IGS in Suriname – A roadmap for a new Geological Survey


IGS and GAF AG (Germany) are together working on a 12-month long project commissioned by the Suriname Ministry of Natural Resources entitled: ‘International mining specialist to support the establishment & the commissioning of the Minerals Institute of Suriname: Cadastre & Geological Survey’. This is one of several initiatives of a loan agreement between Suriname and the World Bank called the ‘Suriname Competitiveness and Sector Diversification Project’.

Suriname has an interesting geology with much of it located on the Guiana Shield, which has a high potential for a range of minerals including gold, diamonds, other metallic minerals as well as kaolin, critical minerals (including rare earth elements) and dimension stone. The extractive sector of Suriname is dominated by oil, gold and bauxite. The government wants to promote a regulated and responsible expansion of its mining industry by creating a new mining authority known as ‘Delfstoffen Authoriteit Suriname’, whose objective will be the promotion, coordination, regulation, monitoring and inspection of its mineral sector in a sustainable manner. Our project supports these objectives by developing a modernised mining cadastre and a new Geological Survey.

IGS is responsible for the development and early-stage implementation of a road map for a new Geological Survey. An important component of the work will be to identify the key geoscience and geodata programs that will attract investor interest in the country. GAF AG is responsible for the assessment and development of a road map for the implementation of a revised and modernised cadastre system. Both IGS and GAF AG have visited the country as part of the inception phase and are now working on the assessment part of the project for these components. Further updates for this project will be posted as the project progresses.

Kick-off meeting for the Geological Mapping Program of the Arabian Shield


IGS as leader of the Technical Partner Consortium to the Saudi Geological Survey participated in the Kick-off meeting (KOM) for project Geological Mapping of the Arabian Shield, which is part of the Regional Geoscience Program (RGP), executed under the leadership of the Saudi Geological Survey. The meeting, which was organized by the contractor China Geological Survey (CGS) and its logistics partner China National Geological & Mining Corporation (CGM), took place from 19-21 March 2023 at Aliaa Swissotel Living Hotel in Jeddah with some 50 delegates from seven nations.

With 15 presentations, the contractor explained how the 11-year project should be implemented. The objective is to improve the geological knowledge of the Arabian Shield, which covers some 650,000 square kilometers, by generating a new set of geological maps. 257 maps at a scale of 1:100,000 are required. The maps will be based on new geological field surveys (undertaken at a scale of 1:50,000) including analytical work, the results of currently operational airborne geophysical and ground-based geochemical (stream sediment) surveys, an updated lithostratigraphic framework, and legacy data.

IGS is responsible for the supervision of all works and quality control of all products of project Geological Mapping of the Arabian Shield.

Airborne Geophysical Survey and Geological/Geochemical Mapping of Karamoja, Uganda


After an interruption of a year due to security concerns, field work for the geological mapping and the geochemical survey, resumed in February 2023, in the Karamoja region. IGS is the official partner of the Directorate of Geological Survey and Mines (DGSM) in collaboration with PGW and is responsible for controlling the quality of all project related activities. The mapping and the geochemical sampling are conducted by field teams contracted by Xcalibur Multiphysics and the DGSM. In close cooperation with IGS experts and its partner, target areas were determined using the latest geophysical data and legacy field data. The results of the geology and geochemistry for the Karamoja region will be of great assistance in the future exploration of mineral resources.

Due to security-related issues, IGS conducts much of its quality control and review of project deliverables, remotely.

A joint exercise in Mbale (Eastern Uganda) between the client (DGSM), the contractor (Xcalibur Multiphysics) and the quality controller (IGS/PGW) where stream-sediment and bulk-rock samples were inspected and transported to the preparation laboratory in Entebbe. The truck contains samples from the first of nine zones that were successfully sampled, with more to follow. After processing in Entebbe, the samples are sent to a commercial laboratory for multi-element analysis.
