Critical Metals Surges Up to 43% as Trump-Denmark Greenland Security Pact Spotlights Tanbreez Rare Earth Deposit

Shares of Critical Metals Corp. (NASDAQ: CRML) surged as much as 43% in Monday trading after President Donald Trump announced Friday, September 19, that the United States had reached a security agreement with Denmark and Greenland giving Washington "permanent control over security, and all other needs" over the Arctic island. The deal, expected to be formally signed during the United Nations General Assembly, also establishes a U.S. military presence in Greenland and bars non-NATO members from setting up military bases there.

The announcement reignited investor focus on Critical Metals' Tanbreez project in southern Greenland, one of the world's largest undeveloped heavy rare earth deposits, which holds key elements including terbium and dysprosium used in magnets, electronics, and defense technology. The company currently holds a 92.5% stake in Tanbreez through a pending $835 million merger with European Lithium Ltd., which, if approved by shareholders, would bring ownership to 100%. Critical Metals also recently reported more than 99% dissolution of Tanbreez concentrate into 19 high-purity products, along with a study projecting $1.8 billion to $2.2 billion in potential annual refinery revenue.

Other Greenland-linked stocks posted even larger moves, with Greenland Mines (GRML) up as much as 177% and Greenland Energy (GLND) up roughly 140% to 159% on the day. Broader rare earth peers saw smaller sympathy gains, with USA Rare Earth rising about 6% and MP Materials climbing around 4%, reflecting what analysts characterized as asset-specific pricing at Tanbreez rather than a sector-wide re-rating. Related ETFs tied to CRML were reported up as much as 75%.
