Standard Uranium Ltd. announced that the Phase II summer 2021 diamond drill program has officially begun at the Company’s 25,886 hectare Davidson River Project, 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. 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. The Phase II winter drill campaign on the Project was conducted between February 8, 2021 and March 29, 2021. 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. These conductive trends are associated with graphitic-sulphidic structures in basement rocks, which are commonly associated with uranium mineralization systems.
