Stallion Discoveries and ATHA Energy Corp. Form Option for Joint

Venture Creating the Largest Contiguous Project in the Western

Athabasca Basin

Stallion Potentially Quadruples Land Position in World Class Uranium District

Vancouver, British Columbia, May 16, 2023 – Stallion Discoveries Corp. (the "Company" or "Stallion") (TSX-

V: STUD; OTCQB: STLNF ; FSE: HM4 ) is pleased to announce that the Company has entered into a binding

letter of intent with Atha Energy Corp. (“Atha”) (CSE: SASK) pursuant to which the Company and Atha shall

seek to enter into definitive agreements which shall give the Company an option (the “Option”) to acquire a

70% interest in 47 mineral claims covering 547,524 acres in Saskatchewan’s prolific Western Athabasca Basin

(the “Project”) by acquiring the requisite interest from Atha, which currently holds a 90% interest in the

Project.

The addition of the Project to Stallion’s existing holdings is expected to significantly expand the Company’s

land package in the Western Athabasca Basin to total 715,450 acres. Should the Option be exercised, the

Company may hold an aggregate 692,647 acres that could form the largest contiguous project in the Western

Athabasca basin . This Project’s lands, together with the Company’s current holdings , share significant

borders with projects held by Cameco Corporation, Orano Canada Inc., NexGen Energy Ltd., Denison Mines

Corp. and F3 Uranium Corp., as illustrated in Figure 1. The scale and strategic location of the asset base is

expected to provide numerous high-potential target zones along several major trends as Stallion continues

its exploration efforts.

“We are thrilled to announce this transformational option to expand our position in the Western Athabasca

basin. There is significant strategic value in gaining access to this land package that is directly adjacent to our

current projects. We and other key stakeholders in the district believe that the Western Basin is

underexplored and provides tremendous opportunity for exploration success. Stallion now has the potential

to hold the largest continuous land package in the Western Athabasca basin, offering exploration synergies

and more potential target areas as we execute on our exploration plan ,” stated Stallion CEO, Mr. Drew

Zimmerman.

As previously announced on March 1, 2023, the Company has commenced the first phase of its exploration

program in the Athabasca Basin, completing the data acquisition phase announced on April 27, 2023, and

will provide further updates to the program in the coming weeks.

Key Terms:

• During the term of the Option, Stallion will be the sole operator of all exploration programs on the

Project.

exercisable for one year thereafter. Milestones include:

o i) issuance of 3,333,333 shares of Stallion within two business days following the definitive

agreement
