Researchers have found hundreds of years’ worth of critical rare-earth metals beneath Japanese waters — enough to supply to the world on a “semi-infinite basis,” according to a study published on Tuesday.
The materials sit in a roughly 965-square-mile Pacific Ocean seabed near Minamitorishima Island, which is located 1,150 miles southeast of Tokyo, according to the study published in Nature Publishing Group’s Scientific Reports.
Rare-earth metals are crucial in the making of high-tech products such as electric vehicles, mobile phones and batteries, and the world has relied on China for almost all of its rare-earth material.
The seabed contains more than 16 million tons of rare-earth oxides, according to the study. That’s equivalent to 780 years’ worth of yttrium supply, 620 years of europium, 420 years of terbium and 730 years of dysprosium, it added.
The discovery “has the potential to supply these metals on a semi-infinite basis to the world,” the study said.
