Iron Valley is a lot closer to Rio's rail than the Koodaideri
deposits - maybe it's Rio buying again? BHP adjoins Iron Valley too.
But my money's on Fortescue. I don't think RIO was in a trading halt before buying Koodaideri so there's no reason FMG should be either. Could also be a joint venture not a sale?
We'll all know on Monday but this can only be excellent news for the share price.
