Sunrise, Wyoming
The earliest mining activity at Sunrise focused on copper rather than iron. During the Hartville Uplift copper boom of the 1880s, Henry T. Miller staked a claim in 1881 on land later occupied by the Sunrise Iron Mine. Copper ore was hauled by wagon to a smelter near Guernsey, and total production between 1881 and 1887 amounted to approximately 250 tons.
