Stallion Discoveries Announces 100% Ownership of Horse Heaven Gold & Antimony Project in Central Idaho

VANCOUVER, May 29, 2023 - Stallion Discoveries Corp. (the "Company" or "Stallion") (TSX-V: STUD; OTCQB: STLNF; FSE: HM4) is pleased to announce that the Company has completed its earn-in on the Share Option Agreement dated March 1, 2021 (the "Agreement") pursuant to which the Company has acquired all the shares outstanding in 1262446 B.C. Ltd. ("Horse Heaven Parent"). Horse Heaven Parent is the sole owner of Horse Heaven Holdings Inc. ("Horse Heaven Nevada"). Horse Heaven Nevada holds a 100% interest in the Horse Heaven Project (the "Project").

Horse Heaven Project

The Project is comprised of 699 mining claims covering 14,374 acres in Valley County, Idaho and shares its entire eastern boundary with Perpetua Resources' Stibnite Gold Project. Perpetua Resources' vision is to provide the U.S. with a domestic source of the critical mineral antimony, develop one of the largest and highest-grade open pit gold mines in the country and restore an abandoned brownfield site. The United Stated Forest Service updated the permitting schedule for the Project with a Final Environmental Impact Statement and draft Record of Decision expected by the end of 2023 and a Final Record of Decision anticipated in early 2024.

"The work we have done at Horse Heaven gives our team high confidence in the potential for a significant discovery of both Gold and Antimony. Our belief in the Horse Heaven project comes from our own geological work, but when combined with the continued advancement of the Stibnite Project by Perpetua Resources right next door, we believe this area will be one of the most exiting gold and critical mineral districts in the US," stated Drew Zimmerman, CEO of Stallion Discoveries.

The Project has two zones with historical exploration: the Golden Gate Fault Zone and the Antimony Ridge Fault Zone. The current focus of exploration on the Horse Heaven project is along the 3km Golden Gate Fault Zone(GGFZ), which hosts gold and tungsten mineralization. Stallion has advanced the GGFZ through a 789 sample geochemical survey done in 2021 showing structurally controlled anomalous gold and a CSAMT geophysical survey across the whole zone in 2022. This work along with historical drilling results showing grades of up to 1.51g/t over 36m give Stallion high confidence of strong gold mineralization along the Fault Zone. The team has prepared a 19 pad drill program to test the fault zone and is currently working with the USFS for a drill permit.

Exploration at Antimony Ridge will focus on the area that had historical mining of antimony and will include geological mapping, rock, and soil sampling to delineate if and where a potential geophysical survey would be beneficial. Antimony is classified as a critical mineral in the USA and efforts to delineate significant occurrences of strategic minerals that currently have no domestic production cannot be overlooked, especially with recent inclusion of antimony as a defense shortfall material by the Department of Defense and inclusion in the Homeland Acceleration of Recovering Deposits and Renewing Onshore Critical Keystones Act ("HARD ROCK Act"), a bipartisan bill to bolster domestic production of critical minerals released on June 14, 2022.

Stallion believes the property is underexplored and that along with the two historical zones, there are several other targets that have been identified for further exploration. The Project has year-round road access, close proximity to electrical transmission lines, available access to water rights and a state maintained 1,000m airstrip adjacent to the property.

Stallion's current strategy for the Horse Heaven project requires minimal ongoing capital investment while providing upside potential given the advancement of the adjacent Stibnite Project, one of the largest, high-grade independent gold mines in the United States. The successful permitting of the Stibnite project would create significant value for the area.

Pursuant to the Agreement, the Company has made its final payment of CAD$400,000 and issued 12,000,000 common shares to acquire a 100% interest in Horse Heaven Parent. In total, the Company has paid a total of CAD$1,200,000 and issued an aggregate 36,000,000 common shares over a two-year period. All shares issued pursuant to the Agreement are subject to a hold period of four months and one day from issuance.
