Ann: Major Ionic Clay Rare Earth Discoveries at Colossus, page-42

Hello. These are rare earths in clay, which the commercial content will primarily be Neodymium , Praseodymium , Dysprosium , Terbium and possibly Yttrium. The average grade is 2,000 to 3000 parts per million or 0.2% to 0.3%. If these grades were in rock, they would not be economically recoverable. But they are in clay, making them easy to recover, hopefully for a cost of around US$35 - $40/kg; selling for around US$85/kg (currently). The company IXR has done a feasibility study on their African deposit but their African deposit does not look as good (economic) as VMM and MEI.
