Solid mineral potential in the southern Benue Trough: A review

Abstract

The Nigerian Southern Benue Trough has a wide variety of metallic, non-metallic, and energy minerals, making it a promising major mineral resource corridor.  The solid mineral potential of the area is evaluated by this review, which synthesizes the geological, geochemical, and economic data currently available. It emphasizes the impact of intricate stratigraphy, hydrothermal processes, and Cretaceous rift tectonics on mineralization patterns.  High-grade barite in Azara and Ishiagu, limestone in Gboko and Mfamosing, lead-zinc deposits in Abakaliki, and coal in the Lafia-Obi axis are important resources. Limited geological data, inadequate infrastructure, environmental degradation, and lax regulatory frameworks continue to impede development despite their strategic importance.  Artisanal businesses currently dominate mining activities, although industrial-scale investments are starting to appear.  Modernizing exploration, luring investment, and advancing sustainable mining methods are the goals of government programs like the MinDiver Project and growing private sector involvement.  In order to fully realize the economic potential of the Southern Benue Trough and make a significant contribution to Nigeria's objectives for energy transition and economic diversification, this analysis emphasizes the urgent need for integrated geological mapping, infrastructural development, and regulatory reform.
