I have reviewed the comments by Dr. A. Maest on the Resolution Copper draft environmental impact statement (DEIS) and given them due consideration for producing a response in support of the final EIS (EIS).

This draft technical memorandum has been prepared to summarize hydrogeologic data and provide an assessment of hydrogeologic conditions and water uses in the vicinity of the Whitford, Silver King, and Happy Camp sites (Near West area) for the RCM Tailings Prefeasibility Study (PFS).

The purpose of the Phase I assessment was to conduct non-invasive field investigations to supplement information obtained previously from published data and to plan Phase III investigations involving subsurface exploration drilling and hydrologic testing.

This tech memo has been prepared to summarize results of the Phase II field investigations of the Near West site, conducted in support of RCM's ongoing prefeasibility studies for storage of RCM mine tailings. The purpose of Phase II investigations was to conduct electrical resistivity surveys to assess the potential occurrence of shallow groundwater at the Near West site.
