Active mining involved extraction from open pits, underground mines, other types of surface activity, and one brine operation. If active mining at these sites had ceased temporarily or permanently, production continued from leach pads, reprocessing old tailings, or stockpiles. The main sources of information for these mines are Major Mines of Nevada 2023 (Ghiglieri and Patterson, 2024) compiled by the Nevada Division of Minerals and NBMG’s The Nevada Mineral Industry 2023 (Jowitt et al., 2024) as outlined in "Overview" (Jowitt, 2024) "Metals" (Jowitt and Fisher, 2024), and "Industrial Minerals" (Micander, 2024) chapters of the overall report. These two reports were largely compiled from annual status and production reports submitted to the Nevada Division of Minerals. 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 Energy" section (Richards and Lu, 2024) in NBMG’s The Nevada Mineral Industry 2023 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 (LaPointe et al., 2007) with updated information provided in 2023 by the Nevada Division of Minerals. Only currently producing oil fields are shown; these are discussed in detail in the "Oil and Gas" section (Reynolds and Micander, 2024) of the 2023 Mineral Industry report. Oil field symbol locations are based on initial discovery well. More detailed information on the oil fields, individual wells, company contact information, and production can be found in Assessment of the Potential for Carbon Dioxide Sequestration with Enhanced Oil Recovery in Nevada (LaPointe et al., 2007), NBMG’s The Nevada Mineral Industry 2023 (Jowitt et al., 2024), Major Mines of Nevada 2023 (Ghiglieri and Patterson, 2024), Petroleum Data Map of Nevada, 2007 (Garside and Hess, 2007), and the NBMG Subsurface Database Explorer interactive map (NBMG et al., 2020).MINING DISTRICTSNevada mining district locations are from NBMG Report 47, Mining Districts of Nevada (Tingley, 1998).

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 500,000-plus point and polygon mine symbols from approximately 67,000 maps of 22 western states has been completed: Arizona (AZ), Arkansas (AR), California (CA), Colorado (CO), Idaho (ID), Iowa (IA), Kansas (KS), Louisiana (LA), Minnesota (MN), Missouri (MO), Montana (MT), North Dakota (ND), Nebraska (NE), New Mexico (NM), Nevada (NV), Oklahoma (OK), Oregon (OR), South Dakota (SD), Texas (TX), Utah (UT), Washington (WA), and Wyoming (WY). 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.

Site locations and information on this map were obtained from a variety of published and non-published sources with the last updates made in January 2021. All sites shown on this map have had some form of production activity during 2019.This map was prepared in cooperation with the Nevada Division of Minerals.MINESThe mines shown produced in 2019. Active mining involved extraction from open pits, underground mines, some other type of surface activity, and one brine operation. If active mining had ceased temporarily or permanently, production continued from the leach pads, reprocessing old tailings, or stockpiles. The gravel operations are those producing more than 100,000 tons annually. The main sources of information for these mines are the “Directory of Mining and Milling Operations” in NBMG’s The Nevada Mineral Industry 2019 and Major Mines of Nevada 2019 compiled by the Nevada Division of Minerals. These two documents were largely compiled from annual production reports submitted to the Nevada Division of Minerals and supplemented with information from other sources such as company reports, LR2000 (BLM), magazine and journal articles, Nevada Department of Taxation Net Proceeds of Minerals Bulletin, Nevada Mine Safety and Training Directory of Nevada Mine Operations, topographic maps, Google Earth, and contact with people in the mining industry.

Mineral resource occurrence data covering the world, most thoroughly within the U.S. This database contains the records previously provided in the Mineral Resource Data System (MRDS) of USGS and the Mineral Availability System/Mineral Industry Locator System (MAS/MILS) originated in the U.S. Bureau of Mines, which is now part of USGS. The MRDS is a large and complex relational database developed over several decades by hundreds of researchers and reporters. While database records describe mineral resources worldwide, the compilation of information was intended to cover the United States completely, and its coverage of resources in other countries is incomplete. The content of MRDS records was drawn from reports previously published or made available to USGS researchers. Some of those original source materials are no longer available. The information contained in MRDS was intended to reflect the reports used as sources and is current only as of the date of those source reports. Consequently MRDS does not reflect up-to-date changes to the operating status of mines, ownership, land status, production figures and estimates of reserves and resources, or the nature, size, and extent of workings. Information on the geological characteristics of the mineral resource are likely to remain correct, but aspects involving human activity are likely to be out of date.

The .csv table is part of a dataset package that was compiled for use as mineral assessment guidance in the Sagebrush Mineral-Resource Assessment project (SaMiRA). Mineral potential maps from previous mineral-resource assessments which included areas of the SaMiRA project areas were georeferenced. The images were clipped to the extent of the map and all explanatory text, gathered from map explanations or report text, was recorded into this table. This table is to be used in conjunction with the individual georeferenced raster images. It includes the image file name, map title and figure caption when appropriate. The images are also classified according to the legal definition of mineral resources: metallic, non-metallic, leasable non-fuel, leasable fuel, geothermal, paleontological, and saleable.

1:24,000 scale Geologic Map of the Moho Mountain Quadrangle, Nevada. Nevada Bureau of mines Map 74. Detailed geologic mapping by Larry J. Garside in 1982. The Moho Mountain quadrangle lies in the central Excelsior Mountains, an east to southeast trending range whose form is controlled by high angle faults of similar trend. The Excelsior mountains, with adjacent ranges to the north and south, compose a structurally anomalous zone of east to southeast trending faults common to the basin and range physiographic province in extreme western Nevada. This area has been called the Mono Basin-Excelsior Mountains structural zone (Gilbert and Reynolds, 1973; Shae, 1965). Map includes description of 29 geologic units. The GIS work was in support of the U.S. Geological Survey COGEOMAP program. The Geodatabase specifies feature datasets and feature classes, together with feature attributes, subtypes and domains, suitable for the printed geologic map. In addition to basic geology (lithology, contacts and faults, etc.), the maps may include metamorphic overprints, cross-sections, and explanatory legend-graphics such as correlation charts, used to supplement columnar legends. Previous work includes Structural Geology of the Hawthorne and Tonopah Quadrangle, U.S. Geological Survey Professional Paper 216; Geologic Map of the Mina Quadrangle, (Furgeson and others, 1949); Geologic map of the Camp Douglas Quadrangle (Garside, 1979); Geologic map of the Buckskin Range (Hudson and Oriel, 1979); Geology of the Pilot Mountains and vicinity (Nielsen, 1964); Geology of Nevada (Stewart, 1980).

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.

Descriptive information about the images is listed in the All_georef_images_descriptive_information_table.csv file. The georeferenced images were clipped to the extent of the map and all explanatory text, gathered from map explanations or report text was imported into the All_georef_images_descriptive_information_table.csv file. The descriptive data contains the figure caption from the original map, online linkage to the source report when available, source references, and information on the assessed commodities according to the legal definition of mineral resources—metallic, non-metallic, leasable non-fuel, leasable fuel, geothermal, paleontological, and saleable.

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.

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.

This data release consists of a compilation of previously published mineral potential maps that were used for the Sagebrush Mineral-Resource Assessment (SaMiRA) project. This information was used as guides for assessing mineral potential assessment of approximately 10 million acres in Idaho, Montana, Nevada, Utah, and Wyoming. Specifically, the compilation was used to identify the deposit types to be assessed and the deposit models to develop. The data release consists of georeferenced images of mineral potential maps and vector shapefiles of mineral potential tracts. The georeferenced images are presented in two formats: 1) as images within raster mosaic datasets in Esri geodatabases, and 2) as individual tiff images with an accompanying .csv data table. There are four geodatabases containing the raster mosaic datasets, one for each of the four SaMiRA report areas: North-Central Montana; North-Central Idaho; Southwestern and South-Central Wyoming and Bear River Watershed; and Nevada Borderlands. Tract map images are from BLM and Forest Service wilderness study summary reports, along with multiple other mineral potential reports that were done under the USGS CUSMAP program and for USGS assessments of USGS National Forests. The georeferenced images were clipped to the extent of the map and all explanatory text, gathered from map explanations or report text was imported into the raster mosaic dataset database as ‘Footprint’ layer attributes. This data is also included as a .csv table, which can be used in conjunction with the individual georeferenced tiff images. The data compiled into the tables contains the figure caption from the original map, online linkage to the source report when available, and information on the assessed commodities according to the legal definition of mineral resources—metallic, non-metallic, leasable non-fuel, leasable fuel, geothermal, paleontological, and saleable. The shapefiles were compiled from datasets which had different data structure schemes and which used two different types of assessment methodology. The BLM used qualitative categorical and others used the USGS quantitative 3-part form of assessment. The original GIS data was re-formatted so that all of the shapefiles had one of two consistent attribute table structures, one for reports that had quantitative data, and one for reports with qualitative data. A general attribute table structure was created which contained fields for information on the deposit type assessed, assessment rank, type of assessment, and tract name and identifier. For the attribute table of the quantitatively assessed reports which used the USGS 3-part form of assessment, we added additional fields for the deposit model name and number, probabilistic assessment results data, and estimators. We captured the original information as presented but also standardized nomenclature when we could and referred to the report text in some instances in order to fill in missing data into the descriptive data tables.
