Final Resolution Copper Tailings Geochemical Characterization Data Summary Report
This report presents final results for the geochemical characterization study conducted on tailings produced for metallurgical testing as part of the Resolution Copper Mining, LLC (RCML) Pre- Feasibility Study (PFS). This study is evaluating the potential for the RCML tailings to become acidic or leach metals, and is required to support the Arizona Department of Environmental Quality (ADEQ) Aquifer Protection Permit (APP) Program and the Mine Plan of Operations review and subsequent NEPA analysis being prepared for the project. This data summary report summarizes laboratory testing procedures and test results that were completed on concentrate produced during mineral processing, feedstock material, and metallurgical testing (rougher, cleaner, and whole) tailings produced from the lock cycle float tests.
