Principal Hydrogeochemist Patrick Williamson recently presented a one-day short course on “International Best Practices for Environmental Management of Mines” at the Forum Internacional de Capacitación y Educación Minera (FICEMIN) in Zacatecas, Mexico. The course provided students with an overview of best management practices for mine environmental management, with a focus on the two topics that present the greatest long-term risk to a mine, waste management and water quality/supply. This was the third year that Patrick has participated in the 3-day FICEMIN training event, which provides a selection of one-day training courses in Spanish to Mexican mining professionals, covering a range of topics in mining engineering, environmental management, metallurgy, geology, health & safety and maintenance. The previous two years, Patrick lectured on geochemical characterization and management of mine waste. Mr. Williamson received his Bachelor’s Degree in Geology from the Colorado College and a Master’s Degree in Aqueous Geochemistry from the University of Colorado at Boulder. He is a Professional Geologist (CA) and a Qualified Person (MMSA). His 30- year career has focused on environmental geochemistry and hydrogeology, starting in the late 1980s on Superfund remedial investigations and feasibility studies, and evolving over time to focus on regional water resources, mine waste rock characterization and management, social license for mine impacts on water quality and availability, and mine waste management. He speaks fluent Spanish, having lived in Colombia, Venezuela, Peru and Mexico, and managed international mining consulting practices in Mexico.
