The US just secured control of one of the largest heavy rare earth deposits on earth outside China.

It's in Greenland.

American mining company Critical Metals Corp has received formal approval from the Greenland government to acquire 70% of the Tanbreez deposit in southern Greenland.

Estimated resource: 4.7 billion tonnes of rare earth bearing material.

27% of those rare earths are heavy rare earth elements (dysprosium, terbium, yttrium ) the ones used in EV motors, wind turbines, and advanced military systems.

For context:

Mountain Pass, California (the main US deposit): 0.49% heavy rare earths

Bayan Obo, China's largest deposit: 1.13%

🚨Tanbreez: 27%

It also has exceptionally low uranium and thorium content 10--20 ppm uranium, under 100 ppm thorium.

That matters because radioactive contamination has killed other Greenland projects.

Tanbreez already holds a mining licence valid until 2050 one of only 2 sites out of 140+ active licences on the island to have received it.

The supply chain logic is straightforward:

Extract in Greenland → process in the US → supply defence and advanced technology sectors

Production is expected to begin 2027--2028, starting at 85,000 tonnes of rare earth oxides per year, scalable to 425,000 tonnes.

Project value estimated at $3 billion.

China controls 85% of global rare earth processing capacity.

The US currently imports 80% of its rare earths from China.
