    True North Cloncurry resource update: pit and UG envelopes for mine planners

    True North Cloncurry resource update: pit and UG envelopes for mine planners

    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.

    Boliden Somincor–EDP–Greenvolt solar UPAC: integration notes for Neves‑Corvo mine engineers

    Boliden Somincor has partnered with EDP and Greenvolt to build Portugal’s largest self‑consumption solar generation unit (UPAC) near the Neves‑Corvo zinc mine at Castro Verde, supplying power directly to mine operations. The distributed solar plant will sit adjacent to one of Europe’s largest zinc orebodies, reducing grid dependence for high‑load processes such as hoisting, ventilation and paste backfill plants. For mine planners and electrical engineers, the project signals growing integration of large‑scale on‑site renewables into base‑metal underground operations in southern Europe.

    Aramine AutoNav Tele loader at Reward Gold mine: design and safety notes for planners

    RCT – Powered by Epiroc’s AutoNav Tele automation has been fitted to an Aramine L350D loader to support narrow vein stoping at Vertex Minerals’ Reward Gold mine at Hill End, after the unit was commissioned through Epiroc’s Orange Service Centre in New South Wales. The compact L350D, designed for ultra-narrow headings, is now operated via tele-remote AutoNav control rather than line-of-sight, allowing tramming and loading in constrained drives. For geotechnical and mine planners, this enables extraction in thinner ore lenses while keeping operators out of unsupported ground.

    Bosch Rexroth–MEDATech off‑highway electrification: integration notes for mine engineers

    Bosch Rexroth is partnering with MEDATech Engineering to deliver end‑to‑end electrification packages for off‑highway and mining mobile equipment, combining Rexroth’s mobile hydraulics, inverters and controls with MEDATech’s EV drivetrain integration capability. The collaboration targets full systems from componentry and software through to application‑specific design and build, aimed at OEMs and retrofit projects for haul trucks, loaders and other heavy units. For mine operators, this points to more standardised electric powertrain architectures and a clearer route to integrating high‑voltage drivetrains with existing hydraulic and control systems.
