Standard Uranium holds a 100%-interest in the 17,309-hectare Sun Dog project along the northwestern edge of the Athabasca Basin (Figure 1). The Sun Dog project is comprised of 6 contiguous mineral claims (Figure 2) located near Uranium City at the south end of the prolific Beaverlodge uranium district where uranium was mined between 1953 and 1982. Unlike the previously mined lower-grade Beaverlodge type deposits from this area, Standard’s exploration strategy at Sun Dog is targeting high-grade unconformity-related deposits that are typical of the Athabasca Basin, which would be a remarkable discovery in Canada’s original uranium mining district.
The three most promising historical target areas (Skye, Java, and Haven; Figure 3) were visited in Fall 2020 to confirm the location of historical exploration results and provide context for current work. Fall 2020 sampling efforts at the Skye, Java, and Haven target areas identified several zones of off-scale and visible uranium mineralization at surface (Photo 1 and Photo 2), and returned uranium assay results up to 3.58% U3O8, 1.7% U3O8, and 0.7% U3O8, respectively. Additionally, the analytical results reveal a correlation between uranium and gold mineralization, while boron and other pathfinder elements highlight the potential for a robust alteration footprint associated with uranium mineralization.
The Company completed four drill holes for 1,242 metres of diamond drilling in winter 2022, during an inaugural reconnaissance-scale drill program.
Highlights from the project include:
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.
