We will have to aggree to disagree. Single mine stocks are pretty basic to value. It all depends on your price and production cost assumptions.

We don't know what the total production costs are yet but my guess (educated) is that it will be closer to 2 bucks than 1. On the price side it's anybodys guess but a reasonable assumption is the down slope will be as inelastic as the upslope, lets see what a 15% pullback in copper demand will do to price. My guess is the same thing it did to price when it was a 15% increase.

There is no way they will produce copper at a buck a pound. Have you seen the logistics chain?
