Centennial Mine

Mining Partially Demolished Michigan United States

History: 

An underground copper mine consisting of 7 incline shafts near the community of Centennial, just north of Calumet.

The Schoolcraft Mining Co. 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 Co. 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 Co. Work was discontiued on the Calumet Cgl. and the Osceola Amyg. 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 #2 was reopened and operated until 1966 when the mine closed for good.

Before C&H took control, the Centennial Mine produced approx, 37 million lbs. of refined copper.

Personal Commentary: 

The old headframe on this site, #1, was incredibly rickety. I had no interest in even attempting to climb the steps, or enter the structure that appeared ready to collapse at any moment.

The largest building on the site was sealed up tight and afforded no access.

The shaft, however, appeared oddly open.

The #2 site was close by, but appeared to have been re-purposed as a current business, and I left it alone.
