Madison Mine (Copper Creek; National Lead Company;

Underground mining began at the Madison Mine in 1847, at which time copper was the main metal of interest. This mining ended in 1849 but the mine reopened during the period 1860-1863 during which time lead and copper were mined. Several different companies owned the Madison Mine between 1901 and 1961 and removed lead, copper, cobalt and nickel ores.
