The Trump administration is in talks to acquire an equity stake in Critical Metals Corp, giving Washington a direct interest in Greenland’s Tanbreez rare earth project — one of the world’s largest undeveloped deposits, four people familiar with the matter told Reuters.
If completed, the deal would mark a significant political and strategic move for the United States, deepening its role in Greenland’s mineral sector — the same Arctic territory former President Donald Trump once proposed purchasing outright.
Critical Metals, a New York–based company, acquired the Tanbreez project in 2024 for $5 million in cash and $211 million in stock, after the Biden administration successfully pushed for the sale to a Western buyer rather than a Chinese firm.
The company has since applied for a $50 million grant under the Defense Production Act, a Cold War-era program that supports domestic production of materials essential for national security. According to three sources, the administration has begun discussions about converting that grant into an equity stake worth roughly 8%, although negotiations remain preliminary.
A senior Trump administration official told Reuters that “hundreds of companies” had approached Washington seeking investment, and that “there is absolutely nothing close with this company at this time.”
Critical Metals did not respond to requests for comment. Greenland, while self-governing, remains part of Denmark, whose embassy in Washington also declined to comment.
The Tanbreez deposit, located in southern Greenland, is considered a cornerstone for Western efforts to diversify rare earth supply chains away from China, which currently dominates more than 80% of global production and processing. The project also hosts valuable gallium and tantalum, both of which are under Chinese export restrictions.
Bringing the mine to commercial operation is expected to cost $290 million, with production forecast at 85,000 tonnes of rare earth concentrate per year by 2026. The U.S. Export-Import Bank (EXIM) is separately considering a $120 million loan to support mine development, according to sources.
The potential U.S. investment follows other government-backed moves in the sector, including stakes in Lithium Americas and MP Materials, underscoring Washington’s strategy to secure critical minerals for electric vehicles, defense systems, and renewable technologies.
Even before Trump’s renewed engagement with Greenland, the U.S. had maintained a longstanding presence on the island — including one of its largest Air Force bases — and successive administrations have sought to increase economic and strategic cooperation.
Analysts note that the harsh Arctic environment and Greenland’s slow regulatory processes remain challenges to large-scale mining. However, the project could play a central role in the West’s efforts to counter China’s dominance in the rare earth supply chain.
