Overview of aiSIRIS

aiSIRIS makes it easy for anyone who uses portable spectrometers in their operations to have cost-effective, complete, fast, quantitative, and standardised interpretations of spectral data that integrates with existing workflows.

As an SOP, aiSIRIS offers standardised outputs of complete mineralogy and analytics that can be trusted for detailed alteration and geomet modelling across all sites. 

aiSIRIS is a cloud-based spectral interpretation AI solution for portable spectrometer data. aiSIRIS has been developed by AusSpec from 25+ years experience applying the technology in mining and exploration applications. 


Scalable pricing on a per spectrum basis.

“The low price per sample provides outstanding added value.” - Sean McKinley, Eldorado Gold


Receive 8 minerals rather than one or two.

“This is revolutionary as far as i am concerned. We can now get beyond mineral 1&2 and start talking about the implication of the complete results.” - Chief Geologist, Global mining and resources company 


The system can deliver 1000's of results per day.

"Amazingly good to be able to view our results so fast." -Regional Manager, Global mining and resources company 


Quantitative measures of mineral spectral abundance.

“The quantitative outputs allow rapid implicit modelling of the distribution of individual minerals.” - Tim Baker, Eldorado Gold


Allows for repeatability and predictability of process between sites and over time.

"We can trust the aiSIRIS results to go directly into our database.” - Sue Drieberg, Principal Geochemist, Rio Tinto


Comprehensive mineral information and quantitative outputs can easily be integrated with other datasets and allow rapid implicit modelling of the distribution of individual minerals.

"The combination of 4 acid digest ICP-MS data from ALS with the aiSIRIS spectral analysis is fantastic. These are very complementary data sets; each shows things that the other cannot measure.” - Scott Halley, Mineral Mapping

“aiSIRIS allowed us to quantitatively assess our spectral data. [With implicit modelling], the relationships between these domains and critical features, such as gold grades, recoveries and geotech characteristics, can easily be examined resulting in much more robust and detailed models.”

“aiSIRIS allows you to maintain a knowldge base across a company.”


Chief Geochemist, large uranium minex company 

"We have better things to do than look at spectra, aiSIRIS is more accurate and more rigorous.”

Case Studies

Case Study 1

Alteration Modelling in an Operating Mine with historically
unreliable alteration model.

  1. CLIENT SITUATION - An operating mine had an unreliable alteration model and spectral interpretation results that conflicted with the XRD data. 
  2. aiSIRIS RESPONSE - The company reprocessed their historical IR data and rebuilt their alteration model. They now use aiSIRIS as part of their ongoing operations.
  3. CLIENT OUTCOME - Improved understanding of the alteration system has allowed better modelling and planning for ongoing and future mine production.

“The quantitative nature of the new aiSIRIS spectral data outputs combined with the powerful, rapid 3D modelling capabilities of implicit modelling software have given us the necessary tools to advance the geological, geotechnical and geometallurgical models at Kişladağ and to improve the efficiency of mining and processing in the future.”

Tim Baker, Chief Geoscientist, Eldorado Gold

Case Study 2

Alteration Modeling for Mine Planning in Complex Geology with limited in-house Interpretation Skills.

  1. CLIENT SITUATION - A new discovery with complex geology required detailed alteration modeling for evaluation and planning. In-house interpretation had proved inadequate to extract all relevant mineral information from the spectral data. 
  2. aiSIRIS RESPONSE - Used aiSIRIS to interpret over 40,000 historical spectra from a collection of drill holes and pulp samples.
  3. CLIENT OUTCOME - Gained a deeper understanding of the alteration system and its extent.  

'aiSIRIS has given us a leap in understanding, in a complex data set.'

Regional Manager Project Generation, Global mining and resources company

Case Study 3

Global standardisation of spectral geology analysis
and reporting across a company.

  1. CLIENT SITUATION - Large inconsistencies and inaccuracies in the reporting of spectral mineralogy results across the company meant that it was not possible to get the information into the company database to integrate with other data sets. 
  2. aiSIRIS RESPONSE - Adopted aiSIRIS globally in all sites using spectrometers, for standard reporting and analysis workflow.
  3. CLIENT OUTCOME - Standardised workflow and outputs allows the aiSIRIS results to be directly incorporated into the company database, making for easy integration with other geological data sets and easy storage of valuable mineral information.  

“aiSIRIS provides consistency in spectral processing and QA, interpretation and reporting so we can trust the aiSIRIS results to go directly into our database.”

Sue Drieberg, Principal Geochemist, Rio Tinto


Case Study 4

Alteration Modeling in Large, Complex Porphyry System.

  1. CLIENT SITUATION - Needed to create an alteration model for a large, complex porphyry system.                            
  2. aiSIRIS RESPONSE - Adopted aiSIRIS as a standard interpretation solution for detailed mineralogy and integrated it with their assay data set.
  3. CLIENT OUTCOME - Integration with the multielement geochemistry data set allowed them to gain an in depth understanding of the alteration system.

'I was pretty impressed with the results! It is great merging the data with the chemistry because that also gives a proxy for the feldspar compositions and abundance.'

Scott Halley, Mineral Mapping

the aiSIRIS story

"For 25 years I have been fortunate to have played a part in the evolution of spectral technology advancement starting from the early PIMA spectrometers, to developing TSG, the GMEX spectral manuals, GESSL and commercialising the hylogging systems. During this time I have seen the industry take on board these technologies and seen improvements in the way we understand mineralogy and its contribution to alteration.
That said, I have felt that many of the gathered spectral datasets have been massively underutilised and industry has not truly benefited from the kind of information that spectral data offers. Knowing this I was inspired to develop the aiSIRIS processing system to transform an undervalued dataset into a truly useful and dynamic space, from which accurate and standardised data can contribute to better and more informed decisions. "

Our Timeline


PIMA protoytype

AusSpec field tested prototype field spectrometer
developed by Integrated Spectronics. 


Commercialisation of PIMA

 A long road trip around Australia.


Development of TSG software

An AusSpec consortium funded project to develop a commercial spectral processing package, AusSpec designed an interface to front an early piece of spectral processing software (called XSpectra), which became “TSG”. Since then AusSpec has worked closely with CSIRO developing and beta testing variants of TSG (Viewer, Lite and Core) and has provided CSIRO with a business platform to market and sell TSG worldwide.
