Uses of hyperspectral data

TerraCore’s method of automated imaging of drill core is a non-destructive technique that can assist in the objective and consistent logging of drill core. The spectral features, identified and monitored in the dataset, can be used not only to identify mineralogy, but to observe subtle variations occurring within spectrally responsive minerals, which may have widespread implications for orebody and alteration modelling, and geometallurgy. In addition to this, image data may be used as a tool to assist core logging, as well as geotechnical logging.

Our image and data products have a wide spectrum of applications:

  • Geological characterisation
    • Rock correlation
    • Mineral paragenesis
    • Overall increased geological knowledge
  • Mineral exploration 
    • Alteration/mineral facies mapping
    • Known deposit characterisation
    • Definition of vectors to mineralisation

  • Geometallurgy
    • Geozone classification
    • Gangue and alteration mineral definition
    • Ore zone delineation
  • Geotechnical logging
    • Core condition
    • Fracture frequency and filling

Hyperspectral Products

TerraCore offers a wide range of products which are customized to the client’s needs. Some common products include:

  • Natural and False Color images
  • Enhanced images (e.g. texture images, spectral wet, etc.)
  • Spectral features
  • Mineral maps
  • Spectral indices
  • Mineral indices
  • Digital data (e.g. statistical data by borehole depth)

Image products are generated in industry standard formats, including BIL (band interleaved by line), jpeg, and tiff, while digital data are produced as CSV or text files. This allows our clients to import, query, and model their data in most commercially available image processing and 3D modelling software packages. In addition to this, all data are made available in TerraCore’s data visualization platform, IntelliCore.
