An underground copper mine consisting of seven incline shafts near the community of Centennial Heights, just north of Calumet. The Schoolcraft Mining Company was organized in 1863 and worked the Calumet Conglomerate in a small scale operation until it went bankrupt in 1873. In 1876, the Centennial Mining Company organized on the previously owned Schoolcraft property and worked the Osceola Amygdaloid until 1896, at which time the company re-organized as the Centennial Copper Company. Work was discontinued on the Calumet Conglomerate and the Osceola Amygdaloid and two new incline shafts were driven on the Kearsarge Amygdaloid. In 1923, Calumet and Hecla took control of the mine and operated it until 1931 when it closed. In 1944, shaft No. 2 was reopened and operated until 1966 when the mine closed for good. Before Calumet and Hecla took control, the Centennial Mine produced approximately 37 million pounds of refined copper. The mine today offers the collector a wide range of minerals. A visit to No. 3 or No. 6 can produce copper "skulls" and an occasional greenstone (Chlorastrolite). Shafts Nos. 1 and 2 can yield copper crystals, silver, datolite, and incredible quartz/epidote crystals. A note about Nos. 1 and 2; the county owns these piles and uses them for their activities. At last check these piles were almost gone!
