USAR Rare Earth Plant Brings $1.2bn Magnet Investment to South Carolina

USA Rare Earth rare earth plant

USAR rare earth plant plans will bring a major new magnet and metal manufacturing complex to Cherokee County, South Carolina. USA Rare Earth will invest $1.2bn in the Blacksburg project as part of a broader $3.5bn capital programme backed by federal and private funding.

USAR rare earth plant capacity will include 6,400 t/yr of rare earth magnets and 5,000 t/yr of strip-cast metal and alloy. The facility will be built at Bailey Industrial Park and is scheduled for commissioning in 2028.

USAR rare earth plant development will complement the company’s recently commissioned magnet facility in Stillwater, Oklahoma. Together, the projects are intended to build a more integrated US rare earth processing and permanent magnet supply chain.

Engineering and equipment procurement are already under way, while site preparation is expected to begin in the coming months.

Blacksburg Adds Metal and Magnet Capacity to US Supply Chain

The South Carolina project is significant because it combines rare earth metal and alloy production with finished magnet manufacturing.

This integration addresses one of the main weaknesses in the US rare earth value chain. Producing separated oxides is not enough. Those materials must be converted into metals, alloys and magnet feedstock before they can serve automotive, defence and industrial customers.

Strip casting is a critical step in NdFeB magnet manufacturing because it converts rare earth metals and other inputs into controlled alloy structures suitable for downstream powder production and magnet fabrication.

The planned 5,000 t/yr metal and alloy capacity therefore gives USAR greater control over intermediate material supply. The 6,400 t/yr magnet line then extends that control further downstream.

The project could serve growing demand from electric motors, robotics, aerospace, defence systems and advanced manufacturing. These industries increasingly require reliable non-China magnet supply.

The Blacksburg location also expands USAR’s manufacturing footprint beyond Oklahoma, giving the company a broader domestic production base.

Federal Funding Supports Large-Scale Magnet Buildout

USAR has secured substantial government backing for its expansion. The company executed a definitive agreement with the US Department of Commerce that unlocks $1.6bn in federal support.

The package includes a $1.3bn loan and $277mn in federal funding. In return, the Department of Commerce will receive common stock and warrants.

USAR also raised $1.5bn in private capital in January 2026, bringing total committed capital to around $3.5bn.

This funding structure highlights how rare earth magnet manufacturing is becoming part of US industrial policy. Public capital is being used to reduce financing risk for projects that compete with established Chinese supply chains.

The key challenge now is execution. USAR must complete construction, commission the plant, secure feedstock and qualify products with customers by 2028.

If successful, the South Carolina project would add meaningful domestic capacity in both rare earth alloys and finished magnets, strengthening one of the most strategically sensitive parts of the US critical minerals supply chain.

The Metalnomist Commentary

USAR’s South Carolina project shows that US rare earth policy is moving decisively from mining toward full-chain manufacturing. The strategic value lies in controlling the metal, alloy and magnet stages where non-China supply remains most constrained.
