STALLION URANIUM ANNOUNCES THE COMPLETION OF

COYOTE PROJECT 3D GRAVITY INVERSION

Vancouver, British Columbia - July 14th, 2025 - Stallion Uranium Corp. (the “Company” or

“Stallion”) (TSX-V: STUD; OTCQB: STLNF; FSE: FE0) is pleased to report the results from

the 3D 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. (“Atha

Energy”) (TSX-V: SASK).

"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, ” stated

Matthew Schwab, CEO of Stallion Uranium Corp “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:

 3D 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 3D gravity inversion provides a powerful validation of the overall prospectivity at

Coyote," "With the inversion highlighting a series of at least five compelling targets within

an 8.5 km corridor,” commented Darren Slugoski, Vice President, Exploration at Stallion

Uranium. “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 3D gravity inversion model at Coyote reveals a well -defined low-density anomaly that is

both laterally extensive and vertically continuous, " said Kyle Patterson, P. Geo., 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, P. Geo., 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, Kyle 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 3D

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 3D 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 f ree air anomaly from the

4 of 5

dataset; 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 40m x 40m

surface XY blocks and Z blocks of 10m at the surface, increasing by 5% at depth. The total

model block depth exceeds 10km.
