Approximately 13 million metric tons of rare earth elements (REE) exist within known deposits in the United States, as per the first-ever nationwide estimate of these elements by the U.S. Geological Survey. This estimate of domestic rare earth deposits is part of a larger report that includes a review of global sources for REE, information on known deposits that might provide domestic sources of REE in the future, and geologic information crucial for studies of the availability of REE to U.S. industry........
