I listened to it again and what stood out to me was John's point about the possibility of high-grade underground ore being accessed from about mid-life of the china starter pit. That should have a positive impact on the NPV if it starts around 5-6 years. For the PFS, I'm expecting an increased lom, lower strip ratio, and hopefully access to some of that high grade ore with significantly more of it in the indicated category. All upside for the financials in the upcoming PFS.
