Cosmic rays and hyperspectral imaging are central features in two mining technology projects backed by the Advanced Manufacturing Growth Centre, with major implications for safety and access to strategically important materials, the centre says.
mDetect is a Swinburne University (Melbourne, Australia) spinout specialising in astrophysics research into muons, a type of subatomic particle that results from the Earth’s atmosphere being hit by cosmic rays. They are sometimes described as the heavy cousin of electrons, with their mass helping them pass deep into objects; much further, for example, than ground penetrating radar.
The company has commercialised telescopic devices and software in a system that uses muon behaviour to monitor and map tailings dams, providing real-time information on stability of the critical infrastructure in mining operations.
Assisted by A$248,191 ($161,354) in co-funding from AMGC’s Commercialisation Fund, mDetect has trialled its muography-based imaging system at OZ Minerals (now part of BHP) operations, and leveraged key partner Swinburne to assist with development, documentation, design for manufacture, production automation and other input ahead of scale manufacture. Back in 2021, the AMGC said OZ Minerals was expected to trial this at Carrapateena in South Australia.
Co-founder of mDetect, Dr Jerome Donovan, said: “Thanks to AMGC, we’ve gone from idea to impact, developing our product for commercial sales, securing key agreements and developing our design for scaling manufacturing – it has by far been our best government-funded program experience. With high-profile partnerships secured, mDetect is set to revolutionise global industries and enhance mining safety.
“Taking highly-technical IP – and which has heritage in dark matter research, no less – and delivering a market-ready product is never easy. But we are very nearly there thanks to the support from AMGC.”
The project is expected to lead to A$7.7 million in revenues in the fifth year after completion and has already resulted in new jobs at the growing company, according to the centre.
AMGC Managing Director, Dr Jens Goennemann, added: “An Australian manufacturer harnesses the power of space to protect lives on Earth. That’s Australian manufacturing at its best – globally relevant, collaborative and highly complex. mDetect is truly a leader in their field, poised to make a global impact.”
From using space particles to leveraging electromagnetic imaging, EQ Resources, the owner of the formerly dormant Mount Carbine tungsten mine in north Queensland, has devised a method to identify and extract tungsten from waste sources, following its discovery at the site in the year 1895.
AMGC supported EQ Resources through A$600,000 in co-investment to support a project to recover tungsten from a mine waste stockpile and low-grade deposits, incorporating hyperspectral imaging sensors on a wheel loader, artificial intelligence-assisted decision making, and X-ray sorting technology.
The project linked EQR with Mt Carbine Quarrying Operations, Plotlogic, TOMRA, Cronimet and the University of Queensland. It has helped deliver an additional A$3.6 million in revenues since completion of the project, according to the centre.
Kevin MacNeill, CEO of EQ Resources, said, “Early co-investment form AMGC allowed EQ Resources to accelerate the commercial development of our technology, furthermore it gave us the credibility to apply for follow-on programs and secure a A$6 million grant from the Critical Minerals Accelerator Initiative to move from pilot to operational scale.
“EQ Resources’ hyperspectral imaging technology demonstrates that there is still significant life in historical mines where waste piles are mountains of opportunity – in this case 130-year-old piles of tungsten containing waste.”
Goennemann said: “In taking a step back two centuries ago and looking at the resources we already have a hand, EQ Resources will be able to extract greater value from resources long-thought unusable both here in Australia and abroad.”
