President Donald Trump renewed his call for the United States to control Greenland during a NATO summit in Ankara, arguing the Arctic island is vital for national security and global protection. Trump stated the U.S. had made a historic mistake by returning control of Greenland to Denmark after World War II, saying, "We took Greenland and then, stupidly, we gave it back." He emphasized the need for the island to protect the world, not just the United States. The remarks overshadowed the summit and drew a firm rebuttal from Danish Prime Minister Mette Frederiksen, who asserted that Greenland is not for sale and that Denmark would defend "every inch" of the NATO territory while respecting the island's right to self-determination.

Trump tied the dispute to broader complaints about NATO allies receiving a "free ride" under the U.S. security umbrella. He suggested the U.S. could withdraw troops from Europe if resistance to his proposal continued, arguing that Europe's opposition strained ties with the alliance. He also reiterated claims that Greenland is threatened by Chinese and Russian military activity, a point experts have previously disputed. The President argued that because Denmark does not spend enough to help Greenland, the U.S. should control it to ensure regional defense against Russia.

Strategic and Economic Importance

Greenland serves as a strategic chokepoint, housing the Pituffik Space Base, America’s northernmost military installation, which supports missile defense and space surveillance. The island also anchors the Greenland-Iceland-U.K. (GIUK) Gap, a corridor governing Russian naval access to the Atlantic. Beyond geography, Greenland holds reserves of as many as 17 critical metals, including tungsten and heavy rare earths essential for advanced weapons systems and electric motors. The Kvanefjeld deposit contains approximately 1 billion tons of ore at a 1.1% rare-earth concentration, while the nearby Tanbreez project holds an estimated 5 million tons of rare-earth oxides.

Companies such as Shenghe Resources, Critical Metals Corp., Energy Transition Minerals, Greenland Mines Ltd., and NioCorp Developments Ltd. are targeting these resources to strengthen Western supply chains and reduce dependence on China. Shenghe Resources remains the largest shareholder in Kvanefjeld, despite Greenland's uranium mining ban freezing the project. Critical Metals Corp. (NASDAQ: CRML) completed an acquisition of Tanbreez, after U.S. lobbying helped prevent a sale to Chinese buyers. The Center for Strategic and International Studies has noted the island's potential but advised that development should occur through coordinated investments and long-term diplomatic commitments.

Diplomatic Standoff

Greenland’s Industry Minister, Naaja Nathanielsen, previously called the idea of ceding sovereignty a "red line," stating it is not on the table. A working group of officials from the U.S., Denmark, and Greenland is continuing talks on the issue, with Danish Foreign Minister Lars Løkke Rasmussen expressing hope for a solution by year-end. Finnish President Alexander Stubb downplayed the tensions, urging leaders to "be more Arctic, be more cool" and allow discussions to proceed.

Greenland Mines Ltd has concluded a three-day technical workshop to define the next phase of development for the Skaergaard Precious and Critical Metals Project in southeast Greenland. The workshop, held from June 22 to June 24, 2026, brought together more than 15 international experts from organizations including GTK Mintec, Geological Survey of Finland, SLR Consulting, and WSP. The session focused on advancing the understanding of the orebody, building a technical foundation for upcoming fieldwork, and defining a roadmap toward an Initial Assessment (IA) or Preliminary Economic Assessment (PEA).

The program included in-depth discussions on geological frameworks, metallurgical test work, and the 2026 drilling campaign. Greenland Mines is advancing a broader metallurgical and processing workstream at Skaergaard with GTK Mintec, including flowsheet development. The company has also engaged SLR as geological and mining consultants and WSP Denmark for environmental baseline work.

2026 Field Program and Logistics

The field program will operate with three helicopter-portable drill rigs on site, adapted for diamond exploration drilling in rugged terrain. Greenland Mines has contracted helicopter support for the campaign and previously secured an icebreaker and accommodation base camp vessel with a helicopter platform for the 2026 field season. The drilling campaign is expected to include a mix of HQ and NQ core drilling in vertical and angled holes.

Technical Objectives and Roadmap

The workshop outcomes include an updated integrated plan for the 2026 drilling and sampling campaign, a refined strategy for metallurgical test work, and a framework for integrating geotechnical and environmental data into mine design. The company views this coordinated approach as a key differentiator for Skaergaard as a potential large-scale, long-life precious and critical metals project in the Arctic. The agreed roadmap extends beyond the IA/PEA toward potential exploitation license application and long-term development options.
