Curriculum Vitae Y.T. John Kwong, B.Sc., M.Sc. (McMaster), Ph.D. (UBC), P.Geo. (SK) Senior Environmental Scientist/Research Scientist, CanmetMINING, Ottawa Tel: (613) 943-0525; Fax: (613) 996-9041; E-mail: John.Kwong@NRCan-RNCan.gc.ca _________________________________________________________________________________________ Thirteen years as Senior Environmental Scientist/Research Scientist, CanmetMINING, Ottawa. Develop, conduct and manage research projects pertaining to contaminant transport and attenuation, mine waste characterization and management; provide expert advice to internal and external clients on related issues. - - - Completed studies on water covers at the Louvicourt Mine (Quebec), chemical stability of impounded tailings at Mount Nansen (YT), submarine tailings disposal and deep-sea tailings placement, transformation and mobilization of arsenic and antimony, chemical stability of paste backfill, and biofilm formation on submerged tailings. Served as a federal EA reviewer on ARD/ML issues for many proposed mining and development projects (e.g. Prosperity Au-Cu, Enbridge Northern Gateway pipeline, Mary River iron, Kiggavik uranium); participated in expert working groups advising on the decommissioning of abandoned mines in the Keno Hill area (YT), the Giant Mine (NWT) and Sydney coal mines (NS). Current research endeavours address mine waste management in a changing climate, performance of Canadian mines in water quality protection, radium remobilization from submerged uranium tailings, metal background and mobility at Keno Hill as well as environmental ore deposit models for the Canadian North. Two years as Senior Environmental Scientist, Klohn-Crippen Consultants, Calgary. Conduct and manage projects with a significant AMD and geochemistry component; provide technical review for related projects across Canada and overseas. - Designed investigation programs and produced nine reports on pre- and post-mine AMD and metal leaching assessments for various projects in Canada (BC and NWT) and South America (Peru). Nine years as Research Scientist, National Hydrology Research Institute, Saskatoon. Conduct research on the geochemistry of geologic materials in contact with contaminated surface and ground waters and related issues. Some significant projects completed include: - Prediction and prevention of acid rock drainage from a geological and mineralogical perspective (MEND Project 1.32.1) Galvanic interaction in sulphide oxidation and its impact on mine water chemistry Post-mine aqueous metal transport in the Keno Hill mining district, Yukon Climatic warming and permafrost degradation along the McKenzie Highway Transport and attenuation of heavy metals in the northern environment Acid generation and metal leaching at the abandoned Mt. Washington Mine, BC Version : 28-July-2009 Page 1 Ten years as Laboratory Scientist (Mineralogist), B.C. Ministry of Energy, Mines and Petroleum Resources, Victoria. Conduct X-ray diffraction analysis in support of geological mapping and exploration programs; collaborate with staff geologists on a variety of resources assessment projects. - - Completed doctoral dissertation on supergene alteration of the Afton porphyry Cu-Au deposit and a professional paper (bulletin) on the evolution of the Iron Mask batholith and its associated copper mineralization Published papers on supergene alteration at Afton mine, petrogenesis of a gold skarn and a carbonatite enriched in rare earth elements, use of coal ash mineralogy as an indicator of oxidation, porphyry tailings as a source of titanium, and, zeolites as an industrial mineral resource in British Columbia Selected Recent Publications (pertaining to ARD/ML and contaminant transport): Beauchemin, S., Kwong, Y.T.J., Desbarats, A.J., MacKinnon, Percival, J.B., Parsons, M.B. and Pnada, K.
