Standard Uranium regains full ownership of Sun Dog project
Standard Uranium Ltd (TSX-V:STND, OTCQB:STTDF) announced that it has regained full, unencumbered ownership of the Sun Dog project following the conclusion of its property option agreement with Aero Energy.
The arma’s-length agreement, signed in October 2023, had allowed Aero to earn up to a 100% interest in the project.
The company said it is preparing plans to advance exploration at Sun Dog, building on drilling and geophysical work conducted in 2024 and 2025.
The Sun Dog Project covers 48,443 acres across nine mineral claims about 15 km southeast of Uranium City on the northern edge of the Athabasca Basin.
The property hosts the historical Gunnar Uranium Mine, which produced approximately 18 million pounds of U₃O₈ between 1953 and 1981.
“Sun Dog is a fantastic project that continues to garner a great deal of interest from multiple companies,” Standard Uranium CEO Jon Bey said in a statement.
“We are excited to have the Sun Dog project returned to our portfolio and confident that we will have another joint venture partner funding further exploration in the next year.
Bey also wished the Aero Energy team future success as they focus on their other uranium projects in Canada and the US. “They were a great partner to work with the past two years,” he said.
According to Standard Uranium, historic and recent work at Sun Dog has returned high-grade uranium assays from 0.01% to 17.4% U₃O₈, with mineralization identified both below and above the Athabasca Basin unconformity. Drilling has intersected graphitic structural zones and hydrothermal alteration linked to uranium.
Exploration programs since 2020 have included prospecting, mapping, geophysical surveys, and drilling, leading to the Haven discovery and additional radioactive zones and mineralized boulders identified in 2022 and 2024.
Geophysical work from 2022 to 2025, including gravity, magnetic, and airborne EM surveys, has outlined conductive graphitic units and density-low anomalies interpreted as potential alteration or structural targets.
Standard Uranium has completed 4,062 metres of drilling across 21 holes, intersecting alteration zones, graphitic shears, quartz-hematite breccias, and anomalous uranium. The company said these results will guide prioritization of future drill targets.
