"Silver has not been accounted for (which a lot of people may have missed in their analysis), and indeed maybe some factions believe it will be left entirely out of the feasibility."

My understanding, based on my conversations with CUU in January, is that silver will be left out of the FS. However, they don't see that as a problem since TECK is fully aware of the silver potential. The mine will be set up to take care of silver, so whether it is or is not in the FS makes no diffeence.
