Press Release:
oreXpress™ with EZ-ID™ real-time mineral identification for illite, malachite, azurite, and other associated copper minerals

Lawrence, MA – May 17, 2016 – oreXpress™ spectrometer with EZ-ID™ software can provide critical real-time mineral identification for key pathfinder minerals in copper exploration including illite, malachite, and azurite.

The oreXpress field NIR spectrometer running EZ-ID with two spectral libraries (USGS and SPECMin™) can identify secondary copper minerals found in oxidized zones of copper bearing ore deposits.

Using the two EZ-ID libraries and focusing on spectral features of interest by selecting different match regions, illite can be identified by its primary absorption features at 1410, 2215, and 2340nm. Malachite is distinguished by a doublet absorption feature between 2180-2300nm, and azurite with a very deep doublet feature between 2241-2420nm.

The identification of the mineral assemblages within these zones can help to target the most promising locations for drilling and focus additional investigation on those areas most likely to yield an economically viable copper deposit. The oreXpress spectrometer delivers:
• Rapid data/spectra collection in the field
• High resolution/high sensitivity for accurate reflectance values
• Fast start-up and use with no optimization step required between scans
• Sturdy construction to handle field conditions
• Reliability with no moving optics and a robust metal clad 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

EZ-ID features:
• Fast and accurate identification of an unknown mineral to a known library sample
• Ease of use – just collect a target scan and see immediate match results in real
time on your laptop
• Simple, consistent user interface
• Include or exclude spectral regions of interest for optimal results
• Fast scanning for optimum field work or core shack logging

With our Custom Library Builder software module, EZ-ID allows you to scan known samples and quickly build a custom library for a particular project, mineral, location, and more. You can select pre-defined metadata fields or define your own.
