The Nigeria Security and Civil Defence Corps (NSCDC) Mining Marshals have intensified nationwide enforcement against unlicensed mining, with recent operations leading to the arrest of 671 suspected illegal miners and securing several convictions in courts across the country. The crackdown underscores the federal government’s push to formalise the solid minerals sector, protect critical infrastructure, and deter economic sabotage linked to illicit mining activities.
Scale of the crackdown
The figure of 671 arrests reflects cumulative enforcement actions since the Mining Marshals unit was established in 2024, as NSCDC leadership has periodically updated authorities on the scope of illegal mining and associated prosecutions. In public briefings, the Corps has reported that hundreds of suspects have been detained, with a significant subset charged to court and a number already convicted, including both Nigerian and foreign nationals.
Alongside arrests, the Marshals have identified and shut down numerous illegal mining sites and mineral trading centres, recovered illicitly extracted minerals, and handed reclaimed sites back to licensed titleholders, aiming to restore revenue streams to the state and legitimate operators.
Operational approach and collaboration
The Mining Marshals operate as a specialised enforcement arm within NSCDC, deploying field inspections, intelligence-led raids, and joint operations with other security and regulatory agencies to target unlicensed mining and mineral trafficking. The unit’s mandate includes safeguarding mining infrastructure, enforcing compliance with the Nigerian Minerals and Mining Act, and supporting prosecution efforts through evidence collection and case documentation.
Operations have spanned multiple states with active solid mineral deposits, including Niger, Nasarawa, Kaduna, Plateau, Kogi, Kwara and others, with the Marshals frequently parading suspects, displaying seized minerals and equipment, and issuing public warnings to deter offenders. In some instances, the Corps has retrained and deployed additional personnel as mining marshals to expand coverage and strengthen monitoring at known hotspots.
Prosecutions and convictions
A core objective of the Mining Marshals’ work is to move cases from arrest to conviction, with NSCDC and the Ministry of Solid Minerals Development publicly stating that securing judgments is essential for deterrence and sector discipline. Officials have reported that a large number of those arrested have been charged in federal and state courts, with “several convictions” recorded against both local and foreign offenders.
High-profile rulings have included prison sentences and deportation orders for foreign nationals found guilty of illegal mining, as well as forfeiture of millions of naira in proceeds and equipment to the federal government. These outcomes are being highlighted by authorities as precedents to signal that unlicensed extraction and mineral trading will attract criminal sanctions, not just administrative penalties.
Government statements and policy context
The Minister of Solid Minerals Development, Dr. Dele Alake, has framed the Mining Marshals’ work as central to the government’s broader strategy to formalise mining, attract investment, and curb the financing of insecurity through illicit mineral trade. In anniversary briefings and operational updates, he has stressed that convictions are a priority, arguing that visible enforcement and punishments are necessary to change behaviour in the sector.
NSCDC Commandant General Ahmed Abubakar Audi has similarly linked the arrests and prosecutions to the Corps’ wider mandate to protect critical national infrastructure and combat economic sabotage, describing illegal mining as a threat to both the economy and public safety. The Corps has also used occasions such as International Civil Defence Day to present aggregate statistics on arrests across multiple offences, including illegal mining, as evidence of its operational impact.
Recoveries and site reclamation
Beyond arrests, the Mining Marshals have focused on reclaiming illegally occupied mining sites and returning them to legitimate titleholders, a process intended to restore lawful production and tax revenue. Reports indicate that dozens of sites have been recovered and handed back, while large quantities of minerals—ranging from fluorite and monazite to gold and other solid minerals—have been seized during raids.
In several operations, the Marshals have also confiscated mining equipment, vehicles and motorcycles used to facilitate illegal activities, and in some cases sealed suspected mineral buying and processing centres operating without requisite approvals. These measures are presented as part of a comprehensive enforcement model that targets the entire value chain of illicit mining, from extraction to trade.
Challenges and inter-agency dynamics
The enforcement drive has not been without friction. NSCDC has at times accused elements within other security agencies, including the police, of obstructing investigations and prosecutions of illegal miners, alleging interference with ongoing cases and attempts to undermine the Marshals’ operational control of crime scenes. Such disputes have been raised in petitions to legislative committees, with the Corps calling for probes into alleged sabotage of its anti–illegal mining work.
These tensions highlight the complexity of coordinating multi-agency responses to illegal mining, particularly where lucrative informal networks and foreign participation are involved. Nonetheless, federal authorities continue to emphasise collaboration among NSCDC, the Ministry of Solid Minerals, the EFCC, the military and other bodies as essential to sustaining the crackdown.
Implications for the mining sector
The wave of arrests and convictions is being positioned as a turning point in Nigeria’s efforts to bring its solid minerals sector under stricter regulatory control. By publicising the number of suspects detained, cases filed and judgments secured, the government aims to deter would‑be violators and encourage operators to seek proper licences and comply with environmental and safety standards.
For communities and local stakeholders, the message from NSCDC and the ministry is that engagement in unlicensed mining carries serious legal risks, and that reporting suspicious activities is a civic duty to protect national resources. At the same time, the reclamation of sites is intended to create space for formal, investment‑driven mining that can generate jobs and revenue under the law.
