The Jaguar/Bentley operation is 60km north of Leonora and consists of the copper-zinc-silver underground mines and milling operation.
The Jaguar deposit was discovered in 2002 and the Bentley site was found six years later.
Ore is processed onsite at the Jaguar concentrator, which can produce both a copper and zinc concentrate.
The copper concentrate also contains significant silver and small gold credits. The concentrate is transported via truck to the concentrate shed at the Port of Geraldton where it is shipped to metal smelters.
In the June quarter of 2013, the operation milled 111,647t at 10.8 per cent of zinc, 1.7 per cent of copper and 145g/t of silver for 10,683t of zinc and 1620t of copper metal in concentrate.
It was a record quarterly mill throughput and concentrate production rate for the mine. Long hole stoping ore tonnes increased to an 82 per cent production rate.
