Note: Total water consumed, total water withdrawn, and ocean water used for processing and cooling decreased significantly in 2016 due to the divestiture of our Batu Hijau operation in Indonesia. Total water recycled increased due to the divestiture of Batu Hijau and the addition of our Cripple Creek & Victor (CC&V) operation.
