USA Rare Earth’s first commercial yttrium: supply-chain and project notes for engineers
Reviewed by Tom Sullivan
First reported on MINING.com
30 Second Briefing
USA Rare Earth has produced its first commercial pour of 2N–2N5 purity (99%–99.5%) yttrium metal via subsidiary Less Common Metals at its Cheshire, UK facility, joining the small group of non-Chinese commercial yttrium suppliers after 2025 prices spiked about 1,500% on Chinese export curbs. The output underpins USAR’s mine-to-magnet plan anchored by the Round Top rare earth deposit in Texas, targeted for 2028 production, and a newly commissioned sintered neodymium magnet line in Stillwater, Oklahoma, with a potential second magnet plant in France. Backed by a US$1.58 billion Trump administration investment for an 8%–16% equity stake, USAR is positioning to supply aerospace, defence and advanced ceramics users seeking alternatives to Chinese yttrium.
Technical Brief
- Yttrium output is intended to integrate with USAR’s oxide processing capabilities before downstream alloying or component manufacture.
Our Take
The 99–99.5% yttrium from Round Top aligns with USA Rare Earth’s CHIPS-backed plan to build a full mine-to-magnet chain in Texas and Stillwater, suggesting the company is positioning yttrium as an additional revenue stream alongside NdFeB magnet feedstock rather than a standalone product line.
With Washington’s up-to-$1.6 billion support already flagged in our earlier coverage, the share price and market cap uplift around this yttrium milestone indicate investors are now starting to price in value from the deposit’s broader critical minerals basket, not just neodymium-praseodymium for magnets.
Oklahoma’s push to be a processing hub, highlighted in the March 6 coverage of Emirates Global Aluminium and other critical minerals projects, means USA Rare Earth’s Stillwater facilities could benefit from shared infrastructure, workforce and political backing that de-risk commissioning and scale-up of yttrium and other rare earth processing circuits.
