St Barbara is focused on strong margin gold operations.  The Gwalia Underground mine at Leonora Operations is the Company's cornerstone asset, with 2.0 million ounces of gold in reserves.  Also at Leonora the King of the Hills mine commenced production in June 2011 

The Simberi gold mine is in New Ireland, the eastern most province in Papua New Guinea and started production in February 2008.  During 2012 the plant is being expanded to 3.5 million tonnes per year with installation of a SAG mill to lift gold output towards a run rate of 100,000 ounces per annum. This will make it a significant contributor to PNG’s economy and its community, with significant further exploration potential around the mine.

Gold Ridge mine, on the island of Guadalcanal in the Solomon Islands, has operated intermittently since 1998 and has undergone a $150 million refurbishment which will increase capacity to around 100,000 ounces per annum in 2013.  There remain significant exploration opportunities around the existing ore bodies.

The Company is operating in proximity to nearby townships with established infrastructure, giving it a significant advantage over newer operations.  In addition to treatment plants, infrastructure includes airstrips, power generation, accommodation, water and social infrastructure. 

The Company encourages employees to live locally but has an active fly-in/fly-out workforce.
