TSGTM is the  market-leading, industry standard software program for the  interactive analysis, visualisation and mineralogical interpretation of VIS/NIR/SWIR/TIR reflectance spectra. TSG digitally transforms geological samples into mineralogical information products.

Qualitative and quantitative mineral results generated in TSG improve geologists’ efficiency, productivity and knowledge-base, leading to actionable insights and informed decision-making.

TSG works directly with hyperspectral data collected from drill core, chips and field samples acquired by:

  • Hand-held infrared spectrometers (e.g. Malvern Panalytical ASD’s TerraSpec® and Halo, Spectral Evolution’s oreXpress and the ARCoptix infrared spectrometers.
  • HyLogger systems, the CSIRO-developed automated imaging and hyperspectral core logging systems, located in each Australian Geological Survey, commercially available for international deployment through Corescan Pty Ltd.

Developed by geologists, for geologists. TSG supports multi-disciplinary geoscientific endeavours across the exploration-mining chain.

TSG is developed by, and marketed under license from, the Commonwealth Scientific Industrial Research Organisation (CSIRO). Spectral Geoscience is a CSIRO authorised sales affiliate of TSG. New timed licensing and pricing options provide flexible options for TSG users to manage the timed access according to project and company needs, removing the upfront costs of software ownership. TSG subscribers receive the latest TSG software updates as they are released.

Melissa Quigley is Spectral Geoscience’s Principal Spectral Geologist and is a leading specialist in the operation, application and training of TSG to address industry related challenges across the exploration-mining value chain. Melissa is proficient in the analysis of VNIR-SWIR+TIR data in TSG and contributed to the development of TSG during her 15 years working at CSIRO Mineral Resources. TSG continues to be developed by CSIRO and Melissa retains a close association with the organisation as a TSG beta tester and authorised sales affiliate.

More about TSG™

Identifying the mineralogy in drill core, chips, soils and grab samples is a primary objective for successful mineral exploration, mine planning and development, geometallurgical flow sheet design and environmental-remediation practices. TSG supports geoscientists at each step in the exploration-mining value chain by providing rapid characterisation results of infrared-active mineralogy to generate actionable insights. Complimentary datasets such as assays, lithology logs and down-hole geophysical results, can be imported to evaluate the spatial relationships with the spectro-mineralogical results generated in TSG. TSG can process thousands of spectra on-the-fly and rapidly generate mineral information critical for the characterisation of the regolith, host rock and alteration associated with ore deposits. TSG is designed for the interactive analysis and visualisation of infrared spectra, mineralogical results, associated imagery and ancillary data. Users are provided with several analysis options for extracting mineral information from infrared spectra. These range from a first-pass automated interpretation using built-in algorithms to more sophisticated scalar-based tools for the experienced user. NEWLY RELEASED TSG Version 8 contains:

  • New functionality.
  • New algorithms for the automated interpretation of spectra (TSA+ for the SWIR and jCLST for the TIR).
  • Improved spectral libraries.
  • Enhancements to take full advantage of VNIR-SWIR+TIR data collected with HyLogger hyperspectral core logging systems.

Results generated from TSG can include:

  • Mineral identification
  • Relative abundance
  • Crystallinity
  • Compositional changes within a mineral group (e.g. Al-Fe/Mg in white micas and Fe-Mg in chlorites).

Products generated can include:

  • Down-hole, depth-registered logs of mineralogy and associated attributes (alpha and numeric formats).
  • Scatter plots and histograms saved as JPG, PNG, EMF and TIF.
  • CSV files exported for easy integration with third party software. Down-sampling optional (e.g. 2m composites).
  • HyLogger imagery export of automatically configured and labelled core trays and mosaics of core trays per drill hole.

TSG is a 64-bit Windows based software program.

TSG version 8 replaces all earlier versions (e.g. TSG Pro, Core, HotCore and Enterprise) and bundles the previously seperated functionality into one powerful package, TSG 8. There is now only one ‘TSG’ and the free ‘ TSG Viewer’.

TSG 8 is not backward compatible. Once a dataset is opened in TSG 8, it can no longer be opened in a previous version of TSG. Learn More
