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!

| β Analcime Formula: Na(AlSi2O6) · H2O Localities: |
| β Anthonyite (TL) Formula: Cu(OH,Cl)2 · 3H2O Type Locality: Description: Anthonyite is found in pockets or as encrustations in basalt and occurs as delicate, lavender prisms up to 0.5 mm in length embedded and encrusted by an unidentified waxy green basic copper chloride. Other directly associated minerals are copper, cuprite, paratacamite, and an unidentified blue, isotropic, basic copper chlorite.
Many of the crystals are curved one or more times along the c axis; the plane of curvature is {010} and bending apparently occurs readily on the perfect cleavage on {100} |
