STALLION URANIUM COMMENCING GROUND ELECTROMAGNETIC SURVEY ON THE COYOTE CORRIDOR

Stallion Uranium Corp. will commence a high-resolution ground time-domain electromagnetic (TDEM) survey on Nov. 1, 2025, on its Coyote target, part of the Moonlite project in the Athabasca basin in Saskatchewan, Canada, in partnership with Atha Energy Corp.

This survey is designed to extend and refine the results of Stallion's previous EM work, with the goal of precisely defining conductive structures commonly associated with uranium mineralization. The program will focus on the Coyote corridor, home to Stallion's top-priority drill targets identified through detailed analysis of historical data sets and newly acquired geophysical information. These targets were ranked using Stallion's multiparameter review, which applies an 11-step ranking criterion of components for discovery.

Matthew Schwab, chief executive officer of Stallion Uranium, said: "Launching this ground EM survey at the Coyote target is a critical step toward advancing our discovery efforts. By improving the resolution of our geophysical data, we expect not only to sharpen the definition of our highest-priority targets but also to increase the number of drill-ready locations across the Coyote corridor. Each additional high-confidence target strengthens our ability to deliver meaningful results in the upcoming drill campaign."

The survey will be conducted by Abitibi Geophysics using the stepwise moving-loop (SWML) TDEM method, a proven technique for detecting conductive zones within basement rock. Data collected will be fully integrated with the airborne and ground surveys completed earlier in 2025, providing Stallion with an enhanced geophysical model to guide next-stage exploration.

Darren Slugoski, vice-president of exploration, said: "This ground-based survey will significantly improve the resolution of our geophysical data, allowing us to more accurately model conductive features at depth. By integrating the results with our existing data sets, we will be able to fine-tune the positioning of drill collars and reduce the risk of missing mineralized structures. Increasing confidence in the geometry and location of these conductors is essential to maximizing the effectiveness of our upcoming drill program."

Survey results are expected in late November, 2025, and will directly guide final drill targeting. Stallion is preparing to mobilize for a winter drill program in December, 2025, where the refined targets from the Coyote corridor will be tested for potential uranium mineralization.

About the SWML TDEM survey

The SWML TDEM survey utilizes Abitibi's cutting-edge ARMIT-TDEM system, featuring a three-component, combined B-field and dB/dt sensor developed by Dr. James Macnae of the Royal Melbourne Institute of Technology (RMIT). The ARMIT sensor delivers an exceptional signal-to-noise ratio, comparable with a Squid sensor for B-field measurements and an induction coil for B/t detection. It is designed for robust performance across extreme temperatures (minus 40 C to plus 50 C) without the need for hazardous cryogenic liquids.

ARMIT is the only sensor capable of simultaneously measuring both B-field and B/t, ensuring a broad detection range for conductive structures. The system is paired with the state-of-the-art Smartem24 receiver and powered by Abitibi's TerraScope 600-volt transmitter, delivering currents exceeding 25 amperes into the transmitter loop, maximizing the survey's depth penetration and resolution.

Marketing update

In parallel with advancing exploration, Stallion Uranium has engaged specialized marketing firms to expand its market presence and broaden shareholder awareness. These initiatives include targeted digital campaigns, media and content development, and investor outreach programs across North America and Europe. The objective is to ensure Stallion's technical milestones, including the commencement of the Coyote target ground EM survey and the planned January, 2026, drill program, are effectively communicated to both existing shareholders and new audiences.

The company announces that it engaged Danayi Capital Corp. to provide investor relations and marketing services to the company for a term of two months commencing on Sept. 29, 2025, in consideration of an upfront payment of $100,000 (U.S.) pursuant to an agreement dated Sept. 29, 2025. Danayi does not currently own any interest, directly or indirectly, in the company or its securities. The agreement with Danayi remains subject to approval of the TSX Venture Exchange.

Further, the company announces that it engaged Dig Media Inc., doing business as Investing News Network (INN), to provide marketing and advertising services to the company for a term of 10 months commencing on April 8, 2025, in consideration of an upfront payment of $16,800 pursuant to an agreement dated April 8, 2025. INN does not currently own any interest, directly or indirectly, in the company or its securities. The agreement with INN remains subject to approval of the TSX-V.

Coming events

Stallion Uranium will be attending the coming the Catch the Energy Conference taking place at Mount Royal University in Calgary, Alta. Mr. Schwab will be presenting on Saturday, Oct. 18, 2025, at 2:15 p.m. Mountain Time.
