Alba, you are no doubt aware that this number is derived from the NMC website:
**********Values, before extraction and gross profit margin, range from $1.86 Billion to $3.2 Billion, dependent upon current spot pricing.***********
Whether you agree with it or not, that number is what the company is claiming on its own website. I would think that there would be very serious ramifications to NMC and MS of blatently posting a false value at this point in the game. They must be confident in that number.
