Allegiant Gold begins drill program at Eastside

Executive Summary

• Allegiant Gold Ltd. has launched a fully‑financed 2,000 m diamond core drill program at the McIntosh zone of its Eastside gold‑silver project, part of a larger planned 20,000 m campaign.
• The initial three holes (ES‑331, ES‑337, ES‑338) will test vertical extensions of high‑grade intercepts previously reported in 2021, with results expected October–November 2025.
• Successful drilling could substantially increase the inferred resource and redefine the growth potential of the Eastside deposit at depth.

Key Details

• Program Scope: 2,000 m initial HQ core program (holes ES‑331, ES‑337, ES‑338) within a planned 20,000 m drill campaign (both reverse‑circulation and diamond core).
• Target Zones:
• ES‑331 & ES‑338 – vertical extensions of historic holes ES‑239 and ES‑243 down to ~600 m depth.
• ES‑337 – angled hole designed to intersect additional structures in the high‑grade zone, minimum 600 m length.
• Historical High‑Grade Intercepts (2021):
• Hole ES‑243: 148 m @ 2.6 g/t Au (including 14 m @ 21.9 g/t Au and 20 m @ 173.8 g/t Ag).
• Hole ES‑239: 3.1 m @ 39.0 g/t Au within a broader 111.3 m interval @ 1.45 g/t Au.
• Resource Context: Eastside currently holds ~1.4 Moz inferred gold and ~8.8 Moz inferred silver (July 2021 estimate); only a small portion of the project has been explored.
• Exploration Model: Based on >60,000 m of drilling, geophysics, geochemistry, lithology, and structural data; shows strong grade‑structure correlation.
• Timeline: Drilling underway; assay results anticipated in October–November 2025.
• Future Plans: Upon completion of property‑wide geophysical work, reverse‑circulation drilling will commence on additional targets.
