GoldArc Confirms Systematic High-Grade Gold at Mt Stirling Well
GoldArc Resources has delivered a standout 1m at 59.9 g/t gold intercept in the final round of grade control drilling at Mt Stirling Well, reinforcing the deposit's high-grade continuity and supporting mine planning.
- Final grade control round returns 1m at 59.9 g/t Au
- Six consecutive rounds confirm systematic high-grade shoots
- ~28,785m drilled with full grade control coverage complete
- Program funded by BML Ventures under 50/50 profit share
- New ~6,600m RC drilling to test soil anomalies starts August
Final Drill Results Highlight Exceptional Grade at Mt Stirling Well
GoldArc Resources (ASX:GA8) has capped off its grade control drilling program at the Mt Stirling Well gold deposit with a remarkable 1 metre intercept grading 59.9 grams per tonne (g/t) gold. This intercept, reported from 24 metres downhole, stands as one of the highest individual grades recorded at the deposit to date, alongside multiple other intercepts exceeding 10 g/t Au. The final batch of assays, covering 50 holes and approximately 1,248 metres, confirms the presence of robust high-grade quartz-vein-hosted shoots throughout the deposit.
Consistent High-Grade Mineralisation Validates Resource Model
This sixth and concluding round of grade control drilling marks the sixth consecutive batch of results revealing strong gold grades at Mt Stirling Well, where the resource grade sits at a modest 2.3 g/t Au. The continuity of these high-grade shoots supports GoldArc’s geological model, indicating that mineralisation is not a series of isolated pockets but a systematic feature of the deposit. Managing Director Paul Stephen emphasised the significance: "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." This consistency underpins ongoing mine planning efforts in the Leonora North hub.
Extensive Drilling Program and Funding Structure
The grade control program, now complete with some 28,785 metres drilled, was fully funded by BML Ventures Pty Ltd under a 50/50 net profit sharing agreement. GoldArc retains 100% ownership of the Mt Stirling and Mt Stirling Well tenements. The drilling employed closely spaced reverse circulation (RC) methods, with fences 8 metres apart and holes approximately 6 metres apart along each fence, providing the resolution necessary for detailed mine planning and production scheduling.
Geological Distinction and Implications for Mining
Unlike the structurally complex Hydra Fault-controlled mineralisation at nearby Mt Stirling, Mt Stirling Well hosts gold within narrow, flat-dipping quartz veins embedded in granitoid host rock. This distinct geological setting has been systematically tested, with the latest results confirming near-surface high-grade mineralisation consistent with previous resource estimates. Such precise grade control data reduces dilution risk and enhances extraction optimisation ahead of potential open-pit mining.
Upcoming Drilling and Exploration Plans
Looking ahead, GoldArc plans to commence a ~6,600 metre RC drilling program in August 2026 targeting soil gold anomalies surrounding the Mt Stirling deposits. This next phase aims to expand the footprint of known mineralisation and test for higher-grade zones at depth and along strike. The company is also following up on newly defined gold corridors at its Yttria prospect, seeking to uncover additional high-grade targets.
Bottom Line?
GoldArc’s final grade control results at Mt Stirling Well reinforce the deposit’s high-grade continuity and provide a solid foundation for advancing mine planning and future drilling campaigns.
Questions in the middle?
- Will the upcoming 6,600m RC program extend the high-grade footprint beyond Mt Stirling Well?
- How will these consistent grade control results influence the timing and scale of mine development?
- Could further drilling at Yttria reveal economically significant gold corridors complementary to Mt Stirling?
