IMO, I personally think the Teck agreement is not going to matter and there will be no back in.
Think about it in Teck's position
-CUU is able to present a FS where Schaft Creek is worth $3 billion+ (I based it on the old numbers of $2.8).
-Teck is interested in acquiring this deposit.
-If FS is out, Teck would have to elect how much to back in. When market finds out how much of Schaft Creek CUU owns after the back in, institutions or investors would flood back in after calculating CUU worth. This presents a risk to Teck that if CUU SP ends up appreciating to a more speculative number, Teck would have to pay more to convice CUU shareholders sell the rest of the company to them.
-It's probably Teck's best interest to discuss acquiring CUU in the dark. Look your highest price was $2.75. What if it's a premium over $X.
