“A U.K.-based private equity firm has found the largest rare earth oxides deposits in the world in North Korea, according to statements by the company. The British firm, SRE Minerals Limited, announced the results of its assessment of North Korea’s deposits last month. Most notably, the company said that it estimates that the Jongju deposit holds 216 million tons of rare earth oxides, which includes light rare earth elements (REEs), heavy REEs, and rare earth minerals. According to Voice of America, this would more than double the current global stockpiles of rare earth oxides, which the U.S. Geographical Survey recently estimated at 110 million tons.”
