2017 Students in Mining & Energy Instrument Support Program Winners

January 24, 2017

We are happy to announce the winners of the ASD Students in Mining & Energy Instrument Support Program!

The Students in Mining & Energy Instrument Support Program allows students from around the world interested in mining and energy disciplines to submit a research proposal involving spectral mineralogy. Winners will have the opportunity to borrow an ASD field spectrometer at no charge in order to pursue their research endeavors.

This year, we had a number of interesting geologic submissions so it is unfortunate to have to limit the number of winners that we are able to support.

ASD is quite pleased to announce the following seven global 2017 Students in Mining & Energy Instrument Support Program winners and their research topics:

ASD's October Webinar Focuses on Interpreting Geochemical Conditions on Mars

October 04, 2016

Our 2016 webinar series focuses on one ASD spectroscopy application each month.

If you haven't watched our previous webinars, please visit our webinar recordings page to see what you have missed! Some of our past webinar topics include: NIR, Metamorphic Petrology, and Remote Sensing, On-orbit Sensor Absolute Radiometric Calibration for Earth Remote Sensing, and Adventures in Albedo.

This October, our spectroscopy webinar focuses on the specific application of terrestrial analog studies and geochemical conditions and features ASD's TerraSpec® Halo Mineral Identifier

In this webinar you will learn about:

  • Terrestrial analog rover simulations using a VNIR field-portable spectrometer in remote Utah as a useful tool in refining Mars rover operational strategies
  • On being a "human rover" - science team protocols, targets of interest and data collection
  • Using terrestrial analog sites to reconstruct the geologic history of Mars
  • Investigating diverse hydrothermal deposits with Mars analog instrumentation

And now, a round of applause for our 2016 Students in Mining and Energy awardees!

June 07, 2016

Four students were selected from a group of applicants for inclusion in the 2016 Students in Mining and Energy TerraSpec Instrument Program.

Two students will be granted the temporary use of a TerraSpec® 4 Hi-Res mineral spectrometer system, which includes The Spectral Geologist (TSG®) Pro mineral analysis software. The other two students will receive temporary use of the TerraSpec Halo mineral identifier, the all-in-one mineral analysis system that allows you to immediately identify alteration minerals with a simple pull of a trigger.

Defining mineral system footprints in the Edmund Basin of the Capricorn Orogen, Western Australia

February 18, 2016

By PhD candidate MSc Heta Lampinen and supervisors; Dr Carsten Laukamp (CSIRO), Dr Sandra Occhipinti, Prof Campbell McCuaig and Prof Marco Fiorentini (CET/UWA) as part of the 2015 Students in Mining & Energy TerraSpec Instrument Program.

The project aims to discover how reflectance spectra measured from the surface of the earth can be utilised in finding mineral footprints of hydrothermal ore deposits concealed by the regolith. The scope is to identify the mineral assemblages at the study area that are characteristic for four schematic domains: 1) unweathered, unaltered bedrock, 2) unweathered altered bedrock, 3) regolith atop unaltered bedrock, and 4) regolith atop altered bedrock.

Prior to fieldwork, reflectance spectra measurements were collected in a laboratory setting (Figure 1) using FieldSpec® 3 spectrometer from 552 surface regolith samples, archived by the Geological Survey of Western Australia (GSWA) and the Commonwealth Scientific and Industrial Research Organisation (CSIRO). The acquired VNIR-SWIR reflectance spectra were processed in The Spectral Geologist (TSG®) software using the Multiple Feature Extraction Method MFEM; (Cudahy et al. 2008 and Laukamp et al. 2010) for characterisation of mineral assemblages. This work was carried out to establish the regional and deposit scale variation in the surface mineralogy in general, but also to compare the hyperspectrally derived mineralogy with geochemical analyses undertaken by GSWA to effectively target the fieldwork areas of interest.

The TerraSpec® 4 Hi-Res mineral spectrometer was used during three weeks of fieldwork from April 20th to May 10th 2015 in the Edmund basin of the Proterozoic Capricorn Orogen in Western Australia. The study area of 60*110 km in size is located 900 km north from Perth, west of the Collier Range National Park and roughly 170 km west from the Great Northern Highway. The study area is designed around the sediment hosted stratiform Pb-Cu-Zn-Ba deposit Abra, discovered at roughly 200 m depth in 1981 by drilling into a magnetic bulls-eye anomaly. Geochemical sampling efforts have so far failed to a find mineralisation footprint around the Abra deposit. Other known base metal mineralisation occurs within the same structural corridor, along the crustal-scale Quartzite Well Fault.

Asian mining company uses ASD TerraSpec analyzer to help characterize alteration assemblages in Sumatra

January 26, 2016

With ore reserves of 2.7 million ounces of gold and 27 million ounces of silver, the Martabe Mine is one of the largest in Indonesia. Looking to expand the life of the northern Sumatran epithermal gold mine, G-Resources has been conducting a regional exploration program around the mine and has identified additional epithermal deposits as well as potential gold-copper porphyry mineralization. With the additional deposits G-Resources now estimates the resource at 7.4 million ounces of gold and 70 million ounces of silver.

Calling all mining, energy or geology graduate students!

The 2016 Students in Mining TerraSpec Instrument Program deadline is November 16! 

All graduate students conducting mining, geology, energy or geothermal related research are encouraged to submit their proposals for the 2016 Students in Mining TerraSpec Instrument Program by November 16.

How does mineralogy affect comminution?

October 20, 2015

Near infrared (NIR) mineralogy is a commonly used tool used by geometallurgists to improve ore recovery in leaching and floation activities. However, it can also be used earlier in the mineral recovery process to optimize comminution. Stacey Leichliter examines how NIR mineralogy can be used to better control costs and possibly increase recovery by using NIR mineralogy to optimize the comminution circuit.  

TerraSpec mineral analyzers are everywhere - an update from SEG 2015

September 29, 2015

The SEG 2015 conference is underway in Hobart, Tasmania. This joint SEG-CODES Conference has included key presentations from leaders in research and industry on the discovery of world-class ore deposits, their geology and the recovery of metals from ores, and has covered the issues and controversies that affect exploration. With all of these presentations, posters and exhibitors it has been easy to spot the TerraSpec line of mining instrumentation.

Cassady Harraden in her general session talk today titled "Delineation of geometallurgical domains in the Pebble porphyry Cu-Au-Mo deposit, Alaska," described 'extensive application' of the TerraSpec to define four additional alteration zones (for a total of six alteration types) by describing and mapping subtle shifts in Al-OH features. At Pebble, alteration is the key to metal occurrence and variability. This TerraSpec data was used to define the 3-D alteration model and geometallurgical delineation which then optimizes mine plans, enhances project value and minimizes economic risk.

Also at SEG, 2015 Students in Mining TerraSpec Instrument Program participant Heta Lampinen presented her poster

Application Roundup: a summary of ASD instruments in action

Non-destructive fruit testing

It is becoming quite common to utilize NIR spectroscopy in the field or greenhouse to measure fruit sweetness. This is useful both for deciding when to harvest, but also when running a breeding program. The ability to rapidly and non-destructively select plants with the desired traits allows fruits on those plants to mature and have their seeds collected. A recent study goes beyond sweetness and measures pH - when eaten, the pH of a fruit or vegetable is closely related to the perceived tartness. In the paper listed below, Yahaya et al. developed pH calibrations for mangoes. Others have shown that other fruit properties, such as crispness or firmness in apples, are also quantifiable using near infrared spectroscopy.
