Spatial databases of the Humboldt Basin mineral resource assessment, northern Nevada

This report describes the origin, generation, and format of tract map databases
for deposit types that accompany the metallic mineral resource assessment for
the Humboldt River Basin, northern Nevada. The deposit types include
pluton-related polymetallic, sedimentary rock-hosted Au-Ag, and epithermal
Au-Ag. The tract maps constitute only part of the assessment, which also
includes new research and data for northern Nevada, discussions on land
classification, and interpretation of the assessment maps. The purpose of the
assessment was to identify areas that may have a greater favorability for
undiscovered metallic mineral deposits, provide analysis of the
mineral-resource favorability, and present the assessment of the Humboldt River
basin and adjacent areas in a digital format using a Geographic Information
System (GIS).
