A new dawn at Sunrise Dam

SEMITRAILERS running underground and reverse circulation drilling underground are two of the biggest changes for a Western Australian underground gold operation.

The Sandvik 60t haulers used at Sunrise Dam could find themselves replaced by semitrailers.

Anglogold Ashanti has already put in place a major upgrade to the Sunrise Dam processing plant and it is planning big changes to get the mine up to a 4 million tonne per annum throughput.

The RC drilling approach has been brought in to provide better sampling and cheaper, quicker drilling. While it is widely used in surface operation it has not really been applied underground.

Sunrise Dam was once one of the nation's top gold producers, peaking at 600,000 ounces. Of course in those days it was an open cut operation.

Anglogold Ashanti wants to crank production at the mine back up to 300,000oz to 350,000oz a year.

The biggest change to the process plant has been the addition of a fine grind and flotation circuit.
