Popis: The Lucin mining district is in the northern third of the Pilot Range of western Utah and eastern Nevada. The district has produced since 1870 over three million dollars of low grade copper and iron ore primarily of malachite, chrysocolla, goethite and limonite. Mining operations reached a high point in the early nineteen hundreds but because of high percentrages of alumina and silica, milling and metallurgical difficulties forced the gradual decrease in production until in 1955, operations were abandoned.
