William Ascarza Special to the Arizona Daily Star Many mountain ranges near Tucson have significantly contributed to Arizona's mining history. These include the Sierrita, Silver Bell, Patagonia and Santa Rita Mountains, which have a similar geological origin.
People are also reading… Other mines in and nearby the Sierrita Mountains include the Copper Glance Mine in the Twin Buttes Mining district, which had its own railroad spur for ore transport; along with the Senator Morgan Mine, worked for copper since the late 1870s. Mining in the area is extensive and began with the discovery of high-grade oxidized copper ore at the Old Boot Mine in 1865. The arrival of the Southern Pacific Railroad 15 miles to the southwest in 1881 heightened development, with a 30-ton-per-day furnace built onsite by the Huachuca Mining and Smelting Co.
Dropping copper prices also forced ASARCO to suspend operations at the nearby Silverbell Mine. The mine was developed by ASARCO in 1951, including two ore bodies, El Tiro Pit and Oxide Pit, separated by two and one-half miles. Copper production continues to the present.
