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.
