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.

This map was prepared in cooperation with the Nevada Division of Minerals.MINESThe metal mines shown were active in 2017. Industrial mineral mines that are shown had production in 2017. The gravel operations are those producing more than 100,000 tons annually. Active mines and their locations were determined from a variety of sources, including the "Directory of Mining and Milling Operations" in NBMG’s The Nevada Mineral Industry 2017. The main sources of information that went into creating this directory were the Directory of Nevada Mine Operations, January–December 2017, compiled by the mine inspectors at Nevada Mine Safety and Training, and Major Mines of Nevada 2017, compiled by the Nevada Division of Minerals. These two sources were supplemented with information, especially for 2017, from other sources, such as company reports, LR2000 (BLM), magazine and journal articles, Net Proceeds of Minerals Bulletin, topographic maps, Google Earth, and contact with people in the mining industry. The sites generally represent the main open pit or portal location and are accurate for a display scale of 1:1,000,000 or smaller.GEOTHERMAL PRODUCTION SITESGeothermal site locations are from the “Geothermal Section” in NBMG’s The Nevada Mineral Industry 2017 and information provided by the Nevada Division of Minerals.OIL FIELDSOil field locations are from Assessment of the Potential for Carbon Dioxide Sequestration with Enhanced Oil Recovery in Nevada, 2007, with updated information provided in 2017 by the Nevada Division of Minerals.

Much of the mineral wealth of Nevada is hosted in pre-Tertiary rocks. These rocks are three times more extensive in the subsurface at depths of less than 1 km than they are in surface outcrops, (chapter 2). Because of this, a combined portrayal of the exposed and concealed rocks is crucial to an analysis of Nevada's mineral resources. Plate 4-1 depicts the pre-Tertiary rocks of Nevada in a way specifically designed to support this analysis. The map shows outcrops (dark colors), as well as the inferred distribution (pastel colors) of Precambrian, Paleozoic and Mesozoic rocks, divided into 13 assemblages, beneath Tertiary volcanic and sedimentary rocks, sediments, and alluvium, and Quaternary alluvium and basin fill. The primary source of information for the map is the Geologic Map of Nevada (Stewart and Carlson, 1978), and most contacts within outcrops are taken from it. In some places, new contacts have been drawn, based on more recent studies. Nevada Bureau of Mines and Geology OFR-96-2, Plate 4-1, 1: 1,000K scale.

Weathering and transport of potentially acid generating material (PAGM) at abandoned mines can degrade downstream environments and contaminate water resources. Monitoring the thousands of abandoned mine lands (AMLs) for exposed PAGM using field surveys is time intensive. Here, we explore the use of Remotely Piloted Aerial Systems (RPASs) as a complementary remote sensing platform to map the spatial and temporal changes of PAGM across a mine waste rock pile on an AML. We focus on testing the ability of established supervised and unsupervised classification algorithms to map PAGM on imagery with very high spatial resolution, but low spectral sampling. At the Perry Canyon, NV, USA AML, we carried out six flights over a 29-month period, using a RPAS equipped with a 5-band multispectral sensor measuring in the visible to near infrared (400–1000 nm). We built six different 3 cm resolution orthorectified reflectance maps, and our tests using supervised and unsupervised classifications revealed benefits to each approach. Supervised classification schemes allowed accurate mapping of classes that lacked published spectral libraries, such as acid mine drainage (AMD) and efflorescent mineral salts (EMS). The unsupervised method produced similar maps of PAGM, as compared to supervised schemes, but with little user input. Our classified multi-temporal maps, validated with multiple field and lab-based methods, revealed persistent and slowly growing ‘hotspots’ of jarosite on the mine waste rock pile, whereas EMS exhibit more rapid fluctuations in extent. The mapping methods we detail for a RPAS carrying a broadband multispectral sensor can be applied extensively to AMLs. Our methods show promise to increase the spatial and temporal coverage of accurate maps critical for environmental monitoring and reclamation efforts over AMLs.

Version 10.0 (Alaska, Hawaii and Puerto Rico added) of these data are part of a larger U.S. Geological Survey (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, have been digitized from the 7.5-minute (1:24,000, 1:25,000-scale; and 1:10,000, 1:20,000 and 1:30,000-scale in Puerto Rico only) and the 15-minute (1:48,000 and 1:62,500-scale; 1:63,360-scale in Alaska only) archive of the USGS Historical Topographic Map Collection (HTMC), 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. The compilation of 725,690 point and polygon mine symbols from approximately 106,350 maps across 50 states, the Commonwealth of Puerto Rico (PR) and the District of Columbia (DC) has been completed: Alabama (AL), Alaska (AK), Arizona (AZ), Arkansas (AR), California (CA), Colorado (CO), Connecticut (CT), Delaware (DE), Florida (FL), Georgia (GA), Hawaii (HI), Idaho (ID), Illinois (IL), Indiana (IN), Iowa (IA), Kansas (KS), Kentucky (KY), Louisiana (LA), Maine (ME), Maryland (MD), Massachusetts (MA), Michigan (MI), Minnesota (MN), Mississippi (MS), Missouri (MO), Montana (MT), Nebraska (NE), Nevada (NV), New Hampshire (NH), New Jersey (NJ), New Mexico (NM), New York (NY), North Carolina (NC), North Dakota (ND), Ohio (OH), Oklahoma (OK), Oregon (OR), Pennsylvania (PA), Rhode Island (RI), South Carolina (SC), South Dakota (SD), Tennessee (TN), Texas (TX), Utah (UT), Vermont (VT), Virginia (VA), Washington (WA), West Virginia (WV), Wisconsin (WI), and Wyoming (WY). The process renders not only a more complete picture of exploration and mining in the U.S., but an approximate timeline of when these activities occurred. These 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. These data are presented as three groups of layers based on the scale of the source maps. No reconciliation between the data groups was done.Datasets were developed by the U.S. Geological Survey Geology, Geophysics, and Geochemistry Science Center (GGGSC).

A 1:24,000-scale, full-color geologic map of the Third Butte East 7.5' Quadrangle in White Pine County, Nevada, with one cross sections, and description of 19 units. One of the seven quadrangles in the north Snake Range mapped by Stanford University's Summer Field Program. The GIS work was in support of the U.S. Geological Survey COGEOMAP program. Detailed geologic mapping by Jeffrey Lee, Phillip B. Gans, Elizabeth L. Miller. First edition printing in 1999. The Third Butte East Quad is part of a Cenozoic metamorphic core complex containing the Northern Snalke Range decollement, a low-angle fault. Geologic mapping was supported by the Quadrangle Mapping Program of the Geologic Society of Nevada and Echo Bay Minerals Company, Magma Nevada Mining Company (now BHP), and the Nevada Bureau of Mines and Geology Mining Cooperation Fund. Previous work includes Hose and Blake (1976), a 1:250,000 scale geologic map of White Pine County. Miller and others (1983) and Gans and Miller (1983), based at Stanford University, explained the Cenozoic core complex. Detailed geologic mapping of the Snake Range began in 1981 at scales of 1:12,000 and 1:24,000 (Rowles, 1982; Gans and Miller, 1983; Grier, 1983, 1989; Gans and others, 1985, 1989; Geving, 1987; Lee and others, 1987; Huggins, 1990; Lee, 1990, 1995; Lee and Sutter, 1991).

The purpose of this project was to create quality statewide county digital geologic maps from existing 1:250,000-scale maps in county geologic and mineral resource bulletins published by the Nevada Bureau of Mines and Geology (NBMG).
