Description: These data are part of a larger USGS project to develop an updated geospatial database of mines, mineral deposits and mineral regions in the United States. Mine and prospect-related symbols, such as those used to represent prospect pits, mines, adits, dumps, tailings, etc., hereafter referred to as “mine” symbols or features, are currently being digitized on a state-by-state basis from the 7.5-minute (1:24, 000-scale) and the 15-minute (1:48, 000 and 1:62,500-scale) archive of the USGS Historical Topographic Maps Collection, or acquired from available databases (California and Nevada, 1:24,000-scale only). Compilation of these features is the first phase in capturing accurate locations and general information about features related to mineral resource exploration and extraction across the U.S. To date, the compilation of 400,000-plus point and polygon mine symbols from approximately 51,000 maps of 17 western states (AZ, CA, CO,ID, KS, MT, ND, NE, NM, NV, OK, OR, SD, UT, WA, WY and western TX) has been completed. The process renders not only a more complete picture of exploration and mining in the western U.S., but an approximate time line of when these activities occurred. The data may be used for land use planning, assessing abandoned mine lands and mine-related environmental impacts, assessing the value of mineral resources from Federal, State and private lands, and mapping mineralized areas and systems for input into the land management process. The data are presented as three groups of layers based on the scale of the source maps. No reconciliation between the data groups was done.

Copyright Text: Datasets were developed by the U.S. Geological Survey Central Mineral and Environmental Resources Science Center (CMERSC) with support from the Bureau of Land Management Solid Minerals Program. Compilation work was completed by USGS student contractors and volunteers Zachary R. King, Stephen Miles, Evan Roberts, Ken Lambert, Megan Horne, Paul Smith, Mollie Doerner, Ward Mitchell, Toby Freyer, Marci Scofield, Rajesh Rajhal, William Schaar, Nicholas Hobson, Mary Sanistevan, and Jennifer McCall; and by USGS personnel Damon Bickerstaff and E.G. Boyce. The authors would also like to thank Alan Coyner of the Nevada Division of Minerals, Sam Hayashi of the California Department of Conservation and Larry Moore and Tracy Fuller of the USGS for their advice and assistance.
