Oh come on web! Your post is filled with so many incorrect assumptions I do not even know where to begin.
First off, it has been stated by management that they want this done early. I know that doesn't mean it will be the case but it was stated publically in the RE conference call that it was there intention. After sticking to their RE release date, I hazard to guess that it will be earlier than the end of summer.
Secondly, it has been determined that the clock starts when Teck receives the BFS NR not when it is officially filed with Sedar.
Please see this as it was already discussed:
