20. Final Remarks
Successful transfer of a high altitude wetland
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.
