Comments received on the DEIS, including those from the U.S. Environmental Protection Agency, questioned the appropriateness of stopping the analysis at these locations and not assessing impacts further downstream, particularly to community water supplies. In response, Section 3.7.2 of the FEIS has been modified to discuss further downstream impacts.

The purpose of our current Project Memorandum is to provide specific responses to those review comments directed to LCI. Specifically, BGC’s comments to LCI pertain to LCI report “Site‐Specific Seismic Hazard Analysis and Development of Time Histories for Resolution Copper’s Proposed Skunk Camp Tailings Storage Facility, Southern Arizona”,

The purpose of this memorandum is to summarize the available information supporting this approach, some considerations in managing pyrite tailings, the available guidance and best practice, other examples of subaqueous tailings disposal, and to generally comment on the applicability for this Project.

Managing regional aquifer systems within the arid southwestern U.S. basins requires an understanding of the extent to which aquifer recharge and withdrawal impacts the systems, both spatially and temporally.

Following the Resolution Copper Groundwater Modeling Workgroup held on January 16th, SWCA forwarded an email communication detailing the questions from the U.S. EPA on January 25th (email provided in Appendix A). This memo provides responses to EPA’s comments and supporting information.

Some copper deposits can have up to a dozen strategic and critical mineral and materials as co- products, making copper a gateway mineral to these rare elements.
