    Larvotto’s new Hillgrove production milestone: flotation and offtake notes for engineers

    First reported on Australian Mining

    30 Second Briefing

    Larvotto Resources has produced the first antimony and gold concentrate from the redeveloped Hillgrove mine in New South Wales, following the August restart of processing operations. The milestone comes after completion of a plant upgrade programme that brought new flotation cells and concentrate filter presses online to handle antimony–gold ore. Commissioning progress towards steady-state production signals renewed sulphide flotation capacity at a site historically known for complex refractory mineralogy, with implications for concentrate quality and downstream smelting contracts.

    Technical Brief

    • Concentrate filter presses have been brought online to dewater antimony–gold concentrates for transport and smelting.
    • Early concentrate production provides metallurgical performance data to refine reagent schemes and flotation operating parameters.
    • For similar brownfield sulphide projects, phased recommissioning of legacy flotation circuits reduces capex and ramp-up risk.

    Our Take

    The earlier restart plan for Hillgrove in New South Wales targeted 4,900 t/y antimony and 40,500 oz/y gold over eight years, so hitting new production milestones likely underpins Larvotto Resources’ ability to market Hillgrove as a reliable gold–antimony supplier in offtake or financing discussions.

    Hillgrove’s antimony output positions Larvotto within the small cluster of critical-mineral stories in our mining database, which tend to attract more scrutiny on processing, environmental performance and downstream refining options than pure gold plays in Australia.

    Larvotto’s parallel push into copper around Mt Isa via the Blockade mine and the proposed Hammer Metals acquisition suggests Hillgrove’s performance could become a cash-flow anchor that supports higher-risk copper exploration and development activity in Queensland.

    Sandvik’s Toro electrification strategy: design and power notes for mine engineers

    Sandvik used its Future of Mining 2026 event in Turku to set a new underground electrification strategy built around a “Toro standard” for its battery-electric load and haul fleet. Head of BEV Strategy Tommi Valkonen outlined plans to unify battery systems and controls across Toro-branded loaders and trucks, targeting faster battery swaps and simplified maintenance compared with today’s mixed platforms. The strategy signals tighter integration of BEV hardware, software and charging, with implications for mine power design, fleet standardisation and lifecycle cost modelling.

    Omniflex at Nkomati nickel plant: mine-wide water monitoring lessons for engineers

    Omniflex is installing a new wireless telemetry system across the Nkomati nickel plant in South Africa to restore mine-wide monitoring of water and pumping infrastructure as the operation restarts after a R753 million ($46 million) investment. The system replaces legacy Omniflex equipment supplied under previous ownerships and is expected to give centralised visibility of dam levels, boreholes and pump stations over the entire site. For engineers, the upgrade signals renewed focus on remote supervision of dewatering and process water balance ahead of ramp-up.

    Liebherr Western Australia training centre: safety and productivity notes for mines

    Liebherr-Australia has opened a new mining training centre in Perth, Western Australia, built around an administrative hub with three dedicated training rooms housing three machine simulators, including a T 264 haul truck unit. The facility is designed for advanced, technology-enabled training for mine operators, maintenance personnel and Liebherr support teams from sites across Australia. For mines running large Liebherr truck and excavator fleets, the centre enables off-site operator upskilling, scenario-based training and reduced in-pit onboarding time.
