GIS Catalog of Significant Minnesota Minerals and Geologic Datasets

The Minnesota DNR's Lands and Minerals Division, the Minnesota Geological Survey (MGS), and the Natural Resources Research Institute (NRRI) have an obligation to provide for the diversification of the State's mineral economy through long term support of mineral exploration, development, production, and commericialization" (Minn. State. sec. 93.001). One way to support this statute is by providing spatial information regarding Minnesota's ferrous, nonferrous, and industrial mineral resources. Provided on this page are weblinks to download significant Geographic Information Systems (GIS) datasets relevant to Minnesota's minerals resources that can be sorted by subject. This is not intended to be comprehensive list of all the spatial data related to Minnesota minerals and geology. For more information on additional sources, such as: historic mineral projects or research, mineral lease assessment files, geologic mapping, and more please see the additional information web page
