Or would they accumulate shares selling some, at the end of each day,,,,, making the price drop day after day.... until there were very few share holders, they could offer a JV to hold every one else at bay, force a NDA and seal off the news...
It would explain the extra shares that the Steads issued.... may not Vale but some other group or entities all trying to get a piece of the claims...
Some one tell me if the diamond field claim was so great and so well known how did the share price get so low before the buyout...?
