Copper prices have been recovering after a slump in 2016, helped in part by demand from top metals consumer China, but remain well below their 2011 peak.

The deal will also include some shareholder loans in the Minera Panama unit and LS-Nikko's stake in a joint venture with Korea Resources Corp.

First Quantum said it would pay for the deal over a five year period.
