Largest underground copper mine in the world?

How? Deepest? Most excavation volume/length? Highest production? Need an explanation and a source for that claim.--kelapstick (talk) 17:20, 9 April 2009 (UTC)Reply

Sourced as the "biggest", still no explanation though...--kelapstick (talk) 20:22, 10 April 2009 (UTC)Reply

2,400 km of galleries? If the mine opened up in 1904 and operated continuously for 105 years it would have to get over 62 m (203 ft) per day of development advance...Every day...for over 100 years...Something seems wrong with that number.--kelapstick (talk) 19:27, 9 April 2009 (UTC)Reply
