History

The Tropicana deposit was discovered in 2005 and, together with the nearby Havana deposit, discovered in 2006, constitutes the last major Australian gold discovery.

The area is seen as a new major Australian gold province, previously untouched due to its remoteness, and dubbed the "Tropicana Gold Belt".

Project

A pre-feasibility study carried out by AngloGold Ashanti in 2007-08 showed the mine would cost A$500 million to $540m and could produce up to 430,000 ounces of gold a year.

The projects location at the western edge of the remote Great Victoria Desert

 constitutes one of the biggest barriers for the project, with 220 km of road having to be built to be able to access the future mine and a 40 megawatt power station being required to supply it with electricity.

The project is estimated at a initial mine life of 10 years, now extended to 15, with an annual production of around 330,000 to 400,000 ounces of gold and an overall production of 3.6 million ounces.

The decision for the mine to go ahead is expected in 2010 while mining is scheduled to begin in 2013. AngloGold Ashanti sold its 33% stake in the Boddington Gold Mine

 in early 2009 to Newmont, a move seen by analysts as the "logical thing" in order to be able to afford the expenditure of the Tropicana development.

The open pit at the mine is scheduled to be up to 6 km long, 1.5 km wide and up to 400 m deep.

The development of the mine was approved by boards of the two companies on 11 December 2010. Construction is to start in June 2011, while the first gold pour is scheduled for December 2013. The cost of the project is estimated to be in excess of A$700 million.

Environmental impact

The future mine site is expected to include the clearing of 3440ha of vegetation and is likely to emit up to 330,000 tonnes of carbon dioxide
