Key Points:
- Critical Metals Corp secured 92.5% ownership of the massive Tanbreez rare earth project in Greenland after obtaining local government approval.
- The company approved a $30 million acceleration program to fast-track drilling and metallurgy, targeting first ore production by late 2028.
- A $120 million loan letter of intent from the U.S. EXIM Bank will support financing, alongside two major U.S. offtake agreements covering 25% of output.
- The Tanbreez deposit contains a massive 4.7-billion-tonne host rock, serving as a critical non-Chinese source of heavy rare earth elements.
A major shift is underway in the global critical minerals sector as the West races to break China’s tight grip on strategic supply chains. In a landmark development, the government of Greenland has approved the transfer of the remaining 50.5% interest in the massive Tanbreez rare earth project to New York-based Critical Metals Corp. This critical regulatory approval raises the company’s total ownership stake in the asset to 92.5%, giving it absolute operational and strategic control over one of the largest undeveloped heavy rare earth deposits in the world.
The geostrategic importance of the Tanbreez project, located in Southern Greenland near Qaqortoq, cannot be overstated. Currently, China controls approximately 70% of global rare earth mining and over 90% of the world’s refining capacity. This near-monopoly allows Beijing to weaponize exports through restrictive controls, creating severe supply chain risks for Western electronics, clean energy, and defense sectors. By securing direct control of Tanbreez, Critical Metals is establishing a reliable, non-Chinese source of critical heavy rare earth elements, such as dysprosium, terbium, and yttrium.
The sheer scale of the Tanbreez deposit represents a genuine game-changer for the industrial metals market. Based on company estimates, the entire geological structure contains a staggering 4.7 billion tonnes of mineral-rich host rock. The main orebody alone holds at least 45 million tonnes of resources, with heavy rare earths accounting for approximately one-third of that total. These specific elements are vital for manufacturing high-performance permanent magnets, which power everything from electric vehicle motors and wind turbines to advanced military guidance systems.
To rapidly bring this massive resource into production, the board of Critical Metals has approved a $30 million acceleration program. This specialized funding will fast-track active drilling, metallurgy studies, and infrastructure engineering at the Arctic site. The company plans to begin pilot plant operations as early as May, followed by a 150-tonne bulk sample program in June. These immediate, near-term milestones support a target timeline of first ore production by late 2028 or early 2029, with concentrate exports scheduled to begin in the third quarter of 2029.
The project’s rapid development has also secured significant backing from the United States government. The U.S. Export-Import (EXIM) Bank recently issued a $120 million Letter of Intent for a 15-year term loan to support the project’s development and financing. This federal support highlights how deeply Washington views critical minerals as a matter of national security, especially as geopolitical tensions between the United States and China continue to escalate.
To further solidify its commercial pathway, Critical Metals has already lined up key supply deals with major U.S. processors. The company signed a ten-year offtake agreement with Ohio-based REalloys, securing sales for 15% of the mine’s monthly Phase 1 production. This contract follows an earlier agreement to supply 10% of its production to Ucore Rare Metals, bringing the total committed offtake to 25% of Tanbreez’s expected output. Both deals ensure that a significant portion of the mine’s heavy rare earth elements will flow directly into protected U.S. defense, nuclear, and critical infrastructure networks.
The development of the Tanbreez project also benefits from exceptional geographical and logistical advantages. Unlike other remote Arctic mineral deposits that remain locked behind permanent ice for most of the year, the southern Greenland site offers year-round direct shipping access. Deep-water fjords lead directly from the mine’s edge to the North Atlantic Ocean. This allows bulk cargo vessels to easily transport raw concentrates directly to processing hubs in North America and Europe without relying on expensive overland transport or seasonal shipping windows.
As the global race for critical minerals heats up, the successful consolidation of the Tanbreez project positions Critical Metals as a leading player in the clean energy transition. By combining massive physical resources, secure U.S. government backing, and committed commercial offtake agreements, the company is translating the conceptual goal of supply chain independence into a practical reality. The coming years will prove whether this Greenlandic asset can successfully rebalance the global rare earth market and secure a reliable future for Western technology.
