Standard Uranium Ltd. (“Standard Uranium” or the “Company”) (TSX-V: STND) (OTCQB:STTDF) (Frankfurt: FWB:9SU) is pleased to announce that the Phase II summer 2021 diamond drill program has officially begun at the Company’s flagship 25,886 hectare Davidson River Project, (the “Project” or “Davidson River”) located in the Southwest Athabasca Uranium District of Saskatchewan 25 km to 30 km to the west of Fission Uranium’s Triple R and NexGen’s Arrow deposits. The Company is also happy to announce a summary of results from the Phase II winter 2021 diamond drilling program from the same Project.

Davidson River Phase II Summer Drilling Underway

The Davidson River Phase II summer drill campaign officially started with hole DR-21-020 breaking ground on May 29, 2021. This first drill hole of the summer 2021 drill program is a 650 m step-out to the northwest along strike of the Saint trend from hole DR-20-018, which intersected graphitic basement structures and localized hydrothermal alteration. The first portion of the summer program will focus on testing new high-priority targets along the Saint and Bronco trends, as well as follow-up holes along the Warrior trend. The Company will utilize the overburden drilling expertise of Geotech Drilling Services Ltd. (“Geotech”) in areas of thicker glacial till deposits to optimize drilling efficiency and budget. The planned 10,000 m program will comprise aggressive step-outs along strike of all four major conductive corridors on the Project, centering on high-priority geophysical, structural, and geochemical target areas.

Davidson River Phase II winter results summary

The Phase II winter drill campaign on the Project was conducted between February 8, 2021 and March 29, 2021. Full details of the news release can be found on our website . The winter program focused on following up on Phase I drill results along the Warrior trend and broke ground on the Saint trend for the first time. Seven (7) drill holes comprising 3,020 m of diamond drill core were completed, with six (6) holes drilled along strike of the Warrior trend and the one (1) hole on the Saint trend (see Table 1 below). These conductive trends are associated with graphitic-sulphidic structures in basement rocks, which are commonly associated with uranium mineralization systems.

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

Rock types and structure

  • Significant deep structural zones were intersected along both the Warrior and Saint trends;
  • Evidence of brittle reactivation associated with local hydrothermal clay and chlorite alteration was observed in structural zones within the hanging wall (west side) of the Warrior corridor;
  • Moderate to strong concentrations of graphite and sulphide minerals are present within stacked high strain zones and fault strand linkages along both trends; and
  • Strongly silicified phyllonite (shear) structure at greater than 400 m depth in hole DR-21-018 along the Saint trend, bound by graphitic high strain zones.

Geochemistry Highlights

  • Several zones of anomalous boron (1,960 ppm B from 268.1 to 268.2 m in DR-21-016; 1,090 ppm B from 181.5 to 182.0 m in DR-21-021) within the hanging wall of the Warrior trend exhibiting a strong spatial correlation to reactivated basement structures;
  • Anomalous uranium (8.5x background values, up to 14.6 ppm U over 3.75 m from 167.15 to 170.9 m) and pathfinder elements (e.g., B, Ni, Co, Mo, V, REE) within a Devonian sandstone composite sample in hole DR-21-015 along the Warrior trend; and
  • Localized uranium anomalism (up to 61.0 ppm U from 403.5 to 404.0 m) proximal to graphitic basement structure in hole DR-21-018 along the Saint trend, associated with anomalous Pb isotope ratios.

Phase II winter 2021 geochemical results have been compiled and incorporated into the Davidson River geological model and will be used in conjunction with Phase I 2020 data to further aid in drill target vectoring along the Warrior trend for the upcoming Phase II summer 2021 drill program. In addition, the elevated uranium returned from the first drill hole along the Saint trend bodes well for continued exploration drilling along the trend this summer. The Company also plans to begin testing the other main conductive corridors on the Project, the Bronco and Thunderbird trends.

Areas of anomalous Pb ratios are highlighted by dashed yellow ellipses. Areas of anomalous boron assays in the hanging wall of the Warrior corridor are highlighted by dashed orange ellipses. Pb isotope ratios were calculated from Pb isotope ppm total digestion assays.

Sean Hillacre, Vice President of Exploration commented: “It is great to see overlapping structure and geochemical pathfinder elements along the Warrior trend and uranium anomalism in the basement on our first hole drilled along the Saint trend. As we continue to collect data from our drill programs, this will help us vector into a high-grade uranium discovery. The trends and correlations we are seeing on the Project have been integrated into our summer 2021 drill targeting, and we are very excited to have resumed drilling.”

Drill core samples from the Phase II winter 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. 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.
