Stallion Uranium Defines Priority Target Areas From VTEM Survey On Stone Island Target, Moonlite Project Stallion Uranium Corp. has completed its interpretation of the VTEM dataset, integrated with magnetic tilt derivative data, and defined multiple priority conductive trends and structurally controlled target areas for follow-up exploration. The VTEM Plus survey, completed by Geotech Ltd., consisted of two grids located south of the Company’s flagship Coyote Target and was designed to refine conductive structural corridors and identify additional drill targets across the broader Moonlite property. Integrated VTEM Plus and magnetic tilt interpretation defines four priority target areas at (A–D) Stone Island. Strong to moderate Tau responses delineate graphitic basement conductors, consistent with uranium-bearing systems in the Athabasca Basin. Multiple parallel to sub-parallel conductive trends identified, outlining a broad structural corridor. Magnetic tilt derivative highlights structural breaks, offsets, and cross-cutting lineaments, enhancing interpretation of fault-controlled architecture. Priority targets occur along conductor margins and zones of structural disruption, favourable for uranium mineralization. Plate modelling and inversion are underway to refine conductor geometry, depth, and drill targeting. The VTEM Plus data has outlined a strong conductive corridor with multiple parallel trends, and magnetic tilt interpretation has highlighted the structural controls on these conductors. The first completed drill hole at Coyote intersected graphitic faulting and significant alteration, providing strong validation of the geophysical targeting approach. The company is now focused on refining these targets through modelling and advancing them toward systematic drill testing. Interpretation of the VTEM Plus Tau data has defined a broad conductive corridor across the Stone Island Target, characterized by moderate to high time constant (“Tau”) responses. These conductive trends are interpreted to represent graphitic basement structures commonly associated with unconformity-related uranium systems in the Athabasca Basin. Integration with magnetic tilt derivative data has enhanced structural interpretation, highlighting lineaments, offsets, and cross-cutting features interpreted as fault structures. These features commonly correspond spatially with conductive trends and areas of anomaly complexity. Four priority target areas (A–D) have been identified based on the spatial relationship between conductive trends and interpreted structural features: Target A (NE Block) - Located along the western portion of the northeast survey block, this target corresponds to a moderate to high Tau response situated along the margin of a primary conductor. The anomaly exhibits subtle changes in geometry and is interpreted to represent a structurally influenced segment of the conductive corridor. Target B (NE Block) - Positioned in the northwestern portion of the northeast block, this target is associated with a strong conductive response and increased structural complexity, including possible offsets and disruption within the conductor. Target C (NE Block) - Located in the southeastern portion of the northeast block, this area is defined by a coherent conductive trend with localized complexity, interpreted to represent a continuation of the broader structural corridor. Target D (SW Block) - Situated along the eastern margin of the southwest survey block, this target represents a distinct conductive anomaly with localized structural complexity and is interpreted as a discrete segment of the conductive system. These targets are primarily located along conductor margins and zones of structural disruption, where fluid flow and uranium deposition are most likely to occur. Plate modelling and inversion of the VTEM dataset are currently in progress and will further constrain conductor geometry, depth, and continuity. These results will be used to refine drill targeting and guide future exploration programs on the Moonlite Project. Concluding February 19, 2026, Geotech Ltd. carried out a helicopter-borne geophysical survey at the request of Stallion Uranium Corp. The survey totaled approximately 676 line-kilometres across two blocks over the Stone Island Target on the Moonlite property. The VTEM Plus (Versatile Time Domain Electro Magnetic) system is the most innovative and successful airborne electromagnetic system to be introduced in more than 30 years. The proprietary receiver design using the advantages of modern digital electronics and signal processing delivers exceptionally low-noise levels. Coupled with a high dipole moment transmitter, the result is unparalleled resolution and depth of investigation in precision electromagnetic measurements. Key features include: Superior Exploration Depth - over 800 metres in certain environments. Low Base Frequency (30 Hz) for penetration through conductive cover. High Spatial Resolution - 2 to 3 metres. Improved Interpretability due to Receiver-Transmitter symmetry. Ability to identify drill targets directly from airborne results. Excellent resistivity discrimination and detection of weak anomalies. The system was designed to be field configurable to best suit a large variety of different geophysical requirements from deep penetration to optimizing the discrimination within a narrow range of resistivity values. The system is easily transportable. It can be disassembled for packaging in relatively small units for shipping to surveys around the world. In the event of damage to the EM bird in-flight or while being transported between survey sites, the unique design allows the easy replacement of any part of the system in the field. The transmitter loop can be assembled or disassembled in 6-8 hours. Board Change • Jul 03

Stallion Uranium Corp. Intersects Elevated Radioactivity And Alteration At Coyote And Continues Expanded Drill Program Stallion Uranium Corp. provided an update on drilling activities at its Coyote target, part of the Moonlite project in the Southwest Athabasca Basin, Saskatchewan, Canada in partnership with Atha Energy Corp. The Company also announces the mobilization of an expanded high-resolution ground Time Domain Electromagnetic (TDEM) along Coyote target corridor and over the current drilling target. Stallion Uranium Corp. has continued to make strong progress at the Moonlite Project since its last drilling update on April 28, 2026. At that time, approximately 1,900 metres of the planned 4,000-metre drill program had been completed. Positive results from the initial drill holes prompted the Company to expand the Phase 1 program at the Coyote target to 5,500 metres. To date, approximately 3,527 metres have been completed, with drilling continuing to advance as planned. The early results are promising: elevated radioactivity (>300 cps) was intersected in all of the first three completed holes on the main Coyote target. Every hole has also revealed substantial hydrothermal alteration and strong structural features within the sandstone and underlying basement rocks. The discovery of a graphitic fault zone alongside pronounced structural complexity and alteration provides robust confirmation of the Company’s integrated geophysical model. These findings highlight a structurally active and hydrothermally altered corridor at Coyote, consistent with a fertile uranium system. These intersections, particularly the graphitic fault zone within a broader zone of structural complexity and alteration validate the Company’s geophysical model and underscore the presence of a well-developed hydrothermal system at the Coyote target. Stallion remains fully funded to complete the current program, and shareholders can look forward to several upcoming milestones as the discovery effort advances: Completion of the remaining expanded 5,500-metre Phase 1 drill program; Results from the expanded SWML-TDEM ground survey, which will help refine targeting for future drilling; Laboratory geochemical assay results from drill core, which provide the definitive measurement of uranium grade. All initial core radioactivity was measured using a RS-125 Super-SPEC Handheld Gamma-Ray Spectrometer. Down hole probing radiometric surveying was conducted with a Mount Sopris QL40GR-1000, Total Count Natural downhole Gamma Probe. The total gamma results provided in Table 1 were selected using a cut-off of 200 cps over a 0.3 metre downhole width. 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 to uranium grades of the rock sample measured and should be used only as a preliminary indication of the presence of radioactive materials. The foregoing scientific and technical disclosures for Stallion Uranium have been reviewed and approved by Darren Slugoski, P.Geo., VP Exploration, a registered member of the Professional Engineers and Geoscientists of Saskatchewan. Mr. Slugoski is a Qualified Person as defined by National Instrument 43-101.
