HIGH-GRADE GOLD SYSTEM CONFIRMED AT ECLIPSE AND CHALLENGE

Final 1-metre assays reveal robust mineralised zones within Leonora South Gold Project

GoldArc Resources Limited (ASX:GA8) has announced the final 1-metre assay results from its recent reverse circulation (RC) drilling campaign at the Eclipse and Challenge prospects, part of the Leonora South Gold Project near Kookynie in Western Australia.

The company reports that results from its 40-hole RC program, completed by the end of July 2025, have confirmed and expanded the extent of high-grade, near-surface gold mineralisation — particularly at Eclipse, where a structurally controlled gold system has been defined.

Standout intersections from Eclipse include:

14m at 7.49 g/t Au from 12m in hole NIC017
2m at 7.50 g/t Au from 88m in hole NIC023
4m at 5.20 g/t Au from 78m in hole NIC034
6m at 3.14 g/t Au from 60m in hole NIC024
5m at 3.40 g/t Au from 35m in hole NIC037

GoldArc stated that the mineralised system at Eclipse remains open along strike and at depth, pointing to strong potential for resource growth with further drilling. These latest results are expected to form the basis for a maiden Mineral Resource Estimate (MRE) at Eclipse.

At the nearby Challenge prospect, drilling also intercepted promising shallow mineralisation:

3m at 5.55 g/t Au from 38m in hole NIC044
2m at 2.85 g/t Au from 14m in hole NIC053
6m at 2.35 g/t Au from 34m in hole NIC040

Both prospects lie within the broader Leonora South Gold Project, which is situated near the historic Orion and Sapphire Gold Mines, currently hosting a Mineral Resource Estimate of 48,000oz at 2.2g/t Au.

GoldArc Resources Managing Director, Paul Stephen commented:
Following our initial high-grade intercept, we have been eagerly awaiting these 1-metre gold results to understand the broader potential of the system. Crucially, they show that our initial hit was not an isolated occurrence, but part of a potentially larger mineralised system that we are now beginning to unlock. The system at Eclipse remains open in all directions and we see a clear and immediate opportunity to grow our resource base.

Our team is already finalising drill targets across the Leonora South and North project areas, with the goal of maintaining this level of exploration output. This success underpins a period of increased activity for the Company as we work to grow our existing resource base and uncover the potential of our entire Leonora landholding.
