Mineral resources in Taos County, New Mexico
— V. T. McLemore and K. E. Mullen
There are ten types of deposits in the nine mining districts of Taos County, New Mexico. Four of these are worldclass mineral deposits: molybdenum at Questa (Questa district), perlite at No Agua (No Agua district), mica at the U. S. Hill mine in the Picuris Mountains (M.I.C.A. district), and the Harding pegmatite (Picuris district). All of these deposits are currently producing with the exception of the Harding pegmatite, which is owned by the University of New Mexico for use as a field classroom and amateur mineral collecting site. Ten aggregate (sand and gravel) mines also are currently operating. Future mineral production in Taos County is certain, especially at three of the previously mentioned world-class deposits (Questa, No Agua, U. S. Hill mine), and of sand and gravel in the aggregate mines in the vicinity of Taos and along the Rio Grande.
