If the delay from Teck is legitimate. And they have heard "nothing". Then usually a delay this long with silence is due to high level executive meetings or a BOD meeting for making a decision. I suggest this because from the look of CUU's SP there is no indication that information was leaked. The complete silence indicates only high level discussion would be happening. And since Teck has had all of CUU's information to crunch the BFS numbers for months there isn't much more to analyze.

As Cbew indicated, a delay could come from organizing a partner to buyout CUU. Because if a JV with CUU was in process then they wouldn't be say that they are not in discussions currently.
