    Cyclone Narelle hits Australia: logistics and safety lessons for mine operators

    Cyclone Narelle hits Australia: logistics and safety lessons for mine operators

    First reported on MINING.com

    30 Second Briefing

    Tropical Cyclone Narelle, peaking at category 4 near Exmouth with forecast gusts to 165 km/h and heavy rainfall, has forced port closures at Ashburton, Cape Preston West, Dampier, Varanus Island and Geraldton, disrupting iron ore and LNG export logistics across Western Australia. Rio Tinto suspended port operations while maintaining mining and rail, Mineral Resources halted marine operations at Ashburton under its cyclone plan, and Fenix Resources scaled back non-essential mining and haulage amid diesel shortages linked to Middle East supply constraints. Westgold and Ramelius prepared for significant rainfall around Mount Magnet, with Ramelius planning short-term fuel sourcing from Perth instead of Geraldton.

    Technical Brief

    • Bureau of Meteorology guidance specified sustained winds near 120 km/h and gusts up to 165 km/h.
    • Narelle was downgraded from category 4 offshore Exmouth to category 3 by Friday afternoon, then forecast category 2.
    • Pilbara Ports implemented staged berth clearing at Ashburton, Cape Preston West, Dampier and Varanus Island from Tuesday night.
    • Mineral Resources activated a formal cyclone management plan, including full suspension of marine operations at Port of Ashburton.
    • Fenix Resources explicitly linked operational curtailment to compounded diesel shortages from Middle East conflict and cyclone-related logistics.
    • Ramelius’ Mount Magnet preparations followed a standardised severe weather protocol focused on significant rainfall rather than direct wind impact.
    • Narelle’s four Australian landfalls in one week illustrate multi-region contingency planning needs for fuel, ports and workforce movements.

    Our Take

    Pilbara Ports’ recent record throughputs of 71.2 Mt in December 2025 and 55.9 Mt in February 2026 mean even short cyclone-related closures at Port Hedland and Dampier can quickly translate into noticeable volatility in iron ore export schedules for BHP, Rio Tinto and Fortescue.

    Trump ‘a gold person’: price spike and safe‑haven signals for mine planners

    Gold prices jumped up to 3% to more than US$4,550/oz on Friday, heading for their first weekly gain since the Iran conflict began, after weeks of war-driven volatility and earlier price weakness. During his first Cabinet meeting since the US strike on Iran over three weeks ago, President Donald Trump called himself “a gold person” and backed the metal as “real stuff” that “you can’t imitate”, reinforcing bullion’s safe-haven narrative. A federal arts commission has also approved a 24‑karat commemorative coin design bearing Trump’s face for the US 250th anniversary.

    AngloGold’s 4.9Moz Nevada project: economics and capex lens for mine planners

    AngloGold Ashanti has completed a pre-feasibility study for its Arthur project in Nevada’s Beatty district, confirming 4.9 million oz of gold reserves across the Silicon and Merlin deposits and outlining an initial nine-year mine life with average output of 500,000 oz/y. More than 95% of mineralisation is oxide, suited to bulk mining and conventional processing, with all-in sustaining costs estimated at $954/oz and initial capex at $3.6 billion. Using a $1,950/oz base case, AngloGold reports after-tax NPV (5%) rising from $1.7 billion at $2,715/oz to $3.4 billion at $3,500/oz, with feasibility work starting June alongside environmental and hydrological baseline studies.

    Paragon BC PhotonAssay–Veracio lab: near-real-time geochem for drill planning

    Paragon Advanced Labs has launched a British Columbia laboratory that combines Chrysos PhotonAssay™ with Veracio’s rapid, non-destructive core scanning to deliver near-real-time whole-rock geochemistry. The service targets BC’s tight exploration windows and assay backlogs by generating gold and multi-element data quickly enough for decisions while drilling is still under way. For geologists and drill planners, this enables dynamic hole steering, earlier vectoring towards mineralised structures, and reduced reliance on delayed conventional fire-assay workflows.
