Appendix H

SGS was contracted by Resolution Copper Mining LLC (Resolution) to complete environmental and geotechnical characterization of tailings generated during pilot plant (PP) testing of Cu/Mo ore from the Resolution Copper property located at Superior, Arizona (SGS Project reference No. 12074-001). The purpose of the environmental test program was to assess the geochemical, acid rock drainage (ARD), contaminant release and geotechnical properties associated with the tailings materials.

This data summary report summarizes laboratory testing procedures and test results that were completed on concentrate produced during mineral processing, feedstock material, and metallurgical testing (rougher, cleaner, and whole) tailings produced from the lock cycle float tests.

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.

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.

This technical memorandum presents the results from the 43-week extended kinetic geochemical characterization program of scavenger tailings for the Resolution Copper Project conducted by Golder Associates (Golder). The program was carried out to evaluate the environmental stability of the tailings and supplement the static testing program reported in Golder 2007.

This technical memorandum presents the results from the 20-week kinetic geochemical characterization program of cleaner and scavenger tailings for the Resolution Copper Project conducted by Golder Associates (Golder). The program was carried out to evaluate the environmental stability of the tailings and supplement the static testing program reported on in a previous document (Golder 2007).

This technical memorandum presents the results from the static geochemical characterization program of cleaner and scavenger tailings for the Resolution Copper Project .

This letter report describes the static geochemical testing carried out on cleaner and scavenger tailing slurries. The static testing program is designed to provide data on the short term geochemical behavior of the tailings solid phase as well as an indication of the quality of associated process waters.

Research was carried out to improve acid rock drainage (ARD) prediction methodologies, focussing on resolving uncertainties in acid base accounting (ABA) methods.

This guidance manual describes the process that an Aquifer Protection Permit (APP) applicant should follow in selecting the Best Available Demonstrated Control Technology (BADCT) for a specific mining facility and site in accordance with Arizona Revised Statute (A.R.S) 49-243.B.1.
