VANCOUVER, British Columbia, July 07, 2026 (GLOBE NEWSWIRE) -- Stallion Uranium Corp. (the “Company” or “Stallion”) (TSX-V: STUD; OTCQB: STLNF; FSE: B76) is pleased to provide an update on its recently completed Versatile Time Domain Electromagnetic (“VTEM”) Plus airborne electromagnetic survey and magnetic interpretation over the Stone Island Target, on its Moonlite Project in the Southwestern Athabasca Basin.

The Company 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.

Matthew Schwab, CEO of Stallion, said, “We are now clearly defining multiple priority target areas at the Stone Island Target through the integration of VTEM and magnetic data. The identification of several discrete targets significantly expands our exploration pipeline and reinforces the broader potential of the Moonlite Project within the Southwestern Athabasca Basin.”

Highlights:

• 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.

Darren Slugoski, Vice President Exploration, added, “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. Importantly, our first completed drill hole at Coyote intersected graphitic faulting and significant alteration, providing strong validation of our geophysical targeting approach. We are now focused on refining these targets through modelling and advancing them toward systematic drill testing.”

VTEM Plus and Magnetic Interpretation - Stone Island Target:

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.

Defined Target Areas:

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.

About the VTEM Plus Survey:

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.
