World’s largest copper mine moves underground [Images]

After close to a century of operation, Chile's Chuquicamata mine, the world's largest open cut copper mine, is moving underground.

Works are well underway to move the Codelco operation from open cut to underground.

The project's first phase will reportedly cost over $2 billion to complete and will see the miner access estimated copper ore reserves of about 1.7 billion tonnes.
