Allegiant Gold begins drill program at Eastside

Mr. Peter Gianulis reports ALLEGIANT BEGINS EXTENSIVE CORE DRILLING PROGRAM TO TEST HIGH GRADE GOLD DISCOVERY AT EASTSIDE PROJECT'S MCINTOSH ZONE Allegiant Gold Ltd. has commenced a 2,000-metre, fully financed diamond core drill program testing the vertical extensions of the high-grade gold discovery at the McIntosh zone within the company's flagship Eastside gold-silver project. To date, approximately 1.4 million ounces of inferred gold and 8.8 million ounces of inferred silver resources have been estimated at the Eastside project with only a small fraction of the project area explored to date. Eastside is located in the prolific Walker Lane trend near the town of Tonopah, Nev. Program highlights: Initial three-hole HQ core drill program (ES-331, ES-337 and ES-338) totalling approximately 2,000 metres as part of a larger 20,000-metre drill program; Holes ES-331 and ES-338 will test the vertical extensions of previously drilled holes ES-239 and ES-243 down to a depth of 600 metres; hole ES-337 is designed to intersect various structures in the high-grade zone discovered in the 2021 drill program and will total a minimum of 600 metres in length; Drilling is under way, with results expected in October and November, 2025. The 2025 core program builds on Allegiant's highly successful 2021 drilling campaign (see news release dated May 26, 2021), which returned the highest-grade intercepts ever reported at Eastside: Hole ES-243: 148 metres of 2.6 grams per tonne gold, including 14 metres of 21.9 g/t Au and 20 metres of 173.8 g/t Ag and ending in 12.2 metres of 2.24 g/t Au; Hole ES-239: 3.1 metres of 39.0 g/t Au at the bottom of the hole, within a broader interval of 111.3 metres grading 1.45 g/t Au. The current program aims to test the vertical continuity and structural controls of this mineralization through deeper core drilling beneath and around holes ES-239 and ES-243, with one angled hole (ES-337) designed to intersect potential mineralized structure at depth. The targets were selected based on a comprehensive review of the company's exploration model incorporating over 60,000 metres of drilling, geophysical, geochemical, lithology and structural data. The exploration model shows a strong correlation between grade and the known structures. Peter Gianulis, chief executive officer, commented: "We are excited to have started our 2025-2026 drill program at Eastside; this is our largest single program ever at Eastside where we anticipate drilling approximately 20,000 metres of reverse circulation and diamond core drilling. We are commencing with diamond core drilling at the McIntosh zone's high-grade zone, which has returned some of the best gold and silver intercepts ever drilled at Eastside. After further interpretation, we are now testing what we believe could be the vertical continuation of these bonanza-grade structures. If successful, this program could redefine the growth potential of the Eastside deposit at depth. Upon completion and interpretation of the property-wide geophysics program, we will begin the reverse circulation drilling of the chosen targets."

About Eastside Eastside is a district-scale, 100-per-cent-owned gold-silver project located in Esmeralda county, Nevada, approximately 30-plus kilometres west-northwest of Tonopah, along the prolific Walker Lane trend. The project hosts a current inferred resource (last updated in July, 2021) of 1.4 million ounces of gold and 8.8 million ounces of silver, with mineralization open to the west, south and at depth. About Allegiant Gold Ltd. Allegiant owns three highly prospective gold projects in the United States, all of which are in the mining-friendly jurisdiction of Nevada. Allegiant's flagship, district-scale Eastside project hosts a large and expanding gold resource and is in an area of excellent infrastructure. Less than 20 per cent of the property has been explored with potential to significantly increase the existing inferred resource. Preliminary metallurgical testing indicates that both oxide and sulphide gold mineralization at Eastside is amenable to heap leaching. We seek Safe Harbor.
