What are you looking for? Use the oreXpress with EZ-ID to identify minerals across a range of deposit types including epi-thermals, porphyries, kimberlites, carbonate hosted bas metals, shear veins, skarns, and disseminated systems. Gold Low sulfidation deposits: illite, kaolinite, chlorite, illite/smectite, buddingtonite, epidote, montmorillonite, zeolite, quartz, calcite, hematite For high sulfidation: alunite, opal, dickite, pyrophyllite, diaspora, zunyite, topaz, illite, kaolinite, epidote, quartz, montmorillonite, goethite, jarosite, hematite For orogenic gold: muscovite, paragonite muscovite, roscoelite, illite, kaolinite, quartz, siderite, ankerite, calcite, dolomite, carbonates Copper Porphyry copper: tourmaline, muscovite, alunite, kaolinite, jarosite, goethite, hematite, chalcanthite Oxidized BXA (leach cap): mica, jarosite, alunite, kaolinite Oxidized phyllic: alunite, kaolinite, jarosite, copper sulfate overprinting muscovite Potassic: muscovite, tourmaline, some alunite Nickel Nickel in lateritic ore deposits: nickeliferous limonite, goethite, smectite, nontronite, garnierite Uranium Uraninite, sericite, dickite, chlorite, kaolinite, illite, pyrite, chalcopyrite The oreXpress and oreXpress Platinum save your scans as ASCII files for use with 3rd party software such as: GRAMS is a software suite for visualizing, processing, and managing spectroscopic data. It offers tools to capture, store, process, and report data, plus a graphical multivariate analysis tool for qualitative and quantitative analysis. TSG™ is a tool for geological analysis of spectral reflectance data of minerals, rocks, and soils, including drill cores and chips. With this software you can organize all your data as part of a project data set for more effective analysis.

An essential tool for successful mining exploration and production oreXpress™ and oreXpress Platinum spectrometers deliver the benefits of a full range NIR spectrometer to the geologist in the field. With oreXpress, geologists can get an accurate idea of what they are looking at, quickly scan samples, and cover more ground in less time and at less expense than using traditional field methods. They can identify different mineral phases, work up forensics on an area, and understand more clearly what’s there. With EZ-ID™ real-time mineral identification software, oreXpress facilitates identification of critical alteration minerals for better interpretation and a more profitable approach to drilling. Targeting the most promising areas before drilling begins can eliminate unnecessary drilling costs and quickly pay back the investment on the oreXpress. Used in a core shack, the oreXpress can eliminate unnecessary assays on cores that show no potential and reduce the time logging takes—in one application it cut logging time from six to two hours.

EZ-/D Real Tlme Mineral ldentlf/cat/on

O O

ores,oress spectrometer packages can include the Et-/b s oftware that allows a geolpgist to compare a target scan against a spectral library /Ike USGS or Spec/WN , or build a custom, special purpose library. With EZ-ID, you can compare unknown mineral samples to a library, using various algorithms to provide more accurate matches. You can select different spectral regions dependi/7g on the minerals of interest and view a match report on screen. Above rS a sample of kaol/'nite matched against the uses library. As can be seen, the unknown sample has a match score in the bottom window of o. 984, w/'th 1. coo being an exact match. With EZ-lD, a geologist could scan and identify samples very rapid/y-this would be an exceptional tool for core shack logging as well as held measurements. AZ-/D is available with the to//o wing libraries:

uses; 466 spectra for 226 m/'nerals SpecMlN.' 1528 spectra for 494 minerals

Library Builder Module-BulldA Custom Spectral Library /n addition to matching unkno wn samples to known minerals in a commercial library, a geologist can quickly and easily build a custom library of spectra for minerals. A geologist can create a custom library for a class of minerals, a specific location, each project- whatever makes the most sense. W/'th our Library Builder, you can: 4 Scan your sample with the oreXpress spectrometer o Select the appropriate metadata associated with

this scan Define your own metadata Add new scans to your library quickly and easily Run new target scans against your library immediately
