Ideally, the release of the new RE, the Feasibility and consequently back-in news should all be catalysts to raise our SP.

Assuming TCK doesn't already have a major position, they can push the SP up THEMSELVES by buying shares on the open market (Correct me if I'm wrong?) and that way, the premium becomes "more acceptable" when presented to shareholders.

However, even outside of that - TECK has a share structure with TCK.A and TCK.B. Each share of TCK.A has 100 voting rights, and consequently will make voting on the aquisition easier to do so.

So 3 things we have a few catalysts that should naturally push the SP up, the SP can be manipulated in the positive direction as well as the negative direction by buying at market price all the way up and even outside of the changing of the SP in between now and the buyout - the voting structure of TECK should allow them to push it through, even if shareholders aren't happy short term - long term it benefits them, so they'll do so.
