Summary

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 deposit types for [...]

Purpose

The polygons representing mineral-resource assessment tracts are suitable for use in Geographic Information Systems (GIS) or other database and geospatial software. The data may be used to derive maps, perform geospatial analyses, or to evaluate mineral-resource potential of locatable minerals in the SFAs. The information is intended to meet the needs of a wide community of users that includes the geoscience and mineral-exploration communities, as well as State and Federal agencies, private industry, and the general public.
