Mining activities began in 1902 and the earliest recorded mineral mined was tin ore (MMSD, 2017). In 2015, Nigeria's solid minerals and mining sector accounted for a paltry 0.3% of the GDP which increased slightly to about 0.5% in 2018. The sector has contributed only 0.02% of Nigeria's total exports.

Mineral exploration is the process of searching for evidence of any mineralisation hosted in the surrounding rocks. The general principle works by extracting pieces of geological information from several places, and extrapolating this over the larger area to develop a geological picture. Exploration works in stages of increasing sophistication ...

Minerals from Hot Underground Water. Magma heats nearby underground water, which reacts with the rocks around it to pick up dissolved particles. As the water flows through open spaces in the rock and cools, it deposits solid minerals. The mineral deposits that form when a mineral fills cracks in rocks are calledveins (Figure below).
