Most people don't know how
hard it is to mine gold. You'll
get to see it now. This is a fun
show, with a look at South
Africa's most important
business, as the country with
the largest natural gold deposits
on Earth. It's amazing process,

that I'd never seen from
beginning to end before.

In South Africa's North West
Province is one of the world's
most intense engineering feats
and the deepest occupyable spot
on the planet. It's the Mponeng
is a gold mine. Located over
4 km (2.5 mi) below the surface,
the trip from the surface to the
bottom of the mine takes over
an hour, at 40 miles per hour in
elevators which can carry up to
120 miners at a time, the biggest
elevators in the world.

The temperature at that depth
66°C (151°F), and the mine
pumps slurry ice underground to
cool the shafts' air to below 30°C
(86°F).

The mine needs to recover only
10 grams of gold per ton
excavated to remain profitable,
at a price of $19.4 per gram of
gold extracted.

The mine encompasses at least
two gold reefs, with the deepest,
one meter thick - at a surprisingly
low concentration. By the end,
you'll understand why gold is so
precious.
