Appendix H

This report provides chemical, physical, mineralogical, and microbiological procedures for the analysis of coal overburdens and the resultant minesoils. These step-by-step methods identify and measure rock and soil properties that influence advance planning, mining efficiency, post-mining land and water quality and long range land use.

The microbiological oxidation of iron and sulfur constitutes two key processes in mineral biotechnology. Both mesophilic and thermophilic bacteria have been described which can utilize inorganic compounds of Fe and S as electron donors (3, 5, 6). At present, although thermophiles are characterized by superior oxidation rates, only mesophilic iron- and sulfur-oxidizing acidophiles are used in large-scale leaching processes for metal recovery from sulfide ores.

Acid rock drainage (ARD) is produced by the exposure of sulphide minerals such as pyrite to atmospheric oxygen and water. The ability to identify in advance any mine materials that could potentially produce ARD is essential for timely implementation of mine waste management strategies for ARD control.

A series of flotation tests had been conducted at DML on the three individual composites that comprise MC-1. The initial scope of that test work was to evaluate if:

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

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 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 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.

The chemical composition of natural water is derived from many different sources of solutes, including gases and aerosols from the atmosphere, weathering and erosion of rocks and soil, solution or precipitation reactions occurring below the land surface, and cultural effects resulting from human activities.

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.
