U.S.-Denmark-Greenland Deal Expands Arctic Defense Access-and Draws a Line Around Critical Minerals

Highlights

• The U.S.-Denmark-Greenland framework announced September 18 expands American military access while restricting adversarial 'sensitive investments' including critical minerals.
• Greenland's sovereignty remains with the Danish Kingdom, and the deal requires parliamentary approval before taking effect.
• Projects like Tanbreez and Kvanefjeld face unresolved challenges including eudialyte processing economics, radioactive waste, Arctic infrastructure deficits, and lack of non-Chinese separation capacity.
• Security guarantees may attract Western capital but cannot substitute for proven metallurgy, ports, power, skilled labor, or a mine-to-magnet supply chain.
• Analysts warn that Greenland's impressive rare earth resources do not equal economically recoverable or financeable products under current conditions.
