalous Co (84.4 ppm) and Ni (368 ppm) also returned.
• DR-21-024
  • Elevated U (6.06 ppm) from 362.7 to 363.7 m within a graphitic shear zone displaying strong sulphide mineralization. Anomalous Cu (533 ppm), Co (122 ppm), and S (3.7 wt%) also returned.
• DR-21-025A
  • Anomalous B (283 ppm), Mo (35.9 ppm), Cu (300 ppm), Co (74.4 pp,), Ni (238 ppm), S (9.23 wt%), Fe₂O₃ (18.4 wt%), and V (280 ppm) from 264.0 to 264.5 m within a mylonitic graphitic semi-pelitic gneiss.
• DR-21-026
  • Anomalous U (149 ppm) and Th (1,530 ppm) and elevated B (136 ppm) from 154.4 to 154.5 m within orthogneiss directly below the unconformity at 152.1 m.
• DR-21-027
  • Within a graphitic shear zone from 421.0 to 423.0 m, elevated U (3.48 - 7.86 ppm) and Th (328 - 1,040 ppm) was returned, as well as anomalous Pb (43.3 - 92.4 ppm). The sample interval also returned elevated Rare Earth Elements (REE; Ce values from 1,140 to 3,430 ppm) and alkaline elements, which suggests widespread alkaline metasomatism. The Patterson Lake corridor also hosts prevalent alkaline igneous rocks and related metasomatism which has been linked to deep-seated structures. A similar geological setting may thus be evident on the Bronco Trend.
• DR-21-028 to 031 results are expected in six to eight weeks and will be announced when they are available.

Table 2. Summer Phase II 2021 drill holes, Davidson River Project. Collar coordinates are reported in NAD83 datum, Zone 12N; EOH = End of hole; TN = True North; *Restarted or abandoned.

One drill hole was abandoned and re-collared successfully, while four holes were abandoned due to difficult drilling conditions.

Drill core samples from the summer program 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. Uranium and all other assays in this news release are reported as total digestion. 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. Fire assay samples are chosen based on geological features and comprise 0.5 to 1.0 m split samples in areas of interest. 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.
