Mud, Prospekt is the go to girl on this, I myself have never laid eyes on anything stating a 4 year clause....you will not find one on anything to do with CUU. The clause is purportedly in the agreement between Teck and Liard, when Teck exercise their option CUU acquires 78% of Liard.....hence where the clause comes in to play. Since Liard is a private company the documentation may be hard to find....but accordingly it is there. Rogue,
