sandfire too expensive?

Surely SFR based on the high copper price being used in calculations would be too expensive.Its top or approaching top of the copper market possibly.Small correction and mark it down as another top of market purchase.What about another metal or mineral,i have always liked companies to be somewhat diversified to ride out the peaks and troughs? Failing that put the 1.5B on shocking in the cup though you may have trouble getting the bet laid:-)
