USA Rare Earth’s $19.3M DOE backing: supply chain and project lens for miners
Reviewed by Tom Sullivan
First reported on MINING.com
30 Second Briefing
USA Rare Earth has been selected by the US Department of Energy for up to $19.3 million in funding under the Critical Materials Innovation, Efficiency and Alternatives programme to build a pilot-scale rare earth separations facility, within a $50.5 million project backed by $31.2 million in non-DOE capital. The company is pursuing a fully integrated rare earths and magnet supply chain, adding UK-based Less Common Metals in 2025 and a 12.5% stake in French processor Carester SAS in April, alongside a proposed $1.6 billion US Department of Commerce package. A separate $2.8 billion acquisition of Brazil’s Serra Verde and its Pela Ema mine, which could supply about half of ex-China heavy rare earth output by 2027, is under antitrust review in Brazil and includes a 15-year US offtake for Nd, Pr, Dy and Tb.
Technical Brief
- DOE selection is under final scope, budget and timing negotiations, so pilot schedule remains fluid.
- Federal funding is via the Critical Materials Innovation, Efficiency and Alternatives programme targeting critical minerals processing.
- Non-DOE capital of $31.2 million implies majority private or non-DOE risk exposure for the separation plant.
- USA Rare Earth’s market capitalisation rose to about $5.3 billion after a 5.6% share price increase.
- Less Common Metals acquisition in 2025 secures upstream rare earth metals and alloy production capacity in the UK.
- April investment bought a 12.5% equity stake in French processor Carester SAS for separation expertise access.
- Serra Verde’s Pela Ema mine in Goiás is Brazil’s only producing rare earth operation, in commercial production since 2024.
- Brazil’s antitrust authority has opened a competition investigation into the $2.8 billion Serra Verde acquisition structure.
- Serra Verde forecasts Pela Ema could supply ~50% of ex-China heavy rare earth output by 2027.
- USA Rare Earth is targeting vertically integrated mining-to-magnet supply for aerospace, defence, semiconductor, energy and data-centre clients.
Our Take
USA Rare Earth's DOE-backed separations work at Round Top sits alongside its proposed $2.8 billion acquisition of Brazil’s Serra Verde (operator of the Pela Ema rare earth mine), signalling a dual-track strategy to control both upstream NdPr-heavy ore in Goiás and downstream processing capacity in the US.
In our database of 1195 Mining stories, relatively few rare earth items combine US federal funding with active antitrust scrutiny abroad; here, Cade’s probe into the Serra Verde deal means USA Rare Earth must advance critical minerals ambitions while navigating Brazilian competition and permitting risk.
The mix of DOE grant support and a separate conditional $80 million loan offer to ReElement Technologies underlines how US critical minerals policy is now splitting roles between funding domestic rare earth processing and backing allied supply from Brazil, reducing over-reliance on China for heavy rare earths such as dysprosium and terbium.
