AR has a fantastic chart, but I've been concentrating on the beat up names - I think they have more bang for the buck potential right now.
As for CXX, you are right - there is no proof that it's bottomed. I simply believe that the market has switched to risk-on, so I give the benefit of the doubt to any junior that has apparently stopped going down and not made a new low in the last month or so. Still, I wouldn't buy it until it starts to tick up on increased volume - there are plenty of juniors doing just that.
