Rare Earth Elements Extraction

from waste mine tailings and other previously unrecoverable deposits

CMC is developing rare earth element (“REE”) extraction techniques for use at old mine tailings properties located throughout the U.S. CMC's goal is to be in a position provide a secure reliable supply of both light and heavy REEs to U.S. manufacturers and defense contractors.

The tailings remnants from many old mines which previously operated in the US are on the surface, accessible and depending on the original ore mined, contain significant concentrations of Rare Earth Elements. The REE’s include, for example, Neodymium (Nd), Praseodymium (Pr), Cerium (Ce), Lanthanum (La), Yttrium (Y) and many others.

As a result of developing new proprietary extraction techniques, these previously unrecoverable deposits are now available at numerous existing operating and closed mining sites which are easily permitted in order to operate modern, state of the art, safe and environmentally clean extraction facilities.

In many cases, this processing of existing tailings and ore rubble piles, which can otherwise leach into groundwater over time, can constitute a beneficial remediation and clean-up activity for the mine property owner, which provides an additional benefit, in addition to receiving royalties from REEs production.
