Standard Uranium Announces Engagement Agreement and 2022 Winter Exploration Plans at its Sun Dog Project

Standard Uranium Ltd. ("Standard Uranium" or the "Company") (TSX-V: STND) (OTCQB: STTDF) (Frankfurt: FWB:9SU) is pleased to announce the signing of an Engagement Agreement with Ya'thi Néné Land and Resource Office ("YNLR") 1 further strengthening the Company's relationships with First Nations and northern community stakeholders. The Company is also pleased to announce plans for their winter exploration program including high resolution geophysics and diamond drilling at its 15,770-hectare, 100% wholly-owned, Sun Dog Project (the "Project"). The Project 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.

Following the signing of the Engagement Agreement with the YNLR on October 12 ^th , 2021, CEO and President, Jon Bey, and VP Exploration, Sean Hillacre, visited the Sun Dog project on October 14 ^th . During which, they followed up on occurrences of mineralization and strong radioactivity at surface with an RS-125 scintillometer, recording readings of >63,000 counts per second ("cps") at the Skye target, readings of >27,000 cps at the Java Target, and to readings of >40,000 cps at the Haven target which was recently discovered by the Company in 2020 (Figure 1).

Jon Bey, CEO and President commented: "Signing the Engagement Agreement with our First Nations and northern community representatives is a milestone event for our team at Standard Uranium and a step towards building strong relationships with local stakeholders. We have been anxiously awaiting the opportunity to explore the Sun Dog Project knowing the potential for high-grade uranium discoveries in this region. Working closely with our local stakeholders, we have the potential to bring opportunities back to this incredible region."

Sun Dog Project Planned Winter Exploration Program

The Sun Dog Project is fully permitted for the 2022 exploration program, and the Company is fully funded for it's 2022 exploration plans on the Project. The Company plans to conduct high resolution airborne magnetic and ground gravity surveys over the Skye, Haven and Java target areas on the Sun Dog Project (Figure 1) through the months of January and February 2022, leading into the inaugural drill program planned to commence in the first week of March 2022. The drill program will comprise up to 3,000 metres of diamond drilling to test high priority basement and unconformity targets for high-grade uranium mineralization at relatively shallow depths.

Sean Hillacre, VP Exploration, states: "I was extremely impressed by the abundance of structural features and uranium mineralization occurrences on the Sun Dog Project during my first visit to our target areas. The extent of the faulting and brecciation in the Athabasca sandstones and exposed basement rocks coinciding with strong radioactivity on surface at our Skye target, Java target and Haven discovery has me excited to begin our inaugural drill program and follow up on the basement "roots" of these perched mineralization systems. The strong alteration and uranium mineralization occurrences at surface bode extremely well for what is potentially contained within the down-dip extension of these major structures into the basement rocks below."

As noted in the December 8, 2020, news release, the target areas at the Sun Dog Project have many attributes that are favourable for the formation of high-grade unconformity-related uranium mineralization. The key geological factors include uranium-enriched bedrock, reactivated and graphitized structures, Athabasca Supergroup sandstone cover and favourable basement competency contrasts. The three most promising historical target areas (Skye and Java, in addition to the newly discovered Haven target) were visited in the summer of 2020 to confirm the location of historical exploration and provide context for future work. The analytical results reveal an interesting correlation between uranium and gold mineralization, whereas boron and other pathfinder elements highlight the potential for a robust alteration footprint at the Haven target area.

Ground-truth sampling in 2020 at the three main target areas: Skye, Java, and Haven, have returned outcrop and boulder grab sample results with highs of 3.58% U ₃ 0 ₈ , 1.7% U ₃ 0 ₈ and 0.7% U ₃ 0 ₈ , respectively. These high-grade uranium assay results come from widespread showings of strong radioactivity on Stewart and Johnston Islands.

New boulder grab samples were also collected from the Skye target area during the recent 2021 visit, with radiation measurements peaking at 42,000 cps (Figure 2), 27,000 cps (Figure 3) and 12,000 cps (Figure 4). These samples will be shipped to Saskatchewan Research Council in Saskatoon to provide additional U ₃ O ₈ assay data for follow up at the Skye target area.

Fall 2020 Exploration Highlights :

Skye Target Area

• 14 outcrop and boulder grab samples collected, 2 of which are greater than 0.10% U ₃ O ₈ , and range between 0.95 ppm U and 3.58% U ₃ O ₈ .
• 3 of the 14 samples returned greater than 100 ppb gold with a high of 1.02 g/t Au.

Java Target Area - JSW-1 prospect

• 14 outcrop grab samples collected, 10 of which are greater than 0.10% U ₃ O ₈ , and range between 0.07 ppm U and 1.7% U ₃ O ₈ .
• 8 of the 14 samples returned greater than 100 ppb gold with a high of 0.52 g/t Au.

Haven Discovery Area – Haven target, Walli prospect, JSW-2 prospect

• 13 outcrop grab samples collected, 5 of which are greater than 0.10% U ₃ O ₈ , and range between 136 ppm U and 0.70% U ₃ O ₈ .
• 3 of the 13 samples returned greater than 100 ppb of gold, with a high of 1.04 g/t Au.
• Proximal to the historical Walli Prospect (Figure 1), 2 of the 13 samples returned greater than 1,000 ppm of boron. These results, coupled with the anomalous uranium of 0.10 and 0.13% U ₃ O ₈ and elevated pathfinder elements such as lead, copper, cobalt, and nickel suggest the identification of a robust alteration footprint within the Athabasca sandstones.

The scientific and technical information contained in this news release has been reviewed and approved by Sean Hillacre, VP Exploration and is a "Qualified Person" as defined in NI 43-101.

Samples collected for analysis are sent to SRC Geoanalytical Laboratories (an SCC ISO/IEC 17025: 2005 Accredited Facility) in Saskatoon, SK for analysis. 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 U ₃ O ₈ 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).

Radioactivity measurements reported in this news release were measured using a handheld RS-125 Gamma-Ray Spectrometer/Scintillometer. Scintillometer readings do not constitute a qualitative or quantitative measurement of uranium concentration in the rock samples measured. Uranium mineralization referred to and pictured in samples in this news release have been identified based on mineralogical examination and scintillometer/spectrometer readings in conjunction with comparison and correlation with previously assayed samples.

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 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.

Standard Uranium's Davidson River Project, in the southwest part of the Athabasca Basin, Saskatchewan, is comprised of 21 mineral claims over 25,886 hectares. The Davidson River Project 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 that summarizes the exploration on the Davidson River Project is available for review under Standard Uranium's SEDAR profile ( www.sedar.com ).
