St Barbara is an Australian based, ASX listed gold producer and explorer. St Barbara’s assets include the Leonora Operations in Western Australia, the Simberi mine in Papua New Guinea and the Gold Ridge mine in the Solomon Islands. It has Mineral Resources of over 13 million ounces of contained gold including Ore Reserves of over 5 million ounces of contained gold, as well as an extensive landholding comprising granted tenements and tenement applications in Australia and the western Pacific.
The Leonora Operations include the Gwalia 1.2 Mtpa processing plant and the Gwalia Underground mine and the King of the Hills mine, as well as nearby development opportunities. St Barbara’s Gwalia gold mine was commissioned in October 2008 and is the cornerstone asset for St Barbara with an indicative mine life exceeding nine years and high grade mineralisation below the current reserves. King of the Hills commenced production in June 2011 with an expected mine life of 4 years and is expected to produce 55,000 to 60,000 ounces per annum.
The Simberi gold mine is on SImberi Island in Papua New Guinea and started production in February 2008. In 2013 the plant was expanded to 3.5 million tonnes per year with installation of a SAG mill with the objective to lift gold output towards a run rate of 100,000 ounces per annum. The Simberi mine is 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 was refurbished between 2010 and 2013. There remain significant exploration opportunities around the existing ore bodies.
