"if Xtrata were to take out FWR's chomium on the cheap, then they could probably get NOT's nickel much cheaper."

No I do not agree with the last part of that sentence.
I would say that they would get NOT's chromite much cheaper. As for the nickel mine it would cost much more separately and they probably would not bother.

Too many of you here place a disproportional premium on the chromite ( possibly due to owning FWR shares?) imo, and devalue the nickel, copper etc., while I say that the chromite is less valuable than the simple numerical in-ground value and the nickel ore is more valuable than the simple in-ground. It boils down to marketability and not just crunching the numbers.
