Doesn't really matter to me what comes first, exploitation of Nickel/Gold/PGMs or Chromite because as soon as infrastructure becomes financial feasible to put in ALL those metals in the ground become more valuable.

Moving bulk by train is more economical than by road although initial capital investment higher. Nice thing about rail is that tarrifs get set by the tonne and who ever uses it pays for it. That 'tarrif' also includes a healthy amount towards recovery of capital investment. Chromite could provide the necessary tonnage to make the whole area economic for rail infrastructure since Nickel while valuable still hasn't indicated enough tonnage to provide payback over a lengthy period.

I would not be in the least surprised to find ourselves with several 'partners' down the road. One would be the Railroad, another the extraction/mining and then the smelting/processor in Sudbury/Thunderbay. My guess is that this is Cliffs 'plan'.
