The story
The Bulga Coal Complex was originally started by BHP Limited as the Saxonvale Mine in 1982. It was later brought by Elders Resources in 1988, and then sold to Oakbridge Limited in 1989. Shortly after Oakbridge Limited purchased the complex, Japan's Nippon Oil bought part of the mine and renamed it Bulga Coal. Glencore (through Enex Resources Limited) bought a stake in the mine 2000. Glencore's stake was purchased by Xstrata plc when it floated on the LSE.
