Jacob Waples is a Principal Consultant with Life Cycle Geo. He has over 20 years of experience in mining geochemistry evaluations, including geochemical modeling, closure evaluations and material characterizations. He is experienced working as a part of multidisciplinary teams to support closure planning, permitting, and mine planning studies (e.g., prefeasibility and feasibility) as for geochemical considerations. He has experience modelling contaminant transport, pit lake chemistry, and seepage chemistry from waste rock dumps and heap leach facilities. In the last ten years, his modeling focus has been on tailings geochemistry for closure evaluations, including evaluations of kinetic pyrite oxidation, oxygen ingress dynamics, and cover performance. Jake has experience with copper, gold, silver, and lithium projects throughout the world, including Chile, Peru, Australia, Ghana, Indonesia, Argentina, and Mexico. In the United States, he has worked on modeling, permitting, and characterization projects in Arizona, New Mexico, Nevada, Utah, California, Minnesota, South Dakota, and Colorado. Jake is a professional geologist in the state of Wyoming, with a Master’s in geology from the University of Colorado and a Bachelor’s degree in Earth & Environmental Science from Wesleyan University.
