This technical memorandum was prepared to document groundwater transport modeling and results for TSF Alternative 5—Peg Leg.

Technical memorandum evaluating potential drawdown impacts from groundwater pumping to supply water for the proposed Resolution Copper mine.

This memorandum was written to document model construction and results of steady-state groundwater flow modeling (Model) of the proposed Near West Tailings Storage Facility (TSF).

Summary of reconnaissance investigations at the Skunk Camp site, an alternative site for a future tailings storage facility (TSF).

This catalog has been prepared to summarize available information for selected springs and seeps in the Upper Queen Creek and Devils Canyon watersheds. The springs and seeps included in this catalog were selected based on proximity to planned facilities as proposed by Resolution Copper for the Resolution mine project. Version 2.0.

This report presents a water budget for all watersheds and groundwater systems within the projected impact area for the panel-cave underground mining project proposed by Resolution Copper.

Summary of reconnaissance investigations at the Peg Leg site, an alternative site for a future tailings storage facility (TSF).

Fourteen sites were studied to provide baseline technical hydrologic monitoring in the Oak Flat area within or adjacent to the projected disturbance zone of the proposed RC block cave mine.

This report summarizes results of drilling, construction, and testing of hydrologic test wells DS16-01 through DS17-17, and piezometers DS17-18 and DS17-19 at the Near West Site. The wells were drilled to provide hydrogeologic characterization of the groundwater system in the vicinity of the proposed tailings storage facility currently planned by Resolution Copper northwest of Superior, Arizona. Results of the drilling program will be used as baseline information to support the development of the Resolution Copper Environmental Impact Statement (EIS).
