New Developments


The Government of Tanzania, through the Ministry of Energy and Minerals (MEM), has received a credit from the International Development Association (IDA) for implementation of the Sustainable Management of Mineral Resources Project (SMMRP). The development objective of the proposed Project is to improve the socio-economic impacts of mining for Tanzania and Tanzanians, and Government capacity to manage the mineral sector and enhance local and foreign investments.

For easy coordination, The Sustainable Management of Mineral Resources Project (SMMRP) has four components, namely:
A. Improving the Benefits of the Mineral Sector for Tanzania by addressing small-scale and artisanal mining, linkage of the mineral sector with local economies and development of human resource for the mineral sector;
B. Strengthening governance and transparency in mining by supporting policy and legal review, and focused public awareness campaigns; strengthen institutional capacity of the Ministry of Energy and Minerals (MEM) to manage the mineral sector and its linkage with other government institutions;
C. Stimulating Mineral Sector Investment through upgrading of geologic information; strengthening the Information and Promotion Unit at the Ministry of Energy and Minerals and to improve public awareness and promotion of the mineral sector; and
D. Project Coordination and Management which entails supporting operations of the Project Management Team (PMT), Geological Survey of Tanzania (GST) GST, Project Steering Committee (PSC) and the Project Technical Committee (PTC).


The Geological Survey of Tanzania has been assigned to implement portions of component C above.
Airborne Geophysical Survey
Together with a consultant, GST personnel shall monitor the contractor during the airborne geophysical survey. GST will also ensure the contractor gets all necessary help throughout the project. GST personnel will participate in the data processing.

Geological and Geochemical Mapping
The following activities shall be executed during the project:

  • Assessment and interpretation of the existing geological, geochemical, remote sensed and geophysical information of the areas to be surveyed;
  • Carrying out detailed geological, geochemical as well as conducting ground geophysical survey follow-ups over selected areas with favorable geological conditions for the existence of mineral resources;
  • Processing and interpreting the field geo-data acquired;
  • Integrating the geological and geochemical data to the information/data obtained from the airborne geophysical survey and ground geophysical follow-up to generate project products and publish the findings; Develop geoscientific inventory and mineral resources assessment to attract potential investors in mineral exploration and mine development.

Geological Mapping

Eighteen (18) geological Quarter Degree Sheets covering an approximate area of 54,000 km2 have been selected for geological mapping and maps will be published at a scale of 1:100,000. Out of these, there are 12 unmapped QDS and six (6) QDS will be up-dated from a scale of 1:125,000 to 1:100,000. In addition two blocks covering a total of 314,928 sq km will be compiled followed by field checks and maps published at scale of 1:500,000
Upgrading of Six geological QDSs (scale 1:100,000)
Acquisition of new data and information through field geological mapping, geophysical and geochemical surveys as well as updating existing geological maps. Six (6) QDSs covering an area of about 18,000 km2 have been selected for updating. They include QDSs 146, 147, 148 and 165 (Handeni and Kilindi) in Tanga region; QDS 228 and 229 (Lupa Goldfield in Mbeya region) (see figure 2). The scope of work to be undertaken include compilation of available data and information; field checks and map editing, data processing and interpretation; map preparation, publication and reporting.
Geological mapping of 12 QDSs (scale 1:100,000)
A total of 12 QDSs covering about 36,000 km2, will be mapped and compiled at a scale of 1:100,000. These include QDS 82, 83, 101, 102 (Singida-Iramba Sekenke); QDS 185 (Coastal region); QDS 178, 79 (Dodoma-Mafurungu); QDS 272, 273, 230 (Mbeya region); and QDS 263 (Ruvuma region). The work shall involve compilation of available data and information; field work; petrological and petrophysical studies; laboratory analysis and map preparation at a scale of 1:100,000.
Compilation of regional geological, geophysical and mineral potential block maps (scale 1:500,000)
This will entail compilation and synthesis of existing data and information; conducting geological and geophysical field checks in selected areas; laboratory analysis; data compilation and production of geophysical maps from the old airborne geophysical data archived at GST. Samples for geochronology age determination of rocks will be collected for the purpose of age correlation. Two blocks covering 324 km2 have been selected for compilation of regional geological, geophysical and mineral potential maps at the scale of 1:500,000. They include the Singida-Handeni corridor (Block A with 54 QDS sheets) and Mbeya-Songea corridor (Block B with 54 QDS sheets) as shown in figure 2. Twenty eight (28) QDSs are within the areas selected for the airborne geophysical survey in the Singida – Handeni corridor.
