NCU really?
You are comparing Apples to Solar systems... NCU: Assuming the Base Case of US$3.15 copper, US$1,200 gold and US$18 silver, the Integrated Project generates Life-of-Mine ("LOM") after-tax net cash flow of US$2.5 billion, NPV@ 5% of US$1.1 billion, an after-tax IRR of 15.6% with 4.7 year payback; We absolutely kill this as an investment by quantum leaps in so many ways.
