Blackcop, I would be surprised to see another offer actually. DML is not in the lowest quartile, infact its probably in the third. So for this alone it will not attract the big guys, ie BHP etc.
They have not ramped up fully yet and so there may still be some surprises. Have a look at ALB if you want a rough comparison.
Hopefully Im wrong, but look at the facts and leave the emotions behind.
