Japan has found a large deposit of rare earth minerals in its Pacific seabed, enough to supply its hi-tech industries for more than 200 years, a scientist said Friday.
Around 6.8 million tonnes of the valuable minerals, used in electric cars, iPods and lasers, are sitting under the seabed near a far eastern Japanese island, Tokyo University professor Yasuhiro Kato said.
He said mud samples taken from an area near Minamitorishima island, some 2,000 kilometres (1,250 miles) southeast of Tokyo, indicated deposits amounted to around 220 times the average annual amount used by industry in Japan.
The seabed contained a substantial amount of dysprosium — a rare earth mineral used in the engines for hybrid cars, he said.
