Portable Oscilloscope serves mining exploration and production.

Press Release Summary:

Built for single-user operation in field, oreXpress™ full range UV/VIS/NIR/SWIR spectrometer delivers performance required to identify minerals. Lack of moving optics as well as MIL-spec fiber optic cable connector with easy-disconnect fiber promote reliability, and optimization step is not required between scans. Mineral contact probe allows for single-click field measurements as well as use in core logging shacks and with chip trays. EZ-ID software is also available.

Fast, Accurate, and Actionable Analysis for Mining Exploration and Production

Introducing the oreXpress™ spectrometer fromSPECTRAL EVOLUTION.See the oreXpress at Spectral International Booth 115 at SEG Whistler, September 24-27, 2013.

Lawrence, MA – SPECTRAL EVOLUTION introduces the next generation of spectrometers for mining exploration and production: the oreXpress™ field, portable spectrometer.

Like all SPECTRAL EVOLUTION field spectrometers, the oreXpress spectrometer is purpose-built for efficient single user operation in the field – lightweight, compact, easy-to-use, and ultra-reliable. As a full range UV/VIS/NIR/SWIR spectrometer, it delivers the high performance required to identify minerals for gold, silver, iron, copper, diamonds, aluminum, uranium and more. The affordable oreXpressoffers a range of benefits, including:

• Rapid data/spectra collection in the field

• High signal to noise ratio for improved reflectance values

• Fast start-up and use with no optimization step required between scans

• Sturdy construction to handle field conditions, including high ambient temperatures

• Reliability with no moving optics and a robust MIL-spec fiber optic cable connector with easy-disconnect fiber

• A rugged and reliable mineral contact probe for single click field measurements, use in core logging shacks, and with chip trays

The oreXpress spectrometer is available with SPECTRAL EVOLUTION’s EZ-ID software that provides:

• 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 the SpecMIN, USGS, and other libraries

• Display of your match report on-screen

Equipped with the oreXpress spectrometer, geologists, field technicians, and exploration managers can:

• Collect a soil grid and establish a baseline

• Map alteration zones

• Vector to mineralization

• Open pit mapping

• Analyze outcrops, hand samples, RC chips, and blast holes

• Analyze drill core quickly and efficiently

• Perform ground truthing for remote sensing images and data

In addition to in-the-field tasks, data collected with the oreXpress spectrometer issaved as ASCII files for use with third party analysis software, without requiring time-consuming pre-processing.

The oreXpress spectrometer with companion Getac PS336 handheld microcomputer features:

• 350-2500nm spectral range

• Auto dark shutter and autoexposure for easy, one-touch scanning

• No optimization required to start scanning – get to work as soon as you hit the field

• Thanks to the Getac PS336, easily tag spectra with images fromthe auto-focus digital camera, e-compass, altimeter, GPS data, and voice notes.

• Getac sunlight readable VGA display

• Mineral contact probe with metal-clad fiber optic cable

• Lightweight LI-ion batteries for power in the field

• Accessories include core shack fold-up field cart and benchtop reflectance probe
