CF can discuss SC privately under NDA's and Confidentiality agreements.  There are "tornado charts" and sometimes Monte Carlo analyses that can point to a fairly acurate adjusted NPV that accounts for adjustments to assumptions used like metal prices, fx, capex etc.   They should also have many reports and district maps, and any Teck shared with SCJV partners, and they would have the MIRA report that was never "declassified" and finally it all depends on how convincing you are that there remains vast unsurfaced value.   Simply reading line-by-line your own written slides won't inspire anyone.  JMHO
