The deposits, estimated at 16 million tons, lie at a depth of 5,700 meters about 250 km south of Minami-Torishima island in the Pacific Ocean.
It was estimated that the deposits contain enough dysprosium, which is used in the production of hybrid auto motors, to last for 730 years, and 420 years’ worth of terbium, which is used in magneto-optical discs, among other things.
