Footprints of southern Arizona copper mines
We get lots of inquiries and one recent one asked about the size of the proposed Rosemont copper mine in the Santa Rita Mtns south of Tucson. AZGS senior geologist compiled a map showing the size of the pits (brown) for the nearby Pima, Twin Buttes, and Sierrita mines, along with that planned for Rosemont.
Tailings piles are shown in red, and dumps in yellow.
The tailings of the 3 existing mines are prominent along Interstate 19 and visible from many areas of Tucson.
