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”,
