RE:the big question is
You have to know that Dia looses it's stake in diagras anyway if they don't participate in exploration. They have no money and left the diamond business anyway. They had no choice.
So they can be happy to get 300k. That amount is meaningless to the worth of diagras. Much better than a court case, for Dia and Add.
Nobody invests 300K in a project if no work is planed. I guess we will know soon.
