The Geological Survey of South Australia (GSSA) offers access to mineral drilling and associated data, such as geochemistry, in a wide variety of options via SARIG (South Australian Resources information Gateway).
Mineral drilling and geochemistry datasets are extracted from SA Geodata, the primary repository for geoscientific information in South Australia, and contains data:
- from research and fieldwork conducted by GSSA staff
- by research institutions from analysis of core and rock samples held in the South Australia Drill Core Library
- submitted from industry exploration programs.

SARIG map – Mineral drillhole spatial search
The SARIG map spatial search allows users to search SA Geodata for all mineral drillholes located in a defined area. Due to the large volume of state-wide drillhole data, the defined search area is limited to 4x4 degrees. Data packages are downloaded as a zip file that contains data in .csv format and includes:
- drillhole details (including drill type)
- stratigraphy, petrophysical, lithology and geochemistry
- Core Library reference
- report references.

SARIG map – 250K mapsheet drilling and geochemistry data packages
To complement the GSSA 1:250 000 digital map series, pre-competitive drilling and surface sampling data packages can also be downloaded from the SARIG map. Data packages are downloaded as a zip file that contains data in .csv format and includes:
- drillhole details, stratigraphy and geochemistry
- surface and calcrete geochemistry.

SARIG catalogue – SA Geodata database extract
The SARIG data package is an extract of SA Geodata as series of data files in .csv format.
The database extract includes:
- basic drillhole metadata for over 300,000 drillholes, geological and petrophysical logging, and referencing information
- field observations and surface geological observations, and measurements for almost 88,000 locations
- results of rock sample analyses for over 3,000,000 rock samples collected down drillholes or from the surface, including sample and analysis metadata, geochemistry, geochronology, biostratigraphy, and petrographic analysis
- the location and description of over 9,000 mineral deposits and occurrences.
The SARIG data package file structure.pdf report can also be downloaded and provides information on how the files can be linked together as a geoscience relational database.
Data packages are updated yearly (June/July) by the GSSA.
SARIG map – MaxDH geochemistry
The GSSA has developed a suite of state-wide datasets of maximum downhole geochemistry. The maxDH geochemistry spatial datasets consist of drillhole locations, sample depths, analysis method, and sampled geochemical data transformed from single element values normalised to times average crustal abundance.
Selected elements include copper, gold, iron, silver, lead, zinc, nickel, uranium, cobalt and lithium.
Datasets are updated monthly from SA Geodata.

Quality control and standards
Quality control and standardisation of the geochemistry data has been applied such as the removal of problematic units and analytical methods, all analytes transformed into elements, units to ppm and conversion to string values. It is recommended to read the metadata lineage or readme files to gain further information.
SARIG map – Custom geochemistry data packages
The custom geochemistry tool is available via the SARIG map main menu, with the ability to create custom geochemistry downloads. Users can select up to 10 analytes with the option to filter by sample source and/or bounding coordinates. This tool provides seamless access to state-wide geochemistry in a standard wide file format that can be easily imported into third-party software.
SA Geodata contains extensive geochemical information and therefore large spatial exports may exceed the maximum limit of records that can be viewed in Excel or Notepad. If this is the case, the data export will be split into multiple .csv file format.
