Stallion Uranium Highlights Prospectivity of Intersected Conductive
Structure at Appaloosa Target
Vancouver, British Columbia, June 12, 2024 – Stallion Uranium Corp. (the "Company" or "Stallion") (TSX-V: STUD;
OTCQB: STLNF; FSE: FE 0) is pleased to announce the significant advancements and interpretations from the
maiden drill program completed on the Appaloosa target, located on its 100% owned Coffer Project. Appaloosa
is an advanced exploration target that is part of its broader portfolio of high -potential uranium projects held by
Stallion in the prolific southwestern Athabasca Basin, Saskatchewan where the company holds the largest land
package.
The Appaloosa target is located on the northern end of Stallion’s 100% owned Coffer project and is only 13km
west of the Shea Creek deposit, home to over 95m lbs. of uranium 1 (Figure 2). Hole CF24-003 intersected the
targeted graphitic conductor roughly 150m below the unconformity providing the company with the location and
overall geometry of the structure. Given the depth of the intersection below the unconformity, the hole would
have undershot intersecting potential unconformity mineralization as seen in Figure 1. The length of the graphitic
conductor intersection was over 94m, showing considerable scale with the potential to host a large size deposit.
The intersection also presented radioactivity levels above background, as well as significant alteration, consisting
of intense white to pale green clay-chlorite alteration and yellow U-silicates that were observed at the Shea Creek
Deposits. Stallion’s technical team have been interpreting the geological data and given the data have clear
analogs to the Shea Creek deposit area to help understand future targeting and the targets potential. The next
drill holes will target the intersection of the graphitic structure and the unconformity to test for an unconformity
style deposit similar to UEC/Orano’s Shea Creek Deposit.
“Stallion’s maiden drill program was big step towards a discovery hole for the company. We now know the location
of the targeted structure, we know the structure is fertile from anomalous radioactivity in all 3 drill holes, we know
the structure is large enough to host a significant deposit, and we know where to target next,” said Stallion CEO,
Drew Zimmerman.

* The Company considers greater than 80 cps (on the RS-230 scintillometer) to be above background from the background radioactivity levels of 30-60 cps.
*Background gamma readings through non-elevated zones typically range from 30-60 cps on the RS-230 Handheld Scintillometer.
*Hole CF24-003 was probed to a deep of 850 meters due to the limits of the winch.
Darren Slugoski, VP Exploration Canada, said, “Having intersected strong alteration and structure in CF24-003 that
are comparable to the Shea Creek deposit model gives use a strong indication that Stallion is in the appro priate
area for uranium mineralization. Given the data from the maiden drill program the target area shows significant
potential for discovery in a follow up drill program. The Appaloos a target has not been tested at the intersection
of the unconformity and graphitic structure, which will be top priority in the next phase on exploration.”
Appaloosa Target Summary
The Appaloosa target was first uncovered through the regional survey work completed by Stallion. When compiled
with available historical data the target area had promising indicators known to host substantial uranium
mineralization. The company then completed a ground TDEM SQUID (Superconducting Quantum Interference
Device) survey developed specifically for resolving conductors at extremely low-frequencies. The comprehensive
data was able to identify key prospective zones within the target area, supporting the potential for economically
viable uranium deposits that should be drill tested.

Stallion’s maiden drill program commenced on March 6, 2024 and was completed by CYR Drilling International
drilling a total of 2,798.2m over 3 holes. Each hole was a 700m step out from the prior hole covering over 1.4 km
of the conductive trend. The remaining 4 km of strike of the conductor remains untested and provides multiple
additional targets for exploration.
Highlights of each Drill Hole
• CF24-001 was drilled targeting a conductive anomaly along the eastern edge of a gravity low anomaly.
The drill hole was successful in encountering anomalous radioactivity in the Athabasca Sandstone just
above the unconformity as well as a second interval of anomal ous radioactivity located 1.6 m into the
basement. Anomalous radioactivity was encountered in the Athabasca Sandstone with a radioactive peak
of 1,540 CPS in a 4.2 m interval that averaged 358 cps, including 0.3 m at 1,322 cps. This hole was
successful in identifying the trends of the geology and the true depth of the unconformity. This data was
used to adjust target parameters on CF24-002 and 003.
• CF24-002 is located 700 metres west of CF24 -001 and is targeting an EM conductor located within a
gravity low. CF24-002 was a large step-out that was successful in following up radioactivity intersected in
CF24-001. Anomalous radioactivity was encountered in the Athabasca Sandstone at the unconformity
with radioactivity of 333 cps over 3.4 m including 644 cps over 0.3 with a radioactive peak of 771 cps.
Radioactivity is associated with bleaching, hematite and stockwork fractures
• CF24-003 is located 700 m west along strike from CF24-002, and 1.4km west of CF24-001 and targeted an
EM conductor that was located within a coincident gravity low. After the final adjustments were made to
the location of CF24 -003, a deep-rooted conductive structure, spanning 94.7 meters in down -hole
thickness, was encountered. This structure is associated with significant strong clay and chlorite alteration
and radioactivity that is above background.
Future Drill Program
Given the strong results a future drilling program will be required to further test for uranium mineralization at the
Appaloosa target zone. Based on the significant alteration in tersected, a future drill program will have the
objective of testing for an unconformity uranium deposit up-dip from drill hole CF24-003 as well as test the extent
of the alteration along strike to the East and West. Radioactivity detected in CF24-001 will be followed up with
newly re-targeted drill holes, informed by data from CF24-003, as the modeled conductor was not intersected.
Pending Assays
The company has sent a total of 282 samples from the 3 holes to be assayed at the SRC Geoanalytical Laboratories
in Saskatoon, Saskatchewan. The company is still awaiting the results of the assays and will release assays when
available.

Gamma Logging and Geochemical Assaying
All core radioactivity was measured using a RS-230 BGO Super-SPEC Handheld Gamma-Ray Spectrometer. Down
hole probing radiometric surveying was conducted with a Mount Sopris 2PGA-1000 downhole total gamma probe
with a maximum depth of investigation of 850 meters . The Company considers greater than 300 cps (on the
borehole probe) to be anomalous radioactivity. Radioactivity greater than 80 cps using the RS -230 handheld
scintillometer is considered to be “Above Background”. The background radioactivity levels in the Appaloosa
Target area are considered 30-60 cps.
All drill core samples from the 2024 program will be shipped to the Saskatchewan Research Council Geoanalytical
Laboratories ("SRC") in Saskatoon, Saskatchewan, an ISO/IEC 17025/2005 and Standards Council of Canada
32583566v1
certified analytical laboratory. Stallion Uranium requests multi-element analysis by ICP-MS and ICP-OES using total
(HF:NHO3:HClO4) and partial digestion (HNO3:HCl), boron by fusion. One half of the split core samples are
retained and the other half cores are sent to the SRC for analyses. Blanks, standard reference materials, and
repeats are inserted into the sample stream at regular intervals by Stallion Uranium geologists and SRC in
accordance with industry-standard quality assurance/quality control ("QA/QC") procedures.
All reported depths and intervals are drill hole depths and intervals, unless otherwise noted, and do not represent
true thicknesses, which have yet to be determined. The reader is cautioned that gamma probe readings are not
directly or uniformly related t o uranium grades of the rock sample measured and should be used only as a
preliminary indication of the presence of radioactive materials.
