This data layer identifies natural iron ore mine and ore reserve properties in the Cuyuna Range. It was developed by the Natural Resources Research Institute (NRRI). The properties comprises the areal extents of the surface land parcels attributable to each underground natural iron ore mine on the Cuyuna Range. These lands encompass permitted mining-related activities including mining, processing and stockpiling. Also included are defined ore reserve properties (see NRRI report NRRI/TR-2015/54). The possible extents of underground mining for those mines in which underground mapping was incomplete or non-existent in areas, or where maps of underground workings had not been found are delimited. This information is important for locating associated data for the recovery of mine-associated stockpiles and for denoting defined ore reserves for further investigation and development.
