    Mariana Copper One autonomy-first mine and refinery: retrofit lessons for engineers

    Mariana Copper One autonomy-first mine and refinery: retrofit lessons for engineers

    First reported on International Mining – News

    30 Second Briefing

    Mariana Minerals plans to turn its Copper One operation in southeastern Utah into what it calls the world’s first “autonomy‑first” integrated copper mine and refinery, building on an existing open pit, heap bioleach pads and a hydrometallurgical circuit already producing high‑purity cathode for the US market. The brownfield site, in operation for over 15 years and acquired by Mariana in late 2025, is being re‑engineered around autonomous haulage and drilling, with refinery process control also targeted for high levels of automation. For engineers, the key shift is retrofitting autonomy into established pit geometries, leach pad layouts and plant circuits rather than designing greenfield infrastructure.

    Technical Brief

    • Existing heap bioleaching operation is being retained as the primary leach method rather than conventional SX-EW.
    • Hydrometallurgical refining circuit is configured to produce high-purity copper cathode suitable for direct US offtake.
    • Brownfield open pit geometry and haul road alignments constrain how autonomous haulage routes can be overlaid.
    • Legacy heap pad stacking patterns and solution collection systems must be integrated with autonomy-ready stacking and reclaim equipment.
    • Control philosophy is shifting towards refinery-wide advanced process control rather than isolated loop optimisation.
    • For other brownfield mining sites, the project offers a live test case for autonomy retrofits without major re-excavation.

    Our Take

    With Copper One in Utah targeting an autonomy-first mine and refinery for copper, it sits alongside Boliden’s “green fleet” roll-out in Europe as one of the few copper stories in our database explicitly tying fleet modernisation to decarbonisation and productivity in both mining and downstream processing.

    The site’s 15+ years of prior operation before Mariana Minerals’ 2025 acquisition suggests a brownfield automation strategy, which typically allows faster deployment of autonomous haulage and plant control than greenfield builds because orebody knowledge and basic site infrastructure are already de-risked.

    McEwen’s $55M Ontario asset sale: production growth lens for mine planners

    McEwen has agreed to sell its Fuller and Paymaster gold properties in Ontario’s Timmins district to Discovery Mining for $55 million in cash and stock, freeing capital to push a production target of 250,000–300,000 gold-equivalent ounces per year by 2030. The deal covers 210 hectares at Fuller, a 60% stake in the 179-hectare Paymaster property, and associated surface rights, consolidating Paymaster under Discovery’s Dome Mine subsidiary. Proceeds will be reinvested into the Fox Complex (Froome, Stock, Grey Fox), Nevada’s Gold Bar Complex, and Mexico’s El Gallo build, with Stock Mine slated for first ore in Q4 2026 and commercial output in Q1 2027.

    Lithium Triangle extraction hurdles: hydrogeological insights for project teams

    South America’s Lithium Triangle holds about 64 million tonnes of identified lithium resources (43% of the global 150 million tonnes), yet geologist José Cabello’s review of 43 salt flats across Argentina, Bolivia and Chile shows that variable brine chemistry, impurities and groundwater behaviour make recovery and costs highly site-specific. Salar de Atacama benefits from ultra‑dry climate, relatively clean brines and strong logistics, while other basins such as Altoandinos, Pedernales, Hombre Muerto Oeste, Rincón, Sal de los Ángeles and Sal de Vida face tighter water and hydrogeological constraints. Direct lithium extraction (DLE) could unlock lower‑grade or impurity‑rich brines, but Cabello stresses that trade‑offs between brine withdrawal and freshwater consumption mean technology selection must be tailored to each basin’s hydrology and ecosystem.

    KGHM’s $2.4bn copper projects fast-tracked: CRMA implications for mine planners

    EU regulators have granted strategic status under the Critical Raw Materials Act to KGHM’s 9.5‑billion‑zloty ($2.44bn) Retków‑Grodziszcze mine and Legnica smelter conversion, unlocking faster permitting, streamlined administration and access to preferential financing. Retków‑Grodziszcze is planned to deliver over 100 million tonnes of ore by 2055, yielding about 1.5 million tonnes of copper and 5,000 tonnes of silver, while Legnica’s recycling line targets 135,000 tonnes of electrolytic copper and 250 tonnes of nickel per year. The move materially boosts EU copper and nickel recycling capacity, central to the CRMA’s 25% recycling target.
