Benjamin Mapani

Benjamin Mapani completed his Honours Bachelor’s degree at the University of Zambia in 1986 proceeded to work as a Regional Mapping Geologist at the Geological Survey of Zambia. He produced two Map sheets. He briefly worked for a Zn and Pb mine and then proceeded for his M.Sc. in 1989-1990. In 1991 he secured a competitive Commonwealth Scholarship for his Ph.D., in Australia. He commenced his Ph.D., in 1991 and completed in 1993. He graduated in April of 1994. Thereafter he taught at the University of Zambia until 1997. Then joined the University of Zimbabwe in 1998 where he was tasked to build an International Masters Programme in Exploration Geology. This was a very successful programme that produced cadres that are working across the globe. In 2002, he moved to Namibia to begin and mount a geology programme at the University of Namibia. The Department began with two personnel for a period of 6 years, and now it is a full-fledged entity producing Masters and Ph.D. cadres. He served at UNAM from 2002 to 2019. In 2020 he joined NUST in the Department of Mining and Process Engineering as a Professor in Mining and sustainable development.
