U.S.-Greenland Security Pact Tightens Control Over Rare Earth Supply…

Event summary

The U.S., Denmark, and Greenland announced a security agreement on September 22, 2026, requiring U.S. approval for sensitive investments in Greenland's critical minerals sector.
Greenland Mines Ltd. (NASDAQ: GRML) applied to more than double its Sarfartoq rare earth district license area, covering approximately 262 km² east of its existing license.
The Sarfartoq ST1 deposit has a mineral resource estimate of 6.9 million tons Indicated at 1.60% TREO and 5.3 million tons Inferred at 0.96% TREO, with a high-case pre-tax NPV of approximately $2.05 billion.
REalloys Inc. (NASDAQ: ALOY) secured a long-term offtake agreement with Critical Metals Corp. for 15% of monthly Phase 1 production from the Tanbreez Project in southern Greenland.

The big picture

The global rare earth elements market is projected to reach $6.28 billion by 2030, driven by demand for electric-vehicle traction motors, offshore wind turbines, and grid-scale clean-energy infrastructure. The U.S.-Greenland security agreement marks a strategic shift, framing Greenland's mineral deposits as part of allied security planning rather than remote geology. This move is likely to accelerate the development of rare earth supply chains outside of China, where supply remains highly concentrated.
