I guess what i am really asking is does Cuu unsiders and TCK have a close estimate of what the cost of getting the copper out of the ground with the credits from the other metals. With the lower price of moly, maybe the exclusion of silver and higher cut off grades of copper, can we still be negative cost or will we be surprised to see a plus cost for the copper? and if so how high would the cost/lb of copper end up being.
