Ucore Rare Matals, operating at Bokan Mountain in Alaska, and Sweden's Tasman Metals will both have REE production coming on line eventually, and on estimates will produce 120tpa and 350tpa of dysprosium. Rare Earth Element Resources of Wyoming could also boast a significant desposit. There are other deposits that are less well known and could be "sleepers". One is Lynas' Duncan deposit in Australia. There are also significant dysprosium deposits in Australia owned by Hastings Rare Metals and Northern Minerals , although these projects are "quite early".
