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, 2014.
An ecological overview for approximately 59.9 hectares of land along Tangle Creek within the Tonto National Forest in Yavapai County, Arizona (referred to as LX Bar Ranch). This ecological evaluation was conducted to identify the type and relative condition of the biological resources found on and to evaluate ecological characteristics of the property to identify remarkable resource attributes, and to briefly assess their conservation values in reference to local and regional contexts.
Raptor survey was conducted on a parcel of land administered by ASLD near Florence Junction, Pinal County Arizona. The purpose of this study was to gather information on raptor use of the Far West site and to provide baseline survey information in order to analyze potential impacts of the proposed mine features in the future.
