No one really knows. Only six months ago, all the world's experts were saying that Iron Ore will stay below $50 for the next 3 -5 yrs.
None of them have any clue. They just make stuff up on the run to justify their media positions.

IMHO I believe the spot ore price will continue to increase - not due to any particular science, but purely due to the current trend line. It may well be over $100 by early 2017. And at those prices, GBG will be seriously cash flow positive - and the share price could easily be 10c+.
