Yes.  Thanks for your hlep.  I didn't realize that sustaining cost was part of the Total costs.  Also I didn't know how to use the cuEq line.   The main issue that I was that I based costs on just the Copper production not the cuEq production.   So, I now i get your $4.7B NPV value. 

Now I can play with my own numbers. :) 

For example, if use $1,600 gold (closer to average of the past 2 years), and $18.50 Silver.... I get a $5.3 NPV value.  

Or I use $1,600 gold (closer to average of the past 2 years), and $18.50 Silver....
I get a $5.3 NPV value.  

Or based on current spot prices: Copper $3.60, Gold $1,850, Silver $25.40, and Moly $11.
I get a $7.0 NPV value. 

Just fun to play with the numbers...
