Critical Metals Corp. (Nasdaq: CRML) announced today it has signed a binding 15-year offtake agreement with REalloys Inc. for the supply of rare earth elements from its Tanbreez Project in Greenland. The deal secures a long-term buyer for 15% of the project’s annual production.
The agreement focuses specifically on high-value heavy rare earth elements (HREEs), primarily dysprosium and terbium. These minerals are essential for the production of high-performance permanent magnets used in electric vehicle (EV) motors, wind turbines, and defense technologies. This contract represents one of the longest offtake commitments in the current rare earths market.
Consolidating Control in Greenland
The offtake announcement follows the recent consolidation of the Tanbreez Project’s ownership. Critical Metals Corp. now holds a 92.5% stake in the asset after the Government of Greenland approved the transfer of the final 50.5% interest. European Lithium Ltd (ASX: EUR) retains the remaining 7.5% as a minority financial partner.
By securing majority control, Critical Metals Corp. has removed the primary hurdle to project financing and strategic partnerships. The move allows the company to transition from an explorer into a developer with clear operational authority over what is considered one of the world’s largest multi-element rare earth deposits.
Strategic Importance of Dysprosium and Terbium
The focus on dysprosium and terbium is a strategic decision aimed at the “magnet metals” market. While light rare earths like neodymium and praseodymium are more common, heavy rare earths provide the heat resistance required for magnets to operate in extreme environments, such as EV drivetrains.
Currently, China controls nearly 90% of global heavy rare earth processing. The deal with REalloys, a Western-aligned mid-stream processor, is designed to bypass this dominance. REalloys will take the high-grade eudialyte concentrate from Tanbreez and convert it into alloys and other downstream products for industrial users in North America and Europe.
| Feature | Details of the CRML-REalloys Agreement |
|---|---|
| Duration | 15 Years (Binding) |
| Volume | 15% of total annual production |
| Primary Minerals | Dysprosium (Dy), Terbium (Tb) |
| Source Material | High-grade eudialyte concentrate |
| Geographic Focus | Western-aligned supply chain (U.S., EU) |
| Project Ownership | 92.5% Critical Metals Corp. |
Project Profile: The Tanbreez Advantage
The Tanbreez Project is unique due to its mineralogy and scale. Unlike many rare earth projects that rely on monazite or bastnäsite, Tanbreez is hosted in eudialyte. This mineral allows for simpler processing and higher yields of heavy rare earths.
The project is located on the southern tip of Greenland with year-round access to deep-water shipping lanes. This infrastructure advantage significantly reduces the capital expenditure (CAPEX) typically associated with remote Arctic mining. With billions of tonnes of mineralized material, Tanbreez has the potential to supply the global market for decades.
Market Impact and Supply Chain Security
The global demand for critical minerals is expected to triple by 2030, driven by the energy transition. Policymakers in Washington and Brussels have designated dysprosium and terbium as “highest risk” due to their supply concentration.
“Securing a 15-year offtake for dysprosium and terbium is a massive de-risking event for the project,” said one industry analyst familiar with the deal. “It provides the revenue visibility that Tier-1 banks require before committing the hundreds of millions in debt financing needed to build the mine.”
For REalloys, the deal ensures a steady stream of feed material that is not subject to the export quotas or geopolitical tensions often associated with Asian supply chains. This partnership positions both companies at the forefront of the burgeoning Western rare earth mining category.
De-risking Through Partnerships
Critical Metals Corp. has been aggressive in its pursuit of mid-stream partners. Beyond REalloys, the company has engaged with other processors in the U.S. and Europe to test its eudialyte concentrate. The 15-year term of the current deal suggests that REalloys has high confidence in the quality and extractability of the Tanbreez ore.
The consolidation of the 92.5% stake was the final catalyst needed to finalize these terms. Investors have been watching Critical Metals Corp. closely as it navigates the complex mining stocks landscape, where control and offtake are the two most critical metrics for project success.
Next Steps for Tanbreez
With the offtake secured and ownership consolidated, Critical Metals Corp. is expected to move into the final feasibility stage. This will involve optimizing the flow sheet for the eudialyte ore and finalizing the environmental impact assessments required by the Greenlandic authorities.
The company has indicated that construction could begin within the next 24 to 36 months, pending final investment decisions (FID). The 15% annual production coverage provides a baseline of cash flow, but the company remains in a strong position to negotiate the remaining 85% of its output as demand for heavy rare earths continues to climb.
Conclusion: A New Hub in the North
The Tanbreez-REalloys partnership is more than a commercial contract; it is a signal of the shifting geography of the global mining industry. By leveraging Greenland’s massive resources and a direct pipeline to Western industry, Critical Metals Corp. is attempting to rewrite the rare earth playbook.
As the energy transition accelerates, projects that can provide long-term, secure, and heavy-REE-rich supply will command a premium. For now, the 15-year offtake stands as a significant milestone in bringing one of the world’s most strategic mineral assets into production.
