STALLION URANIUM COMMENCES PHASE 1 DRILLING PROGRAM ON MOONLITE PROJECT IN ATHABASCA BASIN

Stallion Uranium Corp. has commenced its 2026 winter diamond drilling program at the Moonlite project, located in the Athabasca basin of Northern Saskatchewan. The drill program will target the Coyote corridor, a large-scale, well-defined structural zone identified through more than a year of integrated geophysical surveys and detailed geological modelling conducted in partnership with Atha Energy Corp. The Moonlite project covers 100-per-cent-owned mineral claims, as well as claims under option with Atha Energy Corp.

Highlights:

• Extensively defined target: The Coyote target is the culmination of over a year of integrated geophysical surveying, geological modelling and multidisciplinary data integration, resulting in a large, well-defined basement-hosted target for high-grade uranium mineralization.
• Compelling geophysical signatures: Priority drill targets are characterized by coincident conductors, gravity anomalies and structural corridors, all features associated with significant uranium deposits in the Athabasca basin.
• First ever drill test of the Coyote corridor: The Coyote structural corridor is a newly defined structural corridor that has never been drill tested.
• Staged drill program under way: Four thousand metres will be drilled utilizing two diamond drill rigs, allowing for results to be incorporated in real time to refine targeting from hole to hole.
• Premier location: The Moonlite project is located within a highly prospective exploration corridor of the western Athabasca basin, near multiple world-class uranium discoveries and deposits.

Drilling is being carried out by Base Drilling, a drilling contractor with extensive experience operating in Northern Saskatchewan and the Athabasca basin.

"This is the first time Coyote has ever been drilled, and it represents one of the most technically compelling uranium targets I have ever seen," said Matthew Schwab, chief executive officer. "After more than a year of focused geophysical work and modelling, we are now testing a target that shows the same geological signatures seen at several major Athabasca uranium discoveries. With two rigs turning, this program has genuine discovery potential."

Drilling commenced later than originally anticipated due to unseasonably warm January weather, which temporarily delayed winter road construction and equipment mobilization. Site conditions have since improved, allowing drilling to start safely and efficiently.

"Coyote checks the boxes we look for in Athabasca uranium exploration," said Darren Slugoski, vice-president, exploration. "We see conductive graphitic structures, gravity lows and structural complexity all coinciding in the same corridor. These are the types of features that host uranium deposits elsewhere in the basin, and this program is designed to test the most favourable parts of that system."

The objective of this program is straightforward: test the most prospective targets of a large, untested structural corridor that displays the key geophysical and geological characteristics associated with high-grade Athabasca uranium deposits.

The 2026 winter drill program is expected to complete approximately six to eight drill holes targeting gravity-low anomalies spatially associated with conductive corridors interpreted to represent graphitic structural zones with potential for uranium alteration. Targeting is focused on areas of interpreted structural complexity, including bends, offsets and breaks in conductive rocks that may provide favourable pathways for uranium-bearing hydrothermal fluids.

Stallion will provide additional updates as drilling progresses and results become available.

Coyote target and exploration rationale

The 2026 winter drill program at the Moonlite project will utilize two diamond drill rigs to complete an estimated six to eight drill holes. The primary focus of the program is to test a series of high-priority target areas defined by recent ground geophysical surveys.

Drill targets are located within gravity-low anomalies spatially associated with conductive corridors, which are interpreted to represent graphitic structural zones with potential for uranium alteration. Targeting within these conductive corridors is focused on areas of interpreted structural complexity, including bends, offsets and breaks in the conductive rocks, which provide favourable pathways and traps for hydrothermal uranium-bearing mineralizing fluids. The Coyote conductive corridor is considered analogous in setting to other productive structural corridors within the Athabasca basin and represents a priority target for initial drill testing.
