The point is that what information could be available for CUU to advertise to prospective buyers? Is all the new data and revised estimates under Teck's control?

That has been my concern and why I thought we would be going through a sort of murky period now without knowing really what is going on.

Up until Teck decides to put out a revised Feasibility, or apply for the EA, we could be kept essentially in the dark.

Here's what the JV states regarding a decision to commence a FS. All the work Teck is doing now could be used to re-vamp the FS so this might apply. It appears that the obligation is on CUU to find out the information, rather than on Teck to disclose:

If a Program is approved by the Management Committee to commence a Feasibility Study, the Operator shall keep the non-Operator generally informed of developments.

The non-Operator shall be entitled to second, at its cost, a representative to the Property so that the non-Operator can remain informed so as to be able to participate in Management Committee meetings to review the Feasibility Study and, if a Production Decision is made, to make its election under §14 promptly.
