Here's my take on this. A simple backin decision by Teck should not take this long. Teck has had all the info on SC and has been closely working with us since July of last year - almost a year now so a back in decision ( if that is what they want ) should have been decided by now.
Something more is going on. Something much more material imho to justify this delay and which management cannot say anything about until it is completed. The only thing that makes sense in my mind is a complete buyout involving another partner of Teck's choosing. I also believe that if this is the case then all parties involved will want to wrap this up asap as each day goes by cuts into the exploration season. I give this a couple more weeks or sooner to wrap up. Until then, we won't hear anything more from management imo.
