In summer 2021, the Bureau of Land Management - Nevada (BLM NV) requested that the U.S. Geological Survey Mineral Resources Program (USGS MRP), acting through the Geology, Minerals, Energy, and Geophysics Science Center (GMEGSC) and other collaborating USGS Science Centers, conduct a scoping study to: 1) discover mineral resource data and relevant publications that have been released since the publication of the 2016 USGS Sagebrush Focal Area Mineral Resource Assessment (SaMiRA; Day and others, 2016) for the Nevada portion of the Focal Area, and 2) evaluate whether these data support an update to the assessment for the SFA lands in Nevada. The commodities of interest for this scoping study are: copper, gold, lead, lithium, molybdenum, silver, tungsten, vanadium, zinc, and rare earth elements (REEs). This report is being released as a restricted file federal interagency report (RFFIR). This data release comprises the geospatial files used in the post-2016 assessment. It includes a point shapefile of exploration sites (SaMiRAII_exploration_sites.shp), a point shapefile of reanalyzed NURE geochemical data (SaMiRAII_NURE_reanalyzed.shp), four polygon shapefiles of mine claims and plans and notices for the purpose of plotting density (SaMiRAII_mill_sites_counts.shp, SaMiRAII_placer_claims_counts.shp, SaMiRAII_plans_notices_counts.shp, SaMiRAII_lode_claims_counts.shp), a polygon shapefile of mine claims (SaMiRAII_mine_claims.shp), and a polygon shapefile of plans and notices (SaMiRAII_plans_notices.shp). The SaMiRAII_mine_claims.shp and SaMiRAII_plans_notices.shp shapefiles contain overlapping polygons due to the fact that multiple claims can reside in a single section or quarter section.
