With over 3,000 kilometres of underground drifts, it is reported as "the world's biggest underground copper mine", and is the largest of Codelco's operations.El Teniente mine is undergoing, since 2011, a structural project called New Mine Level. It consists of expanding the mine deeper into the hill at 1,880 meters above sea level. The project is being carried out without interrupting the operation of El Teniente Division.
