Heh, I just lost the almost complete post I wrote!! So, I'll start again.
For now I plan to just sit & wait for my gut is telling me that a richer offer will be forthcoming. Based on nothing more than the Bahuerachi deposit sits in NA and that is worth a premium over otehr regions.
In any case, nothing to lose by being patient. My shares are in my RRSP and when bought, I had a $5 target exit in mind. Not likely to see that but 1.60 is quite a bit away from it so am not so willing to give them up just yet.
