Global provider of:
- Hyperspectral mineral characterisation services to the exploration and mining industry.
- Sales, support and training for The Spectral Geologist (TSG) software.
Delivering geo-spectral-spatial information from your field and drilling programs.
Identifying the mineralogy in geological samples is a primary objective and foundational component across the geoscientific disciplines of the exploration-mining-geometallurgy-remediation chain.
Spectral Geoscience 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 an environmental scientists.
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
- RC chips
- Surface grab samples
- Trench samples
- Blast chip samples
- Geometallurgical samples
- Samples collected for environmental assessment and remediation purposes.
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.
What we do
We are passionate about the application of hyperspectral mineral analysis to aid exploration and mining companies identify, delineate, develop and extract natural resources.
We listen to our clients
To find out what their challenges are, then collaboratively plan a tailored scope of work using the appropriate tool for the task.
hyperspectral Data acquisition
1. HyLogger-3 (VNIR-SWIR+TIR)
2. ASD TerraSpec4 or Halo (VNIR-SWIR)
SpectralGeo can capture hyperspectral infrared data on-site or in the field using a hand-held infrared spectrometer (e.g. TerraSpec4, Halo, oreXpress) and/or train clients in how to obtain their own high quality spectra.
Alternatively, clients can send their samples to SpectralGeo to be scanned and analysed.
SpectralGeo can also arrange for larger projects to be scanned by one of several CSIRO-developed HyLoggers around Australia and in China, Mexico and Chile.
Extract qualitative or quantitative mineral information including: mineral identification, abundance, crystallinity and chemistry. Deliver mineral products fit-for-purpose to meet the client’s needs.
What our customers say
TerraSpec4 + TSG onsite training in data acquisition and analysis.
“I am VERY happy with the results. We are going to zap every drill hole from now on.”
Mineral characterisation of drill core samples collected with an oreXpress.
“….your interpretation of the alteration mineralogy is one of the more important strands of information that we can get from the drilllcore and we don’t want to waste any precious drilling meters!”
