Standard Uranium Announces Final Analytical Results at Flagship Davidson River Project and High-Grade Uranium Assays from Sun Dog Project Grab Samples

VANCOUVER, Feb. 01, 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 II summer 2021 diamond drilling program at the Company's flagship 25,886-hectare Davidson River Project ("Davidson River"). The Davidson River Project is situated in the Southwest Athabasca Uranium District of Saskatchewan, approximately 25 km to 30 km, respectively, to the west of Fission Uranium's Triple R deposit and NexGen's Arrow deposit.

The Company is also pleased to announce high-grade¹ uranium assays returned from surface grab samples collected during a site visit on October 14^th, 2021, at its 15,770-hectare, 100% wholly owned, Sun Dog Project ("Sun Dog"). Sun Dog is located at the northwestern edge of the Athabasca Basin, Saskatchewan, and is south of the first uranium mining camp in Canada, the Beaverlodge District, near Uranium City.

¹ The Company considers uranium mineralization with concentrations greater than 1.0 wt% U3O8 to be "high-grade".

Jon Bey, President and CEO stated: "Our flagship Davidson River Project continues to provide us with key technical information that gets better with each drill program. Our goal is to make a high-grade basement hosted discovery and we are excited and committed to building on these results when we return to drill the 4^th program this spring. Prior to returning to Davidson River, we will drill our inaugural program at our 100% owned Sun Dog project near Uranium City this March. Based on the assay results from recent grab samples, we are enthusiastic to evaluate the initial drill core from this highly prospective region."

Key Focus Points

• Final results are presented for the remaining 3 holes of the 11-hole summer program; and confirm geochemical pathfinder elements near altered and sheared basement structures that were observed in the drill core.
  
  
• The Information from the 2020-2021 drilling has added to the geological framework of the property and has added the Company's confidence in continued drilling, which is scheduled for this spring and summer.
  
  
• Additional high-grade sampling from boulder grab samples at the Sun Dog Project confirms the motivation to proceed with the winter exploration program of a UAV magnetic survey, ground gravity survey and an inaugural drilling program.
  

Davidson River - Final Analytical Results from Summer 2021 Program

The summer portion of the Davidson River Phase II program comprised thirteen (13) drill holes totalling 3,828 metres of diamond drill core across all four of the major conductive trends on the Project (Figure 1), revealing high priority follow up targets for the 2022 spring/summer drill program.

Geochemistry Highlights

• Results of summer 2021 holes DR-21-020 to DR-21-027 were previously released on November 9^th, 2021.
• DR-21-028:
  • Anomalous U (14.0 ppm) from 350.0 to 350.5 m associated with a pegmatitic melt zone and minor clay-carbonate fault gouge. The sample interval also returned elevated Rare Earth Element ("REE") values including 798 ppm Ce, 293 ppm La, 259 ppm Nd, and 68.3 ppm Pr. Anomalous alkaline element compounds and Ba (2,600 ppm) were also returned, correlating with the elevated REE returned in hole DR-21-027 southeast along strike of the Bronco trend.
• DR-21-029 & 029A: Hole restarted and abandoned
• DR-21-030:
  • Elevated U (5.46 ppm) and B (104 ppm) within a chloritized fault breccia from 95.0 to 96.0 m.
  • Anomalous U (10.9 ppm) from 182.0 to 182.5 m within a carbonate-chlorite crackle breccia in altered granodioritic gneiss.
  • Anomalous U (20.0 ppm) and elevated pathfinder elements including V (226 ppm), Cu (50.0 ppm), and Ni (82.3 ppm) from 369.5 to 370.0 m within chlorite-sericite altered granodioritic gneiss.
• DR-21-031:
  • Several elevated U intercepts throughout the hole with maximums of 7.88 ppm and 7.87 ppm from 214.5 to 215.0 m and 356.5 to 357.0 m, respectively. The interval from 356.5 to 357.0 m also returned elevated pathfinder elements including Mo (17.7 ppm), Cu (390 ppm), and Co (63.4 ppm). Several of the elevated intercepts are associated with reactivated basement structure and local alteration and veining.

Sun Dog - Skye Target Grab Sample Analytical Results

In October 2021, four additional surface boulder grab samples were collected from the Skye target area (Figure 4) during a site visit by President and CEO, Jon Bey, and VP Exploration, Sean Hillacre, which have returned high-grade¹ uranium assays of 1.08 wt% U₃O₈, 1.55 wt% U₃O₈, 2.54 wt% U₃O₈, and 2.95 wt% U₃O₈. During the planned winter 2022 drill program, the Skye target area will be the first to be drill-tested for additional high-grade uranium mineralization at depth, following up on historical drilling and high-priority geophysical targets along conductor strike.

The inaugural Sun Dog drill campaign is on track to begin in early March 2022 and will focus on several high-priority target areas (Skye, Haven, Java) along several kilometres of untested graphitic conductors coincident with cross-cutting faults and historical intersections of high-grade uranium mineralization. The perched uranium mineralization present in the Athabasca sandstone outcrop on Sun Dog has never been properly tested at depth, and the Company aims to discover the high-grade "roots" of these mineralizing systems in the basement rocks underlying the mineralized sandstones.

Figure 4. Plan map of Sun Dog highlighting historical drill holes, geophysical conductors, and high-priority drill target areas is available at https://www.globenewswire.com/NewsRoom/AttachmentNg/bcfe6296-cbe3-4965-be1a-0eb2c739eb67. Grab samples noted in this release were taken from the Skye target area.

High-resolution ground gravity and UAV magnetic surveys will be completed over Sun Dog drill target areas during February 2022, and geophysical crews mobilized to the Uranium City area on January 19^th. All key vendors have been secured including local ice road contractors who will be constructing access roads and drill pads over the coming weeks leading up to drill mobilization in the last week of February.

Sean Hillacre, Vice President of Exploration commented: "The strongly graphitic and clay-altered basement structures intersected in the final holes of the summer season along the Bronco trend have the technical team more excited about Davidson River than ever. We are quickly and efficiently testing our major conductors and continue to see exactly what we are looking for to host uranium mineralization on the Davidson River Project. Additionally, the high-grade uranium results from the Sun Dog samples collected during my first trip to the Sun Dog Project continue to build anticipation for our inaugural drill program in March 2022. The confirmed presence of perched uranium mineralization in the outcropping sandstones at Sun Dog bodes extremely well for potential discovery of a significant uranium system that may be contained in the basement rocks below."

Samples collected for analysis are 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 %). All samples were tested with the Au1 gold by fire assay (reported in ppb and converted to g/t where appropriate). 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.
