Locatable Mineral Assessment Tracts for the U.S. Geological Survey Sagebrush Mineral-Resource Assessment Project
The polygon (vector) feature class represents locatable mineral resource assessment tracts (tracts of land) associated with the Department of the Interior (DOI) Sagebrush Focal Areas (SFAs) in Montana, Wyoming and Utah, central Idaho, and the Oregon-Nevada-Idaho border area. The mineral-resources tracts are geographic areas that were assessed by the USGS and were determined to be geologically favorable for a deposit type of interest to a depth of 1 kilometer. Qualitative assessment methods outlined by the Bureau of Land Management (BLM) were used to develop tract boundaries and to assign a level of mineral-resource potential and certainty to each tract. The general process included (1) identifying possible mineral...
USMIN Mineral-Resource Data for the U.S. Geological Survey Sagebrush Mineral-Resource Assessment Project
The point and polygon layers within this geodatabase represent locations of mineral occurrences, mines, mining and mineral districts and sites of active mineral exploration within or near the Department of the Interior (DOI) Sagebrush Focal Areas in Montana, Wyoming and Utah, central Idaho, and the Oregon-Nevada-Idaho border area. The data were compiled by the U.S. Geological Survey (USGS) Mineral Deposit Database project (USMIN) to provide mineral resource information for use in the USGS Sagebrush Mineral Resource Assessment (SaMiRA). This assessment was conducted for the Bureau of Land Management (BLM) and evaluated the mineral resource potential of approximately 10 million acres of Federal lands identified as...

These photographs were mostly taken from the Arizona Department of Mines and Mineral Resources (ADMMR) Mining collection, records on mineral resource exploration and mining in Arizona from late 1800s to the early 2000s. Photographs principally relate to a mineral locality reported in the Arizona Mineral Industry Location System. Photographs titled "ADMMR" document the history of the Arizona Department of Mines and Mineral Resources, making up a little over 10 percent of the collection. Items were arranged alphabetically by prints and negatives, then slides and lastly Polaroids. The hyphenated number at the end of each title refers to the old numbering system employed by our dedicated volunteers and should not be...
This inventory describes photos taken by A. L. Flagg during his travels as a mining engineer over the period 1905 to 1955 and they capture life in developing western North America.
