Best measured value for 68 elements in 175,856 samples were combined statewide. Data are provided in shapefile format.

This report describes compilation and evaluation results of data from the USGS global mineral assessment including new descriptive mineral-deposit and grade and tonnage models and spatial databases for deposits and occurrences, ore bodies and open pits.

With extensive geological and mineral resource information here, we estimated a mean of 25 undiscovered deposits of this type in this area, with a mean estimate of 95 million metric tons of copper.

Geochemical analyses of Cretaceous igneous intrusions in order to establish the geologic framework for world-class mineral deposits of the Butte district

Delineated areas of the world that are geologically permissive for the occurrence of undiscovered selected nonfuel mineral resources together with estimates of the quantity and quality of the resources

This study area encompasses the greatest sediment-hosted copper-cobalt province in the world, containing 152 million metric tons of copper in greater than 80 deposits.

Georeferenced images depicting the concentration of 68 chemical elements in the near-surface materials (sediments and soils).

This study delineated permissive areas for undiscovered porphyry copper deposits, compiled a database of known deposits and significant prospects, estimated undiscovered deposits within those areas and made probabilistic estimates of their metal content.

Locatable mineral resource assessment tracts (tracts of land) associated with the Department of the Interior (DOI) Sagebrush Focal Areas in Montana, Wyoming and Utah, central Idaho, and the Oregon-Nevada-Idaho border area. Data are provided in Esri file geodatabase and shapefile formats.
