A geochemical characterization was completed as part of the Pre-Feasibility Study for Resolution Copper Mining, LLC. The geochemical characterization of overburden, development rock, and ore will support the Arizona Department of Environmental Quality (ADEQ) Aquifer Protection Permit (APP) Program and the Plan of Operations, which taken together will be used to support the Environmental Impact Statement (EIS) prepared for the project. Additionally, the data generated was used to construct a geochemical model to assess the impacts of block cave mining to groundwater during operations and following closure.
