Gunnison (Cu): Excelsior Completes Feasibility Study for Gunnison In-situ Leach Project
12-Dec-2016
Excelsior Mining has competed a feasibility study on the Gunnison copper project in Arizona, US. The project is an in-situ recovery mine using solvent extraction and electrowinning. A staged production profile is planned, starting at 11ktpa of copper cathode, increasing to 34ktpa in year four, and 57ktpa in year seven, with a mine life of 24 years. Initial capital costs of US$46.9m include US$14.6m for the production well field and US$26.8m for upgrades to existing SX/EW facilities at the Johnson Mine Camp and related infrastructure. The permitting process is yet to be completed. Excelsior is aiming to achieve commercial production in 2018.
