In Arizona, copper mining has been a major industry since the 19th century. In 2007, Arizona was the leading copper-producing state in the country, producing 750 thousand metric tons of copper, valued at $5.54 billion. Arizona's copper production was 60% of the total for the United States. Copper mining also produces gold and silver as byproducts. Byproduct molybdenum from copper mining makes Arizona the nation's second-largest producer of that metal. Although copper mineralization was found by the earliest Spanish explorers of Arizona, the territory was remote, and copper could seldom be profitably mined and shipped. Early Spanish, Mexican, and American prospectors searched for gold and silver, and ignored copper. It was not until the completion of the Southern Pacific Railroad in 1876 that copper became broadly economic to mine and ship to market.
The El Paso and Southwestern Railroad began in 1888 as the Arizona and South Eastern Railroad, a short line serving copper mines in southern Arizona. Over the next few decades, it grew into a 1200-mile system that stretched from Tucumcari, New Mexico, southward to El Paso, Texas, and westward to Tucson, Arizona, with several branch lines, including one to Nacozari, Mexico. The railroad was bought by the Southern Pacific Railroad in 1924 and fully merged into its parent company in 1955. The EP&SW was a major link in the transcontinental route of the Golden State Limited.

At the town's peak near the end of the 19th century, Harshaw's mines were among Arizona's highest producers of ore, with the largest mine, the Hermosa, yielding approximately $365,455 in bullion over a four-month period in 1880.
