All very interesting, and should do EXS no harm
I doubt XST will get IRN for only $1 but it's a start and at least the Xstrata Copper Team are finally starting to play the M&A game, having largely left it to their Coal & Nickel colleagues of late.
As Noellyn has suggested, Lion's role in all of this may well ultimately be a factor in the context of EXS
