Ecrevissicon,

what else did you expect?  as long as Teck and CF are negotiating about SC, Teck will not put SC high on their Copper Plan.  And of course they are in negotiation, otherwise the delivery of the 2019 report would never have taken so long.  Both parties have been negotiating the content of this report.  And now the point of final appreciation has been reached.  And that requires the PEA. to quote the words of CF ( i received in an email) " Because there has been such significant optimizations from the 2013 FS, there is still certain geotechnical information that would be necessary in order to be used in a FS, as such we are doing a PEA" 

And more important ". This is still a significant milestone for us as it will set an independent valuation benchmark that the CF directors can use in making any decision regarding maximizing shareholder value with SC, and Teck cant' argue to much with this new valuation" 

So, they're still on speaking terms and during this period Teck won't change the ranking on the Copperplan. JMO
