Pen General Discussion, page-52

I would be surprised if the AISC has remained at $31.52 for 2.3 mlbs/yr estimated in the 2018 feasibility study. A simple inflation calculator would make that $36.27 but the inflation we have seen has not been evenly distributed. I have seen Wayne Heili in his interviews pointing out that there has been an inflationary effect on the cost of production although being in the united states at least there shouldn't be any major supply chain issues.
