Spectral Geoscience personnel use infrared spectroscopy as a tool to generate qualitative and quantitative mineral information to support the objectives of exploration geologists, mine geologists, geotechnical engineers, geometallurgists and environmental geoscientists.
Global provider of:
- Hyperspectral mineral characterisation services to the exploration and mining industry.
- Sales, support and training for The Spectral Geologist(TSG) software, and
- Delivering geo-spectral-spatial information from your field and drilling programs.
Spectral Geoscience use ‘infrared spectroscopy‘ as a versatile analytical tool to aid geologists, geotechnical engineers and geometallurgists with characterising the infra-red active mineralogy in geological materials.
Qualitative and quantitative mineral information can be extracted from:
- Diamond drill core,
- Reverse circulation chips,
- Pulps,
- Surface grab samples,
- Trench samples,
- Blast chip samples,
- Geometallurgical samples, and
- Samples collected for environmental assessment and remediation purposes.
BENEFITS
Rapid, non-destructive, objective identification of infrared-active mineralogy.
– Rapid: hyperspectral measurements can be acquired in seconds, resulting in hundreds of field samples analysed per day with a hand-held spectrometer and up to ~500 m per day with a HyLogger (hyperpectral core logger). Generates a timely turn-around to make informed decisions of where to drill next (and just as importantly where not to drill). Saves unneccessary expenditure and time. Reduces risk.
– No sample preparation is required other than ensuring the sample is dry and clean (i.e. clear of drillers mud etc).
– Objective logging of mineralogy: delivers consistent logging of mineralogical variables (e.g. species, abundance, crystallinity and chemistry) across a deposit.
– Identification of alteration mineralogy: infrared spectroscopy is sensitive to the molecular bonds in a mineral lattice and can readily identify minerals that are often too fine grained, bleached or texturally destroyed to be recognised by eye, even with a hand lens.
– Rapidly produce logs/maps of mineral abundance, alteration intensity and compositonal substitution (e.g. Al-Fe/Mg in white micas and Fe-Mg in chlorites).
– Increases the effectiveness and efficiency of geological core logging. Used as a tool to support, improve and complement conventional logging.
– Identify mineralogical vectors to ore based on distal-proximal mineral alteration zonation and relationship to mineralisation.
– Integratable mineral results formatted as spatially georeferenced and/or depth registered alpha-numeric variables to facilitate interpolation between surface samples or drill holes; integration with multi-discipline datasets; and interogation in 3D mine modelling or GIS software.
– Generates interoperable mineral map/log products: mineral results can be used multiple times throughout the mining chain, from exploration-development-extraction-remediation.
– Generates geological insights to further the understanding of current deposits and assists in determining the mineral exploration potential of new prospects.
Infrared spectroscopy value-adds to the investment in drilling and leads to increased efficiency, knowledge and productivity.
