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.

Isaac Taft Stoddard was an American businessman. Born in the State of New York, he started in the insurance industry there and in Connecticut before turning his attention to copper mining in the Arizona Territory. He owned either personally or with investors several mines in Yavapai County, built the first smelter in that part of the state, and secured the investment of over $1,000,000 in the mines to increase production. Another business venture was assisting out-of-territory corporations in incorporating in the territory. He served as the twelfth Secretary of the Arizona Territory from 1902 to 1904, but was forced to resign amid criticism over conflict between this business and his position as Secretary. He continued in mining and incorporating, and later became president of a telephone and telegraph company.
