Australia’s AMGC accelerating muon detection, hyperspectral imaging mining work

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.”

OZ Minerals set to deploy mDetect’s ‘space particle’ tailings dam safety device

Australian start-up, mDetect, a spin-out company from Swinburne University of Technology, is using particles from space, known as muons, to, it says, help mining companies detect weaknesses in dams that secure highly toxic mining waste by-products, making them environmentally safer.

The hazardous waste early warning system, using muon technology, will revolutionise how mining companies monitor the stability of tailings dams, thanks to mDetect’s technology and a A$1.5 million ($1.09 million) co-investment grant from the Federal Government’s Advanced Manufacturing Growth Centre (AMGC) Commercialisation Fund and partners to fast track its commercial production, the university says.

Swinburne University of Technology’s Vice-Chancellor Professor, Pascale Quester, said research and education into space technologies and their terrestrial applications have extraordinary potential for positive economic and social impact.

“Swinburne is focused on ensuring that the vital research we do has significant positive impact,” Quester says. “The important work of mDetect, led by Swinburne’s Professor Alan Duffy, is emblematic of Swinburne’s cutting-edge research and our ability to market innovative ideas. This is paving the way for successful research commercialisation that provides real solutions for industries.”

OZ Minerals, as a key industry partner, has been integral to the development of the technology. The miner is expected to deploy the device at its tailings dam at the Carrapateena operation in South Australia.

Myles Johnston, General Manager of OZ Minerals Carrapateena Province, said: “OZ Minerals recognises our responsibility to meaningfully contribute to regional economic and social wellbeing as stronger communities create value for all stakeholders. By ethically and responsibly exploring for and mining copper, we contribute to a low carbon future and economic wellbeing, which helps us achieve our purpose and contribute to a better future.

“We congratulate mDetect on being awarded the AMGC grant, and the team at Carrapateena is excited to be collaborating with mDetect on the development of a fully supported, flexible 3D muon monitoring system.”

Professor Duffy said: “Muons are heavier versions of electrons that are made when cosmic rays slam into atoms in Earth’s atmosphere. We have patented new detectors, that, combined with powerful artificial intelligence techniques, take an X-ray style scan through solid rock revealing different density structures.”

This patented technology can provide intelligence on the internal structures and substances of buildings, infrastructure, and subterranean and aquatic features, opening up a range of commercial opportunities for the construction and mining industries, Swinburne University says.

“Simply put, muon technology can look through rock to create underground images and detect abnormalities which will provide the early warning signs needed to prevent potential structural failures.”

mDetect will work with local manufacturing company Elgee Industries and Swinburne’s Factory of the Future to produce the muon devices at scale. Connecting these devices and turning detections into underground images will be undertaken by Swinburne’s Astronomy Data and Computing Services software development team.
