MEXICO — Construction of the first sulphide process line at the Penasquito gold project in Zacatecas is complete and commissioning has begun, says Vancouver-based owner Goldcorp. The company reports it has a 230,000-tonne stockpile ready for milling. The Line 1 feeders and conveyor systems are complete, the SAG and two ball mills are being commissioned, and the lead and zinc flotation circuits are ready to go.

Construction of the second sulphide process line is underway in preparation for completion in Q3 2010. It, too, will include a SAG and two ball mills.
Goldcorp says each of the two sulphide circuits will have a designed throughput of 50,000 t/d. When the high-pressure grinding roll circuit is completed in Q4 2010, the mill will have a capacity of 130,000 t/d. Annual output will average 500,000 oz of gold, 30 million oz of silver and more than 400 million lb of zinc over each of the project's estimated 22 years of life.
