VANCOUVER, British Columbia, July 23, 2026 (GLOBE NEWSWIRE) -- Stallion Uranium Corp. (the "Company" or "Stallion ) (TSX-V: STUD OTCQB: STLNF FSE: B76) is pleased to announce the successful completion of an expanded ground gravity survey at its flagship Coyote target. The survey has delineated multiple new high-priority uranium drill targets while significantly extending the prospective strike length of the Coyote exploration corridor within the Moonlite Project, part of the southwestern Athabasca Basin Joint Venture ("JV") with Atha Energy Corp. ("Atha Energy") (TSX-V: SASK)
Matthew Schwab, CEO of Stallion, said, "Through every step of this exploration program we continue to strengthen our confidence in the Coyote corridor. The expanded gravity survey has materially increased the number of high-priority drill targets while further validating the geological model we have been building over the past several years. As we continue integrating each dataset, we're seeing a larger and more compelling exploration system emerge."
"The integration of multiple independent geophysical datasets continues to refine drill targeting while systematically reducing geological risk across the Coyote Corridor."
Completed in two phases, the expanded gravity survey significantly increased coverage across the interpreted Coyote conductive corridor. The expanded survey builds upon the Company's previously announced gravity results dated July 14, 2025 and provides substantially greater coverage across the interpreted conductive corridor.
The new data further enhances Stallion's understanding of the structural architecture controlling uranium mineralization and has identified several additional gravity low anomalies spatially associated with conductive trends interpreted from MobileMT and ground TDEM surveys.
Highlights:
- Expanded gravity survey identifies multiple new high-priority drill targets.
- Five integrated target areas now defined across the Coyote corridor.
- Several gravity lows occur at structural intersections recognized as favourable settings for Athabasca uranium deposits.
- Survey significantly expands prospective strike length beyond the original target area.
- Integrated geological model further strengthens confidence in future drilling.
- Five priority drill target areas (A-E) identified where gravity lows coincide with interpreted structures and conductive corridors.

Gravity Survey Extension:
The expanded gravity program was designed to extend coverage beyond the original western survey area following encouraging results announced earlier this year, which identified a prominent gravity low coincident with interpreted basement structures and conductive trends.
The eastern extension has successfully expanded the survey footprint across the remainder of the interpreted conductive corridor, resulting in the identification of several additional discrete gravity low features (Figure 1). The gravity lows occur within areas interpreted to contain significant structural complexity and are spatially associated with electromagnetic conductors interpreted from previous MobileMT, HeliSam and ground TDEM surveys.
The integrated dataset now outlines multiple priority target areas distributed along the Coyote corridor outside of the previous survey area, providing several compelling targets for future drill testing. Collectively, these targets represent some of the highest-priority drill opportunities identified on the Coyote Corridor to date.
In the Athabasca Basin, gravity lows are commonly associated with hydrothermal alteration and structural disruption. When these features coincide with graphitic conductors and fault intersections, they become highly attractive uranium drill targets.

Integrated Geological Model
Following completion of the gravity survey extension, Stallion integrated the new gravity data with previously completed MobileMT, ground TDEM, magnetic, and structural interpretations to generate an updated three-dimensional exploration model (Figure 2).
The gravity inversion suggests several gravity low features extend beneath the unconformity and are associated with interpreted fault intersections and graphitic conductive horizons. These relationships are consistent with the structural setting observed at numerous significant Athabasca Basin uranium deposits, where hydrothermal alteration commonly produces localized density reductions adjacent to reactivated basement structures.
The updated geological model will be used to refine future drill collar locations and prioritize exploration across the broader Coyote corridor.
Gravity Data Inversion:
Convolutions Geoscience inverted the ground gravity data, utilizing industry-standard 3D inversion techniques to estimate subsurface density variations from the processed gravity data. The objective was to assist in delineating alteration zones of interest for uranium exploration.
Convolutions Geoscience carried out a 3D inversion of the gravity data to create a voxel product of subsurface density anomalies using the industry-standard Fullagar Vertical Prism Magnetic and Gravity (VPmg) codes. The inputs into the inversion were the free air anomaly from the dataset; lake bathymetry data for water depth; digital terrain model (DTM) for the project area, in addition to NASA Shuttle Radar Topography Mission (SRTM) data for surrounding areas; and density constraints for sandstone cover rocks above the unconformity as well as basement rocks below the unconformity. Convolutions created a VPmg gravity inversion using 40m x 40m surface XY blocks and Z blocks of 10m at the surface, increasing by 5% at depth. The total model block depth exceeds 10km.
Next Steps:
The newly identified gravity targets will be incorporated into Stallion's upcoming drill planning, with priority given to areas where gravity lows coincide with conductive corridors and interpreted basement structures. The Company believes these integrated targets represent some of the highest-priority exploration opportunities identified to date on the Coyote Corridor and will form the foundation of future drill campaigns.
