Freeport-McMoRan Inc., one of the world’s largest copper and gold producers, announced an all-cash deal on Monday to sell its controlling interest in copper mining operations in Chile to Canadian base metals producer Lundin Mining Corp. for at least $1.8 billion. Toronto-based Lundin said it could pay as much as $200 million above the stated purchase price.

Phoenix-based Freeport, formerly known as Freeport-McMoRan Copper & Gold, agreed to sell its entire 80 percent stake in the copper mining operation and supporting infrastructure in the Candelaria and nearby Ojos del Salado region of Chile.
