Spectral Evolution said its oreXpress spectrometer with EZ-ID software can provide critical real-time mineral identification for key pathfinder minerals in lithium exploration, including lepidolite and spodumene.

The oreXpress is a high-resolution/low-noise NIR spectrometer that covers the 350-2500 nanometer range and is designed for field use. With the accompanying contact probe, a geologist can quickly collect scans from outcrops, trenches, pits, walls, even cores and chips to identify alteration minerals, according to the company. The oreXpress field NIR spectrometer running EZ-ID offers two spectral libraries (USGS and SPECMin) to identify lepidolite and spodumene in pegmatites. The libraries include 1,500 spectra for 600 minerals. Using the two libraries, EZ-ID will match unknown sample scans against scans from the library. The software allows a geologist to focus on key spectral features of interest by selecting different match regions within the full scan and matching to those features. The analysis results can be quickly saved to a spreadsheet file for comparison of different matches. All data is saved as ASCII files for use with additional third-party software tools like TSG, GRAMS or 3-D mapping and analysis programs.
