The Riverina South Gold Mine borders the Riverina Station homestead. A number of shafts are found to 500 metres south, which is the British Lion lease, which was taken over by the Riverina syndicate in 1899.
The Riverina deposit was discovered by W. Ferminger in 1896 for a syndicate based in Hay NSW. The syndicate developed the Riverina mine, while Ferminger developed the Riverina South.
The reef is a continuation of the one in the Riverina lease to the north. The reef gradually trends eastwards. By 1902 it had been worked to 130 feet depth. There is a second reef on the eastern boundary of the lease, as a small north-south striking reef, containing in 1902 a shaft down to 50 feet.
A 5 head battery and 4 cyanide vats were erected. The mine was worked on and off until 1915, producing 16 900 tonnes of ore worth 53 500 pounds.
In 1915, the Riverina South Gold Mining Company was floated in Melbourne to acquire an option over the mine. Significant development and mining then took place until 1921.
In 1927, the Riverina Blocks company was formed, which un-watered the Riverina South shaft and sampled the deposit. Alfred Forbes was the driving force behind this and had raised sufficient capital to sample the mine, but was seeking more to work it. No information was found of active mining by the company.
