    Grecian Magnesite’s Aramine L440B at Koutzi: ventilation and fleet notes for engineers

    Grecian Magnesite’s Aramine L440B at Koutzi: ventilation and fleet notes for engineers

    First reported on International Mining – News

    30 Second Briefing

    Grecian Magnesite is adding a fully electric, battery-powered Aramine L440B loader to its Koutzi underground magnesite mine in Evia, Greece, to help ramp towards the site’s ~50,000 t/y design capacity of pre-concentrated ore. The new L440B will work alongside an existing Aramine L140B, expanding the battery LHD fleet for production and development headings without increasing diesel equipment underground. For mine planners and ventilation engineers, the move signals continued adoption of battery loaders to cut heat and diesel particulates while sustaining output in confined workings.

    Technical Brief

    • Battery-electric drivetrain removes local exhaust heat load, directly reducing ventilation air quantity requirements per heading.
    • Zero diesel particulates at the loader face simplifies compliance with underground occupational exposure limits.
    • Reduced heat and fumes at the face allow longer operator exposure times before reaching thermal comfort limits.
    • Lower ventilation demand can defer or downsize fan and duct upgrades as production approaches design throughput.
    • Charging infrastructure for multiple battery LHDs concentrates power demand at fixed bays instead of distributed fuel bays.
    • Similar small- to mid-scale underground industrial mineral mines can replicate battery LHD deployment without full-fleet electrification.

    Our Take

    Magnesite appears in only a handful of keyword-matched pieces in our database, so Grecian Magnesite’s move at Koutzi in Evia stands out compared with the far more common copper, gold and battery-metals electrification case studies.

    Battery-electric equipment such as Aramine’s loader at a Greek underground magnesite operation is likely to be watched by other industrial mineral mines in Europe, where tightening air-quality and CO₂ rules can make diesel-free fleets a permitting and ESG advantage.

    For a commodity like magnesite, which feeds into refractories and other energy-intensive downstream uses, decarbonising mine operations at sites such as Koutzi gives producers an extra lever when marketing ‘lower-footprint’ material to EU industrial customers under emerging carbon-border and supply-chain reporting regimes.

    Scope Systems cyber attack: resilience and risk lessons for mining IT teams

    A ransomware attack on Perth-based Scope Systems’ Pronto Xi ERP cloud stack disrupted dozens of mining customers, including Northern Star Resources and Evolution Mining, in what MM‑ISAC’s Rob Labbe calls the broadest single third‑party cyber event the sector has seen. Scope says client servers were restored from backups and not directly accessed, but admits internal data was exfiltrated and has not disclosed the attack vector, raising questions about visibility at hypervisor, storage and backup layers. The incident spotlights how multi‑tenant vCenter/ESXi environments, VM cloning and snapshot abuse—already used by groups like Akira—could expose integrated exploration, production and maintenance data across more than 400 Pronto Xi‑reliant mining operations.

    Newmont’s Red Chris underground expansion: block cave design and capex notes for engineers

    Newmont’s Red Chris mine in British Columbia has secured an amended Environmental Assessment Certificate and Mines Act permit, allowing a shift from open-pit to underground block caving and extending operations into the mid-2040s. The copper-gold porphyry deposit in the Golden Triangle hosts an estimated 20 million oz of gold and 13 billion lb of copper, with the block cave expected to lift Canada’s copper output by about 15%. The project entails several billion dollars in capital, around 1,800 construction jobs and roughly 1,500 operating roles at peak.

    Goldman cuts gold price forecast to US$4,900: planning notes for mine projects

    Goldman Sachs has cut its end‑2026 gold price forecast by US$500/oz to US$4,900/oz after the US Federal Reserve, under new chair Kevin Warsh, signalled a hawkish shift that has pushed market-implied December rate hike odds to 87%. Spot gold has already fallen to about US$4,100/oz, down 27% from its near‑US$5,600/oz January peak, with three consecutive monthly losses between March and May and a 4% year‑to‑date decline. Goldman warns a 2026 year‑end target as low as US$4,400/oz is possible if rates rise, partly offset by ongoing central‑bank buying of roughly 50 tonnes/month this year and 40 tonnes/month next year.
