True North legacy mine funding and peers: exploration takeaways for project teams
Reviewed by Tom Sullivan

First reported on Australian Mining
30 Second Briefing
True North Copper has secured $5 million in Queensland Government funding to restart exploration at the legacy Cloncurry copper project, targeting extensions to historical high-grade lodes using modern geophysics and deeper diamond drilling. Aureka is ramping up RC and diamond drilling across its Western Australian gold tenements, focusing on structurally controlled shear-hosted mineralisation near existing 1–2Mtpa processing hubs to fast-track potential toll treatment. Rincon is expanding silver and base metal exploration in South Australia with step-out drilling around known vein systems and updated 3D geological modelling to refine resource targets.
Technical Brief
- Integration of modern geophysics with historical datasets across all three companies is intended to tighten structural interpretations before committing to resource-definition drilling.
- Collectively, these programmes show explorers designing drilling strategies around existing processing hubs and legacy infrastructure to compress potential development timelines and capital intensity.
Our Take
True North Copper’s focus on copper–gold–silver in Australia sits within a large cluster of our 1106 Mining stories where polymetallic copper projects are being positioned as both energy-transition and bullion plays, which can help legacy assets attract non-traditional funding pools.
The funding for a legacy copper–gold asset in Australia comes as our coverage shows gold producers benefiting from a 40% bullion price surge in 2025, suggesting improved economics for brownfield gold-linked projects that can demonstrate quick resource conversion or restart timelines.
With copper and silver both flagged as key commodities in the Fraser Institute’s 2025 investment survey coverage, Australian legacy copper–silver assets like those targeted by True North Copper may gain comparative appeal versus greenfield critical-mineral projects that face longer permitting and infrastructure lead times.
