Schaft is mentioned several times in the Appendices. As near as I can tell its information that has been presented before, but on slide 105 it looks to be updated with the info from the most recent CUU press release which includes the multi-year permit and the staged development options. I don't recall seeing those before in a Teck presentation but could easily have missed it. Teck would have approved the CUU release so nothing new per se.
