As a caveat in using any 'numbers 'from VB, as opposed to valuation methodology, the differences in some major parameters need to be pointed out:(these will be front and centre in a valuation model)

  1) NOT appears very high grade, multi mineral with PGM's, therefore substantially lower processing cost if open pit (per $ extracted)

 2) Big international mineral demand growth, reflects in a highly competitive demand for world class deposits = lower risk discounts

3)time to develop and exploit should be less with McF . With risk discounted present valuing, that might equate to 10-12% per earlier year for McF.(less PV discounting)

Ultimately, getting a fix on these favorable factors will be second only to the grades and tonnage. But they predict to me a substantial net PV increase to McF values over the VB model.
