About Us


The Nigerian Geological Survey Agency is a parastatal under the Ministry of Mines and Steel Development. The Agency has the statutory role of providing relevant and up-to-date geosciences information necessary for economic development of Nigeria. This is accomplished through a systematic process of gathering, collating, assessment and dissemination of all information related to rocks, minerals and groundwater resources of the country.

The Agency was established by Act of the National Assembly via a bill of May 22, 2006. Its earliest precursor the Geological Survey of Nigeria (GSN), was set up in 1919 following the disbandment of the Mineral Survey of Northern and Southern Nigeria in 1909 and 1913, respectively.   


Geological Survey of Nigeria evolved as far back as 1903 and 1904 when the Mineral Surveys of the Southern and Northern Protectorates of Nigeria were established respectively by the British Secretary of State for the Colonies. The Mineral Surveys were to carry out broad reconnaissance survey of mineral resources of the Protectorates for use as raw materials for industries in Britain. In the course of their activities, mineral deposits such as Tinstone, Columbite, Bitumen, Lead-zinc, Ores, Coal, Pottery Clays, Iron Ore, Gold, and Marble etc were discovered in various parts of the country. The Geological Survey of Nigeria (GSN) came into existence in 1919 as an autonomous body. By 1930, the first permanent headquarters of GSN was set up in Kaduna with a satellite office in Jos in order to speed up its activities in the tin fields. While Kaduna remained the field headquarters, the administrative headquarters was moved to Lagos-the nation’s capital then.

The Minerals Ordinance of 1946 and the Cola Ordinance No. 29 of 1950 provided the legal basis for the development of Solid Mineral in Nigeria.

Immediately after independence, the autonomy of Geological Survey of Nigeria was withdrawn and it became administered since then as a Department under the supervision of various Ministries. The Department first came under the Ministry of Mines, Power and Lagos Affairs and later at various times under

  1. Ministry of Mines and Power- up to 1984
  2. Ministry of Mines, Power and Steel 1984 -1989; and 
  3. Ministry of Petroleum and Mineral Resources, 1989 -1995

“To evolve an open, transparent and flexible organization that would provide geosciences information and knowledge for wealth creation and national development”



“To emerge as the ultimate referral point for geosciences information and knowledge using highly qualified and skilled professional, cutting –edge technology and in collaboration with stakeholder”


The Nigerian Geological Survey Agency (NGSA) is a dynamic body in the area of geosciences and is always engaged in applied researches, Geoscientific information monitoring, Environmental sciences, and Mineral resources development in Nigeria. Being a parastatal under the Ministry of Mines and Steel Development (MMSD), it is charged with the responsibility of carrying out basic geoscientific research to advance the knowledge of geology and mineral deposits in Nigeria.



The Nigerian Geological Survey Agency (NGSA) primarily carries out the following activities:

  1. Geological mapping
  2. Geophysical surveys
  3. Geotechnical mapping
  4. Geochemical mapping
  5. Marine and coastal geological surveys
  6. Geohazard monitoring
  7. Mineral exploration
  8. Remote sensing interpretation
  9. Map production
  10. Laboratory services
