"No one has given me a reason why Teck couldn't put aside 5% of the intended buy out offer amount and use it to buy CUU on the market first, just until the desired price range is maintained for a bit. I wonder what $50 Million to $100 Million dollars chasing CUU would do to the share price? LOL"

That is not likely going to happen. Teck is involved closely with CUU on the BFS (in fact they have to approve the NR), they would, by definition, be insiders and acquiring CUU shares will be considered insider trading. JMO
