By 2015 the first loaded gas tankers are due to leave both sides of Australia for China, Japan and Korea.

Gorgon involves the world’s first commercial CO2 geosequestration operation, while coal seam gas has never before been processed into LNG for export. Despite such ambitious innovation and their scale, these projects haven’t really excited the public imagination.

This will likely change in coming months as the approval process for BHP Billiton’s proposed expansion of its Olympic Dam mine in South Australia’s outback cranks towards a final decision next year. The centrepiece of the project is a simple emphatic image – a big hole. Over 11 years the removal of a billion tonnes of overburden will create Australia’s biggest opencut mine, alongside our largest underground mine.

From this pit they expect to increase annual production at least threefold to 750,000 tonnes of copper, 14,500 tonnes of uranium oxide, 700,000 ounces of gold and 2.1 million ounces of silver.
