US Rare Earths Supply Gains Momentum as Traxys Partners With Phoenix Tailings

Traxys & Phoenix

US rare earths supply is gaining a stronger commercial platform after Traxys North America partnered with Phoenix Tailings on feedstock sourcing, offtake, and strategic support. The agreement links Phoenix’s rare earth metallization capacity with Traxys’ global trading network at a time when Western buyers are seeking alternatives to China-dominated rare earth supply chains.

The partnership will allow Traxys to provide global feedstock sourcing and downstream metal sales for Phoenix. This is strategically important because rare earth supply security depends not only on mining, but also on conversion into usable metals for magnets, electronics, defence systems, and advanced manufacturing.

US rare earths capacity remains limited, especially in heavy rare earth metals such as dysprosium and terbium. Phoenix produces samarium, yttrium, dysprosium, terbium, and other rare earth elements. These materials are critical for high-performance magnets, aerospace systems, clean energy technologies, and defence-linked applications.

Phoenix Tailings Expands the US Rare Earth Metals Platform

Phoenix Tailings operates a rare earth metallization facility in Exeter, New Hampshire, with current capacity of 200 t/yr of light and heavy rare earth metals. The facility has the potential to expand to 1,000 t/yr, giving the company a meaningful growth pathway in a market where Western metallization capacity remains scarce.

The Traxys Phoenix Tailings partnership also follows Traxys’ investment in Phoenix’s recent $40.2mn financing round. That funding included $30.2mn in equity and $10mn in venture debt from investors including Eni Next, Geodesic Alliance Fund, and Traxys. The investment shows that rare earth processing is attracting capital from both strategic and financial backers.

This matters because US rare earths development has often focused on mining and separation. However, metallization is a key downstream step. Without metal production capacity, rare earth oxides and intermediates still need further processing before they can enter magnet and advanced materials supply chains.

Traxys Strengthens Rare Earth Offtake and Feedstock Reach

Traxys brings commercial reach to Phoenix through feedstock procurement and downstream metal sales. That role can help reduce one of the biggest challenges for emerging rare earth producers: matching reliable input supply with long-term customer demand.

The partnership also fits Traxys’ broader rare earth strategy. Traxys Europe has a binding offtake agreement with Arafura Rare Earths for up to 300 t/yr of neodymium-praseodymium oxide from the Nolans project in Australia. Arafura has also received a letter of interest for up to $300mn from the US Export-Import Bank to support the project.

Together, these moves show how rare earth supply chains are being built through financing, offtake, trading networks, and processing partnerships. For the US rare earths market, the Phoenix agreement is important because it supports domestic metal production rather than only upstream resource development.

The Metalnomist Commentary

The Traxys-Phoenix partnership shows that rare earth competitiveness will be decided in processing and commercialization, not only in mining. Western supply chains need companies that can secure feedstock, produce metals, and place material into qualified industrial channels.
