US in talks to establish three military bases in Greenland, with rare earth minerals in the crosshairs

The United States is negotiating with Denmark to build three military bases in southern Greenland. Negotiations have progressed in recent months, with the White House reportedly optimistic about reaching a deal.

The proposed bases would focus on monitoring Russian and Chinese maritime activity in the GIUK Gap, the strategically critical stretch of ocean between Greenland, Iceland, and the United Kingdom that serves as a chokepoint for naval traffic moving between the North Atlantic and the Arctic. One of the proposed locations is Narsarsuaq, a former US base that Washington operated during World War II and the Cold War.

High-level talks are being led by the State Department’s Michael Needham. Denmark has confirmed an “ongoing diplomatic track” but hasn’t offered specifics.

Cold War echoes, new century stakes

The negotiations build on a 1951 defense pact between the US and Denmark that already permits American military expansion in the territory. Thule Air Base, now called Pituffik Space Base, has operated in northern Greenland under that agreement for decades.

The proposed deal could grant the US sovereign territory over the bases, a step beyond the existing arrangement.

The rare earth angle

Greenland sits on roughly 25% of the world’s undiscovered rare earth elements, according to the US Geological Survey. These minerals, things like neodymium, dysprosium, and lanthanum, are essential for everything from electric vehicle motors to semiconductor manufacturing to the specialized hardware used in cryptocurrency mining rigs.

China currently dominates the global rare earth supply chain, controlling an estimated majority of mining, processing, and refining capacity. Recent Trump-NATO discussions reportedly included explicit mention of “cooperation on mineral development” tied to Greenland’s resources, linking Arctic defense to the broader push for supply chain independence.

Greenland Minerals, an Australia-listed company with significant rare earth holdings on the island, has seen its stock rise roughly 8% over the past 30 days as Arctic security developments have accelerated. Rare earth element spot prices are up about 5% year-to-date, driven largely by supply anxiety.

ASIC miners, the specialized machines that power Bitcoin’s proof-of-work network, rely on rare earth magnets and components. GPU-based mining operations face similar dependencies.

What this means for investors

There are risks worth flagging. Greenland’s autonomous government has historically been cautious about large-scale mining projects, and local opposition has blocked or delayed several proposals in recent years. A military base deal with Denmark doesn’t automatically unlock mining permits, which require separate approval from Greenland’s parliament.

Sovereignty provisions over proposed bases could become a sticking point, both for Denmark’s domestic politics and for Greenlandic leaders who have been increasingly vocal about self-determination.
