The mine is said to have attracted interest from Magris Resources, a mining investment firm headed by former Barrick Gold CEO Aaron Regent.
Candelaria is one of FCX's biggest mines, last year producing 370M lbs. of copper - up from 270M lbs. in 2012 - and 87K oz. of gold, and completing a $315M desalination plant and pipeline that will supply Candelaria's desert location with water.
