GoldArc Resources (ASX:GA8) reports final Mt Stirling Well grade control results
GoldArc Resources has reported the 6th and final round of grade control results from the Mt Stirling Well deposit (M37/1305), part of the partner funded reverse circulation (RC) grade control program in the Leonora North hub.
The final round delivered 1m @ 59.9 g/t Au from 24m (26BSWRC973), together with further high grade intercepts reported from Mt Stirling Well.
Highlights
Final grade control results from Mt Stirling Well delivered 1m @ 59.9 g/t Au from 24m (26BSWRC973).
Additional intercepts included 1m @ 32.7 g/t Au from 30m (26BSWRC977), 3m @ 14.253 g/t Au from 27m including 1m @ 32.4 g/t Au from 28m (26BSWRC975), 1m @ 31.5 g/t Au from 29m (26BSWRC976), and 1m @ 25.3 g/t Au from 27m (26BSWRC954).
Six consecutive rounds have returned high grade intercepts, with the company reporting that high grade mineralisation recurs across the drilled area and is not limited to a single isolated intercept.
Approximately 28,785m of the combined program has now been drilled, with grade control coverage at Mt Stirling Well complete and mine planning advancing at Mt Stirling.
The Mt Stirling Well deposit is located approximately 700m southwest of Mt Stirling within the Leonora North hub and hosts a JORC Inferred Mineral Resource of 198,000t @ 2.3 g/t Au for 15,000oz.
The final release reports a further 50 holes for approximately 1,248m, covering assay submission batches 35, 36 and 37.
The latest results included one of the strongest individual intercepts recorded at the deposit, 1m @ 59.9 g/t Au from 24m, alongside 7 further intercepts above 10 g/t Au, with GoldArc reporting high grade quartz vein hosted shoots across the deposit.
At Mt Stirling Well, gold mineralisation occurs within narrow, flat dipping quartz veins within a granitoid host rock, a different structural setting to the Hydra Fault controlled schistose mylonitic mineralisation at Mt Stirling.
The company reported that the final round of grade control results continue to confirm near surface, high grade mineralisation consistent with the resource model.
The grade control programme employs a closely spaced drill grid, with fences 8m apart and holes approximately 6m apart along fences, to define ore grade boundaries at the resolution required for production scheduling.
The program assists BML Ventures with extraction scenarios, dilution risk and production scheduling for each blast zone.
GoldArc 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”.
The grade control program is funded 100% by BML Ventures Pty Ltd under a 50/50 net profit sharing arrangement, while GoldArc retains 100% ownership of Mt Stirling (M37/1306) and Mt Stirling Well (M37/1305).
GoldArc is a Western Australian focused mineral exploration company with a portfolio of gold projects located in the Leonora and Kookynie districts of the Eastern Goldfields.
The company reports a total JORC Mineral Resource of 200,014oz across its projects.
The company is advancing near term milestones including mine planning and updated mining models at Mt Stirling with BML Ventures, a ~6,600m RC program in August 2026 testing soil gold anomalies around the Mt Stirling deposits, and follow up RC drilling at Yttria’s 2 newly defined gold corridors.
