The numbers will be released by copper fox in an NR that will be signed off by TECK prior to its release. The numbers will not surface the new SC value just by themselves; they will need to be incorporated in an updated report, like RE or PEA, which will result in an updated NPV.

Next time TECK will release an official value for SC is probably the release of PFS, which could be a couple of years away; copper fox will not hang around for that. Elmer will likely update RE/PEA and then start the ball rolling with TECK/Newmont and finalize a sale. All of the above imo :)
