You know what, there is no way you can be THAT STUPID.  You are here to simply disrupt intelligent conversation, and to tell lies to frustrate and demoralize Copper Fox Shareholders who are simply looking for a fair deal on a project we took all the risk on and served to TECK on a silver plater a BFS.  In return we got nothing but ABUSE from Teck Resources.  And now you.
