In my opinion, another significant issue is the existing agreement itself
As someone from CUU management told a poster here, you could drive a truck through it, or words to that ffect
The agrrement itself is full of ambiguities and provides for unrealistic scenarios
For instance it is inconceiveable that Teck would proceed to spend billions of dollars with CUU being in control of the property
There are situations that simply will not hold up and neither party is particularly anxious to test any of it in court
So another factor that informs as to why the BFS would be delayed is that the delivery would start the process on an agreement that is totally inadequate for the project that has evolved since the agreement was originally drawn
