Calvin,

QUALITY

we're back to pennies per pound valuations again?  that's what you use for inferred only deposits or perhaps on PEA's.  I even got ExplorationGuy to give up on such an unfair valuation approach for Schaft Creek. We're a 7-years optimized Bankable Feasibility Study mega-project in a safe poly-metallic mining district wth massive optionality. 

QUANTITY

Plus, you do know, right?, that anything published on QB2 has this little itty-bitty asterisk on it... All ROI is based on using everything, including MI and Inferred resources at QB2...imagine how much more MI and inferred Schaft Creek would have if the operator played fair and did resource-expansion drilling over the last seven years?? LOL 

ROI

So you would have to totally readjust your Schaft Creek ROI assumption to convert the waste-not-waste, optimizations over 7 years, etc etc and of course include at a minimum ALL the recorded MI and inferred in order to have an apples to apples comparison with QB2
