Sprott said why he sold on his weekly wrap up

Not really buying the reasons TBH. He said he didn't like the streaming deal with Wheaton (ie. losing all the silver) and he didn't like the Caldas gold note dilution. These are both Caldas financing issues, so the idea you sell your GCM shares because of it is likely not the whole story if you ask me.
