Stallion Uranium Corp. (the ‘Company’ or ‘Stallion’) (TSX-V: STUD; OTCQB: STLNF; FSE: B76) is pleased to announce the mobilization of an expanded high-resolution ground gravity survey on its Coyote Target corridor, located in the Athabasca Basin of northern Saskatchewan, Canada.

The current program is designed to extend the results of Stallion’s previous ground gravity survey by expanding coverage to the west of the original survey area. Mobilization is commencing, with the objective of identifying additional gravity lows and refining the geometry and continuity of anomalies identified at the margins of the earlier survey.

Highlights:

• The expanded survey aims to identify additional gravity lows associated with interpreted density destruction in the basement rocks, which may reflect hydrothermal alteration systems linked to uranium mineralization
• Particular focus will be placed on gravity lows identified along the edges of the previous survey, several of which remain open and poorly constrained
• Extending coverage westward will improve the understanding of the size, orientation, and continuity of priority anomalies at the Coyote Target
• High-resolution ground gravity surveying has been successfully applied in the Athabasca Basin to identify alteration-related density lows, including its use in the discovery of NexGen Energy’s PCE uranium deposit
• Survey results will be integrated with existing geological, geochemical, and geophysical datasets to further refine priority drill targets
• The program is being conducted by MWH Geo-Surveys Ltd., utilizing ground gravity methods effective for mapping basement-hosted alteration systems

Darren Slugoski, Vice President of Exploration for Stallion Uranium, said, ‘Extending the ground gravity survey is important not only for refining existing anomalies, but also for identifying additional target areas along the broader Coyote conductive trend. In the Athabasca Basin, multiple uranium deposits are known to occur along the same structural corridor, as demonstrated by the Patterson Lake corridor. Expanding coverage beyond the original survey boundaries will help us better define the continuity of alteration-related gravity lows and evaluate the potential for multiple uranium systems along the Coyote Trend.’

Kyle Patterson, P.Geo., President of Convolutions Geoscience Corp., said, ‘Review of the existing gravity inversion suggests that key density lows at Coyote are not fully constrained at the western edge of the current survey coverage. Extending the ground gravity program is a logical next step to better define the geometry and continuity of these features, which may be associated with basement-hosted alteration systems. Improved spatial definition will strengthen target ranking and help guide future exploration decisions.’

Coyote Target and Exploration Rationale:

The Coyote Target was selected following a comprehensive technical evaluation of historical and recently acquired datasets, including geological mapping, geochemistry, and multiple geophysical surveys. The target exhibits characteristics consistent with basement-hosted uranium systems in the Athabasca Basin, where hydrothermal alteration commonly results in interpreted density destruction that can be effectively delineated using high-resolution ground gravity surveys.

Stallion Uranium continues to apply disciplined, data-driven exploration techniques to systematically advance its portfolio of uranium projects within the Athabasca Basin.

About the Ground Gravity Survey:

MWH Geo-Surveys uses customized L&R digital, electronic feedback gravity meters operated via proprietary controller software. These gravity meters, which incorporate electronic levels and electronic nulling, are fast, accurate and exceptionally reliable, particularly in cold weather operations. The digital output from the meter is captured via a Bluetooth link by GControl, software developed by MWH Geo-Surveys operating on a Juniper Archer field PC.

At each gravity station, GControl records gravity samples at 1 second intervals; the resultant average of these records is used as the final gravity reading, thereby removing much of the high frequency noise, such as that caused by wind and ground motion. GControl also calculates precise real-time, location specific tidal corrections during data collection.

With a typical mean data accuracy of 0.02 mgals, MWH Geo-Surveys continues to set the standard for high-resolution gravity surveys, delivering reliable results for resource exploration and geophysical studies.

About Skyharbour Resources Ltd.:

Skyharbour holds an extensive portfolio of uranium exploration projects in Canada’s Athabasca Basin and is well positioned to benefit from improving uranium market fundamentals with interest in forty-three projects covering over 662,887 hectares (over 1.6 million acres) of land. Skyharbour owns a 100% interest in the Moore Uranium Project, which is located 15 kilometres east of Denison’s Wheeler River project and 39 kilometres south of Cameco’s McArthur River uranium mine. Moore is an advanced-stage, uranium exploration property with high-grade, shallow uranium mineralization at the Maverick Zones. Adjacent to Moore, Skyharbour is advancing several uranium properties within the Russell Lake project area with its joint venture partner and large strategic shareholder Denison Mines. Collectively these projects host multiple zones of high-grade uranium mineralization across a highly prospective land package with significant exploration upside, and the Company is actively working these assets through exploration and drilling programs.

Skyharbour now has joint ventures with industry-leaders Denison Mines and Orano Canada Inc. at the Russell Lake properties and the Preston project, respectively. The Company also has several active earn-in option partners, including CSE-listed Nexus Uranium Corp. at the Mann Lake Uranium Project; TSX-V listed North Shore Uranium at the Falcon Project; UraEx Resources at the South Dufferin and Bolt Projects; Hatchet Uranium at the Highway Project; CSE-listed Mustang Energy at the 914W Project; and TSX-V listed Terra Clean Energy at the South Falcon East Project. In aggregate, Skyharbour has now signed earn-in option agreements with partners that total to potentially over $76 million in partner-funded exploration expenditures and over $42 million in cash and share payments coming into Skyharbour, assuming that these partner companies complete the earn-ins at their respective projects.

Skyharbour’s goal is to maximize shareholder value through new mineral discoveries, committed long-term partnerships, and the advancement of exploration projects in geopolitically favourable jurisdictions.
