Mining industry of Nigeria - Wikipedia

Mining is the extraction[removal]of minerals and metals from the earth. The Nigerian Coal Corporation (NCC) is a parastatal corporation that was formed in 1950 and held a monopoly on the mining, processing, and sales of coal, lignite, and coke products until 1999. Coal was first discovered in Enuguin 1909 at the Udi Ridge in Enugu,This was found by a British mine Engineer known as Albert Kitson.
