Mapping Groundwater Contamination and Ecological Risks from Illegal Mining in Nigeria: A Geophysical and Microbial Perspective

Olomola Sunday Adesanmi is a Near-Surface and Exploration Geophysicist and an aspiring

researcher dedicated to using geoscientific tools to tackle technical, environmental, and

societal challenges in the exploration sector. He holds a Bachelor of Technology degree in

Applied Geophysics and has acquired practical experience in field data analysis and interpretation, focusing on mineral exploration and environmental applications.


He was part of Team Larimar, which was selected as a finalist in both the African and Global

rounds of the fifth Frank Arnott - Next Generation Explorers Award for their work in mineral systems and statistical analysis of copper deposit exploration. His team later emerged as one of the runners-up in the global competition. Most recently, he was named a finalist for the Oxford Africa Innovation Seed Fund, where he is presenting his team’s project, “Mapping Groundwater Contamination and Ecological Risks from Illegal Mining in Nigeria: A Geophysical and Microbial Perspective.” This initiative aims to address water quality issues through geospatial and microbial mapping and community-based approaches.


Beyond his academic and research pursuits, Sunday actively contributes to open-source

projects and engages in interdisciplinary collaboration and community-driven initiatives. He is committed to advancing research and developing scalable solutions that promote

sustainable development in near-surface and exploration geophysics.

Junior Duvald YONE NJOYA is a Master 1 graduate in Microbiology from the University of

Yaounde 1 in Cameroon, possessing comprehensive skills in microbiological analyses, from

sampling to results interpretation and adept laboratory manipulation.

While harboring an early interest in geology fostered during his secondary education, his passion for microbiology and microorganisms ultimately led him to pursue a Bachelor's degree in Microbiology at the University of Yaoundé 1, which he completed in 2022-2023.

Simultaneously nurturing his geological curiosity, he participated in the Next Generation

Explorers Award competition, where his team secured the Innovation Prize. This success

propelled him to the Next Generation Explorers Award Africa competition at the SAGA

conference in Namibia (October 2024) and a presentation at the PDAC conference in

Toronto, an event uniting young geologists and students from diverse fields. Driven by an unwavering passion for both microbiology and geology, he continuously seeks to expand his

knowledge in both domains. Most recently, this ambition has driven him to compete for the

Oxford Africa Innovation Seed Fund with a project that uniquely blends microbiology with

geophysics: “Mapping Groundwater Contamination and Ecological Risks from Illegal

Mining in Nigeria: A Geophysical and Microbial Perspective.” This project aims to

demonstrate the impact of mining exploration on surrounding populations, based on proven

microbiological risk factors through geospatial and microbial.


A young and highly motivated individual, Junior is distinguished by his ability to thrive in

collaborative settings, consistently embracing challenges in his pursuit of knowledge and

innovation. Upon completing his Master's degree, Junior aspires to work as an environmental engineer, contributing to the development of sustainable solutions for water resource management.
