About
The Nigeria Mining Chamber (NIMACH) is a private sector advocacy and representative body for the mining industry in Nigeria, which the government is actively seeking to develop as part of its diversification away from oil and gas dependency. Nigeria has significant mineral resources including iron ore (Agbaja, Kogi State), gold (Segilola — Nigeria's only operating large-scale gold mine, operated by Thor Explorations, producing approximately 91,910 oz in 2025), coal, limestone, barite, lead-zinc, bitumen, tin, columbite, and lithium. NIMACH works alongside the Ministry of Solid Minerals Development and the Nigerian Mining Cadastre Office (MCO) to develop the Nigerian Minerals and Mining Act 2007 framework. Nigeria's mining sector has historically been vastly underdeveloped relative to its oil and gas sector, contributing less than 1% of GDP despite substantial mineral endowments. The government's 'Solid Minerals Drive' under the Tinubu administration (2023-present) is targeting growth of the sector to 3% of GDP. NIMACH also engages on ASM formalisation, artisanal gold mining (particularly in the northwest), and the development of Nigeria's substantial gold belt in Osun and Kwara states.
