"The U.S. Geological Survey has just reported on U.S. REE resources."
The United States Geological Survey has just published an assessment of U.S. resources. The report, Scientific Investigations Report 2010–5220, maybe be downloaded free. For an introduction and links to sections of the report, go here.
The report includes an overview of the geology and mineralogy of rare earth element deposits and gives a description of each domestic prospect.
The USGS estimates that domestic reserves and inferred resources are about 1.5 million tons which is large compared to the peak domestic consumption (in 2007) of 10,200 tons.
