19. Mission
What we want to achieve ....
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

20. 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
