Japanese Scientists To Look Into Rare Earth Deposits, Mining Costs

The report added that scientists from the Japan Organization for Metals and Energy Security (JOGMEC) will visit mines in Greenland to study the rare earth deposits as well as the associated mining costs.

It stated that the Japanese officials expect Greenland’s rare earth deposits to contain elements used in electric vehicles, batteries as well as semiconductors. The country had sent a fact finding mission in November last year to Greenland, which concluded that rare earth mining was possible in the country even under its extremely cold weather.

What Is The CRML Connection?

Critical Metals’ flagship Tanbreez Project in Southern Greenland holds one of the world's largest heavy rare earth deposits.

The project contains significant concentrations of dysprosium, terbium and yttrium, which are materials used in permanent magnets for electric vehicles, defense systems, wind turbines, robotics and advanced manufacturing.

Tanbreez also contains hafnium, niobium, zirconium and other minerals used in semiconductors, microchips and AI-related infrastructure.

Critical Metals also announced last month that it had signed a definitive agreement to acquire European Lithium. Once the transaction completes, Critical Metals stake in the Tanbreez Rare Earth Project will increase to 100%, from the existing 92.5%.

The company also announced a long-term rare earth supply agreement with REalloys Inc. (ALOY) for 15% of Tanbreez’s annual rare earth concentrate output.
