As I understand it, the key factors that make this ore so appealing are the very low impurities, high MgO (apparently very good for use in blast furnaces because the ore is 'self-fluxing') and the fact that it is very easily upgradeable to +70% Fe so you can chuck it straight in the furnace.
And of course it looks like they may have a lot of it close to the required infrastructure (rail, port etc) to exploit it.
All of this suggests that it is very likely to be a commercial play and if so, will likely be a company maker.
