MP Materials Magnet Campus in Texas Expands US Rare Earth Manufacturing Capacity

MP Materials

MP Materials magnet campus plans in Northlake, Texas, mark a major step in building a larger US rare earth magnet supply chain. The company’s planned “10X” facility will lift its total neodymium-iron-boron magnet production capacity to about 10,000 t/yr.

The MP Materials magnet campus is expected to require more than $1.25bn in investment. Engineering and equipment procurement are already underway, and commissioning is scheduled for 2028. The project strengthens the company’s position as one of the few integrated Western rare earth producers moving from mining and refining into finished magnet production.

The location also carries strategic value. Northlake sits fewer than 10 miles from MP’s existing Independence facility in Fort Worth, allowing the company to build a regional magnet manufacturing cluster with shared industrial infrastructure, workforce development, and supply-chain connectivity.

Texas Incentives Support Domestic Magnet Scale-Up

Texas, Denton County, and the City of Northlake approved an incentive package worth $200mn over a decade. The package includes grants, abatements, and exemptions designed to support one of the most capital-intensive segments of the rare earth value chain.

This support reflects the strategic importance of neodymium-iron-boron magnets. These magnets are used in electric motors, robotics, drones, defense systems, wind power, industrial automation, and advanced electronics. For the US, domestic magnet capacity is becoming a national competitiveness issue as China continues to dominate much of the rare earth processing and magnet manufacturing chain.

The MP Materials magnet campus also expands the company’s role beyond raw material supply. MP describes itself as an integrated magnet producer, with activities spanning mining, refining, metallization, alloying, sintering, finished magnet production, and recycling. That vertical model is important because rare earth supply security depends on every step between ore and magnet-ready components.

Northlake Adds Scale to Fort Worth Magnet Platform

MP’s existing Independence facility in Fort Worth provides the foundation for the Northlake expansion. Independence has 1,000 t/yr of magnet production capacity, with a 2,000 t/yr expansion already underway. That site is also anchored by a partnership with Apple focused on magnet recycling.

The Northlake project adds a much larger scale-up pathway. By targeting about 10,000 t/yr in total neodymium-iron-boron magnet capacity, MP is positioning itself to serve higher-volume demand from automotive, electronics, energy, and defense customers.

Recycling will also become more important as magnet demand grows. Recovered magnets can provide an additional rare earth feedstock stream and reduce pressure on primary supply. In a market exposed to geopolitical risk, recycling can strengthen domestic material resilience and improve traceability.

The Metalnomist Commentary

MP’s Northlake project shows that the US rare earth strategy is shifting from mining announcements to industrial execution. The critical test will be whether domestic magnet production can scale with competitive costs, qualified customers, and reliable feedstock flows.
