U.S. firm GreenMet On Thursday announced a landmark partnership with Tanbreez, marking a major step in securing reliable supplies of heavy rare earth elements (HREEs) for North American and European markets.
The Tanbreez Project, located in southern Greenland and owned by New York-based Critical Metals Corp, holds one of the world’s largest untapped HREE deposits outside China, with a vast 4.7 billion-tonne mineralized kakortokite unit.
The site also contains gallium, a critical material for high-tech industries, which China restricted exports of last year.
The partnership comes amid heightened geopolitical tensions, as U.S. President Donald Trump continues to advocate for the takeover of Greenland from Denmark as part of his “America First” policy.
The Tanbreez Project, with its mix of high-value HREEs, zirconium, and niobium, has an impressive Preliminary Economic Assessment (PEA) for 2025, projecting a $3.04 billion net present value (NPV).
With nearly 27 percent deposit of heavy rare earths, Tanbreez is uniquely positioned to serve U.S. and European markets, supporting next-generation technologies and defense applications.
“We are thrilled to partner with Tanbreez and Critical Metals Corp to unlock one of the largest rare earth resources outside of China,” GreenMet CEO Drew Horn said.
“As the only shovel ready rare earth project in Greenland, Tanbreez represents a game-changing opportunity for both the Greenlandic economy and the critical minerals supply chain in North America and Europe,” he added.
Strategic and economic importance
Strategically located with deep-water fjord access and close to existing infrastructure, the Tanbreez project ensures efficient material transportation.
With a mining license secured through 2050, it offers long-term operational stability. Its low-radiation profile and geopolitical safety make it a reliable source of critical materials for the Western world.
Once operational, Tanbreez is set to become a key supplier of rare earth elements (REEs), particularly for the defense sector and high-tech industries, strengthening its role in the global rare earth supply chain.
It has set an aim to mine 500,000 metric tons annually of the crimson rare earths-containing mineral eudialyte as soon as 2026.
The collaboration could also provide a fillip to the Greenlandic economy, offering job creation, infrastructure development, and the growth of local industries.
Great geopolitical interest
Greenland, located off Canada’s northeastern coast, has long been strategically important to North American defense.
During World War II, the U.S. occupied the island to prevent it from falling under Nazi control and to safeguard key North Atlantic shipping routes.
Today, Greenland’s vast mineral wealth has made it a focal point of geopolitical interest, particularly as Western nations, including the U.S., seek to reduce reliance on China for critical minerals.
Rare earth elements possess potent magnetic properties, making them indispensable to high-tech sectors—from powering electric vehicles to enabling advanced missile systems.
