This study uses ArcGIS to determine suitable locations for storing tailings from the Resolution Copper Mine near Superior, AZ. It analyzes factors like distance from the mine, land use, slope, and environmental areas to create a weighted suitability map. The map highlights areas within 10 miles of the mine, with the most suitable location being within a mile. While the older Pinto Valley copper mine was considered, it is no longer available due to renewed mining operations. The study identifies 10 potential sites that require further review of land acquisition and visibility before a final site is chosen.
