STALLION URANIUM ANNOUNCES COMPLETION OF GROUND

GRAVITY SURVEY OVER COYOTE TARGET

Vancouver, British Columbia - April 30th, 2025 - Stallion Uranium Corp. (the “Company” or

“Stallion”) (TSX-V: STUD; OTCQB: STLNF; FSE: FE0 is pleased to announce the successful

completion of a ground gravity survey over its Coyote Target, located within the Southwestern

Athabasca Basin Joint Venture ( “JV”) Project in partnership with Atha Energy Corp. (“Atha

Energy”) (TSX-V: SASK). The survey marks a critical step in advancing the exploration efforts

in this highly prospective uranium region.

Highlights:

 Significant gravity low anomaly identified, closely resembling the geophysical signature of

the Arrow Deposit and other significant discoveries in the Athabasca Basin.

 Structural and geophysical features align with those of NexGen Energy’s Arrow Deposit,

reinforcing the potential for Tier-1 uranium mineralization.

 Gravity anomaly located in a structurally complex corridor, characterized by intersecting

conductors and breaks; prime settings for uranium deposition.

 Ongoing 3D Inversion of Ground Gravity to identify depth and shape of the gravity

anomaly.

"The results of our ground gravity survey at the Coyote Target mark a significant milestone in

our exploration efforts within the Athabasca Basin. ” said Matthew Schwab CEO of Stallion

Uranium Corp. “The identification of a substantial gravity low anomaly mirroring the

characteristics of world -class uranium deposits reinforces our confidence in Coyote’s

potential. This advancement strengthens our commitment to pursuing exploration in this highly

prospective region, and we are eager to take the next steps in unlocking the value of this

target through focused drill ing. Stallion remains dedicated to executing a systematic and

science-driven approach as we continue to build shareholder value through discovery."

The survey encompassed a total area of 2,623 hectares, with 2,738 gravity stations strategically

placed to detect subsurface variations in density that may indicate uranium alteration. The

results revealed a substantial gravity low anomaly, a hallmark feature associated with large-

scale uranium deposits, such as NexGen Energy’s Arrow Deposit. The Arrow Deposit, one of

the most significant uranium discoveries in the Athabasca Basin, shares multiple geological and

geophysical similarities with the Coyote Target, strengthening confidence in the potential for a

high-grade uranium discovery.

“Our ground gravity survey has identified a highly compelling target that exhibits striking

similarities to the world -class Arrow Deposit,” said Darren Slugoski, Vice President,

Exploration at Stallion Uranium. “The anomaly’s location is particularly compelling, as it

coincides with structural complexities and breaks in conductors, and geological features that

are strikingly similar to those associated with the Arrow Deposit. The convergence of multiple

overlapping anomalies solidifies Coyote as a Tier 1 ex ploration target, warranting further

advancement through targeted drilling.”

Survey Area:

The Coyote Target is strategically positioned 58 kilometers northeast of NexGen Energy’s Arrow

Deposit, which hosts an estimated 256.7 million pounds of U ₃O₈ at an average grade of 3.1%

U₃O₈ (2021, NI 43-101 Technical Report). The gravity anomaly identified at Coyote aligns with

key geological characteristics of Arrow, including structural breaks, intersecting conductive

corridors, and large-scale alteration zones. This strong resemblance suggests that Coyote has

the potential to host a world- class uranium deposit similar in scale and grade to Arrow. Given

the compelling nature of these findings, Coyote is now a top-tier priority for Stallion’s upcoming

exploration programs.

About the Ground Gravity Survey:

Beginning February 5 and concluding February 21, 2025, MWH Geo-Surveys (Canada) Ltd.

carried out a gravity survey at the Coyote Target in Saskatchewan. The survey utilized a

customized L&R digital, electronic feedback gravity meter, operated via proprietary controller

software. These advanced gravity meters, incorporating electronic levels and electronic nulling,

ensure fast, accurate, and reliable readings, particularly in cold-weather conditions.

At each gravity station, GControl software, developed by MWH Geo-Surveys, recorded gravity

samples at 1-second intervals. The resultant average of these readings was used as the final

gravity measurement, significantly reducing high-frequency noise caused by wind and ground

motion. Additionally, GControl calculated real -time, location- specific tidal corrections during

data collection, enhancing the accuracy and reliability of the survey results.

With a typical mean data accuracy of 0.02 mgals, MWH Geo- Surveys continues to set the

standard for high-resolution gravity surveys, delivering reliable results for resource exploration

and geophysical studies.
