Standard Uranium Completes Winter Drill Program at Sun Dog

Press Release

Vancouver, British Columbia, April 12, 2022 — Standard Uranium Ltd. (“Standard Uranium” or the “Company”) (TSX-V: STND) (OTCQB: STTDF) (Frankfurt: FWB:9SU) is pleased to announce that the winter drill program at its 100% owned Sun Dog Project (“Sun Dog” or “the Project”) has been successfully completed. 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.

Key Focus Points:

  • Sun Dog diamond drill program successfully executed, totalling 1,242.3 metres (m) within 4 drill holes.
  • Phase-one drilling intersected several characteristics of a uranium-bearing mineralized system.
  • High-resolution ground gravity and UAV magnetics geophysics identified several new high priority targets.
  • Follow-up drill holes are planned to be tested during a Phase-two winter 2023 program.

The inaugural drill program at Sun Dog tested three of the four intended target areas in the face of safety related time constraints due to the anticipated early deterioration of the ice road conditions. Four drill holes were completed in three target areas for a total of 1,242.3 m (Table 1). In addition, the Company successfully completed high-resolution ground gravity and UAV magnetic surveys across the Skye, Haven, Johnston Bay (J-Bay), and Java target areas on the Project, further refining high-priority drill target areas across the 15,770-hectare property (Figure 1). These surveys add further geological context to the drill targets which are locally following up on known high-grade1 uranium mineralization.

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

Jon Bey, CEO and Chairman stated: “I want to thank everyone involved in making this drill program happen. The logistics were challenging but we managed to complete four holes in three target areas and gather excellent data which will help plan future drill programs in this region. We look forward to shifting our focus to our flagship Davidson River Project and drilling our fourth program in the Southwest Athabasca Uranium district starting in mid May.”

Sun Dog – Winter 2022 Drill Program Highlights

  • SD-22-001; Haven target (Figure 2):
    • 325 m step out from known surface mineralization at Haven
    • Intersection of several hydrothermal quartz-hematite breccia structures ranging from 1.0 to >10.0 m in drill hole thickness – Strong hydrothermal fluid flow
    • Intersection of possible dravite(?)-quartz hydraulic breccia from 320.0 to 320.3 m – Dravite to be confirmed through spectroscopic analysis
    • No significant radioactivity
  • SD-22-002; J-Bay target (Figure 3):
    • 543 m step out SW along strike from known mineralization
    • Intersection of highly deformed graphitic metapelite, quartz-hematite and limonite hydrothermal breccias
    • No significant radioactivity
  • SD-22-003; J-Bay target (Figure 3):
    • 450 m step out NE along strike from known mineralization
    • Intersection of deformed graphitic metapelite lenses overprinted by hydrothermal quartz-hematite breccias
    • Elevated radioactivity from 164.5 to 167.0 m, up to 300 counts per second (“cps”), associated with graphite-hematite fractures in metapelite
  • SD-22-004; Java target (Figure 4):
    • 330 m step out NW along strike from known mineralization
    • Altered orthogneiss units with metre-scale brittle structures
    • No significant radioactivity

The inaugural winter drill program was designed to begin following up on known uranium mineralization on the Project, with the aim of vectoring towards high-grade “roots” within basement rocks underlying the Athabasca sandstones. Although cut short due to weather conditions, the first pass of drilling revealed rock types, structures, and alteration that are favorable and indicative of the appropriate environment for uranium mineralization.

Priority follow up targets have been planned and are slated to be drilled in 2023 during a larger-scale drill program during the relatively short winter drilling window. Continuing exploration plans for the project include a detailed bedrock mapping and sampling program in Q3 2022, leading into a two-drill exploration program in winter 2023.

Sean Hillacre, Vice President of Exploration commented: “The technical team and I are very encouraged by the results of our first reconnaissance-scale program on Sun Dog. The scale and intensity of deformation we are seeing in our first handful of holes is spectacular, and coupled with the alteration types intersected, we are confident it is only a matter of time until we vector into something even more exciting. I have personally observed the same types of hydrothermal breccias proximal to high-grade uranium deposits in other areas of the Basin, which gets me excited for continued exploration on the project. Additionally, we are eager to get back up to Sun Dog next winter as we’ve learned how to better streamline many logistical components of the program and have plans to expand our drill arsenal to make the most of our ever-changing weather window.”

Drill core samples from all Sun Dog drill holes have been submitted to the Saskatchewan Research Council (“SRC”) Geoanalytical Laboratory in Saskatoon, Saskatchewan, for whole-rock, multi-element and U3O8 analyses. Geochemical assay results will be released as they are received and examined by the technical team in accordance with the Company’s internal quality control process.

The Company is now preparing to mobilize and begin the fourth drill program on its flagship Davidson River Project (“Davidson River”), slated to begin in May 2022. The 25,886-hectare Davidson River Project is situated in the Southwest Athabasca Uranium District of Saskatchewan and contains significant blue-sky potential to make a high-grade basement-hosted uranium discovery.

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.

Standard Uranium is a mineral resource exploration company based in Vancouver, British Columbia. Since its establishment, Standard Uranium has focused on the identification and development of prospective exploration stage uranium projects in the Athabasca Basin in Saskatchewan, Canada.

Standard Uranium’s Davidson River, in the southwest part of the Athabasca Basin, Saskatchewan, is comprised of 21 mineral claims over 25,886 hectares. Davidson River is highly prospective for basement hosted uranium deposits yet remains relatively untested by drilling despite its location along trend from recent high-grade uranium discoveries. A copy of the NI 43-101 technical report titled “Updated Technical Report on the Davidson River Property, Northwest Saskatchewan, Canada” with an effective date of March 16, 2020, that summarizes the exploration on Davidson River is available for review under Standard Uranium’s SEDAR profile (

Standard Uranium’s Sun Dog project, in the northwest part of the Athabasca Basin, Saskatchewan, is comprised of 6 mineral claims over 15,770 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.
