    MACA’s first Liebherr dozers at Duketon: fleet strategy notes for mine planners

    First reported on International Mining – News

    30 Second Briefing

    Liebherr-Australia has delivered three PR 776 G8 dozers to MACA, a Thiess company, for deployment at Regis Resources’ Duketon gold project in Western Australia, marking the first Liebherr dozers in MACA’s mining fleet. The PR 776 G8 is a 70‑t class mining dozer typically used for bulk push, stockpile management and haul-road maintenance, giving MACA an alternative to its existing Caterpillar and Komatsu-heavy fleets. Liebherr-Australia is scheduled to supply two R 9300 mining excavators later this year, signalling deeper standardisation on Liebherr primary loading and dozing assets at Duketon.

    Technical Brief

    • Blade and ripper configurations can be tailored for bulk push versus rehabilitation, enabling flexible deployment across pits.
    • Fuel‑efficient engine and idle management systems target lower unit costs versus conventional powershift dozers in similar class.
    • Cab design with integrated monitoring and assist systems supports operator visibility on stockpiles and dump edges.
    • Standardising on Liebherr loading and dozing assets at a single site simplifies spares, tooling and OEM service interfaces.
    • For other contract miners, mixed‑OEM fleets at single operations can de‑risk supply chain and pricing exposure.

    Our Take

    Liebherr-Australia’s record excavator bucket output in Adelaide in 2025, highlighted in our recent coverage, suggests the supplier has the local manufacturing depth to support MACA’s new PR 776 G8 dozers and upcoming R 9300 excavators over the full life of the Duketon gold project fleet.

    MACA’s equipment move at the Duketon gold project comes as it is also involved in an autonomous haulage system trial with Thiess at Norton Gold Fields’ Mulgarrie operation, signalling that the contractor is simultaneously upgrading both its conventional and autonomy-ready fleets in Western Australian gold.

    Within our 1204 Mining stories, Liebherr-Australia appears increasingly in Western Australian gold fleet renewals (e.g. recent deliveries to Northern Star Resources), so the MACA deployment at Duketon reinforces Liebherr’s growing presence in contractor-operated gold operations rather than just owner-operator mines.

    Techking–Boonray autonomous mining tyres: design and duty-cycle notes for engineers

    Techking is collaborating with Chinese autonomous haulage specialist Boonray to co-develop mining truck tyres tailored to electric and driverless fleets, where high, instantaneous torque and tighter speed control change loading behaviour. The partners are integrating tyre design into early vehicle engineering, using Boonray’s AHS control data on torque curves, duty cycles and haul-road conditions to refine carcass structure, compound selection and heat management. For mine operators, this points to tyre performance being tuned to specific autonomous truck–road systems rather than generic TKPH-based selection.

    EcoPower Mate temporary power: layout and staging insights for mine planners

    EcoPower Mate introduces a modular temporary power system for remote mines, targeting exploration camps, mobile offices, communications nodes and construction facilities that currently rely on diesel gensets. Designed for locations with shifting footprints and variable loads, the units can be redeployed as drilling pads, laydown areas or satellite camps move, reducing the need to oversize fixed generator banks. For mine planners and project engineers, the approach supports more flexible power layouts and staged infrastructure without committing to early grid extensions.

    Sedgman wins Barroso lithium FEED: design and risk notes for project engineers

    Sedgman has secured the Front-End Engineering and Design contract for the lithium concentrator plant at Savannah Resources’ Barroso lithium project in northern Portugal, following its earlier work on the process flowsheet and Definitive Feasibility Study plant design. The FEED scope will refine equipment selection, layout and mass–energy balances for the hard-rock spodumene concentrator, de-risking capital estimates ahead of a final investment decision. For geotechnical and civil teams, the move signals progression towards detailed earthworks, foundations and tailings/waste infrastructure design on what is billed as mainland Europe’s largest lithium project.
