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.
