I am happy to hold until the cash costs to June 2013 come out. If they are down around $2 and dropping I'll be happy. If they are still a lot higher and not dropping it will likely be time to bail out.
Management have done pretty well doing all the work to get Boseto into production over the last few years, and I will give them the chance to prove that their recent announcements on cash costs are accurate.
The other interesting aspect of this takeover is that most of the institutional investors must have rejected the takeover price, as Cathay has only picked up another 2-3% of the Company shares since December.

6 months can be a long time in the life of a developing copper producer.
