275k oz/year at cash costs of US $640, about US 450 mio capex (inital+sus), 5000t/day, at current gold price, mine life about 8 years (UG), Bordon would have pretty good economics (IRR >30%, NAV >500mio).

And dont forget, there is still lots of exploration upside + LGZ + potential higher pog prices+...

Question is, is PRB able to produce at cash costs below US $650???

IMO, entire PRB seems getting better and better.
