Teck would not be wise to jump into an agreement without ensuring an authorized, viable EA is first in-hand. If the EA is not scheduled for completion until 4th quarter and Teck wishes to proceed on a deal with CUU prior to its receipt, it would be wise for it to have a solid contingency clause that gives it an out if the EA ultimately prevents mining from proceeding.
It isn't possible for Teck to change the terms of its earn-back options to give them a contingency to get an out. After the BFS is released they have only 120 days and a one-time only option to decide how much to earn-back. They can't control the timing or change the terms.
