DescriptionFor the past forty years Arizona has led the United States in copper production, and during the past several years has exceeded all other states in the total combined value of copper, zinc, lead, silver, and gold produced. The first important mining in Arizona was for gold and silver. During the early days, base metals were of little interest in this region, remote from centers of population and lacking in transportation facilities. Development of and continued search for precious metals led to discoveries of copper, lead, and zinc deposits which acquired primary commercial importance during later years. Thus, from the standpoint of value of production, Arizona's leading metal was gold during 1858-1877, silver during 1878-1887,and copper for all the years after 1887. Zinc supplanted gold as the State's second most valuable metal product during 1944-50, and lead took third place over silver during 1945-50. 15 p.
