First in Full Range PDA Spectrometer, Spectroradiometer and Spectrophotometer Systems
oreXpress Full Range, Field Portable Spectrometers for
Mineral Identification and Analysis
The oreXpress spectrometer and EZ-ID software are trademarks of Spectral Evolution, Inc.
The oreXpress spectrometer delivers the benefits of a
full range NIR spectrometer to the geologist in the field.
The oreXpress makes mineral identification fast and
efficient. It is used for:
  • Mapping alteration zones
  • Vectoring to mineralization
  • Open pit mapping
  • Analyzing outcrops, hand samples, and RC chips
  • Quickly analyzing drill core samples
The oreXpress saves spectra as ASCII files and works
with third party software such as:
  • SpecMIN
  • TSG

    detectors covering the 350-2500nm spectrum
  • High signal-to-noise ratio for better reflectance values
  • Fast start-up and use, with no optimization step required to
    start scanning or between scans
  • DARWin SP Data Acquisition software automatically saves
    scans as ASCII files - no hours of pre-processing to use with
    3rd party software
  • Collect target data with a single click
  • Mineral identification capabilities are built-in - use our EZ-ID
    software, compare scans versus existing libraries such as
    SpecMIN, USGS and GeoSPEC high resolution library or
    compare against your own custom libraries
  • Scalars that provide better understanding of geochemical
    conditions at alteration
  • Our library builder allows you to quickly build new libraries
    and add to existing libraries
  • Rugged handheld GETAC PS336 handheld microcomputer with
    a sunlight readable display includes an auto-focus digital
    camera, e-compass, altimeter, GPS and voice notes, as well as
    the ability to tag  scans with pictures, notes GPS, etc.
  • Ergonomic mineral contact probe and rugged metal clad fiber
  • Lightweight lithium-ion battery for power in the field
  • A range of accessories

SPECTRAL EVOLUTION mining customers range from some of the
world's largest to junior miners, including Rio Tinto, Trafigura, and
Mineral Targeting and Exploration, to name a few.

Geologists and exploration managers can identify minerals
associated with
gold, silver, iron, copper, diamonds, aluminum,
uranium, and more across a range of deposit types, including
epithermals, porphyries, kimberlites, carbonate hosted base
metals, shear veins, skarns, and disseminated gold systems.

In addition to in situ measurement and
identification in the field, these
geological spectrometers are also ideal                                              
for core shack logging. In fact, in one
application, core logging analysis
was cut from six hours to just two
The GETAC PS-336
handheld microcomputer
can be used to
tag spectra with GPS
readings, photos (with its
built-in digital camera) and
voice notes with its built in
microphone. In this image,
the PS336 was used to
identify the presence of
montmorillonite. The extra
bright VGa display can
even be viewed in direct

oreXpress Spectrometer
  • Ideal for field
    measurements on pits,
    hand sample analysis, chip
  • Also ideal for core logging
    in logging shacks
  • External battery for field
Field cart for core logging applications.
For core shack use, we also offer a
foldable field cart or a lightweight
plastic tall field cart with three

EZ-ID Software

The oreXpress spectrometer is available with EZ-ID software that
  • An easy way to create a custom mineral library
  • The ability to quickly add spectra to an existing library
  • Pattern matching algorithms in interactive mode that can
    be used with SpecMIN, USGS and GeoSPEC high resolution  
    libraries for mineral identification
  • Display of your match report on-screen  
EZ-ID builds mineral identification capabilities into the oreXpress.
You can quickly identify the mineral, compare it against an
existing general library like the USGS, SpecMIN, GeoSPEC High
Resolution library or match it to the custom library that you have
built with EZ-ID.
