Data Source and Calculation

The Department of Mines, Minerals and Energy has estimated that there are 4,000 orphaned mineral mine sites based on historical records of mineral mining activity in the state. Orphaned lands are those areas disturbed by the mining of all minerals, except coal, which were not required by law to be reclaimed or have not been reclaimed. The total number of inventoried mineral mine sites is taken from the orphaned mined land information system. The percentage is calculated from these data.
