Greenland Mining Stocks CRML, GLND, GRML Skyrocket After Trump Unveils Permanent US Security Deal

Greenland mining stocks surge marked one of the most dramatic overnight rallies in recent memory, as shares of Critical Metals, Greenland Energy, and Greenland Mines exploded higher late Sunday following President Trump’s announcement of a sweeping, permanent security agreement granting the United States extensive access to the Arctic island.

Trading activity told the story clearly: CRML jumped 34 percent, GLND rocketed an astonishing 150 percent, and GRML climbed 72 percent, all within a single overnight session, as investors rushed to position themselves ahead of what many see as a transformative shift in Greenland’s strategic and economic future.

What Trump’s Announcement Actually Says

Trump revealed the agreement through a Truth Social post Friday, describing a deal with Denmark and Greenland that grants Washington what he called permanent control over security and all other needs across the Arctic territory. He added that the United States would immediately begin developing a substantial military presence on the island, emphasizing this would come at no cost to American taxpayers.

According to a State Department official familiar with the arrangement, the agreement carries no expiration date and grants the US permanent access, basing rights, and overflight privileges. The deal also explicitly bars non-NATO countries from establishing their own military bases in Greenland and gives Washington authority to block adversarial nations from making sensitive investments on the island. Notably, these provisions would remain in effect even if Greenland eventually achieved full independence from Denmark.

Secretary of State Marco Rubio characterized the agreement as permanently and completely resolving longstanding US national security concerns, ensuring Greenland remains part of North America’s strategic defense area indefinitely. Officials from both governments expect to formally sign the agreement during this week’s United Nations General Assembly, though it will still need to clear required parliamentary approval processes afterward.

Denmark And Greenland Push Back On Sovereignty Concerns

Despite the sweeping nature of the security provisions, both Denmark and Greenland moved quickly Saturday to clarify that the agreement does not transfer sovereignty over the territory to Washington. Danish Prime Minister Mette Frederiksen emphasized that the deal explicitly recognizes the sovereignty and territorial integrity of the Danish Kingdom, along with the Greenlandic people’s right to self-determination.

Greenlandic Prime Minister Jens-Frederik Nielsen offered a similarly measured assessment, describing the agreement as one that recognizes Greenland’s own interests and its place within international cooperation, framing it as beneficial for all parties involved. Importantly, this arrangement falls notably short of Trump’s earlier, more aggressive push to purchase or outright annex Greenland, representing a significant scaling back of his original ambitions.

Mining Companies Position For Rare Earth Supply Chain Growth

The dramatic stock surge reflects growing investor enthusiasm about Greenland’s mining sector, particularly as Western nations work to reduce dependence on Chinese rare-earth mineral supplies.

Critical Metals has emerged as a central player in this broader strategic push. Just last week, the company reported achieving more than 99 percent dissolution of Tanbreez concentrate into 19 high-purity products, alongside a new study projecting potential annual refinery revenue between 1.8 billion and 2.2 billion dollars. The company’s proposed 835 million dollar merger with European Lithium also advanced toward a shareholder vote, a deal that could increase Critical Metals’ ownership stake in the Tanbreez project from 92.5 percent to full ownership.

Beyond that merger, Critical Metals signed a 15-year supply agreement with REalloys back in May, covering 15 percent of Phase 1 production output. Washington has also reportedly considered providing a 120 million dollar loan through the Export-Import Bank, along with a potential direct equity investment in the company. The company is currently targeting first ore production sometime in late 2028 or early 2029.

Greenland Mines, which had publicly welcomed the security pact last week, completed its 35 million dollar acquisition of the Sarfartoq project earlier this month. An assessment conducted in August estimated a high-case pretax valuation of 2.05 billion dollars for the project, with the company suggesting its eventual output could represent as much as 34 percent of non-Chinese refined neodymium-praseodymium supply globally. The company also recently wrapped up a substantial 104.8-ton bulk-sampling program at its Skaergaard site.

Meanwhile, Greenland Energy reached indicative terms this month to acquire its joint venture partner, 80 Mile, for approximately 61.48 million pounds, a move that would consolidate the company’s position in the Jameson Land project while adding the Disko-Nuussuaq and Dundas assets to its portfolio. However, drilling activity at Jameson Land was pushed back in August to winter 2027, pending further regulatory review.

Retail Investors Show Overwhelming Bullish Sentiment

Trading platform Stocktwits showed retail sentiment running extremely bullish across all three stocks, with message volume reaching extremely high levels for both CRML and GLND, and high volume for GRML as well.

One user on the platform suggested the timing wasn’t coincidental, drawing a connection between the Greenland announcement and Chinese President Xi Jinping’s upcoming visit, noting that Trump had employed a similar strategic timing approach before a previous trip to China.

Another user speculated about the potential for a significant short squeeze developing across GRML and GLND shares given the dramatic overnight price action.

Despite Sunday’s remarkable surge, these stocks remain well below their yearly starting points. CRML has fallen 3 percent year-to-date, while GLND and GRML have plunged 88 percent and 80 percent respectively, underscoring just how volatile this sector has been throughout the year even before this latest dramatic rally.
