GoldArc Resources has completed its reverse circulation grade control program at the Mt Stirling Well deposit within the Leonora North hub, returning a standout final intercept of 1 metre at 59.9 g/t gold from 24 metres in hole 26BSWRC973.

The sixth and final round of drilling covered assay batches 35, 36, and 37, encompassing 50 holes for approximately 1,248 metres. This brings total drilling across the combined campaign to approximately 28,785 metres. The final batch delivered seven additional intercepts above 10 g/t gold, including 1 metre at 32.7 g/t gold from 30 metres and 3 metres at 14.253 g/t gold from 27 metres.

Six consecutive rounds of drilling have now returned high-grade intercepts, confirming that the mineralised shoots are systematic and consistent with the resource model rather than isolated occurrences. At Mt Stirling Well, gold is hosted within narrow, flat-dipping quartz veins inside a granitoid host rock. Grade control coverage across the deposit is now complete at the spacing required for production scheduling.

The program is fully funded by BML Ventures under a 50/50 net profit sharing arrangement, while GoldArc retains 100% ownership of Mt Stirling and Mt Stirling Well.

Managing Director Paul Stephen said:

“Mt Stirling Well has returned high-grade gold in every round we have released, and this final round has delivered one of the best intercepts we have recorded there. Six rounds tell us these shoots are systematic and sitting where our model said they would be, which is exactly what you want to know before you commit to a mine plan”

GoldArc is advancing mine planning and updated mining models at Mt Stirling with BML Ventures. The company also plans to commence a reverse circulation program of approximately 6,600 metres in August 2026 to test soil gold anomalies around the Mt Stirling deposits, alongside follow-up reverse circulation drilling to test Yttria's two newly defined gold corridors for higher-grade zones at depth and along the open southern strike extent.
