"A new report on the sea floor around Japan’s Minami-Tori-shima, also known as Marcus Island, indicates the mud is positively saturated with rare-earth elements and yttrium, abbreviated REY. (Yttrium is not always classified as a rare-earth element, but is extremely similar.)
The calculated ΣREY for the entire research area is more than 16 million tons of rare-earth oxides (Mt-REO) (average ΣREY=964 ppm). In addition, the mud is especially enriched in Y [yttrium] and HREE [heavy rare earth elements], which accounted for 44% (Y: 4.4 Mt-REO; HREE: 2.6 Mt-REO) of the total amount of REY in this region. The research area was estimated to be able to supply Y, Eu, Tb, and Dy for 780, 620, 420, and 730 years, respectively, and has the potential to supply these metals on a semi-infinite basis to the world."
