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

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.
