Xstrata holds a 33.75% interest in the company, which operates the Antamina copper-zinc mine in Peru’s Ancash Region, and is represented on its Board and Executive Committee.

In November 2008, Antamina announced a 77% increase to Mineral Reserves to 745 million tonnes following an intensive in pit exploration program. This significant increase to Mineral Reserves was incorporated into the expansion feasibility study, enabling Antamina to approve this expansion to processing capacity and extend the mine life by six years to 2029.

Xstrata Copper Chief Executive Charlie Sartain commented: “This is the third brownfield expansion of an operation involving Xstrata Copper that has been approved in recent months, following the announcements to construct Lomas Bayas II in October and Ernest Henry underground earlier in December.  These three projects provide a firm foundation for Xstrata Copper to implement its business strategy to grow production by 60% to 1.5 million tonnes in 2015.”

Xstrata Zinc Chief Executive Santiago Zaldumbide said: “The zinc production coming from Antamina reinforces the position of Xstrata Zinc as the largest integrated zinc producer in the world.”

The expansion will require the acquisition of new mining equipment, an expansion to the truck workshop and concentrator plant, the construction of a new 55 kilometre electric power transmission line, and enhancements to the current water management and tailings storage systems.

The expansion will create 2,726 jobs in the construction phase and 500 additional permanent positions. Construction will commence in the first quarter of 2010 and the project is scheduled to be commissioned in the fourth quarter of 2012.
