Excelsior is developing a low cost copper project within the copper porphyry belt of Arizona. Based on an initial production rate of 110 million pounds per year and a US$2.75/lb copper price, the Prefeasibility Study indicates a pre-tax NPV (7.5% discount rate) of US$1.24 billion, pre-tax IRR of 59.7% and a payback period of 1.8 years. Total initial capital expenditures (including contingency) are estimated at US$284.84 million with sustaining capital (including an acid plant) of US$602 million and an average life-of-mine direct operating cost of US$0.69/lb. These metrics are amongst the lowest per pound capital and operating costs for copper projects in North America.
