Climax mine

The Climax mine, located in Climax, Colorado, United States, is a major molybdenum mine in Lake and Summit counties, Colorado. Shipments from the mine began in 1915. At its highest output, the Climax mine was the largest molybdenum mine in the world, and for many years it supplied three quarters of the world's supply of molybdenum.

After a long shutdown, the Climax mine reopened and resumed molybdenum shipment on May 10, 2012. The mine is owned by Climax Molybdenum Company, a subsidiary of Freeport-McMoRan. Provided by Wikipedia
