Allegiant Gold Launches Diamond Core Drill Program at Eastside Gold-Silver Project

Tonopah, Nevada — September 10, 2025 — Leads & Copy — Allegiant Gold Ltd. has commenced a 2,000-meter diamond core drill program at its Eastside Gold-Silver Project, targeting vertical extensions of the high-grade gold discovery at the McIntosh zone. The program is fully funded and aims to test the continuity of mineralization at depth.

The Eastside Project, located in the Walker Lane Trend, has an estimated inferred resource of 1.4 million ounces of gold and 8.8 million ounces of silver. The current drill program builds on the successful 2021 campaign, which yielded high-grade intercepts, including 148 meters of 2.6 g/t Au and 3.1 meters of 39.0 g/t Au.

The initial phase includes three core drill holes (ES-331, ES-337, ES-338), with results expected in October and November 2025. The program will test vertical extensions of previously drilled holes and intersect structures in the high-grade zone.

CEO Peter Gianulis stated that this is Allegiant's largest single program at Eastside, with approximately 20,000 meters of drilling planned. The company aims to redefine the growth potential of the Eastside deposit at depth.
