Statement of Significance (as of designation - November 13, 1966):
Developed in 1904, this is the first open pit copper mine in the world, and the largest. It continues to yield a high percentage of all American copper.

In 2008, the mine is 2-1/2 miles across at the top and 3/4 of a mile deep, the largest man-made excavation on earth.

The resource remains an active mining operation. The company is expanding mine operations--including a pit expansion--that will extend the life of the mine until 2017. By 2015, the mine will be at least 500 feet deeper than it is in 2008.
