Japan embarks on its first deep-sea uncommon earth mining expedition

A Japanese deep-sea mining ship departed in the present day on the planet’s first experimental extraction of so-called “rare earth mud” from the ocean ground. The transfer is Japan’s first try at sourcing uncommon earth components (REEs) domestically, with an ambition to scale back dependency on Chinese provides.

The government-backed scientific drilling vessel, Chikyu, departed in the present day from Shimizu Port in Shizuoka. It is headed to waters close to Minamitori Island, a distant coral atoll roughly 1,900 kilometres southeast of Tokyo. 

The mission is led by Schoichi Ishii of the Cabinet Office’s ocean innovation platform, and can use pipes deployed by a Japan Agency for Marine-Earth Science and Technology (JAMSTEC) vessel.

The staff will spend one month trying to gather uncommon earth-rich mud located some 6,000 metres beneath the floor to extract REEs. If profitable, a full-scale mining trial might be carried out in February 2027. 

The challenge has gone forward regardless of environmental and scientific communities issuing stark warnings concerning the “irreversible harm” deep-sea mining inflicts on ocean ecosystems.  

Rare earth components like Neodymium, Dysprosium and Terbium, are at present used within the manufacturing of electrical autos, wind turbine turbines, smartphones, and army gear. 

Japan is sort of solely depending on China for some REEs, notably these used for magnets in electrical and hybrid automobile motors. Last week, nevertheless, China banned exports of dual-use gadgets – items, software program, or know-how which have each civilian and army makes use of – to Japan. This contains uncommon earth components which are essential for making items like drones and chips, posing a serious danger for the nation’s key automotive business.
