Welcome to the public website for the Pinto Valley Mine Environmental Impact Statement (EIS). This site provides information on the Pinto Valley Mine EIS and public involvement.
The Pinto Valley Mine is an existing open pit copper and molybdenum mine located approximately 8 miles west of Miami, Arizona in Gila County. Pinto Valley Mining Corp. is proposing to expand mining activities onto the Tonto National Forest, extend the mine life to 2039, and to consolidate previous and ongoing authorizations for the mine. The proposed project would result in an estimated 1,011 acres of new disturbance (245 acres on Tonto National Forest land and 766 acres on private land owned by Pinto Valley Mining Corp.). The EIS will evaluate and disclose the potential environmental effects from approval of the Mining Plan of Operations for activities on the Tonto National Forest. The EIS also will evaluate any necessary amendments to the Tonto National Forest Land and Resource Management Plan.
The Tonto National Forest issued a Notice of Intent to prepare the Pinto Valley Mine Environmental Impact Statement (EIS) on March 28, 2017, and the scoping period closed on April 27, 2017. A Draft-Final Scoping and Issues Report recently was completed and summarizes the scoping process for the Pinto Valley Mine EIS. The report also outlines key issues for analysis. It is available for review by clicking here.
