    MP Materials–Saudi rare earth JV: supply chain and project notes for engineers

    MP Materials–Saudi rare earth JV: supply chain and project notes for engineers

    First reported on MINING.com

    30 Second Briefing

    MP Materials has formed a Saudi rare earth refinery joint venture with Maaden and the US Department of War, with MP and DoW holding 49% and Maaden at least 51%, sending MP’s shares up 8.2% and its market capitalisation to nearly $11 billion. The DoW will fully finance the US equity stake, while MP contributes separation and refining know-how drawn from its Mountain Pass mine and processing complex in California and its magnet plant in Texas. The refinery will process Saudi and imported feedstock into separated light and heavy rare earth oxides for US, Saudi and allied defence and manufacturing supply chains, with magnet manufacturing collaboration in the kingdom under discussion.

    Technical Brief

    • MP’s prior DoW partnership includes up to $1 billion capex for US refining and magnet capacity.
    • Expansion at Mountain Pass specifically targets increased heavy rare earth separation capability within the existing integrated complex.
    • A second US magnet manufacturing facility is planned under the public–private partnership framework announced in July 2025.
    • Saudi refinery siting is driven by low-cost energy, existing industrial infrastructure and port-linked export logistics.
    • Feedstock strategy combines Saudi rare earth resources with imported concentrates from other producing regions.
    • Output will include both light and heavy rare earth oxides, enabling full-spectrum downstream alloy and magnet supply.
    • China’s current ~60% share of global mine supply and dominant processing capacity frames the supply-chain risk being addressed.

    Our Take

    With China still providing about 60% of global rare earth mine supply, a Saudi-based JV anchored by MP Materials gives downstream users in the US and Middle East an alternative feedstock route that is less exposed to Chinese export policy risk.

    The planned US$1 billion MP investment alongside a minimum 51% Ma’aden stake signals that Saudi Arabia is positioning rare earths alongside its existing phosphate and base metals portfolio, which could pull more processing and magnet-making know‑how into the Middle East over the coming years.

    The inclusion of a 13 Mt tungsten trioxide resource in Portugal in the same investment narrative suggests MP and its backers are already thinking beyond light rare earths, with potential to build a broader critical minerals platform that can leverage the same processing and offtake relationships.

    Epiroc–Major Drilling DiscovOre system: safety and cycle-time notes for drill engineers

    Epiroc and Major Drilling are advancing the DiscovOre and Arrow 3S wireline core barrel system, first introduced in 2016 to boost mineral exploration drilling performance while reducing manual handling at the drill string. The system integrates a latch mechanism and overshot design that allow inner tubes to be retrieved without workers leaning over the rotating drill string, cutting exposure to dropped-object and entanglement hazards. Current development focuses on further cycle-time reductions and safer operation in deep-hole, high-angle exploration drilling.

    Civmec’s A$400m BHP and Fortescue awards: delivery and ECI notes for project teams

    Civmec has secured more than A$400 million in new contracts and extensions with BHP and Fortescue, converting a previously flagged pipeline of brownfield and sustaining capital opportunities into firm work. The awards, spanning structural, mechanical and piping packages as well as site maintenance, are structured around early-contractor involvement to lock in constructability and schedule before final investment decisions. For project teams, this signals continued demand for integrated fabrication–construction delivery and long-term shutdown and upgrade support on major iron ore operations in Western Australia.

    Trapper target at Saga’s Radar project: grade and resource lens for mine planners

    Initial drilling at Saga Metals’ Radar iron-titanium-vanadium project in Labrador has defined Trapper as its strongest target, with hole R-0009 cutting 296 m from 2.5 m depth grading 39.75% Fe₂O₃, 7.46% TiO₂ and 0.25% V₂O₅, including 63 m at 44% Fe₂O₃ and 9% TiO₂. A second hole, R-0008, returned 269.36 m at 36.21% Fe₂O₃, 6.57% TiO₂ and 0.244% V₂O₅ from 3.4 m, with internal intervals up to 46.15% Fe₂O₃ and 9.2% TiO₂. Saga reports Trapper’s iron and titanium grades are 124% and 105% higher than Hawkeye’s best assays, supporting a 15,000 m programme targeting an indicated resource later in 2026.
