And don't forget that every bit of the uneconomical inferred was used to arrive at the impressive 16% IRR.

I wonder what Schaft Creek's optimized IRR really is with all the low-lying-fruit optimizations, and then go ahead and include also all of Schaft Creek's massive inferred resources in the  calculation of a IRR, you know just like was done for QB2, just for an apples-to-apples IRR comparison?

Let's figure that out!  That would be FUN!
