The Fosterville Mine is a high-grade, low cost underground gold mine, located 20km from the town of Bendigo, Australia. It is the largest gold producer in the state of Victoria, Australia. The Fosterville Mine features extensive district scale exploration potential and low cost production. The mine is located in an area with well-developed infrastructure and is accessible by paved roads. Fosterville’s ore is processed at the mine’s ~830,000 tonnes per year mill. The processing path for the ore involves crushing and grinding followed by flotation, bacterial oxidation and CIL circuits. The modern sulphide treatment plant is one of the world's leading BIOX systems and has achieved record recoveries. Fosterville commenced production in April 2005 and poured its one millionth ounce of gold in January 2016, representing an important milestone of safe and sustainable production at the mine.
