S621o5.S8Rl* 651.6 »097H C78-016060-6 ACKNOWLEDGEMENTS The authors wish to acknowledge the financial assistance received from the British Columbia Ministry of Mines and Petroleum Resources. The discussions and advice of the Technical and Research Committee are much appreciated. We wish to express our thanks to the personnel at the various mines visited for their cooperation and assistance during our field studies. Without the aid and cooperation of B. Herman, J. Armanini, I. Reichenback, T. Walters, and the graduate students in the pedology laboratory at U.B.C., this study would not have been possible. Their dedication, constructive comments and general assistance can not be over evaluated. We thank S. Ames for her help in the field studies. We sincerely thank Mr. R.T. Gardiner, Cominco Ltd. (Trail) and Mr. A. Milligan, Kaiser Resources (Sparwood) for their interest, assistance in site locations and the pleasant discussions. We value the help obtained from Mr. G.A. Singleton, who designed the Soxhlet apparatus employed in the laboratory studies and for his helpful suggestions in regards to weathering. B.A. Como L.M.
