GoldArc Completes Largest Leonora South Drilling Campaign as Assays Awaited

Record-Scale Drilling Pushes Leonora South Forward

GoldArc Resources (ASX:GA8) has just completed its largest drilling campaign yet at the Leonora South Gold Project in Western Australia, delivering a hefty 15,260 metres of drilling across 269 holes. This multi-pronged assault combines partner-funded development drilling with aggressive exploration targeting, positioning the company to potentially accelerate resource upgrades and new discoveries in one coordinated push.

The development drilling, fully funded by Mineral Mining Services Pty Ltd (MMS), covered Eclipse, Orion, and Sapphire deposits with 5,734 metres of Reverse Circulation (RC) drilling. This program aims to infill and extend known high-grade zones, such as the previously reported 14m at 7.49 g/t gold at Eclipse, and is designed to underpin a maiden Mineral Resource Estimate and future mine planning. This arrangement with MMS continues to relieve GoldArc shareholders from the typical capital burden of development-stage drilling, a structural advantage highlighted in the company’s recent fully funded $20M development deal.

Exploration Targets and Greenfields Expansion

Alongside development drilling, GoldArc completed a 3,186m advanced RC program at the Cosmopolitan deposit and the Whistler and Woodpecker prospects. The Woodpecker target remains particularly compelling following an earlier standout aircore intercept of 1m at 25.21 g/t gold, suggesting significant upside in a corridor that has seen limited systematic drilling to date.

Complementing this, a substantial 6,340m greenfields aircore program comprising 152 holes was executed across Whistler, Cosmopolitan South, and Altona South. These greenfields efforts systematically test multiple drill-ready targets along favourable structural trends in the broader Kookynie district, aiming to delineate the extent of mineralised systems and identify new advanced targets.

Assay Results and Next Steps

All assay results from these three programs are expected by the end of May 2026. GoldArc’s Managing Director Paul Stephen emphasised the importance of this milestone, noting the substantial dataset will refine geological understanding and guide prioritisation for follow-up drilling and development. The company anticipates a strong news flow as results arrive, which will be critical in shaping the next phase of exploration and potential resource upgrades.

This drilling campaign builds on GoldArc’s broader strategy to grow its existing 200,000-ounce JORC resource base while pursuing new large-scale discoveries in the Eastern Goldfields. The combined approach of partner-funded development drilling and aggressive exploration is designed to balance risk and capital efficiency as the company advances towards production readiness.
