IGS is working in Collaboration with GeoOptimist
IGS (International Geoscience Services) Ltd, a leading provider of earth-based intelligence to governments worldwide, is delighted to collaborate with GeoOptimist to advance mineral exploration and geological mapping services. This collaboration brings together complementary strengths in geology, remote sensing, and geospatial analysis, enhancing both companies’ capabilities in mineral targeting and resource evaluation.
Together, we offer proven expertise in delivering high-quality data and geospatial insights that support and enrich geological investigations in the following areas:
Geological Mapping
Advanced image processing techniques—including custom band combinations and mineralogical band ratios—to highlight key lithologies and mineral distributions. Multispectral and hyperspectral data are used to map geological formations, locate potential mineral deposits and interpret surface geology.
Advanced Image Processing
Data reduction methods, including Principal Component Analysis (PCA), and classification approaches—both supervised and unsupervised—are used to enhance feature extraction. These techniques support improved lithological interpretation and structural analysis.
GIS Data Management and Map Production
Comprehensive GIS support includes data creation, cleaning, database structuring and managing, and metadata documentation. High-quality, client-specific map products are produced using standardized workflows and robust spatial data management.
QA/QC in Remote Sensing
A systematic QA/QC process ensures the accuracy and consistency of remote sensing data and preprocessing steps. These quality measures are critical for delivering reliable inputs to geological mapping and exploration workflows.
This collaboration blends strong geological expertise with technical excellence in geospatial science. Our combined capabilities offer a reliable and flexible resource for exploration teams and government agencies seeking trusted geoscience support.

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.

IGS welcomes new Mapping Geologist
IGS is pleased to announce the arrival of a new member of staff to our team, Dr. Reik Degler.
Following an MSc in Economic Geology at the Freiberg University of Mining and Technology in Germany and a PhD in Tectonics at the Federal University of Minas Gerais in Brazil, Reik has gained considerable geological experience at international level. Beside his research at the Institute of Geosciences during the PhD, he participated as a leading geologist in joint regional scale geological mapping projects on mineral occurrences potential between Brazilian State Governments and the Geological Survey of Brazil.
Reik has been appointed as a Mapping Geologist and will initially be working on our project in Mozambique.
On joining IGS, Reik said “I am very happy to join IGS and look forward to applying my skills in international projects and contributing my part to the continued growth and development of IGS”.
Peter Zawada, Managing Director of IGS, commented “IGS warmly welcomes Reik whose experience will provide very useful contributions to the company’s current and future projects.”

Completion of the Cameroon Supervision Geology Project
IGS supervised the implementation of the three main components of the project included geological mapping of 13 map sheets at a scale of 1:200 000, collection and analyses of about 18,500 geochemical samples from the same area and the construction of a national GIS-based database (information system) which will contain all relevant geological information for Cameroon.
IGS assisted Precasem in Cameroon to define the project, wrote the Terms of Reference and assisted them in the evaluation of tenders and the appointment of a consultant. In addition to the role of quality control of the 3 sub-programmes IGS also assisted Precasem in the development of a data management and dissemination policy for the new National Geological Database.

MAGTAP project underway in Mozambique
In October 2018, a group of geologists from the four consortium partner organisations (BRGM, Gondwana, IGS, and Mozambique’s Instituto Nacional de Minas (INAMI)) travelled to Nampula Province. Under the leadership of Dr. Frik Hartzer (IGS) and Joao Marques (Gondwana) the team met with officials of the provincial administration and local authorities, and performed a detailed logistical and geological assessment of the field situation. This exercise formed an invaluable part of the ongoing preparation for the field programme, which will start in the second quarter of 2019.

IGS and the Geological Survey of India
IDPeX (which is a joint-venture partnership between IGS, PGW of Toronto and Datacode Intl. of Nagpur, India) has recently completed tender supervision and quality control (TSQC) of Blocks 1,2 and 4 of the Geological Survey of India’s (GSI) OGP Year 1 multi-sensor airborne geophysical survey programme. This forms part of India’s national high resolution geophysical program of ‘Areas of Obvious Geological Potential’ that covers an area of 813 000 km2. IDPeX presented a review of its Year 1 work at a recent workshop held at GSI, Bangalore.
IDPeX has been working closely with GSI and PIAs (Project Implementation Agencies) throughout the Y1 programme and the results provide a modern high resolution database for use by mineral exploration and other sectors.
IDPEX has also recently signed a contract with GSI for the interpretation of legacy data and consultancy in setting terms of reference for new detailed surveys in areas of specific mineral exploration interest.

IGS attends World Mining Congress in Astana
IGS recently attended the World Mining Congress 2018 in Astana, Kazakhstan.
This event, held every 3-4 years, brings together personnel from the mining industry, as well as governmental representatives, geologists, engineers and other industry professionals to discuss and debate ongoing issues.
IGS also attended meetings with senior Kazakh governmental representatives including from the Committee of Subsoil Use and KazGeology, as well as Nazerbayev University. The meetings sought to progress discussions concerning the ongoing geoscience requirements of the Kazakh authorities within a ‘Geocluster’, or Competence Centre of Geology.
Commitments from the Committee were confirmed, and solutions discussed to support the financing of the Centre. Further progress is expected to be made later this year, with the work supported from the UK side by the Department of International Trade (DIT).
