During their share buyback, BHP were laying out 25 to 50 million per trading day buying their own shares. $5 billion is a lot of coin but not even a stretch for BHP. They have substantial N. American ops already. I think regardless of how big it becomes, one of the 2 -3 majors will JV with another or two slightly smaller if necessary to take the dominant position. Perhaps look at Ambatovy for a real partnership of expertise, money and marketing power coming together to do what one would difficult and risky. FNX for example could be a smaller partner in such a JV. Just a broad view of how the big guys operate. As logical as CRVD is, they are insular in their approach and likely reluctant to reach for their wallet. BHP took out ANGLO Minerals (potash in Sask) with an all expense paid deal and 25% carried interest. Wouldn't that look nice, a pile of cash and a bundle of long term cash flow.!! It will be a contest.
