True North Cloncurry resource update: pit and UG envelopes for mine planners
Reviewed by Tom Sullivan

First reported on Australian Mining
30 Second Briefing
Exploration activity is accelerating across Australia, with recent campaigns reporting high-grade intercepts in gold, tungsten and critical minerals and several new drill targets defined from geophysics and geochemistry. True North Copper has updated its resource at Cloncurry in Queensland, refining copper and gold tonnages and grades across multiple lodes and signalling scope for further step-out drilling. For geotechs and mine planners, the work points to expanding pit and underground envelopes in established districts rather than purely greenfield growth.
Technical Brief
- For similar brownfield mining assets, such iterative resource tightening typically precedes staged pit push-backs and deeper underground access.
Our Take
Gold-linked content is one of the denser clusters in our 1024 Mining stories, and pairing it with tungsten and other critical minerals in Australia tends to flag projects that could straddle both precious and strategic supply chains rather than pure-play gold exploration.
In our database, Australian critical minerals coverage is increasingly juxtaposed with stories like Albemarle’s Kemerton lithium hydroxide care-and-maintenance move (12 Feb 2026), which signals that multi-commodity explorers with gold and tungsten exposure may be better insulated from single-commodity price or demand shocks.
Given tungsten’s classification as a critical mineral and its appearance alongside gold in 340 keyword-matched pieces, exploration updates in regions like Australia often have permitting and funding angles that differ from conventional gold-only projects, particularly where governments are seeking to de-risk strategic supply.
