Link to Build it bigger: South Africa's Mponeng Gold Mine documentary
Documentary Description
Travel to the deepest place on Earth, Johannesburg, South Africa's
Mponeng Gold Mine. South Africa's economy depends on gold, but
recently, productivity has plummeted. Now, Mponeng is fighting back by
digging deeper than man has ever gone, towards an untapped gold reef
worth $10 billion. Setting a new depth record every day, workers blast
through super-heated rock nearly 3 miles down, in the most remote and
dangerous construction site on the planet.
