I'm sure they will figure out a way to exceed my numbers lolll

But on a more serious note, production should be 24/7, and at $500,000+ per day, they can afford paying for some extra for overtime when required.  Paper Mills are a good example of this - (running 24/7) with only planned shutdowns of a few days per year for maintenance.

This is a rough estimate.  Mini SGA, HP-hematite, scandium, gallium, magnesium oxide, etc. not included (should compensate for a few days down)...
