The HyLogger 4 spectral scanner has been installed at the Londonderry Core Library in New South Wales, marking the first time the cutting-edge critical minerals technology has been adopted in Australia.
HyLogger was designed by CSIRO and is a rapid spectroscopic logging and imaging system that uses continuous visible and ultraviolet spectroscopy and digital imaging to examine cores, samples and cuttings without destroying them in the process.
The fourth generation of the automated technology has introduced the mid-infrared range, providing a continuous spectrum from 380 to 15,500 nanometres. The mid-infrared range can be used to classify organic materials and identify minerals not recognised in the other spectral regions.
HyLogger 4 also delivers increases in core tray imagery resolution of up to 25 micrometres, permitting analysis of textural information and detailed mineral relationships.
The system’s ability to capture high-resolution digital images and detailed mineralogical information at a millimetre scale will allow the mining industry to make substantial advancements in mineral exploration and research.
“The state-of-the-art rapid spectroscopic machine uses a logging and imaging system that employs continuous visible and infrared spectroscopy with digital imaging to analyse drill cores, samples, and cuttings without causing damage,” Geoscience chief geoscientist and head of the geological survey Phillip Blevin said.
“This innovative machine will enhance our understanding of mineralogy, improving efficiency in geological studies and boosting the future of critical minerals in NSW.”
To aid Londonderry upgrading to HyLogger 4 from HyLogger 3, the NSW Government invested $450,000 as part of its commitment to unlocking critical minerals needed for the global energy transition.
“Survey geologists have been collecting spectral signatures of samples from the state’s mineral collection known to be associated with critical mineral and high-tech minerals deposits to train the HyLogger 4 to identify similar minerals in drill core and rock samples that otherwise would not be visible to the naked eye,” Blevin said.
“By embracing technologies like the HyLogger 4, we are not just investing in our resources sector, but also ensuring that we do so responsibly and sustainably, which aligns with our commitment to protect our environment while harnessing the benefits of our rich mineral resources.”
