Overview
IntroductionNigeria continues to face a severe illegal mining problem that undermines national revenue, endangers communities, and fuels insecurity across mineral-producing regions. Reports indicate that more than 500 unauthorised mining sites operate nationwide, involving nearly two million people engaged in informal 1 extraction of gold and gemstones. Many of these sites are unregulated and, in several cases, controlled by coordinated criminal networks that smuggle minerals 2 outside the country. These activities contribute to land degradation, water contamination, community exploitation, and rising insecurity in rural mining 3 areas. The Nigerian Minerals and Mining Act (NMMA) 2007 provides the primary regulatory framework for exploration, mining, and quarrying activities.
It sets out licensing requirements, environmental obligations, and safety standards for mining operators. However, enforcement has struggled to keep pace with the scale of illegal mining. The Mines Inspectorate Department, the Nigeria Security and Civil Defence Corps (NSCDC), and the Nigeria Police Force share enforcement duties, but chronic underfunding, inadequate technical training, weak inter-agency coordination, and overstretched mandates have limited their 4 effectiveness. As a result, enforcement has often been reactive rather than preventive, especially in remote and high-risk mining corridors. The consequences of weak enforcement are evident in several documented incidents.
In Zamfara State, widespread lead poisoning linked to illegal artisanal gold mining killed at least 500 children between 2010 and 2012 and left thousands 5 needing urgent treatment. More recently, in June 2024, heavy rainfall caused a mining pit to collapse in Niger State, trapping dozens of miners and leading to 6 multiple fatalities. These tragedies illustrate persistent breaches of mining and environmental laws and highlight the need for a dedicated agency capable of sustained, specialised enforcement.
