This technical memorandum was prepared to summarize results of drilling and construction at hydrologic test wells PHRES-01, PHRES-02, PHRES-03, and PHRES-04. The wells were installed to provide observation wells during the long-term pumping test at well HRES-09, and to provide locations for characterization of fracture distribution and hydraulic conductivity in the Apache Leap Tuff (ALT) aquifer in the vicinity of hydrologic test well HRES-09.

In 2015 Audubon Arizona organized and conducted standardized surveys on three reaches of Queen and Arnett Creeks near Superior, Arizona, in order to document yellow-billed cuckoo occurrence and abundance and to provide a basis for management recommendations.

This report is the 2012-2013 annual report on the field testing program for Resolution tailings. It also represents the conclusion of the project and the final evaluation of the leachate trends. The testing program, developed by Golder Associates Inc. (Golder) with Geochimica (Golder/Geochimica), included cleaner and scavenger tailings from the proposed Resolution Copper Project.

Pit lakes are an increasingly common legacy of modem, large-scale surface mining operations. Pit lakes formed in open pit metal mines, where base and precious metals are extracted from ore deposits hosted in predominantly igneous and metamorphic silicate rocks, comprise one category of pit lakes.

Starting with geological data, this paper estimates the seismicity for applications in seismic risk studies. The rate at which seismic moment is released can be estimated on a fault when the slip rate is known. Then, provided all of the deformation is released seismically, by assuming the relative frequency of different sizes of earthquakes, the absolute frequency of events can be obtained.

This paper is a progress report on the mapping effort for the central and eastern U.S.
