Three representatives from Montgomery & Associates (M&A) recently gave a virtual presentation on mining hydrogeology to the University of Arizona Society of Mining, Metallurgy, & Exploration (SME) student chapter. Brandon Schneider, a groundwater modeler in M&A’s Santiago, Chile, office spoke about his background and his role in some recent lithium brine projects in South America. Megan Zivic, P.G., of M&A’s Tucson office shared how field investigations are conducted and how the data are used to help mining companies understand and better manage groundwater at their sites. Courtney Pratt, a hydrogeologist in M&A’s Salt Lake City office presented on her experiences conducting underground aquifer testing at a gold mine in Nevada and installing instrumentation at a large open-pit copper mine in Utah. The students asked insightful questions and participated in an engaging discussion. M&A staff would like to thank the U of A SME student chapter for the opportunity to share our expertise.
