Critical Metals rare earth offtake strengthens US magnet supply chain

REalloys

The new Critical Metals rare earth offtake with REalloys signals a decisive shift in North American magnet sourcing. Under the agreement, Critical Metals will allocate 15pc of its heavy and medium rare earth feedstock from the Tanbreez project in Greenland. The Critical Metals rare earth offtake could total up to 6.8mn t of concentrates over the multi-year term. This volume will give REalloys a steady pipeline of rare earth concentrates for downstream refining in the US. REalloys will process the feedstock at its Euclid, Ohio facility, which already supplies rare earth magnet materials and alloys into defence and industrial markets. The company is a supplier to the US Defense Logistics Agency, linking Tanbreez material directly to strategic US security needs. As a result, the Critical Metals rare earth offtake strengthens the emerging US effort to reduce dependence on Chinese rare earth supply.

US rare earth ecosystem deepens through multi-partner strategy

The agreement with REalloys comes on top of Critical Metals’ earlier deal with Canadian processor Ucore Rare Metals. That arrangement secures 10pc of Tanbreez rare earth feedstock for Ucore’s processing capacity. Together, these staged allocations show how Critical Metals is spreading Tanbreez output across multiple North American processors. This reduces single-buyer risk while helping regional refiners lock in secure feedstock. Meanwhile, both REalloys and Ucore can plan investments in separation, alloying and magnet metal capabilities with greater confidence. The Tanbreez deposit’s mix of heavy and medium rare earths is especially important for high-performan`ce magnets. These include defence platforms, electric vehicles, wind turbines and advanced industrial equipment where supply security is now a board-level concern. If project execution proceeds as planned, the Critical Metals rare earth offtake framework could become a reference model for future mine-to-magnet partnerships.

The Metalnomist Commentary

Critical Metals is quietly building a de-risked customer base even before Tanbreez reaches full production, which is a smart move in a volatile price environment. By locking in offtake with both REalloys and Ucore, the company positions Tanbreez as a backbone asset in a broader North American rare earths ecosystem rather than a standalone mine. The key questions now are project timing, permitting and capital discipline, all of which will determine how quickly this strategic feedstock can translate into real magnet capacity.
