Highlights

  • RC drilling at Yellow Jack confirmed shallow, continuous oxide gold from surface to approximately 50 metres depth.
  • Great Divide Mining has formally lodged statutory mining lease applications and environmental authority approvals.
  • Devils Mountain hosts high-grade gold-antimony targets providing critical defence mineral exposure.
  • GDM maintains a tightly held capital structure with strong director and founder alignment.

Great Divide Mining (ASX:GDM) is pressing hard toward production — mining lease applications are filed, environmental approvals are in progress, and heap leach metallurgy is under evaluation at Yellow Jack, a shallow oxide gold project in North Queensland where drilling has confirmed continuous grade from the surface down.

Yellow Jack: Validation from the Surface Down

Extensive reverse circulation drilling at the Yellow Jack Gold Project in the Georgetown Inlier of North Queensland has validated shallow, continuous gold mineralisation extending from surface to approximately 50 metres depth. Assay results consistently verified robust oxide grades, demonstrating that the ore body remains completely open along strike and down dip.

GDM has formally advanced statutory mining lease applications, environmental authority approvals, and baseline site infrastructure planning, establishing a direct trajectory toward maiden commercial gold production. The project's historical mining heritage and favourable shallow depth profile support a low-cost open-pit extraction scenario.

Heap Leach Economics and Metallurgical Work

Management is completing comprehensive metallurgical leach recovery column testing to finalise processing plant flowsheets, reagent consumption profiles, and operational water balancing. Heap leach extraction significantly lowers initial capital expenditure thresholds, enabling junior operators to achieve rapid commercial payback during periods of elevated Australian-dollar gold pricing.

Regional exploration drilling across the surrounding tenure aims to expand the resource base. Proving up satellite oxide gold deposits within trucking distance of Yellow Jack would extend the project lifecycle and increase annual production throughput.

Antimony at Devils Mountain Adds Critical Mineral Exposure

Beyond Yellow Jack, GDM holds the Devils Mountain project, which hosts high-grade gold-antimony targets. Antimony is a critical defence and industrial metal experiencing intense global supply tension following international export restrictions, making this a strategically timely asset to hold.

At Cape River, historical alluvial and hard-rock workings indicate widespread gold anomalism that remains largely untested by modern systematic geophysics and deep drilling, providing long-term exploration upside beyond the near-term Yellow Jack production focus.

Capital Structure and Execution Risks

GDM shares traded at $0.280 on 2 October 2026, with a market capitalisation of $19.45 million — a net change of 8.20% over 12 months. The company maintains a tightly held capital structure with substantial director and founder alignment, enhancing share price leverage upon positive operational catalysts.

Regulatory permitting in Queensland requires rigorous compliance with environmental protection standards, cultural heritage clearances, and rehabilitation bonding. Unforeseen delays in securing formal mining lease grants could extend production timetables. GDM also remains exposed to diesel and skilled labour inflation, contractor availability, and international gold price fluctuations.
