Teck's third quarter results are out on Thursday, which could put the timing of the JV meeting into next week. One analyst, Barnes at TD, thinks Teck could report asset impairment on their coal reserves if they move to a more realistic price deck:

I expect Teck to offset this issue by booking other resources/reserves elsewhere, like SC. While it's never been stated, the optimization studies have to lead to something. They are not a make work project. I think those studies will result in a Technical Report, which Teck typically does to support the booking of reserves and posts on SEDAR.
