    Collahuasi permit setback: desalination and water-supply risks for mine planners

    A Chilean environmental court has annulled the permit for Collahuasi’s $3.2 billion desalination plant, forcing a reassessment of the seawater system that pumps desalinated water nearly 200 km from the Pacific coast to the 4,600‑metre‑elevation mine, which produced over 404,000 tonnes of copper in 2025. The decision affects an expansion intended to add 20 years of mine life and cut reliance on continental water, even though contractor Techint completed the pumping system in April. Industry leaders, including Chilean Mining Chamber president Manuel Viera, cite the case as evidence of a “cursed” regime where a single project can need 500+ permits, raising schedule and cost risk for large‑scale desalination and water‑supply infrastructure.

    BHP rare earths assessment at Olympic Dam: project and water risks for engineers

    BHP must, under a revised 78‑page Olympic Dam indenture agreement tabled in the South Australian parliament, assess within two years whether rare earths and other critical or strategic minerals such as neodymium and praseodymium can be commercially recovered from current waste streams. If BHP deems extraction technically or economically unviable, third parties must be given an opportunity to commercialise these minerals, while the framework also enables consideration of a A$4 billion copper refinery expansion and up to A$12.7 billion in further mine and concentrator upgrades by 2032. The pact additionally requires BHP to submit by May 2031 a plan to cease Great Artesian Basin groundwater extraction by May 2036, with a Port Augusta seawater desalination scheme being advanced to support a potential lift in South Australian copper output towards 650,000 tonnes per year by the mid‑2030s.

    Marimaca Copper acid plant acquisition: project economics and supply risk lens

    Marimaca Copper is insulating its $587 million Marimaca oxide heap-leach project in northern Chile from sulphuric acid price spikes by buying and planning to relocate the second-hand Dos Amigos acid plant from Mejillones, 25 km away, acquired for $2.5 million versus an estimated $50–70 million for a new installation. The 13-year SX-EW operation is designed to produce 50,000 t/y of copper cathode from 178.6 Mt at 0.42% Cu, with a post-tax NPV of $709 million and 31% IRR at $4.30/lb. Parallel drilling at the nearby Pampa Medina target is returning long sulphide intercepts such as 424 m at 0.58% Cu and 2.2 g/t Ag from 424 m, indicating stacked oxide–sulphide potential beyond the starter oxide phase.

    MaxMine machine learning at Australian mine sites: haulage data lessons for engineers

    MaxMine has rolled out a production-grade machine learning system for load and dump classification across Australian mine fleets operated by Glencore, NRW Holdings and Macmahon, with the platform now running continuously for six months. The edge-deployed models automatically tag truck payload events in near real time, sharply cutting missed or misclassified loads and reducing manual data cleaning by site engineers. Early results point to tighter haulage cycle control and more reliable production reporting, giving dispatch and planning teams higher-confidence payload and cycle-time data.
