This document summarizes a geology internship from summer 2016 to December 2019. It discusses the intern's educational background and experiences with drilling, ore control, hydrogeology, production analysis, mine design, block modeling, and using hydrologic surfaces for mine planning. The intern thanks Barrick Gold, the Cortez Hills Underground mine, and Graeme Stroker and the CHUG Drilling Group for the opportunity.
