IGS (International Geoscience Services) geophysicists continue to carry out quality control and provide technical advisory services to SGS (Saudi Geological Survey) for the Regional Geoscience Program (RGP) Phase 1 geophysics which consists of magnetic gradiometry and radiometrics flown at 300m line spacing over the entire Arabian Shield.

Sander Geophysics is flying Block 1 while Xcalibur is currently flying in Block 3. Both blocks are approaching 50% completion and some final products have been generated for completed portions . There are now 7 aircraft on the project and > 700,000 line kms flown to date. IGS and partners have also assisted the Saudi Geological Survey with developing scope of work for future airborne acquisition phases comprising targeted surveys (e.g. electromagnetics) over areas prospective for mineral deposits.

IGS was privileged to showcase the company and its services at the large UK Department for International Trade (DIT) stand at Mining Indaba, Cape Town, 6^th to 9^th February 2023. We received a lot of interest and enquiries with Indaba this year being better attended and having  more of a ‘buzz’ than 2022. Certainly, and as always, it was a pleasure to meet up with clients, partners and colleagues.

Dr. Peter Zawada (MD) gave a presentation at the DIT stand entitled ‘Increasing Nation States competitively in the Mineral Sector’. Dr. Ash Johnson (COO) and Dr. Frik Hartzer (Senior Project Manager) of IGS also attended Indaba. It was particularly pleasing to meet up with Government Ministries and Geological Survey officials from across the world under one roof.

The Saudi Geological Survey have announced the launch of a new committee that brings together international geological experience from the Saudi Arabia, the US, Australia, Europe and China to take a modern look at structures across the Saudi part of the Arabian-Nubian shield.

Luke Stannard process Manager at Resolve Mining Solutions | Board Member of the Australia Saudi Business Council indicated that some regions have not seen review for over 50 years. He said he has often come across reports that appear to need a new eye cast over them and this will lead to a few new discoveries/interesting exploration programs.

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) and conducted by the Chinese Geological Survey (CGS) is currently in its second sampling phase.

Since GSAS started at the end of 2021, the project has been making great strides. More than 48 000 stream sediment samples have been successfully collected and progressed by the contractor. The first analytical results are expected in the coming month. The project will have a duration of six years with the sampling and collection of approximately 100,000 sediment samples which will be completed in the first three years.

In its role as the official Technical Partner of the SGS, IGS experts supported by geochemists from the Finish Geological Survey (GTK), advise the client and undertake the quality control of the following project stages: planning, sampling, sample preparation, chemical analysis, data quality, geochemical databasing, statistical analysis of data, interpretation, and geochemical map production.
