World's Deepest Mines Highlight Risks of New Gold Rush

This is kinda neat:

The ambitious new mining projects are "ultra-deep" mines with shafts that are deeper than 2.2 miles (3.5 kilometers) in the ground, where temperatures rise well over a hundred degrees Fahrenheit (55 degrees Celsius) and rock shatters like glass.

Rocketing gold prices have made ultra-deep mining more attractive in South Africa, the world's largest gold producer.

Recently, gold hit a 28-year high: 770 U.S. dollars per ounce. That means deposits that were once too impure or too deep to mine are now worth prospecting.
