Johannesburg - DRDGold [JSE:DRD] advised shareholders on Tuesday that a feasibility study has been completed for a R23m upgrade of its Ergo plant to effect an increase in treatment capacity by 300 000 tonnes per month (tpm) to a total of 2.1 million tpm.
The feasibility study envisages refurbishment and re-commissioning of five tanks within the Ergo plant's existing carbon in leach circuit, initially in order to treat the 21 million tonne Van Dyk tailings dam resource.
The project would be funded from additional internal cash flows from the retreatment of the Van Dyk dam and breaks even at a gold price of R384 000 per kilogram. The project is expected to be completed by September 2015.
