Of over 12,000 mines recorded in Nevada by the USGS, over 5,500 are listed as gold producers. Over 3,300 mines are listed as silver producers.

USGS recently assumed the responsibility for the creation and dissemination of this and other periodic publications, such as the Minerals Yearbook and Mineral Industry Surveys. USBM was abolished by Congress in January 1996, but about 190 federal and contract employees and support staff that had prepared these and other reports were transferred to the USGS in Reston, Va., and Lakewood, Colo
