RE:net present valueThe NII 43-101 od 2014 had an NPV of USD510M @ 8% (Table 22-10). and USD678M @ 5%.
For a more recent NPV estimate,you would have to assume: a). an improved mineal resource, b). higher sale value, c). somewhat offset by increase mine building and production costs and, d). improved discount rate. If I were to guess (and that's what I'm doing), I would say put me down for USD 1B.. Pinkanja has always been a good project.....
