DMO Mining Permits Industrial Minerals Underground (Active)

This dataset identifies the boundaries of active and recently active mining permits issued by the PADEP for the extraction of non-coal industrial minerals in Pennsylvania. The information in this dataset was gathered from digitizing the permit area extent shown on historic and modern mine maps. The maps to these mines are stored at many various public and private locations throughout the Commonwealth. The maps have been scanned to create a digital archive, and georeferenced to their approximate location for use in a geographic information system (GIS). The dataset is continuously updated as new maps are processed.
