Baseline Reports

This Phase I Environmental Site Assessment (ESA) is for approximately 147 acres referred to as Turkey Creek, also known as the JX Bar Ranch and J Slash X Ranch.

Phase I Environmental Site Assessment (ESA) for approximately 956 acres referred to as the Appleton Ranch Property. This property is comprised of a set of three private land tracts consisting of eight county assessor parcels within the larger (8,000 acre) Appleton-Whittell Research Ranch.

The Property is a private in-holding within the Tonto National Forest, located along Cave Creek about 6 miles north of the town of Cave Creek. The nearest large metropolitan community is Phoenix, Arizona, located approximately 25 miles south of the Property.

Phase I Environmental Site Assessment (ESA) for approximately 640 acres referred to as East Clear Creek. The property comprises the entirety of Section 9 in Township 14 North, Range 12 East relative to the Gila and Salt River Baseline and Meridian, in Coconino County, Arizona.

This report is an addendum to several previous reports that include detailed analysis and discussion of hydrochemical sampling results for surface water and groundwater in the Upper Queen Creek/Devils Canyon (QCDC) study area.

The purpose of this traffic study is to evaluate the current and future transportation system at the proposed Resolution Copper Mine expansion without and with the project. Traffic operations were analyzed at existing, key intersections located near the proposed mining operations and facilities during construction and final operations.

Hydrologic test wells HRES-01, HRES-02, HRES-03, HRES-04, and HRES-05 were drilled and constructed during the period February 2 to March 11, 2004. The test wells were drilled evaluate lithologic and hydrogeologic conditions within the Apache Leap Tuff, and were terminated in the uppermost part of the Whitetail Conglomerate. Final test well construction was designed to permit hydrologic testing of the Apache Leap Tuff aquifer, and to provide access for long-term monitoring of groundwater level and groundwater quality for the aquifer.

The primary objective of the testing presented in this report was to further enhance and expand the Project’s understanding of the potential geochemical reactivity of the scavenger tailings, although some process waters and pyrite tailings from the 2014 pilot plant were also tested.

This report summarizes the meteorological, upper air, nitrogen dioxide (NO2), sulfur dioxide (SO2), ozone (O3), and particulate matter (PM) data collected at the Resolution Copper Project near Superior, Arizona for the first quarter, January 1 – March 31, 2016.

Meteorological and air quality monitoring program to support several efforts during the mine development phases: environmental assessments, impact analyses, and documents required by NEPA; meteorological and air quality data to be processed and used as input for AERMOD dispersion modeling; and air quality baseline data and AERMOD analyses in support of an application to the Pinal County Air Quality Control District for air permits.
