Pushing the Limits of the Basin’s Frontier
Overview
The 100% owned Borderline Project consists of one claim with a total area of 5,437 hectares situated along the Saskatchewan – Alberta Border in the southwestern Athabasca Basin. A VTEMTM plus was completed on the property in winter 2023 to cover the entirety of the property.
The Beatty River Fault is located 7-km south of the property and is believed to be the driver of uranium-rich fluids which can be trapped and deposited along the structures on the project.
Exploration Targets
Borderline Target
The Borderline Target, part of Stallion Uranium’s Borderline Project, represents an underexplored but structurally favorable area on the western margin of the Athabasca Basin. A 2023 VTEM™ Plus survey totaling 336 line-kilometres was completed across the property, providing modern coverage over a zone that has seen limited historical drilling despite encouraging geophysical and structural features.
The target lies proximal to major regional structures, including the Beatty River Fault, a deep-seated, long-lived basement feature that has been associated with uranium mineralization elsewhere in the basin. Additional structural complexity is evident along the eastern edge of the claim block, where magnetic data suggests intense deformation and faulting — key criteria for fluid migration and trap formation.
Geological mapping by Card (2006) identifies a significant lithological contact between granitoid gneiss and high-grade metasedimentary rocks in this area. Such lithologic contrasts, particularly when coinciding with structural breaks, are known to play a critical role in focusing uranium-bearing fluids. Multiple conductor trends have been previously identified over the property, including responses from the 2004 Avera MEGATEM survey and the 2016 ZTEM survey conducted by NexGen Energy.
With a favorable structural setting, recognized conductor systems, and confirmed basement geology, the Borderline Target represents a compelling candidate for future follow-up through high-resolution ground geophysics and drilling.
Exploration Roadmap
Stallion Uranium’s exploration strategy at the Borderline Target follows a disciplined, data-driven approach tailored to the geological complexity and depth of the target area. With a foundation of high-quality historical and modern geophysical datasets, the roadmap is designed to de-risk and advance the target toward discovery efficiently.
- Compile and reinterpret all available datasets, including the 2023 VTEM™ Plus, 2016 ZTEM, and 2004 MEGATEM surveys.
- Complete and AFMAG survey to map full extent of the structures.
- Map structural corridors, particularly those associated with the Beatty River Fault and magnetically inferred lineaments.
- Deploy targeted ground EM surveys (such as Fixed-Loop or Stepwise Moving Loop EM) over high-priority conductors.
- Complete gravity surveying to assist in identifying basement alteration zones associated with mineralization.
- Identify structural intersections and potential fluid trap zones where uranium may have concentrated
- Drill Program - Design initial drill holes to test the most compelling conductor/structure intersections at depth. Focus on areas with overlapping conductor responses, favorable structure, and lithological contacts.
