AUSTRALIAN METS that they can have persistent autonomy and operate for days .”
In this setup , track and trace monitoring by GlassTerra will create feedback to a machine learning / machine translation engine to optimise activities to create persistent autonomy to extend operation for days and even weeks , according to Sterling . The company hopes to be carrying out proof of concept work for this in the next year .
The resources to reconcile
Another example of the type of commercialised research projects METS Ignited ’ s Beer flagged comes from South Australia-based Chrysos Corp and PhotonAssay technology .
Initiated by researchers at the world-renowned CSIRO , Australia ’ s national science agency , back in 1991 , PhotonAssay has gone on to become a commercial success at home and abroad .
The technology delivers faster , more accurate gold analysis , being a quantitative , chemistryfree replacement for fire assay on site and in the laboratory , Chrysos says . It uses high-power X- rays to activate and measure gold atoms in mineral samples . Compared with conventional X- ray Fluorescence , the much higher energies used in PhotonAssay allow true bulk measurements of large samples independent of their physical or chemical form , according to the company .
With more than 800,000 commercial samples now processed with PhotonAssay , Dirk Treasure ,
CEO of Chrysos , reflected on the importance of the company ’ s CSIRO link .
“ The partners we have brought into the company have really got us to where we are , one of which is CSIRO ,” he told IM , referencing Ausdrill ( now Perenti ), RFC Ambrian and Chrysos ’ Chinese manufacturer as the other partners . “ We benefit from 15 years of development of that technology prior to picking it up ourselves in 2016 . In the early days when people did not really know who we were , it was very useful to explain this is a legitimate CSIRO product that has all the right people involved .”
So important has this link been , Chrysos brought the PhotonAssay inventor and lead CSIRO scientist onto its management team when it acquired the technology five years ago . And , even to this day , Chrysos remains part of the science agency ’ s nurturing ecosystem .
“ CSIRO are excellent at finding the right people to work with , as has been shown with PhotonAssay and some of their other operations ,” Treasure said . “ On top of those connections , we also benefit from operating on a

CSIRO campus and having huge amounts of support whenever we need it – we have access to their labs , their staff and their ICT system , etc .”
With this backing , Chrysos has managed to move from lab trials to commercial deployments of PhotonAssay across the globe .
Of late , this has seen the company install a PhotonAssay unit for Kirkland Lake Gold ’ s Fosterville mine , in Victoria , plus win a PhotonAssay contract to become part of the
