STALLION URANIUM ANNOUNCES THE COMPLETION OF COYOTE PROJECT 3D GRAVITY INVERSION

Stallion Uranium Corp. has released the results from the 3-D inversion of ground gravity data over the Coyote target, located within the southwestern Athabasca basin joint venture (JV) project in partnership with Atha Energy Corp.

"The inversion modelling at Coyote has delineated a laterally extensive and coherent gravity low, spatially coincident with a structurally complex corridor exhibiting attributes characteristic of fertile uranium-bearing systems within the Athabasca basin," said Matthew Schwab, chief executive officer of Stallion Uranium. "The robustness of the geophysical anomaly, in conjunction with the structural and lithological setting, provides compelling evidence supporting Coyote as a high-priority target for drill testing."

Highlights:

• 3-D gravity inversion completed and interpreted by leading geophysical experts specializing in the Athabasca basin;
• Identified multiple gravity-low anomalies along a major conductive corridor;
• A prominent, coherent gravity-low feature interpreted as a zone of alteration along an interpreted structural corridor;
• Strong correlation between the gravity anomalies and conductive breaks identified from the MobileMT survey.

The inversion results highlight a gravity-low anomaly commonly associated with significant uranium mineralization systems in the Athabasca basin. The modelled anomaly defines the low-density feature's depth extent, shape and continuity, further supporting the potential for large-scale uranium alteration at Coyote.

"The 3-D gravity inversion provides a powerful validation of the overall prospectivity at Coyote," said Darren Slugoski, vice-president, exploration, at Stallion Uranium. "The inversion highlights a series of at least five compelling targets within an 8.5 km corridor. We are well positioned to take the next steps toward discovery with a subsequent ground EM survey (currently being interpreted by Convolutions Geoscience) in addition to a focused and systematic drill program."

The inversion results visualize subsurface density variations, with the anomaly's geometry and intensity suggesting prolonged fluid movement and alteration; critical vectors toward uranium mineralization. The alignment of the gravity-low with previously defined conductive trends and interpreted structural corridors underscores a compelling geological model. The results validate the exploration strategy at Coyote and refine the prioritization of drill targets based on integrated geophysical and structural frameworks.

"The 3-D gravity inversion model at Coyote reveals a well-defined low-density anomaly that is both laterally extensive and vertically continuous," said Kyle Patterson, PGeo, principal geophysicist at Convolutions Geoscience, a leading consulting firm specializing in advanced geophysical modelling and geologic integration. "This type of geophysical signature is commonly associated with deep-seated structural zones and extensive hydrothermal alteration; both key indicators in targeting basement-hosted uranium deposits in the Athabasca basin. The spatial correlation with interpreted MobileMT conductors, observed alteration patterns and interpreted shear zones further support the interpretation that the Coyote project hosts the ideal geological pathfinders for a significant uranium system."

About Kyle Patterson

Kyle Patterson, PGeo, is the chief geophysicist and founder of Convolutions Geoscience, a geophysical consulting firm specializing in advanced modelling and interpretation techniques for mineral exploration. With over 15 years of experience in the industry and a focus on high-resolution geoscientific data integration in the Athabasca basin, Mr. Patterson has worked extensively with uranium explorers to define and refine targets using gravity, magnetics, and EM inversion modelling. His expertise is in interpreting complex structural and alteration systems, bridging geophysics with geological understanding to drive discovery-focused exploration.

Gravity data inversion

Convolutions Geoscience inverted the ground gravity data, utilizing industry-standard 3-D inversion techniques to estimate subsurface density variations from the processed gravity data. The objective was to assist in delineating alteration zones of interest for uranium exploration.

Convolutions Geoscience carried out a 3-D inversion of the gravity data to create a voxel product of subsurface density anomalies using the industry-standard Fullagar vertical prism magnetic and gravity (VPmg) codes. The inputs into the inversion were the free air anomaly from the data set; lake bathymetry data for water depth; digital terrain model (DTM) for the project area, in addition to NASA Shuttle Radar Topography Mission (SRTM) data for surrounding areas; and density constraints for sandstone cover rocks above the unconformity as well as basement rocks below the unconformity. Convolutions created a VPmg gravity inversion using 40-metre-by-40-metre surface XY blocks and Z blocks of 10 m at the surface, increasing by 5 per cent at depth. The total model block depth exceeds 10 kilometres.
