RE:Nickel Is The New Gold Says Elon Musk. Supply Vs Demand Grade is only part of the equation. A resource with a 2X grade and a 1Y recovery is economically equivalent to one with a 1X grade and a 2Y recovery. Yes, Decar has a much lower grade than sulphide deposits, but it also has a recovery of ~90%, as compared to the 55-65% reported by those alternatives.
There is also the matter of processing cost and carbon emissions. Awaruite doesn't require smelting, which costs about ~1/3 of the selling price, in addition to contributing ~2/3 of the total carbon emissions attributable to conventional sulphide deposits.
ESG aside, grade is only one variable that influences the bottom line, and FPX's NPV is the best of any in its peer group, even though it uses relatively conservative assumptions.
Not that ESG should be discounted, because the lack of smelting combined with the actual work (rather than just talk) on carbon sequestration indicates that FPX's project will be significantly cleaner than any alternative.
Good luck with your alternate play. Feel free to post it here; these boards are far from cluttered.
