As I stated in an earlier reply I only calculated the upper portion of the potash horizon. As soon as I'm ready with my calculation per hole including the other horizons I'll let you know ;-)
Keep in mind the AAA will have significantly lower costs so the value of their resources is higher and that is what you take to the bank.
Plus, some of the M+I resources for Sask companies will never see the light of day because the cost to recover it is prohibitive. Whereas a lot of Allana's is close enough to the surface that it can be recovered at a reasonable cost.
