Big Picture – A Deep Dive Examination of Excelsior Mining Corp

Excelsior Mining Corp Snapshot

Full production rate is planned at ~57,000 tonnes or 125 million pounds of copper per year, which is ramped up through cash flow from an initial ~12,000 tonnes or 25 million pounds operation, processed through their SX-EW processing plant. 

Based on using a life of mine US$2.75/lb copper price, the Feasibility Study indicates a post-tax NPV (7.5% discount rate) of US$807 million, and an IRR of 40% with a payback period of initial capital of 2.8 years. Initial capital expenditures for the 25 million pound operation (including 15% contingency) are estimated at US$46.9 million with an average life-of-mine direct operating cost of US$0.65/lb. These metrics are amongst the lowest per pound capital and operating costs for copper projects in North America.
