Though mining in Nigeria started in 1905, the industry only accounts for 0.3% of the nation's GDP. The domestic mining industry is underdeveloped, leading to the importation of some industrial minerals that the country has in abundance. One such mineral with great industry use and but largely underdeveloped in Nigeria, is gypsum.
