STALLION URANIUM DEFINES PRIORITY TARGET AREAS FROM VTEM SURVEY ON STONE ISLAND TARGET, MOONLITE PROJECT

Stallion Uranium Corp. has provided 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 data set, 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, chief executive officer 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 (A to D) at Stone Island;
• Strong to moderate Tau responses delineate graphitic basement conductors, consistent with uranium-bearing systems in the Athabasca basin;
• Multiple parallel to subparallel conductive trends identified, outlining a broad structural corridor;
• Magnetic tilt derivative highlights structural breaks, offsets and crosscutting 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 under way 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 crosscutting 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 to D) have been identified based on the spatial relationship between conductive trends and interpreted structural features:

• Target A (northeastern block): Located along the western portion of the northeastern 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 (northeastern block): Positioned in the northwestern portion of the northeastern block, this target is associated with a strong conductive response and increased structural complexity, including possible offsets and disruption within the conductor.
• Target C (northeastern block): Located in the southeastern portion of the northeastern 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 (southwestern block): Situated along the eastern margin of the southwestern 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 data set 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 Feb. 19, 2026, Geotech carried out a helicopter-borne geophysical survey at the request of Stallion Uranium. The survey totalled approximately 676 line kilometres across two blocks over the Stone Island target on the Moonlite property.

The VTEM Plus 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 hertz) for penetration through conductive cover;
• High spatial resolution -- two to three 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 electromagnetic bird inflight 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 six to eight hours.
