The U.S. has very large deposits of rare earths in Mountain Pass, California, south of Los Vegas, and in fact had at least one working mine and processing plant there until the Chinese undercut world prices in the 1990s, and Congress foolishly allowed the Mountain Pass facility to close.  Now there are efforts to open it back up (along with similar facilities in a number of other countries that were also closed in the 1990s  for the same reason).
