History of the Geological Survey of Tanzania (GST)

The Geological Survey was established in 1925 by the British Overseas Management Authority (BOMA) administration under the name of Geological Survey Department (GSD) as an independent governmental department. The primary objective was to speed up development of mineral resources of the Tanganyika Territory. In April 1926, the headquarters of GSD was set up in Dodoma by the first director, Dr. E.O.Teale. The main assignment of the GSD was to provide geological information acquired through geological mapping and reconnaissance mineral exploration in the country as well as prospecting for groundwater resources. The Minerals Laboratory was established in 1929 to support the geological mapping and mineral exploration.

Since its establishment, the Survey has undergone various re-organisational administrative changes under different Ministries including Ministry of Mines and Commerce (1935 to 1949), Ministry of Commerce and Industry (1960 to 1961), Ministry of Industries, Mineral Resources and Power (1964 to 1966),  Ministry of Water, Power and Mineral Resources (1978 to1981), Ministry of Minerals (1981 to 1984), Ministry of Energy and Minerals (1986 to 1990), Ministry of Water, Energy and Minerals (1991 to 1996) and Ministry of Energy and Minerals since 1996 to present.

In 2005 the Geological Survey was transformed into a Government executive agency established under the Executive Agencies Act No 30 of 1997 and was officially launched as a Government Agency on 23 June 2006 under the name Geological Survey of Tanzania (GST).

The Geological Survey has made notable achievements since its establishment about eighty years ago. The achievements include:

  • 85 % of the entire country has been geologically mapped and published geological maps as quarter degree sheets (QDS) are available at various scales. This has generated basic geological and mineralogical data and information used by investors in the mining sector.
  • Discovery of a substantial number of mineral occurrences some of which developed into world-class mines (eg. Kahama and Geita Gold Mines).
  • Increased contribution of the Mineral Sector to the country’s GDP from about 0.3 % in the 1980s to about 10 % at the turn of the century. The growth was facilitated by various economic policy changes by the Government during the late 1980s and the 1990s.
