STALLION URANIUM REFINES COYOTE TARGET WITH HIGHLY
CONDUCTIVE ANOMALIES FROM GROUND EM SURVEY,
MOBILIZES STONE ISLAND VTEM SURVEY
Vancouver, British Columbia - January 12, 2026 - Stallion Uranium Corp. (the “Company”
or “Stallion”) (TSX-V: STUD ; OTCQB: STLNF ; FSE: B76) is pleased to announce the
completion of a ground- based Step -Wise Moving Loop (“SWML”) Time- Domain
Electromagnetic (TDEM) survey at the Coyote Target on its Moonlite Property, located in the
Athabasca Basin of northern Saskatchewan. The survey was completed by Abitibi Geophysics.
The Company also reports that is has mobilized an airborne VTEM survey over its Stone Island
Target, also on the Moonlite Property in the Athabasca Basin.
“The SWML survey has successfully defined and modelled multiple high- quality
conductors across the Coyote Target,” said Darren Slugoski, VP Exploration of Stallion
Uranium. “With nine conductors identified; seven of which exhibit strong conductance
levels; the modelling completed by Abitibi provides the resolution required to precisely
position drill holes and optimize drill orientations. This work materially improves our
confidence in drill targeting and directly supports a focused and technically driven w inter
drill program.”
Matthew Schwab , CEO of Stallion Uranium, added, “This survey represents a key
technical milestone at Moonlite. The identification of multiple strong, structurally complex
conductors within a broader gravity-low anomaly reinforces our confidence in the Coyote
Target and positions Stallion well as we advance toward drilling commencement.”
Highlights:
Ground SWML (Step-Wise Moving Loop) TDEM survey completed at the Coyote Target
on the Moonlite Property, Athabasca Basin, Saskatchewan
Survey extends the existing EM grid, significantly improving coverage and resolution
across the broader Coyote Target area
Nine discrete electromagnetic conductors identified, including six strong conductors
(>10 Siemens) considered significant in a basement-hosted uranium exploration context
Significant lateral and vertical offsets observed within multiple conductors, interpreted to
reflect faulting and structural disruption
Conductor offsets and terminations are interpreted to indicate structural complexity and
potential trap sites, favorable for uranium deposition
The most significant observation is the complexity of the conductor network, which
occurs within a broader gravity-low anomaly, suggesting a zone of enhanced structural
disruption
Electromagnetic modelling completed by Abitibi Geophysics provides improved
constraint on conductor geometry, depth, and orientation
Integration of SWML, gravity, magnetic, and geological datasets will allow for precise
drill collar placement and optimized drill orientations

Survey Overview:
Preliminary interpretation of the SWML-TDEM data has identified nine discrete electromagnetic
conductors within the expanded survey area at the Coyote Target. Of these, six conductors
exhibit strong conductance values exceeding 10 Siemens, which are considered significant in
the context of basement-hosted uranium exploration in the Athabasca Basin.
The identified conductors are interpreted and modelled as:
Coyote_15S, Coyote_14S, Coyote_12.5S, Coyote_12S, Coyote_11S, Coyote_10.5S
Additional moderate conductors defined by the survey include Coyote_7.5S, Coyote_7S, and
Coyote_5S.

These conductors occur within the broader Coyote Target area and are interpreted to be
structurally controlled. Their geometry, continuity, and depth extent are currently being
integrated with existing geological and geophysical datasets.

Results:
Inversion modelling of the gravity data identified multiple density low zones proximal to the
unconformity, most notably a large, circular density low located in the southeastern quadrant of
the survey grid. Maxwell plate modelling of the ground EM data delineated high- conductivity
plates (10- 15 S) that exhibit strong spatial correlation with these density lows. This
correspondence is interpreted to indicate hydrothermal alteration developed within a graphitic
shear zone, consistent with structurally controlled basement-hosted uranium systems.
To further constrain the geometry and continuity of the conductive features, a joint inversion
incorporating Ground TEM and larger-scale MobileMT data was undertaken by Computational
Geosciences Inc. This approach was critical in refining conductor trends, as it is not limited by
the thin-plate assumption inherent in the Maxwell plate modelling workflow. The joint inversion
augments the plate modelling by allowing for curvilinear conductor geometries and improved

definition of strike extents. Notably, a break in the main conductor trend is observed coincident
with a density high in the gravity model, indicating a likely structural control on conductor
development and continuity.
SWML-TDEM Survey:
Abitibi Geophysics completed the SWML- TDEM survey over a single 5.8 km -long line using
nine overlapping transmitter loops (each 400 m x 600 m), recording high- resolution
electromagnetic responses at regularly spaced receiver stations along the profile. Thi s survey
was conducted using Abitibi Geophysics’ proprietary ARMIT -TDEM system, which captures
both B-field and dB/dt responses across three components simultaneously. These two data
types are sensitive to different conductivity ranges and, when combined, enhance the detection
and resolution of subsurface conductors.
The use of stepwise overlapping loops improves resolution compared to fixed-loop systems and
is particularly well-suited for identifying discrete conductors in the complex basement geology
of the Athabasca Basin. The data were collected using 10 Hz base fr equency, with robust
stacking, QA/QC protocols, and real-time data validation to ensure high-quality results.
About the Plate Modeling:
Once field data were collected, advanced 3D modeling was conducted using EMIT Maxwell
software to convert raw EM data into interpretable geological features. The modeling process
used the Leroi algorithm to simulate conductive plates within a layered- earth model; a critical
feature for Athabasca-style settings where strong resistivity contrasts exist above and below the
unconformity.
Modeling began with verification of survey geometry and the removal of noisy or suspect
readings. Conductor plates were then inserted, oriented, and refined to match the observed EM
response across multiple components. The final plate models were evaluated for geological
plausibility, structural coherence, and data fit. The resulting models were exported and
integrated with gravity, historical, and structural datasets to prioritize drill targets with the highest
discovery potential.
VTEM™ Plus Survey Mobilization - Stone Island Target:
Stallion Uranium has commenced mobilization of a helicopter -borne VTEM™ Plus (Versatile
Time Domain Electromagnetic) geophysical survey over the Stone Island Target at its Moonlite
Project in the eastern Athabasca Basin, Saskatchewan. Mobilization of the survey began on
January 6, 2026, marking the first geophysical survey conducted by the Company on the
Moonlite Project since the claims were staked.
The VTEM ™ Plus survey is designed to identify electromagnetic conductors and structural
features beneath Athabasca sandstone cover that may be associated with uranium
mineralization. The resulting targets are expected to be relatively shallow and amenable to
efficient follow-up exploration. The survey will also provide detailed magnetic data to aid in
mapping lithological boundaries and structural trends across the Stone Island area.

Results from the VTEM™ Plus survey will establish a foundational geophysical dataset for the
Stone Island Target and will be integrated with geological interpretations to refine target
generation and guide future exploration programs at the Moonlite Project.
