Phoenix in Maricopa County, Arizona — The American Mountains (Southwest)
The Boras Headframe was the last of the wooden headframes built in the Warren Mining District near Bisbee, Arizona. Erected in 1917, it hoisted over 50,000 tons of copper ores by 1926 when the mine was closed during the Depression. Production resumed in 1938 and continued to 1944. In 1952 the headframe was reconditioned and some of its wood supports were replaced with steel. Until 1975 it served as a ventilation and escape shaft for the interconnecting underground workings of the Dallas and Cole mines. The relocation to Phoenix was completed in 1998.
The shaft served by the Boras Headframe was 1,034 feet deep. The hoist's motor was manufactured by General Electric and rated at 52 horsepower at 550 rpm. Maximum speed of the hoist was 1,200 feet per minute.
The Arizona Heritage Fund and Phelps Dodge Corporation, Inc. provided restoration funding.
Thanks to many organizations who provided labor and materials for the project. Special thanks to Arizona Public Service Company for the use of their crane and its crew.
