U.S.-Saudi Joint Venture Aims to Establish Rare Earths Refinery

On November 19, 2023, MP Materials, in collaboration with the U.S. Department of Defense and Saudi Arabian Mining Company (Maaden), announced plans to construct a rare earths refinery in Saudi Arabia. This initiative is part of a broader strategy to enhance the processing of critical minerals in the Middle East, particularly in light of the ongoing geopolitical tensions surrounding rare earth supply chains dominated by China. The announcement coincided with Saudi Crown Prince Mohammed bin Salman’s visit to Washington, aimed at reinforcing economic and security ties between the U.S. and Saudi Arabia.

Under the joint venture agreement, MP Materials and the Pentagon will collectively hold a 49% stake in the refinery, while Maaden will retain a 51% share. This partnership is seen as a pivotal step in rebalancing the global rare earth supply chain, aligning with U.S. economic and national security interests. The refined materials produced will not only support the defense sectors of both nations but will also be marketed to allied countries, thereby reducing reliance on adversarial sources.

Saudi Arabia's Vision 2030 initiative has positioned mining as a critical pillar of its economy, aiming to diversify beyond oil. The kingdom claims to have $2.5 trillion in untapped mineral wealth, with plans to transform its mining sector into a global player. The establishment of the rare earths refinery is part of this broader strategy, which includes significant investments in mining partnerships with international companies and a focus on critical minerals such as copper, lithium, and nickel.

The Saudi Public Investment Fund (PIF) and Maaden are actively pursuing global mining investments to secure long-term supply chains for essential minerals. Recent partnerships include a $2.5 billion acquisition of a stake in Vale Base Metals and ongoing negotiations for projects in Zambia and Pakistan. These moves are designed to enhance Saudi Arabia's role in the global minerals market and ensure a steady supply for domestic industries, including electric vehicles and defense.

Despite the ambitious plans, there are challenges and criticisms surrounding Saudi Arabia's mining strategy. Analysts caution that the kingdom's heavy investments in foreign mining projects could detract from domestic initiatives outlined in Vision 2030. Additionally, the complexity of rare earth processing, which involves separating 17 different metals, poses logistical challenges that could hinder the refinery's operations.

Furthermore, Saudi Arabia's increasing involvement in global mining raises concerns about its ability to navigate the political and regulatory landscapes of other countries, particularly in regions with resource nationalism and human rights issues. The kingdom's strategy may also lead to increased competition with other nations, notably China, which currently dominates the rare earth processing sector.

MP Materials emphasized that the joint venture represents a significant advancement in securing critical supply chains and enhancing industrial resilience. The company stated, “This partnership is a pivotal step toward rebalancing the global rare earth supply chain.” Meanwhile, the Pentagon highlighted the importance of reducing dependency on China for strategic metals, noting that the demand for rare earth magnets in U.S. military applications is expected to triple by 2030.

As the joint venture progresses, further developments in Saudi Arabia's mining partnerships and the establishment of the refinery are anticipated. The Future Minerals Forum 2026 is set to be a significant event for discussing mineral security and supply chains, drawing international attention to Saudi Arabia's evolving role in the global mining landscape.
