Yes, I thought of that too Chappy but if this is the case Teck could easily have made their decision months ago that they are backin for X% with another partner ( if that is the case ) and then announce the details to be worked out later. Under our agreement with Teck, they have to make a back in decision within the 120 days.
Teck has always honoured their agreements with juniors within the timelimits specified ( see their past examples with other juniors ) even if the juniors did not. The only thing that would supercede this agreement imo is if something more material and bigger is being contemplated like a total buyout. Anyways, these are just my thoughts and opinions. Nevertheless, I think we will find out soon enough.
