Do you know? The world’s deepest gold mine is Mponeng, South Africa.
It is 2.5 miles deep, the length of ten Empire State Buildings. Mponeng is a gold mine in South Africa’s Gauteng area.
It spreads over four kilometres below the surface and is considered to be single of the most substantial gold mines in the world.
It is also now the world’s deepest mine from ground level. The journey from the surface to the bottom of the mine takes over an hour.
Over 5400 metric tonnes of rock are mined from Mponeng each day.
At a cost of $19.4 per gm of gold, the mine only needs to extract 10 gms of gold per ton excavated to continue profitably.
