Rebirth of the Sacaton Copper Mine, Casa Grande, Arizona?
Elim Mining recently purchased the Sacaton open pit mine near Casa Grande, Arizona, with the hope of reopening the mine. The chief ore is porphyry copper, but Elim hopes to garner some gold, silver, and molybdenum, too.
Elim Mining’s decision to revisit Sacaton may have been prompted by voluminous data - geologic, geophysical, and geochemical - gleaned from dozens of Sacaton Mine-related documents served from the Arizona Geological Survey Mining Data site (ex., Richard, ca. 1970).
The Sacaton mine was operated by ASARCO from April 1974 to March 1984. When producing, the mine employed 400 people and churned out 11,000 tons per day.
