| Those REE deposits in development that have the greatest chances of success (i.e. being developed into a mine, and thus, offering the highest share price appreciation potential no matter if REE prices remain low) are those that host a REE mineralization out of which a >30% TREO mineral concentrate can be produced with an industry standard process that makes economic sense.
Unfortunately for REE investors, today there exist not many undeveloped REE deposits hosting a mineralization out of which a high enough grade mineral concentrate can be produced, and easily processed, which would be saleable to global REE processors (also known as separation or refining facilities), and from which the numerous REE end-products, which are saleable to the industry, could be produced...............................................Full Article: Source
