Re: Would it have changed anything to do it before, other than duplicate cost?

I assume that you mean increase cost and not duplicate cost.  In my understanding, one of the problems with our resource estimate is that such a large % is in the Inferred category.  More drilling would allow more of the resources to move to the M&I category.   That is one reason why 40% of the resources are left out of the NPV category.  Is my understanding incorrect?

I was looking at the Teck slides again, it frustrating to me that EVERY other project by Teck uses a copper price of $3.50/lb - why the heck did we use $3.25.   Now, other projects use a lower price for Gold $1,400 and Silver $18.
