Maybe sounds kind of neat. As an alternative theory (albeit a less sexy one) I would think if you're paying $240m for something you'd ask for some sort of due diligence details, it might even be they got the draft report, but that as they wanted more tonnage there actually wasn't any point in pursuing the 4.5Mt scenario anymore? Could it be that simple?
Oh, and no attacks because I'm a non holder please. Great day for AVZ today and more to come in the next few months and years. The monster will awaken gradually.
