I may get done for cross promoting here but have a look at STB. Not Iron ore but Fertiliser and a similar story to SDL. Huge resource and still finding more, Just too big of a project to do it all by themselves and will need someone with deep pockets for railway lines etc, is in North East Africa rather than West Africa so has plenty of soverign risk and the share price has dropped a long way from its highs.
