CD-Rom in paper sleeve. Zustand: very good. This report presents results of a study conducted between 1992 and 1996 to assess the undiscovered metallic mineral resources in the U.S. Bureau of Land Management's (BLM) Winnemucca District and Surprise Resource Area (WSRA), northwest Nevada and northeast California. A wide variety of mineral deposits are present throughout the WSRA, and they are hosted by rocks and surficial deposits ranging in age from lower Paleozoic to Quaternary that is, from approximately 570 million years (Ma) to about 1 Ma. The main metal commodities present in the WSRA, from a commercial standpoint, are gold, silver, and, to a lesser extent, tungsten. Gold currently accounts for most mining activities in the WSRA production of approximately 1.2 million oz Au occurred from 10 mines during 1995. Eight of these 10 mines also produced approximately 7.4 million oz Ag for a combined annual gross value of approximately $550 million. Gold in the WSRA is produced mostly from three types of deposits: (1) sediment-hosted (Carlin-type) deposits, (2) hotspring and vein-type epithermal gold-silver deposits, and (3) distal-disseminated silver-gold deposits. Some additional gold and silver production also is derived from a variety of less important types of mineral deposits, including minor production from placers.CD.…
