Xstrata Copper Chooses Oniqua Analytics Solution for MRO Equipment Maintenance and Inventory Optimization Across Tintaya Mining Operations in Southern Peru
Xstrata considers continuous improvement of its assets imperative; Tintaya acquired Oniqua Analytics Solution to help fulfill this corporate mandate.

DENVER, CO, October 25, 2011 /24-7PressRelease/ -- Oniqua MRO Analytics (www.oniqua.com), the leading provider of analytics-based MRO solutions for asset-intensive organizations, today announced that Xstrata Copper has chosen Oniqua Analytics Solution (OAS) to optimize its MRO equipment maintenance and inventory management activities across its Tintaya mining operations in southern Peru.

Project planning and implementation of OAS commenced on site at Tintaya in September 2011, and OAS is expected to be in production state for use by maintenance and inventory management groups by May 2012. Xstrata Copper and Zinc at Mt Isa, Queensland has been an Oniqua customer since 2008.

"The significant operational benefits achieved from Oniqua at the Mt. Isa operation drove Xstrata to evaluate OAS for deployment at its Tintaya operation in southern Peru," stated Lindsay Clarke, President of the Americas, Oniqua. "With the goal of determining the potential economic and process benefits that could be achieved by deploying OAS at Tintaya, our team of MRO optimization experts conducted an onsite Business Value Assessment in December 2010. The assessment, which uncovered significant opportunities for improvement across equipment and asset maintenance as well as inventory management, led to the acquisition of OAS by Xstrata Tintaya in September of this year."

Xstrata considers the continuous improvement of its assets imperative, including safety performance, environmental management and contribution to communities and stakeholders. To that end, Xstrata's strategy is to mandate that each commodity business, such as Xstrata's Copper and Zinc and Tintaya operations, improve the net present value of its underlying business. Xstrata Tintaya acquired and is implementing OAS to help fulfill this corporate mandate of continuous improvement.

Xstrata Copper is the fourth largest global copper producer with attributable mined production in 2010 of 913,469 tons of copper in cathodes and concentrates. The company is also one of the world's largest producers of smelter and refined copper, including from third party materials.
