Resolution Copper Company commissioned Golder and Associates to establish a program for the collection of baseline surface water data near the future RCC mine and associated facilities. The intended uses of the data are primarily to support and EIS, develop a sound conceptual site model as a basis for predicting future impacts, and document current conditions as a baseline for judging future impacts.
This report summarizes the meteorological, nitrogen dioxide (NO2), sulfur dioxide (SO2), ozone (O3), and particulate matter (PM) data collected at the Resolution Copper Project near Superior, Arizona for the third quarter, July 1-September 30, 2013.
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.
Three motion-sensitive cameras besides springs within a study area along Devils Canyon. Cameras captured numerous identifiable images of animals representing both mammals and bird species.
The purposes of this BE are: 1) to describe the physical and biological features of the Analysis Area, 2) to describe and map the plant communities, and 3) to identify the potential for special status species to occur within the Analysis Area.
Gila chub Gila intermedia was federally listed as endangered with critical habitat in 2005 (Federal Register 2005). Upper Mineral Creek, the watershed immediately upstream of the ASARCO Ray Mine Big Box Dam, was designated as critical habitat for Gila chub at the time of listing. According to Robinson (2008a), Gila chub were last documented in upper Mineral Creek in 2000. Subsequent surveys completed in 2002, 2006 and 2008 were not able to document the presence of Gila chub, and the species is considered extirpated from upper Mineral Creek (Robinson 2008a).
This letter report presents the results of the 2010 geotechnical testing program on scavenger and cleaner tailings. The results are also compared with the previous test programs in 2007 and 2009.
Research was carried out to improve acid rock drainage (ARD) prediction methodologies, focussing on resolving uncertainties in acid base accounting (ABA) methods.
