Excelsior Mining “The Copper Solution Company” is a mineral exploration and development company that is advancing the Gunnison Copper Project in Cochise County, Arizona. The project is a fully-permitted, advanced staged, low cost, environmentally friendly in-situ recovery copper extraction project. The Feasibility Study projected an after-tax Net Present Value of US$ 807 million and an Internal Rate of Return of 40% using a US$ 2.75 per pound copper price and a 7.5% discount rate. Excelsior is on schedule to produce first copper before the end of 2019; which would make the Gunnison Copper Project the next new copper producer in the United States.
