Abstract
The Anaconda Company, an organization of mining people, enters a new world of copper production as it brings on stream its recently constructed Twin Buttes operation some 25 miles south of Tucson, Ariz. Twin Buttes comprises the largest earth-moving task performed in the history of mining. Some people liken this job to moving enough earth and rock to complete the famed Aswan High Dam in Egypt. In all, some 236 million tons of overburden and rock were removed from over the ore deposit.
