FWIW, I think it very unlikely that Codelco will step out of Chile and take an active role in a new mine in a different country as they have plenty of projects on their local plate already. On the other hand, Codelco is a welcome visitor in Ecuador and a long-standing partner to the Chinese metals industry; an advisory role is more probable. To hear Xstrata is sniffing around is interesting and logical, but the one you have to pay attention to is Tongling. For one thing, it doesn't really matter which Chinese company is the ostensible front, as all the recent Chinese purchases of LatAm mining projects have been funded by the state.
But hearing the word Tongling also ties in with the fact that Corriente head honcho Ken Shannon and other CTQ bigwigs were very recently spotted dining (well, lunching to be precise) in a high class Quito restaurant with a large party of Chinese guests. A good time was being had by all, and Shannon picked up the bill. I'm sure it can be filed under "essential investor relations expenses."

Buen provecho Ken, and good luck with the investor roadshow in New York at the end of the month ;-)
