In short; I still trust Elmer's earlier mentioned timeline (perhaps with some delay caused by Teck late delivery of the 2023 program results)

That you can still have trust in Elmer in relation to timelines is well beyond me. Golfyeti's choice of meme applies here: Charlie Brown going to kick the football and Lucy pulling it away. We've been left in the lurch again and again when it comes to meeting deadlines.
