Field Portable NIR Spectrometers for Mineral Identification and Analysis in Mining Exploration

With Spectral Evolution field portable NIR spectrometers and EZ-ID mineral identification software, geologists can measure and identify minerals within seconds and cover more ground than by using traditional methods. They can identify different mineral phases, create mineral alteration maps and more accurately identify mineral pathfinders for vectoring to ore deposits. Spectral Evolution's field portable, battery-operated oreXpress, oreXplorer and oreXpert ultra-high resolution NIR spectrometers are designed for mineral identification in mining exploration. The oreXpress, oreXplorer and oreXpert provide quick payback with faster, more accurate mineral identification in exploration for gold, silver, diamonds, iron, nickel, copper, uranium, aluminum - in the field, core shack, or in the lab, and provide:

  • Rapid data/spectra collection in the field - allowing you to take more scans in less time
  • High resolution in a field instrument
  • High signal-to-noise ratio for improved reflectance values
  • Fast start-up and use with no optimization step required between scans
  • Sturdy construction for harsh field environments
  • Reliable operation with no moving optics and a robust fiber optic cable with quick-disconnect
  • Rugged and reliable mineral contact probes for single click field measurements to measure outcrops, cores and chip trays

Using our portable UV/VIS/NIR reflectance geological spectrometers, you can identify:

  • Al(OH) group minerals
  • Sulphates
  • Si(OH) group minerals
  • Fe(OH) group minerals
  • Mg(OH) group minerals
  • Carbonate group minerals
  • Selected OH-bearing silicates
  • Selected zeolites
  • Selected rare earth element (REE)-bearing minerals
  • Selected massive sulphides

oreXpress, oreXplorer and oreXpert NIR spectrometers provide a number of unique, in-field benefits, including:

  • Full UV/VIS/NIR spectral range of 350-2500nm
  • Fast scanning and ease-of-use - one touch operation, auto- optimization on every scan
  • Portable, lightweight unit with optional rugged handheld tablet - easy for one person to use
  • Your tablet becomes your field notebook - record audio notes, add your GPS position, take pictures of your samples, save it all and tag it to your scan
  • Rechargeable lithium-ion batteries- lightweight, four hour operating life
  • Immediate start-up - no warm up - start taking readings immediately to take advantage of daylight and weather
  • DARWin SP data acquisition software collects your critical data, saves in ASCII files - no post-processing necessary - use with SpecMIN, GRAMS, TSG, Unscrambler from Camo Analytics and other 3rd party software

Field Portable Spectrometers for Mining

  • Spectral Evolution field spectrometers

    • Ideal for field measurements on outcrops or mapping open pits, hand sample analysis, chip trays
    • Also, ideal for core logging in logging shacks
  • The oreXpress, oreXplorer and  oreXpert spectrometers are well-suited for core logging where they can increase your productivity by taking more scans in less time. For core shack use, we also offer a choice of field carts: a collapsible field cart or a lightweight plastic tall field cart with three shelves.

  • SPECTRAL EVOLUTION spectrometers are ideally suited for mining exploration, mineral identification, and mining production. These spectrometers cover the UV/VIS/NIR spectra using three photodiode arrays with no moving parts. This makes them supremely reliable in the field. They can collect spectra in as little as 100 milliseconds. The instrument control and data handling DARWin SP Data Acquisition Module included with each unit provides full featured software and is compatible with a wide range of 3rd party analytical software, including: SpecMIN, GRAMS, The Spectral Geologist (TSG), Unscrambler from Camo Analytics and others.

    EZ-ID Software

    Our oreXpress NIR spectrometers are available with EZ-ID software that provides:

    • Fast and accurate identification of an unknown mineral to a known library sample
    • Easy-to-use, just collect your scan and see the results in real time
    • Simple, consistent user-interface
    • Pattern matching algorithms in interactive mode that can be used with SpecMIN, USGS, GeoSPEC and other libraries for mineral identification
    • Software provides a weighted score for best matches
    • Include or exclude spectral regions of interest for optimal results and display results and scores in multiple columns in different combinations for comparison and unmixing
    • Save match regions as pre-sets to facilitate looking for similar minerals
    • Scalars that provide additional information on alteration
    • The ability to create your own library of known samples and the option to import and convert ASD files for use with EZ-ID
