Big picture - Why invest in 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.

Project Highlights

North Star Probable Mineral Reserve of 4.5 billion pounds (782 million short tons grading 0.29% Cu) contained within a Measured & Indicated Resource of 4.9 billion pounds (873 million short tons grading 0.29% Cu).  Mineral Resources and Reserves are at a 0.05% cut-off.
