• RC infill drilling returns exceptionally high-grade gold from all five Niagara prospects, confirming a coherent, multi-target gold system across 5km
• 2026 MMS RC program demonstrated a materially larger and higher-grade system than previously understood
• Multiple high-grade intercepts including 8m @ 66.76g/t Au from 101m and 3m @ 52.58g/t Au from 111m

GoldArc Resources Limited (ASX:GA8) is pleased to report high-grade gold assay results from its recently completed Reverse Circulation (RC) drilling program at the Niagara Gold Deposits, within the Company's Leonora South Gold Project. The 85-hole, 5,748m program, 100% funded through the Equity for Drilling Services Agreement with Mineral Mining Services Pty Ltd (MMS) has returned bonanza-grade intercepts across five prospects, potentially identifying Niagara as a high-grade, multi-deposit production hub. The Niagara deposits were previously mined as shallow open-pit operations in the early 1990s at US$300-400/oz, with open-cut mining focusing on accessible near-surface ore. These results materially expand the scale and economic case for the Niagara system. The program returned numerous high-grade intercepts across the five deposits over 5km, demonstrating the depth and lateral scale of the system. Key intercepts include 8m @ 66.76g/t Au from 101m including 1m @ 363.70g/t Au from 102m and 1m @ 130.00g/t Au from 101m in hole 26SPRC014 (Sapphire), 3m @ 52.58g/t Au from 111m including 1m @ 145.00g/t Au from 112m in hole 26ORRC009 (Orion), and 2m @ 47.92g/t Au from 42m including 1m @ 90.20g/t Au from 42m in hole 26JURC006 (Justice). The results confirm a continuous, coherent gold system across a 5km trend, providing the geological footprint and grade inventory to support a potential hub-scale mining operation. GoldArc is now planning to complete initial pit optimisations and preliminary mine schedule at Niagara, as well as progress planned diamond and RC follow-up drilling at the Sapphire bonanza zone.

GoldArc is planning more diamond and RC holes around the high-grade intercepts in order to outline their size, and will complete initial pit optimisations and preliminary mine schedule at Niagara to assess mining scenarios at the current gold price, as a direct precursor to a mining decision.
