RE:RE:RE:RE:Double From Here?There are a couple of risks here, 1) copper price, 2) converting M&I resources to reserves. If you look at the assumptions capstone used the payback will be less than four years. At 3.15 copper, and cash flows of 200m for first 5 years, and 150m over 25 year life the IRR is 27%. NPV is about 1 billion, with these assumptions (which include 345 million in sustaining capital), total cash flow 3.6 billion, discounted cash flow 1.6 billion. This is giant low grade deposit, so margins are thin (thinner), with higher risks. If you think copper will stay above $3 for next 5-10 years, then a pretty good deal.
