Phase I Hydrogeologic Field Investigations, Near West Tailings Site, Pinal County, Arizona
This tech memo has been prepared to summarize results of the Phase I hydrogeologic assessment of the Near West site, conducted by Montgomery & Associates in support of RCM's ongoing prefeasibility studies for storage of RCM mine tailings. 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. Phase II investigations were conducted concurrently with Phase I investigations and involved electrical resistivity surveys conducted by HydroGeophysics Inc. to further characterize the subsurface in support of planning for Phase III investigations.
