Yes this is correct according to my phone call.  Elmer has been going back and forth meeting with JV and the 3rd party to go over completed portions of the optimization studies....we wait on Teck for these studies to all be complete and agreed upon - "only one chance to get this right"

if they are produced while pp is open it can potentially cause another delay, but that is unlikely 

completed Op studies will either may bring about the need for a new resource estimate
