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

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.
