RE: TAMIt's the March '08 Presentation. Just cut and paste the link rather than clicking on it, or go to the website and visit the Investor's tab. The Presentation on the main page is for the old Oct presentation.
It's a lot better than the last one, but still leaves a bit to be desired. Very strange to compare market caps and share counts - it's meaningless data absent knowing the size of the individual company's resources? I always want to see valuation tied back to resources to give the relative valuation.
EV/lb of zinc equivalent is probably the best comparison metric for preproduction plays, although grade needs to be considered. Of course, with TAM's 60MM tonnes of resource, with some extremely high grade deposits, it blows away the supposed competition.
