    Japan deep seabed rare-earth mud test: system design and impacts for miners

    Japan deep seabed rare-earth mud test: system design and impacts for miners

    First reported on MINING.com

    30 Second Briefing

    Japan will run a month-long pilot from 11 January to 14 February to continuously lift rare-earth-rich mud from about 6,000 m depth near Minamitorishima Island, targeting 350 t/day via a full integrated deep-sea mining system 1,900 km southeast of Tokyo. The Japan Agency for Marine-Earth Science and Technology will monitor environmental impacts both on the seabed and onboard while operating within Japan’s exclusive economic zone. Dewatering will occur on Minamitorishima using spin-dryer-style equipment to cut mud volume by roughly 80% before shipment to mainland refineries, following ¥40 billion of government funding since 2018.

    Technical Brief

    • Strategic Innovation Promotion Program is directing the work, targeting a domestically controlled rare earths supply chain.
    • No formal production target or resource tonnage has been disclosed, limiting current economic feasibility assessments.
    • Dewatered concentrate will still require transport from Minamitorishima to mainland Japan for separation and refining.
    • Government funding totals about ¥40 billion since 2018, covering exploration, system development and pilot operations.
    • The test area lies within Japan’s exclusive economic zone, simplifying permitting but sharpening geopolitical sensitivities.

    Our Take

    The Japan rare earths push around Minamitorishima sits alongside other non-Chinese supply strategies in our database, such as Iluka Resources’ and Lynas Rare Earths’ projects highlighted in the Wood Mackenzie–centred piece from 11 December 2025, signalling a multi-continent effort to dilute China’s dominance in refined rare earths.

    A government-funded spend of about ¥40 billion since 2018 on seabed mud extraction suggests Japan is treating this as strategic infrastructure rather than a pure R&D exercise, which could give downstream Japanese magnet and electronics manufacturers more leverage in long-term offtake negotiations referenced in broader critical minerals coverage.

    Testing the ability to handle 350 t/d of deep-sea mud with an 80% volume reduction is technically significant because it directly addresses one of the main bottlenecks flagged in other rare earths projects in our coverage: the cost and logistics of moving and processing very low-grade, high-mass feedstocks at scale.

    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.
