if you think suitors are going to wait you are crazy. There is no reason to wait for good holes as the only thing that will accomplish is them paying significantly more. Companies want value not a bidding war. Vale cant sit on assays especially when rumours are flying all over the place like they are and the results are material to Corex. They may not be material to Vale but they are to Corex which makes it impossible to sit on them indefinately. Corex can turn the screws to Vale.
