Borneo Resource Investments Ltd. announced it is actively mining its Ratatotok South gold property and has successfully completed its first full scale production test run. Ratatotok South was acquired by Borneo in December 2013, through its subsidiary PT Puncak Kalabat. This is the company's second producing gold mine.

Borneo commenced mining gold at its first producing mine, Talawaan, in June of 2013. The 8.5 hectare Ratatotok South property is located in the middle of a well-established gold reef structure. It is adjacent to Ratatotok Southeast, which Borneo acquired, also through its subsidiary PT Puncak Kalabat, in January 2014 and Ratatotok, which was acquired in March of 2013.
