Seven refineries, one outcome

New Caledonia and Australia hold the West's largest concentration of nickel refining assets. Every one has cut capacity, gone idle, or required public capital.

  1. 01

    Koniambo

    New Caledonia

    Closed

    Glencore exited its 49% stake in 2024. SMSP could not carry operations alone and closed the site, laying off 1,200 staff and stranding a $9B asset.

    Smelting → 21% ferronickel

    60,000 t/yr
    Actual
    ~50% for five years
  2. 02

    Doniambo

    New Caledonia

    State life support

    No profit since the $3B modernization in 2013. Eramet and SLN burned more than $200M a year from 2020 to 2026. A zero-interest state loan in January 2026 buys time while ownership is reassessed.

    Route
    Smelting → 21% ferronickel
    Nameplate
    56,000 t/yr
    Actual
    ~40% for five years
  3. 03

    Prony Resources

    New Caledonia

    Commissioning delays

    Bought the mothballed Vale Goro assets for $1.1B and underwrote $590M of debt against a Tesla offtake. Design flaws in on-site acid production and a major tailings leak have kept it unprofitable, despite a $45M/yr French energy subsidy.

    Route
    HPAL → 38% nickel hydroxide cake
    Nameplate
    42,000 t/yr offtake
    Actual
    Below plan
  4. 04

    Murrin Murrin

    Western Australia

    Throttled

    Revenue fell 40% since 2022, from $1.11B to $560M. Declared a $475M tax impairment in 2026, lowering assets value close to $0.

    Route
    HPAL → 38% MHP
    Nameplate
    40,000 t/yr
    Actual
    Cut to 30,000 t/yr
  5. 05

    Kalgoorlie

    Western Australia

    Mothballed

    BHP spent over $3B modernizing between 2020 and 2024, plus more than $450M a year to keep it running, then shut it with the rest of Nickel West pending a 2027 review.

    Route
    Flash smelting → 68% matte

    Idle since 2024

    Kwinana

    Western Australia

    Mothballed

    Commissioned in 2021 as Australia's first battery-grade nickel sulfate plant. It never scaled past pilot volumes before closing in 2024.

    Route
    Refining → battery-grade NiSO₄
    Nameplate
    Class I sulfate
    Actual
    Commercial volumes never achieved

    Yabulu

    Queensland

    Idle since 2016

    Purchased by Clive Palmer in 2014 and idle for a decade, with no buyer found and the original developers tied up in an embezzlement case.

    Route
    HPAL + ammoniacal SX → 38% MHP
