GoldArc Scores 106g/t Au Hit in Mt Stirling Grade Control Drilling

Record High-Grade Intercept Boosts Mt Stirling Prospects

GoldArc Resources (ASX:GA8) has delivered a striking 1 metre intercept grading 106 grams per tonne (g/t) gold from 8 metres depth in the latest batch of its partner-funded grade control drilling at the Mt Stirling deposit in Western Australia. This intercept is the highest individual grade recorded in the ongoing 34,000-metre Reverse Circulation (RC) drilling program, underscoring the presence of very high-grade gold shoots within the deposit's interpreted structural framework.

The 141-hole batch covering 4,021 metres includes several other standout intercepts, such as 3m at 5.99g/t Au (including 1m at 14.00g/t) and 2m at 7.00g/t Au (including 1m at 13.50g/t), alongside broader lower-grade zones extending up to 18 metres. These results collectively confirm the lateral continuity of mineralisation across Mt Stirling's eastern and shallow infill sectors, providing critical data for refining mine planning.

Partner-Funded Program Advances Without Capital Outlay

The drilling campaign, fully funded by BML Ventures Pty Ltd under a 50/50 net profit share agreement, has now surpassed the halfway mark with approximately 17,080 metres completed. GoldArc retains 100% ownership of Mt Stirling, with the partner funding removing upfront capital requirements for the company. Managing Director Paul Stephen highlighted that every metre drilled brings the project closer to a detailed mine plan, emphasizing the importance of the high-grade shoots within a consistent mineralised envelope.

This program is a continuation of the company’s systematic approach to de-risking Mt Stirling, following earlier rounds of drilling that demonstrated high-grade continuity in the central sector. The current results build on that foundation, reinforcing the structural control by the Hydra Fault and supporting optimisation of extraction to maximise gold recovery and minimise dilution.

Grade Control Drilling to Support Open-Pit Development

The closely spaced drill grid, with fences 8 metres apart and holes approximately 6 metres apart along them, is designed to provide the resolution necessary for production scheduling. The grade control data will directly inform the mine plan, which is advancing towards potential open-pit development under the BML Ventures partnership.

Samples are processed under a rigorous QAQC protocol at Bureau Veritas in Kalgoorlie, ensuring the reliability of assay data. The geological context indicates gold is associated with hydrothermally altered meta-basalt within the Hydra Fault zone, with mineralisation characterised by silicified and sulphidic intervals enriched in arsenic.

Ongoing Assay Results to Maintain News Flow

Further assay batches are in progress, with results to be released progressively following quality validation and geological review. This steady cadence of data is expected to sustain market interest as the company moves closer to finalising a robust mine plan.

GoldArc’s approach aligns with its broader strategy of growing its resource base and advancing projects through partner-funded drilling, as demonstrated by previous initiatives at Leonora North and South. The current drilling at Mt Stirling complements these efforts, with the company having recently secured full ownership of the deposit and executed agreements to support development funding.

These developments come on the back of the company’s aggressive exploration and development campaign, including a recent high-grade continuity at Mt Stirling confirmation and a fully funded drilling and ownership milestone earlier this year. Investors will be keen to track how the remaining assay batches shape the overall grade profile and resource model.
