STALLION COMPLETES GROUND GRAVITY, IDENTIFIES THREE
NEW PRIORITY TARGET AREAS AT STONE ISLAND
Vancouver, British Columbia - September 3, 2026 - Stallion Uranium Corp. (the “Company”
or “Stallion”) (TSX-V: STUD; OTCQB: STLNF; FSE: B76) is pleased to announce results from
its 2026 ground gravity survey at the Stone Island target, located on claims owned 100% by
Stallion within the Moonlite Project in the southwestern Athabasca Basin, Saskatchewan.
Integration of the gravity results with the Company’s 2026 VTEM Plus survey has identified
three new priority target areas - A, B and C - expanding Stallion’s exploration pipeline of high-
priority targets beyond the Coyote target.
“Stone Island is developing into an important second priority area within the Moonlite
Project,” said Matthew Schwab, President and Chief Executive Officer of Stallion Uranium.
“The combination of gravity and VTEM data has identified three distinct areas f or follow-
up, led by Target Area A where multiple conductors coincide with the strongest gravity
low. Advancing targets outside Coyote strengthens our project pipeline and gives us
multiple opportunities for future discovery.”
Target Area A is the strongest integrated target and contains multiple VTEM conductor picks
within the principal gravity low. Target Areas B and C provide additional follow-up opportunities
where conductive trends are spatially associated with distinct gravity gradients. In Athabasca
Basin exploration, these combined responses are important because gravity lows or gradients
can reflect structural disruption, alteration, lithological contrasts or combinations of these
features associated with prospective uranium-bearing systems.
Highlights:
Three new priority target areas identified at Stone Island through integration of 2026
gravity and VTEM Plus data
Target Area A: primary target: Multiple VTEM conductor picks coincide with the
strongest residual gravity low, defining the most compelling integrated geophysical
response at Stone Island
Target Area B: northern extension: VTEM responses continue north of Target Area A
along a distinct gravity gradient
Target Area C: separate southwest target: A discrete conductor is associated with a
localized gravity gradient, providing an independent follow-up target
Target refinement underway: Gravity, VTEM, magnetic and structural datasets are
being integrated to rank conductor segments and define potential drill targets
"The key result is the geometry of the combined responses,” commented Darren Slugoski,
P.Geo., Vice President Exploration. “Target Area A shows the strongest overlap between
a north-trending conductor and the principal gravity low. Areas B and C provide additional,
distinct targets that will now be advanced through detailed conductor modelling and
structural interpretation."

Stone Island Target Development:
The 2026 ground gravity survey comprised 519 stations and was completed to refine targets
identified by Stallion’s approximately 690 line- kilometre VTEM Plus survey over Stone Island.
The integrated interpretation has identified three priority areas where conductive trends coincide
with gravity lows or gradients.
Target Area A is the highest -priority target, where multiple VTEM responses overlap the
strongest portion of the principal gravity low. Target Area B extends north along the same
general conductor trend near a separate gravity gradient. Target Area C is a distinct southwest
target where a conductive trend follows the margin of a localized gravity feature.
Gravity lows are not direct indicators of uranium mineralization, but when integrated with
conductive trends and structural information they can help identify areas of alteration, structural
disruption or lithological contrast that warrant further evaluation.

Next Steps:
Complete detailed conductor modelling and resistivity-depth interpretation for priority
VTEM responses
Integrate gravity and conductor geometry with magnetic breaks, interpreted faults and
regional basement trends
Rank the three target areas and evaluate the highest-priority zones for additional ground
geophysics and future drill testing, subject to final interpretation, permitting and program
approval
About the Ground Gravity Survey and 3D Inversion:
MWH Geo-Surveys (Canada) Ltd. completed 519 unique ground gravity stations over Stone
Island, together with repeat readings for quality control. The survey achieved a typical mean
data accuracy of approximately 0.02 mGal.
Convolutions Geoscience Corporation subsequently completed a physical-property-constrained
3D inversion of the Stone Island gravity data. The inversion incorporated the gravity
measurements, terrain information, and available geological, drillhole and petrophysical density
data to produce a 3D model of the subsurface density distribution.
Additional News:
The Company also announces that it has terminated its investor relations services agreement
with Straight Edge Marketing Inc., d/b/a InvestorHyve (to update the disclosure in its May 27/26
and July 7/26 news releases). As a result of the termination, InvestorHyve will no longer provide
investor engagement or related services to the Company.
