Minami-Tori-Shima area rare earths deposits
- In 2012, Japanese scientists discovered about 6.8 million tons of rare earth elements (“REEs”) near the island, enough to supply Japan’s current consumption for over 200 years. At that time, around 90% of the world’s production of REE comes from China, and Japan imports 60% of that.
- In 2013, the location of deposits was confirmed to be approximately 250 km south of island itself, in the sea-bottom sediments under 5600 to 5800 m of water. The rare-earth elements unusually high concentration of 0.66 % was also confirmed.
- In 2014, the Japanese government has assigned a task of developing a necessary rare earths mining technology to a company Mitsui Mining & Smelting Co., Ltd.
