Most of us know by now that SCCO will almost certainly have a lower cost per pound. What is interesting to note is that even FCX is able to sell at twice what it costs to produce. Profitable business this copper mining. If or when prices head back up to $3.50 or more profits will soar. One threat I see is the increased use of fiber optics which is SOME applications reduces the need for copper. Another is the increase in home rooftop solar panels that will reduce the need for transmission lines.
