Abstract
Claims were staked in the Alta basin by the mid 1870s and silver ore was being shipped by 1878. The Alta Mine, one of the area's largest producers, was being developed by 1881. Although most of the area mines operated intermittently, a few of the larger mines were steady producers. The Gold King Mine was the first mine operated by an electrical plant using AC current. By the late 1940s the district was inactive.
