BONANZA EXPLORATIONS, INC. COPPERSTONE MINE PROJECT LA PAZ COUNTY, ARIZONA

Environmental Assessment DOI-BLM-AZ-C020-2018-0041-EA

INTRODUCTION/BACKGROUND:
The Copperstone operation was originally operated as an open pit mine by Cyprus Mining Corp (Freeport) from 1987 to 1992 and consisted of an open pit, ore crushing facility, cyanide heap leaching and vat leaching gold recovery facilities, a tailings impoundment, a reclaim solution pond, waste rock dumps, and inert construction debris solid waste disposal facilities. Reported production at the proposed Project was 447,000 ounces of gold from 5,880,017 tons of ore grading 0.086 ounces/ton of gold. A mine closure plan was implemented in 1995 and completed in accordance with the requirements prevailing Mining Plan of Operations (MPO) and Aquifer Protection Permit. This site also includes an ongoing wetlands treatment project overseen and operated by Freeport.

In 2011 American Bonanza constructed a 450 tons per day (tpd) floatation mill on site and in 2012 started underground mining from two declines that were previously developed in the bottom of the open pit. American Bonanza’s mining focused on the D zone which is to the north of the open pit. From January 2012 to July 2013 American Bonanza produced approximately 16,900 oz of gold from 163,000 t of ore grading 0.104 oz/t of gold. American Bonanza maintained control of the Copperstone Project until Kerr’s acquisition in June of 2014.
