    MP Materials’ $1.25B Texas magnet plant: supply chain and capex lens for mine planners

    First reported on MINING.com

    30 Second Briefing

    MP Materials will build its $1.25 billion “10X” rare earth magnet manufacturing campus on a 120-acre site in Northlake, Texas, less than 10 miles from its existing Fort Worth plant, targeting commissioning in 2028. The fully integrated platform, supplied with feedstock from the Mountain Pass mine in California, is expected to support total output of about 10,000 tonnes per year of NdFeB magnets and include mining, refining, metallisation, alloying, sintering and closed‑loop recycling. Funding includes a $1 billion JPMorgan/Goldman facility, a $150 million Pentagon loan and $200 million in state and local incentives.

    Technical Brief

    • Engineering and equipment procurement for 10X is already underway ahead of site construction.
    • MP plans to create over 1,500 direct manufacturing and engineering roles at the Northlake campus.
    • The 10X campus is sited less than 10 miles from MP’s existing Fort Worth magnet plant.
    • State and local authorities have approved a $200 million package of grants, abatements and tax exemptions over >10 years.
    • MP’s integrated platform already spans mining, refining, metallisation, alloying, sintering, finished magnets and closed‑loop recycling.
    • Concentration of both plants in North Texas effectively establishes a regional hub for US rare earth magnet manufacturing.

    Our Take

    Texas is emerging as a rare earths–magnet hub in our coverage, with MP Materials’ 10X facility in Northlake complementing USA Rare Earth’s Round Top project and planned Lacq (France) alloy plant, suggesting future competition and potential collaboration around NdFeB supply chains anchored in the state.

    The combination of Apple’s $500 million investment and the $1 billion commitment from JPMorgan Chase and Goldman Sachs positions MP Materials as one of the more heavily financed rare earth players in our database, which is likely to pressure smaller US rare earth developers on both cost of capital and offtake access.

    MP Materials’ partnership with the US Department of War at Mountain Pass and in the Saudi refinery JV with Maaden signals that this NdFeB magnet build-out in Texas is part of a wider defence-linked strategy to reduce reliance on China for rare earth materials and magnets rather than a stand-alone commercial move.

    True North legacy mine funding and peers: exploration takeaways for project teams

    True North Copper has secured $5 million in Queensland Government funding to restart exploration at the legacy Cloncurry copper project, targeting extensions to historical high-grade lodes using modern geophysics and deeper diamond drilling. Aureka is ramping up RC and diamond drilling across its Western Australian gold tenements, focusing on structurally controlled shear-hosted mineralisation near existing 1–2Mtpa processing hubs to fast-track potential toll treatment. Rincon is expanding silver and base metal exploration in South Australia with step-out drilling around known vein systems and updated 3D geological modelling to refine resource targets.

    New tech for Australia’s untapped copper: cut-off grade impacts for mine planners

    A breakthrough electrochemical processing technology for low‑grade copper ores has secured $5 million in Federal Government funding in Australia. The process targets previously uneconomic resources, aiming to recover copper from low‑grade and complex deposits that conventional flotation and smelting struggle to treat. If scaled, the technology could materially change project cut‑off grades, extend mine lives at existing operations, and open new deposits in underexplored Australian copper provinces.

    Boss Honeymoon recovery plan: ISR wellfield spacing and cost lens for engineers

    Boss Energy is pursuing a new development pathway for the Honeymoon uranium operation in South Australia based on an alternative wide-spaced in-situ recovery wellfield layout. The concept aims to reduce drilling density and capital per pound of U₃O₈ while maintaining flow rates and leach contact, potentially cutting operating costs across the existing plant and satellite wellfields. For geotechnical and hydrogeological teams, the approach will hinge on demonstrating sufficient hydraulic connectivity, containment within the mineralised aquifer and reliable long-term recovery under the wider spacing.
