(TELEGRAPH) — Japanese scientists have found vast reserves of rare earth metals on the Pacific seabed that can be mined cheaply, a discovery that may break the Chinese monopoly on a crucial raw material needed in hi-tech industries and advanced weapons systems.
"We have found deposits that are just two to four metres from the seabed surface at higher concentrations than anybody ever thought existed, and it won't cost much at all to extract," said professor Yasuhiro Kato from Tokyo University, the leader of the team.
While America, Australia, and other countries have begun to crank up production of the seventeen rare earth elements, they have yet to find viable amounts of the heavier metals such as dysprosium, terbium, europium, and ytterbium that are most important.

China has a near total monopoly in the heavier end of the spectrum, though it is also the dominant supplier of the whole rare earth complex after driving rivals out of business in the 1990s. It still accounts for 97pc of global supply.
