Cadia sees mill breakdown

Newcrest’s Cadia mine’s SAG mill has been shut down following motor issues.

On Saturday a problem was detected with the motor on concentrator 1 SAG mill, Newcrest said in a company statement.

The issue is as yet unknown, the miner said, and as such the mill has been shut down while engineers work to determine the repairs required.

It is understood that this primary mill processes more than two thirds of all throughput at the mine.

Despite this setback, the concentrator 2 SAG mill is continuing to operate at full capacity, with excess capacity stockpiled on the surface until it can be processed.

The 1 SAG mill will remain offline for an as yet unknown period of time, most likely lowering production and potentially putting Newcrest’s full year guidance in jeopardy.

When BHP’s Olympic Dam mill went down due to an electrical fault it took nearly six months before it was online again, and caused an impairment at the site.
