An underground copper mine consisting of 11 shafts around Calumet. The Osceola Mining Co. organized in 1873 and worked the Calumet Conglomerate. In 1877, the Osceola Amygdaloid was discovered. In 1879, it merged with the Opechee Mining Co. to form the Osceola Consolidated Mining Co. In 1897, the company opened up the Kearsarge Lode by starting the North and South Kearsarge Mines. In 1909, Calumet & Hecla took control of Osceola and later merged it with its operations in 1923. Calumet & Hecla worked the mine until it closed in 1931. In the 1950's, C&H reopened the mine and worked it until the 1968 labor strike, at which time all C&H operations were closed for good. The best mineral hunting is found at Osceola shafts #3 and #4, where copper crystals and wires are found. Osceola #1 and #2 are also great for copper "skulls", silver crystals, and datolite crystals.
