IGS (International Geoscience Services) Ltd is a UK based, specialist consultancy supporting and promoting the mineral resource sector by collecting, quality control, defining technical specifications, compilation, value adding, interpreting  and serving of geodata.


1 – National Mapping Programmes

IGS implements large geological, geochemical and geophysical mapping programmes used by governments and industry to support and stimulate mineral exploration.  It supervises, monitors and signs-off on the quality of geological and geochemical mapping and airborne geophysical data.

2 – Institutional Strengthening

IGS provides a wealth of strategic management knowledge and experience to assist national geological survey organisations to transform and realign their strategic objectives and operations.

3 – Geodata Management

IGS are experts in the collection, interpretation, management, and serving of geodata typically held by geoscience survey organisations e.g., processing and interpreting geophysical data, setting up geoportals, compiling prospectivity maps and integrating geological map data on GIS platforms.

                                                                                                                              Geophysical Map

4 – Training and Capacity Building

IGS is experienced in delivering training and capacity building projects around the world in a variety of geoscientific disciplines.

5 – Target Generation

We help to identify prospective areas for mineralisation using innovative approaches by applying semantically driven technology and AI technologies for regions, countries or discrete geological terranes.

Project experience

IGS is internationally renowned for its supervision and quality control of large geodata acquisition programmes commissioned by governments, worldwide – funded by the World Bank, national governments and other agencies. IGS is the lead party as Technical Partner to the Saudi Geological Survey for the surveying of the Arabian Shield in Saudi Arabia (600 000 km2). This multi-year project provides quality control of contractors for the geological mapping, geochemical sampling programme, airborne geophysical survey, upgrading the National Geodatabase and the National Core Library of contractors.

Completion of field work on the High-Resolution Geochemical Survey of the Arabian Shield (GSAS) project


The field work of the High-Resolution Geochemical Survey of the Arabian Shield (GSAS) project which covers the entire Arabian Shield (c. 600,000 km²), commissioned by the Saudi Geological Survey (SGS) with International Geoscience Services (IGS) as Lead Technical Partners (TPs), and conducted by the Chinese Geological Survey (CGS) including analyses of 76 elements for each sample have been completed successfully.

More than 88,000 stream sediment samples were successfully collected with no incident or LTI (Loss Time Injury) recorded since March 2022. This is a great achievement for the team (SGS-CGS-TP) as well as IGS (Lead Technical Partners). As part of celebration for this milestone achievement and successful completion of the field sampling.

Thanks to the Technical Partners (TPs) for joining hands with the Management of SGS led by His Excellency, Eng. Abdullah Al-Shamrani (Chief Executive Officer/President of SGS) and the Management of China Geological Survey (CGS) for collecting the samples.

Members of the Technical Partner team together with staff from SGS and CGS, collect the final sample of more than 88,000 stream sediment samples within the Arabian Shield. These samples are analysed for 76 elements aiming to create a state-to-the are database and produce geochemical maps.

IDPeX and MSA meet in Riyadh to discuss our project in India


IDPeX and MSA have been working together on a project for OMC (Odisha Mining Corporation Limited) to provide exploration related support and technical assistance for mining blocks in Odisha, to be auctioned by the State Government.

IDPeX is an Indian registererd consultancy that brings together the resources of IGS, PGW and Datacode. MSA is the contractual lead on the project and brings its valuable experience in mineral exploration. Because we all attended the Future Minerals Forum 24, in Riyadh, we took the opportunity to meet after FMF 24 to discuss progress on the project and to agree on further planning. A successful meeting and many thanks to all who attended.

Workshop on high-resolution Geochemical Survey of the Arabian Shield (GSAS) using stream sediment and heavy mineral concentrate samples


Dr Esko Korkiakoski, the new IGS Team Leader for the Geochemical Survey of Arabian Shield (GSAS) gave the opening presentation at a recent two day open session workshop held at Swissôtel Living Jeddah Hotel on 17-18 of September 2023.  He outlined the current status and objectives of the survey. During the session of the workshop, China Geological Survey (CGS) (the technical operator of the field sampling, analytical work and map production) presented about 90,000 stream sediment samples.

IGS Ltd and Geological Survey of Finland (GTK) are  technical partners to Saudi Geological Survey (SGS). They are in charge of the quality control of the geochemical survey, giving support and advice in all aspects related to the project implementation, and approval of the final products.

Dr Feargal Murphy presentation to experts from Arabian Shield Stratigraphic Commission


Dr Feargal Murphy  recently presented initial results from SGS RGP airborne geophysics phase 1 (mag/rad) to experts from Arabian Shield Stratigraphic Commission (ASSC) group. The ASSC is a panel of international experts in Neoproterozoic geology who are developing an updated lithostratigraphy for the upcoming Arabian Shield mapping programme. The RGP phase 1 data is being acquired for SGS by Sander Geophysics Ltd and Xcalibur Multiphysics. IGS and colleagues from Patterson Grant and Watson (PGW) are technical advisors for the RGP geophysics programmes. IGS and GTK are technical partner for the RGP programme.

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.

Mozambique MAGTAP project – Field programme begins

The field programme for the geological mapping project was started with a kick-off workshop in Maputo (3 & 4 June 2019). The workshop took place in the lecture hall of the Museum of Natural History in Maputo.  The field programme commenced on 8 July with the first field campaign running until 10 August. Two more campaigns are scheduled for 2019. Presenters were Christoph J. Dobmeier (IGS), Stephen Reford (PGW, first row, left), and Frederick Hartzer (IGS, addressing the audience). Other attendees were staff from INAMI, DNGM, and the University of Maputo, the MAGTAP technical supervision team (Hannu Makitie and Esko Korkiakoski, first and second from right), and representatives of private companies.
