30 day of DD will be up soon - so we expecting some news come end of this year (probably more likely early Jan).I don't expect any competing bids until then. And even then It seems that OZL and BHP Olympic Dam are natural fits, so worth more to BHP.
The Australian said as much in a Nov 21st Article.
Mentions a potential $2 FF dividend that would be worth value to some shareholders.
I cant see any reason why they would up to $30 without some outside force (do I hear @gimmegimme activists!)
