Question, will the BFS be a surprise one way or another to CUU Insiders or Tck. I would guess within a small % they have all worked out these numbers. ??

I think this reply from Elmer (below) will answer your question, and if you want my opinion, if Teck di dnot intend to back in they would have said so a long time ago, they have spent time analizing Schaft Creek: :

The company has a relationship with Teck, Canada's largest diversified mining company, can you explain the significance of this relationship to our readers?

Teck has an earn-back right pursuant to the Option agreement entered into in 2002. We have been working with the senior technical people from Teck since early 2010 when we announced that we were proceeding to complete a feasibility study on Schaft Creek. The purpose of engaging Teck early on in the process of completing the feasibility study was to have their input into the feasibility study that is required to allow Teck to make their decision as to their participation in the Schaft Creek project. Teck’s experience in operating open pit mines of the size of that contemplated at Schaft Creek is valuable information that helps makes the feasibility study a realistic and practical study in the contexts of developing the deposit.
