In order to get a 8B valuation for Schaft Creek, you need around 1.2B of net cashflow year after year.

I disagree.  Show your math.   let me guess, you are using botched FS numbers, pre-optimization, and applying NPV8 on a completely disrisked poly-metalic enviro-benign, inidginous supported, multi-generational mine in a safe jurisdiction...LOL.

Whoever, you are...you are talking way above you pay grade right now.  Maybe you better just step down and get your boss Shiela to post her thoughts directly.
