The Pinto Valley mine property was originally owned by Miami Copper Company in 1909, and transitioned through various owners until the early 1970s when the mine, mill and other infrastructure was constructed by Cities Service Company. The mine has been owned by Newmont, Magma Copper and BHP Billiton. BHP Billiton sold the PVM to Capstone in October 2013. PVM operated continuously from 1974 with the exception of a short shutdown in 1983, and from 1998-2007 and 2008 to 2012. It has operated continuously since the 2012 re-start.
