Secure stable copper / moly supply, creating sustainable value for our owners and stakeholders: 3,4 mtf Copper in concentrate 449 ktf Copper cathodes 95 kt Molybdenum Final Remarks It´s been eight years of an on-going effort in an environment of extreme conditions with thousands of people working with a common objective: To design and built the Caserones project according to the highest social, environmental, safety, engineering and construction standards. It is an endeavour committed to a long term relationship with our stakeholders community, workers, suppliers, contractors and owners - with reserves that will allow us to produce copper and molybdenum for at least 28 years through an efficient and sustainable operation. Successful transfer of a high altitude wetland THANKS
