The Croesus Gold Mine is now part of the western edge of the Superpit. The Croesus Proprietary was a London based company which developed the mine from the late 1890's. The gold was found at depth in the calc-schist, for a long time a rock thought to carry no gold on the Golden Mile. Gold was described as fine and frosting the matrix.
Operations appeared to go continuously until a lack of labour during the Great War years forced its closure. Charles Edwin Bond died when he fell down a shaft in 1914.
In 1913, the Oroya Links company from neighbouring Brownhill lease controls the mine, but sell it in 1928 to the North Kalgurli (1912) Limited.
In January 1929, the South Kalgurli Consolidated took a 10 year tribute over the mine from North Kalgurli (1912) Limited. The shaft had reached a depth of 1050 feet. Their operations continued beyond the 10 years, with a new plant and steel headframe erected in 1947. The mine was still operational in the early 1950's when the sources stop.
