Correction on my error: I see now that the price being used is for lb of vanadium pentoxide ($7), not elemental vanadium; Thanks Texas for pointing that out to me.
I went back to the presentation, at around min 19 and it shows that the company could pay off the $450 mil capital costs within 1.8 years, then every year thereafter they could "net" 330 mil dollars. Just using 100 mil shares, that $3.3 dollars earnings/share over potentially 20+ years for the mine.
