It will be a milestone event for CUU when Teck books reserves for SC. Did you know Teck booked reserves for Galore Creek on the basis of a PFS, which is a lower level analysis than a FS? Booking reserves followed by an announcement of filing the EA would be significant events we could expect in the near term. Teck is still waiting (2 years) for the QB1 permits to be approved before submitting the SEIA on QB2. They need to see that there are no significant environmental objections before committing capital to a project. I expect the same approach for developing SC.
