Standard Uranium Ltd. announced analytical highlights from the winter 2023 drill program at its 19,603-hectare Sun Dog Project . 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.Ten diamond drill holes comprising 1,227.1 m were completed in March 2023 at the Johnston Bay, Java, Haven, Walli, and Stewart Island target areas. The program was designed to follow up on the results of the 2022 drill program, test historical high-grade uranium mineralization, and test for the down-dip extension of mineralized structures mapped at surface. The results of the program highlight the potential for the property to host significant unconformity- related and basement-hosted uranium mineralization. Sun Dog contains several priority targets to follow up on previous drill hole intersects of uranium mineralization and basement-rooted structures that warrant further exploration. These factors, along with the presence of numerous radioactive mineral occurrences in both basement rocks and the overlying Athabasca sandstone, indicate excellent potential for economic uranium mineralization within the Sun Dog Project area. Additionally, the discovery of an extensive dravite-clay-iron oxide alteration system on Johnston Island which corresponds with elevated radioactivity, further supports the potential for shallow high-grade uranium mineralization. Drill hole SD-23-012 returned 2.31 ppm uranium in silicified Athabasca sandstone (MFd) within a dm-scale quartz-hematite breccia from 9.25 to 9.40 m. Elevated uranium was also intersected in drill hole SD-23-006, returning 1.32 ppm uranium in Athabasca sandstone (MFb) with
hydrothermal hematite healed fractures, local druzy quartz veins, and sooty pyrite fractures. Uranium concentrations above 1.0 ppm are considered anomalous in Athabasca sandstone. Drill hole SD-23-013 returned the highest uranium value of 0.042 wt.% U3O8 over 0.5 m (360 ppm U, partial digest) in an oxidized fault breccia hosting clay-dravite alteration. Within the same structure, 0.021 wt.% U3O8 over 0.5 m (136 ppm U, partial digest), and 0.005 wt.% U3O8 over 1.0 m (35.2 ppm and 33.2 ppm U, partial digest) was intersected. In the sandstone and basement, elevated uranium exceeds thorium values by a factor of 2 in multiple intervals, supporting hydrothermal uranium emplacement processes.SD-23-013; Haven discovery (Figure 3): o Down-dip follow up of fault-controlled off-scale** surface mineralization at the Haven discovery. Visible uraninite at surface. 0.042 wt.% U3O8 from 79.0 to 79.5 m, as well as anomalous nickel (65 ppm), arsenic (62 ppm), boron (110 ppm), lead (15 ppm), and molybdenum (1 ppm). 0.021 wt.% U3O8 from 79.5 to 80.0 m, as well as an anomalous 206Pb/204Pb lead isotope ratio (0.13), anomalous nickel (45 ppm), boron (158 ppm), and arsenic (32 ppm). 0.005 wt.% U3O8 from 82.5 to 83.5 m, in addition to anomalous boron (153 ppm). Weak to locally strong dravite alteration throughout, with a dravite and kaolinite peak in a deformation zone within semi-pelitic gneiss at 122 m. SD-23-012; Walli showing: Down-dip follow up of surface mineralization up to 45,000 cps west along strike of hole SD-23-011. Anomalous lithium (132 ppm), nickel (15 ppm), boron (113 ppm), and vanadium (5 ppm) in silicified upper MFd sandstone from 3.0 to 5.0 m. Anomalous uranium (2.31 ppm), vanadium (4 ppm), and nickel (4 ppm) from 5.0 to 9.5 m, associated with a quartz-hematite breccia from 9.25 to 9.40 m. Anomalous boron (2,560 ppm) and vanadium (54 ppm) in sheared pelitic gneiss from 60 to 60.1 m. Strong fracture-hosted dravite (83.3%) directly below the unconformity at 11 m, with additional concentrations up to 30% downhole associated with fracture zones.
