Spectral Evolution oreXpress, oreXplorer, oreXpert Portable Spectrometers

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.

The oreXpress provides quick reliable mineral analysis with a standard resolution of 3nm.
The oreXplorer delivers higher resolution and sensitivity for identifying hard-to-unmix minerals with similar features.
The oreXpert is the highest resolution spectrometer on the market. Its 1.5nm resolution allows the distinction of features that help with unmixing and identification of trace minerals.

RESOURCES

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- optimiSation on every scan
Portable, lightweight unit with optional Mesa 3 tablet – easy for one person to use
Mesa 3 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
