First, here's some examples that you have posted with no explanation that always manage to add a bunch of value:

I see plenty of opportunities left to increase the PEA value by another 50% to 100% with the 2021 Program.

That could mean close to 500M in additional Copper Fox cash flow.

seems like this PEA possibly segregated the Liard royalties, which is worth close to an additional 300M for our 25%.

The FMV will be determined by the information in the PEA and not by wishful thinking. Unless you have done economic analysis in a commercial or development team for a major resource company then your posts are just conjecture with no basis in reality. 

Second, QB2 is no comparison for SC. There's an established mine with QB1, almost 9 billion lbs in 2P reserves, an additional 53 billion lbs cu in the M&I&I resources, a 100 year estimated mine life and the fact that Sumitomo is not buying the NPV, they are buying the copper. Why not use Galore? It's right next door and just entering the PFS stage. My opinion is just as worthless as yours if it's not backed up by real world examples. If you really want to take the red pill to see how far down the rabbit hole goes then take a look at this:

Take a look at slide 20 for a realistic comparison of NPV valuations at the PEA stage. Then look at the PEA economics which are better than SC. Then take a look at the market cap for WRN, which has a 100% of a project containing more copper and gold than SC.
