This technical memo summarizes the evaluation of the model construction and approach for the groundwater model used to evaluate future groundwater conditions at and surrounding the proposed Resolution Copper panel cave mine. The groundwater model does not consider impacts from the future tailings facility or water supply pumping over 5 miles distant from the site.

This internal draft memorandum provides a summary of mining-induced seismicity as it may relate to the Resolution Copper Project block-caving mine currently proposed near Superior, Arizona. This document includes a brief discussion of the causes, mechanisms, and occurrences of induced seismicity, particularly as it relates to the proposed mine and possible impacts from the proposed mining activities.
