About Superior, AZ

The first claims here were staked in 1875, and the Silver Queen Mining Company was organized in 1880. With depth, rich copper ore was discovered, but early efforts to mine copper failed. Boyce Thompson bought the old Silver Queen mine in 1910, and by 1912, the Magma Copper Company was in production. A narrow gauge railroad connecting to the Phoenix and Eastern Railroad was built in 1915, and later converted to standard gauge. A smelter was built in 1924.
