BHP set for the mother of all digs as $30 billion Olympic Dam expansion is approved
Australia on Monday gave environmental approval for BHP Billiton to expand its Olympic Dam mine but set more than 100 environmental conditions on the uranium, copper and gold project.
The $30 billion expansion of the existing Olympic Dam underground operation will create an adjacent open pit mine that would be the worlds biggest. An idea of the olympian effort required to construct the mine and the size of the undertaking is clear from the fact that trucks will haul overburden 24/7 for five to six years just to reach the ore body. The combined operations would mine 72 Mt ore per year and would produce 750,000 tonnes refined copper, 19,000 tonnes uranium oxide, 800,000 gold ounces and 2.9 Moz of silver per year.
