Auld Creek Exploration Results - October

Rua Gold Inc. (TSX: RUA, NZX: RGI, OTC: NZAUF, WKN: A40QYC) (“RUA GOLD" or the "Company") is pleased to provide an update on exploration and resource drilling at its Auld Creek gold-antimony project (the “Auld Creek Project”) in Reefton, New Zealand. Highlights: • Four drill rigs continue to advance resource drilling across the growing Auld Creek system, which remains open along strike and at depth. • Recent drilling continues to intersect high-grade gold-antimony mineralization, including narrow zones of exceptional gold grades in ACDDH127 and ACDDH130 of 0.3m at 43.6 g/t Au (>1 oz/t Au) and 0.3m at 69.2 g/t Au (>2 oz/t Au), respectively. Visible gold continues to be observed in drill core. • Highlighted assay results from drilling at Auld Creek include: o ACDDH121: 11.7m @ 5.0 g/t AuEq2 (4.1 g/t Au & 0.4% Sb) from 365m o ACDDH123A: 2.2m @ 34.6 g/t AuEq2 (10.3 g/t Au & 11.3% Sb) from 228m o ACDDH123B: 5m @ 7.4 g/t AuEq2 (4.8 g/t Au & 1.2% Sb) from 236m o ACDDH127: 6.6m @ 24.9 g/t AuEq2 (10.5 g/t Au & 6.7% Sb) from 359m Incl 0.3m @ 43.6 g/t Au and 33.3% Sb o ACDDH130: 6.3m @ 14.4 g/t AuEq2 (13.7 g/t Au & 0.3% Sb) from 208m Incl 0.3m @ 69.2 g/t Au • Drilling continues to demonstrate continuity of the shallow-dipping mineralized shoots along strike. Repeating shoots at depth, occurring at approximately 40m intervals, support the potential for further resource growth to the north and at depth. • Four drill rigs remain focused on resource development ahead of an updated Mineral Resource Estimate targeted for Q4 2026. • The Company remains on track to submit its substantive application under New Zealand’s Fast-Track Approvals regime in October 2026.
