It is already been stated by the Company that the flotation/caustic approach is very cost effective. The 43-101 provided some rough numbers and they were, if memory serves, below $2K per tonne. Aubrey, for those who have called to ask, is stating that the optimization they are doing could very well reduce the cost. The optimization is more tweaking than re-inventing. Even at $8500 selling price and $2000 cost per tonne the metrics here are staggering.

I am actually quite confident that the cost will be in line with what the 43-101 mentioned. I would think though, given the nature of the grahite market, the PEA will have various scenarios - different prices, different annual production, different costs even. That would seem appropriate given there is no fixed price to hang one's hat on like the Gold price.
