Other gold stocks have dropped just as much. It is not specific to IGR. Whether the cone thingy is at 10mm or 12mm has little to do with the IGR SP movement over the medium term IMO.
If you have not noticed, the POG is technically in the balance. It is all to do with that. If the POG goes up, IGR will sky rocket IMO.
30-33c would be excellent buying here if you can get it.
