Stallion Uranium Commences Phase II Drilling at Moonlite Project

VANCOUVER, British Columbia, Sept. 29, 2026 /CourierPR/ -- Stallion Uranium Corp., a company listed on the TSX Venture Exchange (STUD), the OTCQB (STLNF), and the Frankfurt Stock Exchange (FSE: B76), is pleased to announce the recommencement of diamond drilling at the Coyote target on its flagship Moonlite Project in the Athabasca Basin, Saskatchewan, part of the southwestern Athabasca Basin Joint Venture with Atha Energy Corp. (SASK).

With approximately 2,165 metres remaining, Stallion's focus is straightforward: deploying those metres into the highest-priority areas identified by their technical team. They believe the integration of drilling, geophysics, and structural interpretation has given them their clearest picture of Coyote to date and provides a strong foundation for this next phase of drilling.

Drilling crews have been mobilized to Coyote to begin Phase II of Stallion's expanded 2026 drilling campaign. The Company has completed approximately 4,585 metres of the planned 6,750-metre program, leaving approximately 2,165 metres of drilling to be completed during the current phase.

Phase II will build directly on the geological, structural, and radiometric information generated during the first phase of drilling and will continue testing priority areas along the Coyote corridor. SRK Consulting has completed a regional-scale Structural Interpretation and Targeting Assessment designed to identify the primary and secondary structural controls associated with uranium mineralization in the western Athabasca Basin. The assessment provides Stallion with an additional framework for interpreting potential structural conduits and traps at Coyote and has been incorporated into the Company's Phase II targeting.

Information collected from drilling completed to date has been integrated with Stallion's geological interpretation, structural analysis, and expanding geophysical dataset to refine the Company's Phase II drill targets. The remaining approximately 2,165 metres of drilling will focus on the highest-priority areas identified through this integrated targeting approach.

Stallion intends to use the remaining 2026 drilling to continue evaluating the geological and structural controls encountered during the program while testing additional high-priority positions within the Coyote system. Advancing Coyote through an expanding dataset is a key part of their exploration strategy.

The 2026 program represents the first systematic drill testing of the Coyote target and has provided Stallion with a significantly improved understanding of the geology and structural architecture underlying the corridor. Stallion began 2026 with an initial 4,000-metre drilling program at Coyote. As drilling progressed and additional geological and geophysical information became available, the program was first expanded to 5,500 metres and subsequently to approximately 6,750 metres. Rather than simply adding metres to the original drill plan, the expanded program has allowed Stallion's technical team to continuously refine subsequent drill locations as new information has been generated.

The commencement of Phase II represents the next stage of that process, with the remaining holes incorporating the Company's most complete geological and geophysical interpretation of Coyote to date. Stallion intends to use the remaining 2026 drilling to continue evaluating the geological and structural controls encountered during the program while testing additional high-priority positions within the Coyote system.

Gamma Logging and Geochemical Assaying: All core radioactivity is measured using an RS-125 Super-SPEC Handheld Gamma-Ray Spectrometer. Downhole radiometric surveying is conducted using a Mount Sopris QL40GR-1000 downhole total gamma probe. Drill core samples from the 2026 program are shipped to the Saskatchewan Research Council Geoanalytical Laboratories (SRC) in Saskatoon, Saskatchewan, an ISO/IEC 17025 accredited analytical laboratory. Stallion requests multi-element analysis by ICP-MS and ICP-OES using total and partial digestion, with boron analyzed by fusion. One half of the split core is retained and the other half is submitted to SRC for analysis.

Stallion Uranium Corp. will provide additional updates as Phase II drilling progresses and results become available. The Company will also present at the Schachter Catch the Energy Conference in Calgary, Alberta, on Saturday, October 17, at 11:45 a.m. MDT, providing an update on the Company's 2026 exploration activities and discussing its ongoing exploration strategy.
