The Saudi rare earth joint venture between Maaden and MP Materials is built around one clear goal: create a rare earth refinery in Saudi Arabia. The partners said the project will expand Middle Eastern processing of critical minerals. It is also tied to a new U.S.–Saudi framework on securing critical supply chains that was signed in Washington, D.C.
This deal is a three-party structure. MP Materials is partnering with the U.S. Department of Defense and state-owned Saudi mining company Maaden. Reuters reported that, under the deal, MP and the Defense Department will hold a combined 49% stake in the refinery, while Maaden will hold the remaining 51%.
Several reports repeat the same ownership split. Reuters says 49% for MP plus the Defense Department and 51% for Maaden. Mining.com says Maaden will retain no less than 51% while MP and the Defense Department joint venture holds a combined 49%. Benzinga says Maaden will hold at least 51% and MP plus the Defense Department JV will collectively hold up to 49%.
The refinery plan is not just about local ore. MP Materials said the facility will be designed to process rare earth feedstock sourced from Saudi Arabia and other global regions. It is also meant to produce significant quantities of separated light and heavy rare earth oxides. Those products are positioned to support U.S. and Saudi manufacturing and defense sectors and be marketed to allied nations.
Why This JV Helps Saudi Act Like a Rare Earth Hub
Hub status depends on processing and logistics, not only mining. MP Materials said the joint venture will leverage Saudi Arabia’s competitive energy base, world-class infrastructure, and strategic location. It also cited significant untapped rare earth resource potential. Together, these points describe why a refinery in the Kingdom could become a central node for feedstock coming from multiple regions.
The partnership is also designed to align with security goals. CNBC reported the binding agreement is structured to “ensure U.S. oversight and alignment with national security objectives.” Mining.com adds that the Defense Department will provide full financing for the U.S. contribution, while MP contributes technical expertise in separation and refining. That mix can make it easier to build capacity while keeping close coordination with U.S. priorities.
