About Dr Samuel Nunoo

Dr. Samuel Nunoo is a postdoctoral fellow at the Department of Geology, Faculty of Science, University of Johannesburg, APK Campus. He is a Senior Lecturer at the University of Ghana (UG), Department of Earth Science (DoEs), and a PhD holder from the University of Johannesburg, South Africa, where he worked on unravelling the potential sources of gold mineralization in NW Ghana. His research over the years focused on understanding the metallogenic source(s) of gold and associated metals in Paleoproterozoic terrains. He is zealous in combining field-relations, U-Pb zircon geochronology and isotopes of Lu-Hf, carbon and sulphur in answering crustal evolution challenges and mechanisms leading to metal sequestration and deposition. Samuel is also a module leader (the metallogenic aspect) of the Basin Research Group, part of the West African Exploration Initiative (WAXI-IV). He is also a co-investigator of an AGATE-sponsored project that investigates structural control of gold mineralization in SW Ghana. He has recently assumed an office as the Chairperson of the Southeastern Sector of the Ghana Institute of Geoscientists. As one who supports the need for a clean energy and climate, Samuel is part of a French-funded Nkambo project piloting to understand the geological characteristics of the Kambale Graphite in NW Ghana, an addition to the global critical mineral inventory.
