Are you not looking at just one metal at a time and judging on basis of each of those? Note that while nickel is the source of the majority of the $s, we have a sizable contribution from copper and PMs. I say very economic because the combined profits are several times operating costs. Think return on investment. Again you may be looking at just the tonnage and assuming that it is border line in size therefore borderline economical. I say it is large enough to be worth while developing even in that northern region. Finally, it will not be of the size that we know now, it will be bigger, all drilling and discovering not being complete.
