Ann: ZRL Copper Project Approved (EIS) , page-25

Just looking at the latest presentation and saw that the resource is large, but is a very low grade, so my question is, has it been mentioned as to how economical this project really is? With such a low grade, one would assume it'd be pushing the boundaries.. Anyone with a bit more knowledge on this one that could shed some light would be terrific. After all, you lot aren't in on this one if you didn't think it had a shot at going anywhere.
