In a significant move towards enhancing Nigeria’s raw material utilization, the Raw Materials Research and Development Council (RMRDC) conducted a field visit to the Nsu clay deposits located in Agbaghara Nsu, Ehime Mbano Local Government Area of Imo State recently. This initiative is part of RMRDC’s broader agenda to map out solid mineral resources across Nigeria, with an aim to bolster the country’s economic framework through sustainable resource development.
Led by Imo State Coordinator Mr. Enemuo David, the team aimed to evaluate the existing mining operations, identify challenges, and explore the potential industrial value of Nsu’s clay deposits, particularly kaolin. Interacting with local miners and community members revealed insights into traditional mining practices, which have been in place for generations.
The clay deposit spans approximately 10 hectares and is primarily mined by local residents, including landowner Mrs. Catherine Chigozie Opara, who has overseen activities since they began in 2022. The mineral is extracted using artisanal methods, which have raised concerns regarding safety and efficiency. Observations indicated that significant overburden must be removed—over 40 feet in some areas—before reaching the kaolin layer characterized by its varied colors, including purple, gold, red, brown, and white.
The RMRDC team identified several challenges during the visit, including unregulated mining activities, the absence of standardized measurement systems for clay output, and outdated extraction methods. Mr. Enemuo noted that these gaps require urgent attention. He recommended the formal registration of operators to ensure regulatory compliance, the adoption of standardized measurement systems for clay sales, and the modernization of mining practices to enhance productivity while ensuring safety. He further stated that laboratory analysis would be undertaken to determine the mineralogical composition and industrial suitability of the clay.

Despite these challenges, the field team concluded that the Nsu clay deposits hold significant potential for industrial applications, particularly in ceramics, brick manufacturing, and as filler materials across various industries.
The state Coordinator noted that Nsu clay deposit presents a promising opportunity for local economic development within Imo State and urged for the implementation of an improved practices and fostering of institutional support, according to him, this valuable resource can contribute significantly to Nigeria’s raw material supply for various industries.
He observed that the findings from the visit underscore the need for further research and development to unlock the full potential of Nigeria’s geological treasures.
