REalloys Tanbreez Rare Earth Offtake Strengthens Heavy Rare Earth Supply Route

REalloys

REalloys Tanbreez rare earth offtake has moved into a binding 15-year agreement, giving the US rare earth producer long-term access to concentrate from Critical Metals’ Phase 1 Tanbreez project in southern Greenland. The deal replaces a previous letter of intent and strengthens REalloys’ feedstock position for heavy rare earth metals and alloys.

REalloys Tanbreez rare earth offtake covers 15% of monthly production from the project. Phase 1 Tanbreez is expected to produce up to 15,000 t/yr of rare earth concentrate once operations begin.

REalloys Tanbreez rare earth offtake is strategically important because Tanbreez is one of the world’s largest known heavy rare earth element deposits. The project contains significant quantities of dysprosium and terbium, two of the most critical inputs for high-performance permanent magnets.

Pricing will be based on a market-referenced formula with floor-price protection on specified payment elements, subject to finalisation. That structure gives both sides exposure to market value while adding downside protection for selected materials.

Tanbreez Feedstock Supports Heavy Rare Earth Security

Tanbreez gives REalloys a potential long-term concentrate source outside China. That matters because heavy rare earth supply remains one of the most constrained parts of the magnet value chain.

Dysprosium and terbium are especially important because they help permanent magnets maintain performance at high temperatures. These materials are used in electric vehicles, wind turbines, robotics, defence systems, aerospace platforms and advanced industrial motors.

Critical Metals owns 92.5% of the Tanbreez project. The binding offtake agreement gives the project a stronger commercial link to downstream processing and metal production.

The agreement also shows how rare earth buyers are moving earlier into project supply. Securing concentrate before production begins can reduce future feedstock risk and support project financing logic.

However, Tanbreez still needs to move from resource potential to operating supply. The company has not indicated when production will begin, so the timing of actual concentrate deliveries remains a key uncertainty.

REalloys Builds Processing Platform Across Allied Markets

REalloys is positioning itself as a processor and producer of rare earth metals and alloys, not only a project developer. The company aims to begin commercial-scale production of dysprosium, terbium and neodymium metals and alloys in January 2027.

That target is important because rare earth oxides and concentrates must be converted into metals and alloys before they can fully support magnet manufacturing. Metallisation remains a major bottleneck in non-China rare earth supply chains.

REalloys also owns the Hoidas Lake project in Saskatchewan, Canada, and partners with the Saskatchewan Research Council on rare earth separation and processing. These links give the company a North American processing base.

The company also has collaborations in the US, Brazil and Kazakhstan. This broader network suggests REalloys is trying to build diversified feedstock and processing routes rather than relying on a single source.

For western magnet supply chains, that approach is necessary. Heavy rare earth security depends on multiple connected stages: mining, concentration, separation, metal-making, alloying and magnet production.

The Tanbreez agreement therefore adds another piece to the non-China rare earth puzzle. Its value will depend on whether Greenland concentrate can be delivered, separated and converted into qualified metal products at commercial scale.

The Metalnomist Commentary

This agreement shows that heavy rare earth strategy is moving from resource headlines toward long-term feedstock control. REalloys’ challenge is to turn Tanbreez concentrate into qualified dysprosium, terbium and neodymium products before supply-chain pressure intensifies further.
