Japanese researchers have mapped vast reserves of rare earth elements in deep-sea mud, enough to feed global demand on a « semi-infinite basis, » according to a fresh study.
The deposit, found within Japan’s exclusive economic waters, contains more than 16 million tons of the elements needed to build high-tech products from mobile phones to electric vehicles, according to the study, released Tuesday in the journal « Scientific Reports. »
The team, comprised of several universities, businesses and government institutions, surveyed the western Pacific Ocean near Minamitorishima Island, Japan.
In a sample area of the mineral-rich region, the team’s survey estimated 1.2 million tons of « rare earth oxide » deposited there, said the study, conducted jointly by Yutaro Takaya, researcher with Waseda University and Yasuhiro Kato of the University of Tokyo, among others.
