American Bonanza Gold Corp. is pleased to announce that the United States Department of the Interior’s Bureau of Land Management has accepted as complete the Copperstone Mining Plan of Operations and started the National Environmental Policy Act process for the 100% owned Copperstone Gold Project in Arizona. The BLM will be the lead governmental agency with oversight of the permitting for Bonanza’s mining operations. The NEPA process will document and assess cultural and environmental matters at the Copperstone Mine. No NEPA issues are anticipated as the project is totally within the existing area of surface disturbance with no new disturbance planned or expected.
The acceptance of the Mining Plan of Operations by the BLM represents a significant milestone in the advancement of the Copperstone project towards gold mining production.
The Copperstone Gold project produced nearly one-half million ounces of gold between 1987 and 1993. After several years of exploration and resource definition drilling and pre-mining studies, Bonanza is currently planning the re-activation of mining at Copperstone, moving from open pit surface mining of the past to future underground mining of high grade gold mineralization.
