GoldArc Resources (ASX:GA8) broad high-grade intercepts confirm deposit-wide continuity at Mt Stirling

GoldArc Resources has reported the fifth batch of assay results from its partner-funded reverse circulation (RC) grade control program at the Mt Stirling gold deposit in the Leonora district of Western Australia.

The batch covers 68 holes for 2,098m of drilling in the eastern sector, returning broad, high-grade intercepts, including intervals exceeding the Indicated Mineral Resource grade of 2.1g/t Au.

The results confirm the continuity of the ore envelope across the eastern sector and provide a critical dataset for mine planning under the 34,000m program funded by BML Ventures Pty Ltd (BMLV) under a 50/50 net profit share arrangement, with GoldArc retaining 100% ownership of Mt Stirling (M37/1306) .

Highlights:

• 68 RC holes for 2,098m returned broad high-grade intercepts including 17m @ 3.48g/t Au and 20m @ 1.85g/t Au with internal high-grade zones up to 13.00g/t Au .
• Ten intercepts of 7m or greater above 1.38g/t Au confirm a wide, consistent ore envelope across the eastern sector .
• Narrow, high-grade shoots continue alongside the broader envelope, including 2m @ 26.10g/t Au, demonstrating structural continuity from prior batches .
• Approximately 19,180m of the 34,000m RC program has now been completed, representing over 56% of the total program .
• Grade control results will feed directly into mine planning and selective mining studies, supporting potential open-pit development under the BMLV arrangement .

Eastern sector drilling demonstrates the persistence of high-grade mineralisation within a broad ore envelope, hosted in high-strain schistose-mylonitic rocks along the Hydra Fault within strongly hydrothermally altered meta-basalt.

Gold is concentrated within silicified, sulphidic intervals with elevated arsenic content, and grade control data confirms both lateral and vertical continuity, which is critical for pit design, selective mining, and extraction optimisation.

The program uses a closely spaced drill grid to provide high-resolution data for production scheduling, with samples prepared and assayed by Bureau Veritas under QAQC protocols, ensuring analytical reliability.

GoldArc Managing Director Paul Stephen said:

“These results continue to build a clear picture of the Mt Stirling ore body. The broad intercepts we’re seeing across the eastern sector are consistent with the grade and width we’ve observed across the north-western and central sectors in prior batches. That consistency across the full deposit footprint is encouraging and will assist our ongoing mine planning work with BML Ventures,”

The program demonstrates systematic lateral continuity of mineralisation across Mt Stirling, reinforcing the deposit’s potential for structured open-pit extraction.

With over half of the grade control drilling completed, GoldArc is positioned to integrate these data into a robust mine plan and selective mining framework.

The continuity and high-grade nature of the ore envelope provide confidence in operational planning and underpin further exploration and resource development within the Leonora North tenure.
