Think a little longer term...4 moz for around 50m US is pretty good in that location. It gives GCM three mines once the Juby is setup. A lot of room for expansion drilling.
GCM has total control over Caldas and it's not running anywhere. That greenstone gold belt is very prolific so a good position to be in. GCM is producing oodles of cash. They are expanding and all these deals recently are setting them up to be a very significant player in the gold market..
The share price is in a holding pattern and Sprott is just adjusting his investments. The guy has fingers in so many pots and is always looking for further plays. Just hold your horses this thing is going up in a big way. The Columbia mine is allowing them to make these plans and it's doing a good job.
If you are not happy sell... There are plenty of buyers still accumalating. Gold is only going one way and so is GCM.
