Allegiant Selects Company for Core Drilling Program at Eastside

2,000-Metre Drill Program to Test Depth Extensions of High-Grade Zone

Tonopah, Nevada / July 21, 2025 - Allegiant Gold Ltd. (“Allegiant” or the “Company”) (AUAU: TSX-V) (AUXXF:

OTCQX) is pleased to announce the selection of Timberline Drilling Inc., based in Elko, Nevada, to conduct a 3-

hole, up to 2,000-metre diamond core drill program at its flagship Eastside Project located near Tonopah,

Nevada.

The program will target the High-Grade Zone (HGZ) within the McIntosh Zone and is designed to follow up on

the most successful drill holes in the Company’s history. Drilling is anticipated to commence within the next 2

to 3 weeks.

PROGRAM HIGHLIGHTS:

• Drill Contractor: Timberline Drilling Inc. of Elko, Nevada

• Program: Up to 2,000 metres of HQ diamond core drilling in 3-4 holes

• Drill Holes:

o ESC-321 and ESC-322: New vertical core holes to be drilled to depths of over 600 metres each,

following up on prior bonanza-grade intercepts in ES-239 and ES-243, last drilled in 2021

o ES-323: A newly designed 65-degree angle hole, totaling 740 metres (approximately 660 metres

vertical depth) to test deeper structural controls and the potential for high-grade mineralization

Peter Gianulis, CEO of Allegiant Gold, commented: "After a significant amount of analysis and reinterpretation,

we are now set to test the vertical extensions of the two most successful holes in the Company’s history. This

program will test for continuity and potential expansion of the High-Grade Zone at depth. If successful, it could

represent a major step toward re-rating Eastside as one of Nevada’s most exciting gold-silver projects.”

This program is supported by Allegiant’s updated exploration model, which incorporates over 60,000 metres of

historical drilling along with recent structural, lithological, geochemical, and geophysical datasets. Drilling results

will inform future exploration planning and potential resource updates.
