USA Rare Earth France Investment Targets Integrated European Magnet Supply Chain

USA Rare Earth

USA Rare Earth France investment plans will deploy more than $203mn by 2030 to expand rare earth separation, metal, alloy and magnet manufacturing capacity. The move strengthens France’s position in Europe’s effort to build a complete rare earth value chain outside China.

USA Rare Earth France investment builds on the company’s acquisition of UK-based Less Common Metals and its planned investment in French rare earth specialist Carester. Together, the projects connect oxide separation with rare earth metals, alloys, recycling and eventual magnet manufacturing.

USA Rare Earth France investment is strategically important because Europe still has major gaps between rare earth feedstock and finished permanent magnets. Building these intermediate processing stages is essential for automotive, defence, aerospace and industrial customers seeking diversified supply.

French government incentives, debt guarantees and potential direct equity investment in USAR’s European subsidiary could support the expansion. This shows how public capital is increasingly being used to make non-China rare earth processing commercially viable.

Lacq Links Rare Earth Oxides With Metals and Alloys

USAR acquired Less Common Metals for $125mn in September and plans to develop a 3,750 t/yr rare earth metal and alloy facility at Lacq in southwestern France.

The location is strategically important because the LCM facility will be co-located with Carester’s 1,600 t/yr Ceramag rare earth oxide plant. Ceramag is scheduled to start commissioning in late 2026.

Co-location can shorten the supply chain between separated oxides and metal or alloy production. This reduces logistics complexity and helps create a more integrated industrial cluster.

Rare earth metals and alloys are critical intermediate products. Separated neodymium, praseodymium, dysprosium and terbium oxides must undergo further conversion before they can enter high-performance NdFeB magnet manufacturing.

This metallisation stage remains one of the largest bottlenecks outside China. Building oxide, metal and alloy capacity in the same region could therefore give Europe a stronger base for permanent magnet production.

Recycling and Automotive Offtake Strengthen Commercial Case

Carester adds both recycling capability and long-term customer demand to the platform. Its Caremag project is designed to recycle 2,000 t/yr of permanent magnets and refine 5,000 t/yr of mining concentrate.

That combination gives the project access to both secondary and primary feedstock. Recycling can improve supply resilience, while mined concentrate provides additional volume for larger-scale production.

Carester also has a 10-year supply agreement with Stellantis covering more than 3,400t of neodymium, praseodymium, dysprosium and terbium oxides. This gives the European rare earth chain a direct connection to automotive demand.

USAR and InfraVia Capital Partners are also considering minority investments in Carester. Under the current term sheet, each could hold a 12.5% equity interest.

This structure combines technology, industrial customers, private capital and government support. That mix is increasingly necessary because rare earth projects face high capital costs, difficult qualification requirements and competition from established Chinese producers.

The strategic goal is larger than any single plant. France is becoming a hub where separation, recycling, metallisation, alloying and magnet production could increasingly operate within one regional ecosystem.

The Metalnomist Commentary

USAR’s French expansion shows that rare earth diversification is moving toward industrial clustering rather than isolated projects. Europe’s real breakthrough will come when recycled and mined feedstock can move continuously from oxide to metal, alloy and qualified magnet inside the region.
