History of the Geological
Survey of Tanzania (GST)
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.
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

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).
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.
