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

    September 21, 2026|

    Reviewed by Joe Ashwell

    First reported on International Mining – News

    30 Second Briefing

    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.

    Technical Brief

    • System architecture is designed for mine-wide coverage over a large, topographically varied nickel operation.
    • Central control will receive real-time status from multiple dispersed water and pumping assets for alarm handling.
    • Remote monitoring reduces the need for personnel travel to high-risk pump stations and dam embankments.
    • Continuous visibility of water infrastructure supports compliance with South African mine health and safety requirements.
    • Automated alerts on abnormal levels or pump failures enable earlier intervention, limiting inundation and slope instability risk.
    • Similar brownfield restarts can use telemetry retrofits to re-establish critical water management assurance without extensive cabling.

    Our Take

    With nickel flagged as a critical mineral in several recent conference pieces in our database, the R753 million (about $46 million) restart spend at the Nkomati nickel plant in South Africa signals that operators are willing to put substantial capital into bringing idled sulphide capacity back under tighter operational control.

    Mine-wide monitoring of water and pumping systems at Nkomati is strategically important in South Africa, where water management and compliance issues have featured prominently in other regional coverage and can materially affect restart schedules and social licence for nickel operations.

    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.

    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.

    MMS at Tennant Mines’ White Devil: design and scheduling notes for planners

    Mineral Mining Services (MMS) has secured a new underground mining services contract from Tennant Mines, a subsidiary of ASX-listed Pan African Resources, at the newly established White Devil project about 50 km from Tennant Creek in Australia’s Northern Territory. The award rapidly extends MMS’s operating footprint in the Tennant Creek mineral field, positioning the contractor for further work as White Devil ramps up from initial development to full ore production. For geotechnical and mine planning teams, the contract signals imminent demand for detailed ground control, ventilation design and short-interval scheduling support on a new high-grade underground front.
