At this site you can read more about the Rudna copper mine in Poland, where they write:
"The Rudna mine is one of the largest deep copper ore mines in the world. Mine construction began in September 1969, and in July 1974 the mine reached 25% of the planned capacity and was officially commissioned for exploitation."
The page has a lot of nice pictures making you understand how large this mine is, but I cannot add them to my site due to copyright.
