AUSTRALIAN technology that provides new knowledge on ore bodies and associated alteration rapidly and cost-effectively could soon benefit the global mining industry through a commercialisation deal. CSIRO’s advanced mineral analysis and logging technology HyLogger has been licensed to Australian company Corescan, which operates a global network of hyperspectral mineralogy labs.

HyLogger uses the spectra of reflected light from mineral surfaces to interpret the mineralogy. It is far more reliable for systematic mineral identification than visual techniques used in most drilling programs. It also provides near real time analysis so that costs and delays associated with laboratory analysis are reduced.

CSIRO research director Dr Rob Hough said commercialising the technology with Corescan opened the way for the industry to take advantage of hyperspectral analysis of drill materials for exploration and mining, and reinforces Australia’s place as a global leader in the provision of exploration and mining technology.

“Through our partnership with the Australian state geological surveys, the National Virtual Core Library and AuScope, hyperspectral data is now routinely acquired at government core repositories and is generating new knowledge on mineral systems,” he said.

“Transferring the technology and ongoing development to Corescan will enable CSIRO to focus on the application and integration of hyperspectral information with other data sets to support mineral exploration through cover and for rapid resource characterisation in deposits.”

Corescan managing director Neil Goodey said the company planned to integrate HyLogger into its existing suite of advanced hyperspectral imaging equipment, giving it a broader range of solutions to accommodate different commodities and better meet customer requirements at different stages of the exploration and mining cycle.

“Corescan will also offer support services to the existing HyLogger community and will leverage its global reach to bring the technology to new international markets.

“Corescan will work closely with the Australian geological surveys and National Virtual Core Library to continue the great work that CSIRO has done in this area,” he said.
