Bauchi State has several mineral deposits. They include: Gold, Cassiterite (tin ore), Columbite, Gypsum, Wolfram, Coal, Limestone, Lignite and Iron ore. However, only a few of these are as yet being mined, as some of them occur only in traces. Thus, for example, cassiterite is mined in places like Gamau and Maijuju. Quarrying of granite and other rocks for road and other construction goes on in the south-western parts of the state within the basement complex and plateau area, especially in Toro LGA.
It is known that formal mining of tin within the Jos Plateau started in 1905 in Tilden Fulani, Toro LGA in Bauchi State. A monumental mining beacon has been erected at this first tin mining site. The various minerals in the state are in some cases viable basis for investments. An example is the Misau Ceramic Factory, based on locally available clay and silica sand.
