    Liebherr’s new machines for Northern Star: planning and stability notes for engineers

    First reported on Australian Mining

    30 Second Briefing

    Liebherr-Australia has commissioned eight new machines for Northern Star Resources across the Kalgoorlie Super Pit and another Western Australian operation, adding to an existing fleet of five Liebherr units on site. The deployment includes PR 776 mining dozers working on the Super Pit’s ultra-large open-cut benches, where high wall stability, floor control and push efficiency are critical for maintaining ore feed to the Fimiston processing plant. For geotechnical and mine planners, the expanded dozer fleet signals higher capacity for cutback development, dump shaping and haul road maintenance under tight production schedules.

    Technical Brief

    • Hydrostatic drive allows continuous variable speed control, improving push efficiency on variable-grade waste and ore.
    • High blade capacity and drawbar pull support rapid bulk rehandle for cutback advance and dump crest shaping.
    • Modern cab ergonomics and visibility aid precise floor trimming, reducing dozer-induced roughness affecting haul truck tyre life.
    • Factory-integrated machine health monitoring supports condition-based maintenance scheduling under high utilisation mining duty.
    • Compatibility with high-precision GPS grade control enables tighter bench geometry and ramp width compliance.

    Our Take

    Liebherr-Australia’s record bucket output in 2025, as reported in our coverage of its Adelaide fabrication facility, suggests the OEM has the local manufacturing depth to support fleet expansions like Northern Star Resources’ new machines at the Kalgoorlie super pit without long lead times.

    Within our mining project and product coverage, Western Australia frequently appears as a testbed for high-capacity mobile fleets, so this incremental build-out of Liebherr equipment at Kalgoorlie is likely to influence future standardisation and support arrangements across Northern Star’s other operations in the state.

    The step-up from an existing five Liebherr units to a larger fleet spread over two WA operations signals a maturing lifecycle-support relationship, which typically brings more structured condition monitoring and rebuild planning rather than purely transactional equipment supply.

    From reactive to predictive mining safety: data and sensing priorities for engineers

    Mining safety specialist David Coghlan, head of technology and product at TURCK, argues that connected sensing and control must shift mines from reactive alarms to predictive intervention as fleets, conveyors and fixed plant become more automated. He points to integrated proximity detection, real-time location and condition monitoring on mobile equipment, tied into site-wide networks, as the basis for predicting collision and entrapment risks rather than just logging incidents. For geotechnical and operations teams, this means designing safety systems around data quality, latency and interoperability, not just compliance with existing guarding and lock-out procedures.

    Evolution becomes Carnaby’s largest shareholder: M&A and project signals for mine planners

    Evolution Mining has become Carnaby Resources’ largest shareholder with a 13.7 per cent stake after acquiring the QIC Queensland Critical Minerals Fund’s ~37.9 million Carnaby shares as part of its proposed $213 million takeover. Evolution also issued about 2.6 million new shares to QIC, signalling continued use of scrip-based structures in Australian mid-tier M&A. For copper–gold project developers, the move points to stronger strategic interest from established producers in advanced exploration portfolios rather than greenfield assets.

    Develop’s Woodlawn drilling: 15-year mine life implications for planners and geotechs

    Develop Global’s latest underground drilling at the Woodlawn copper–zinc mine in New South Wales has returned intercepts grading up to 15.7 per cent copper equivalent (CuEq), supporting its Project DM15 plan to extend mine life from 10 to 15 years. The high-grade results, from step-out holes targeting depth extensions of existing lenses, suggest additional sulphide resources beyond the current reserve envelope. For mine planners and geotechs, this points to a longer stoping schedule, potential redesign of sequencing and backfill, and extended use of existing underground infrastructure.
