Ore characterisation company Plotlogic and its proprietary OreSense® technology have been given a boost with the latest $28 million funding round, supported by US- and Australia-based venture capital climate and sustainability firms.

In the five years since its inception, Plotlogic has become a leader in ore characterisation. Its OreSense technology is helping customers, including BHP, Vale, South32 and Pilbara Minerals, increase output and reduce waste through the combination of a sensor stack and artificial intelligence (AI) to scan core samples, chips and terrain (including mine faces, stockpiles, heavy vehicle loads and plant feed) in real time. This stack generates highly accurate ore characterisation predictions enabling miners to increase extraction of critical minerals and metals, according to Plotlogic.

By enhancing grade control methods and identifying problematic ore and deleterious materials as well as optimising plant uptime, Plotlogic’s technology effectively reduces costs and energy usage for every tonne mined and processed, according to the company.

Galvanize Climate Solutions, the climate-focused global investment firm founded by billionaire Tom Steyer and Katie Hall, and SE Ventures, the investing firm backed by French energy and automation giant Schneider Electric, co-led the round. Existing investors Innovation Endeavors, DCVC, Bentley iTwin Ventures and GRIDS Capital also supported the raise, doubling down on their Series A investments. Main Sequence, the Australian deep-tech VC firm backed by the CSIRO and Australian government, also participated via its newly launched Main Sequence Three fund.

After achieving success with its single-application deployments of OreSense, Plotlogic says it has an ambitious growth agenda and is planning to use the Series B funding to broaden its platform across a greater number of touchpoints, bolster commercialisation and invest in additional research and development as the company looks to continue to expand into North America.

Founder and CEO, Dr Andrew Job, is confident the company will see escalation in adoption of OreSense, driven by mounting pressure on the mining industry to confront its most formidable challenge to date: providing the essential critical minerals required for a sustainable future while avoiding the repetition of past environmental harm.

“Recycling alone can only meet a fraction of the demand for essential commodities making continued mining essential,” Dr Job said. “And sustainability in mining can be achieved through the increased adoption of advanced technologies like ours. Discovering new deposits is a challenging task and the development of mines can take up to 17 years, pushing us well into the 2030s before we see any kind of transformation in the supply of minerals required for a net-zero future.”

He added: “Plotlogic is actively contributing to the pursuit of a clean energy future by enabling existing mines to extract every vestige of value right now in an environmentally sensitive way. We developed the OreSense technology with the firm belief that mining should be able to generate the resources society needs without harming the planet. The feedback from our customers is that we are delivering on that vision. They describe using our tech as a game changer – like swapping a hacksaw for a scalpel – enabling them to mine more selectively, efficiently and sustainably, benefiting both their projects and the planet.”

Thiess says it is taking another step to be at the forefront of sustainable mining with a technology trial involving Plotlogic’s OreSense solution at the Anthill copper project in Central Queensland, Australia.

With the promise of reduced environmental impact, improved safety and increased productivity the OreSense technology scans rock to distinguish high-grade resources from waste, Thiess explains. The technology provides real-time information, eliminating the need for a week or more waiting for testing results.

The technology is also expected to create environmental benefits through lower fuel usage and machinery consumables and a more optimised heap leaching process, according to Thiess.

Group Executive Growth & Strategy, Abdul Jarrah, said the trial aligned with Thiess’ commitment to use technology to drive sustainable improvements for our clients.

“Investing in technology such as OreSense further enhances our inhouse capability and allows us to offer our clients greater value across the safety, cost, productivity and environmental spectrum,” Jarrah said. “Importantly, our focus on innovation will support our clients to achieve their environmental goals as Thiess continues to establish itself as a leader in sustainable mining practices.”

Group Manager, Geology and Geotechnical, Donna Sheehy, said applications for the technology were far-reaching.

“The machine takes around three minutes to scan a wall or mine face area of 15 m by 50 m – if the trial proves successful there is potential to scan dig faces and stockpiles to determine grade,” she said.

“From machine learning we can use OreSense to give us real time assay – saving lengthy lab processing wait times.

“This allows us to increase the average grade of material fed to the heap leaching process which means we haul less waste, reducing our use of fuel and machinery consumables.”

The trial, set to begin at the Anthill copper project, owned by Austral Resources, on April 27, will run for around four weeks.

Austral says CSA Global completed an updated mining study in April 2021 on Anthill resulting in a JORC 2012 compliant ore reserve of 5.1 Mt grading 0.94% Cu containing 47,700 t of copper. This study outlined that ore will be mined from two pits over a 40-month period. Total recovered copper from the heap leach process will be 40,400 t over a 44-month period.

Plotlogic’s mission to deliver precision mining across the world has been given a boost with A$7.5 million ($5.5 million) of funding from international investors.

Plotlogic’s primary focus is on providing accurate real-time orebody knowledge to enable greater operational efficiency and resource utilisation. Its OreSense® technology has demonstrated its ability to improve health and safety, enhance overall mining operations and deliver tangible productivity gains, according to the company.

Andrew Job, former mining manager and company Founder, recently completed his PhD in artificial intelligence-based sensing at University of Queensland, and has said “Plotlogic’s technology is an exciting development in resource knowledge and forms an important part of our growth as we digitally transform our mining businesses”.

Plotlogic’s most recent international deployment of its OreSense system was to an Anglo American project in South Africa. This comes on top of deployments at BHP and South32’s operations.

The company says it continues to increase its global footprint with imminent deployments to South America, North America, Asia and Russia.

Precision mining with the help of technologies like OreSense have the potential to increase worldwide industry value by $370 billion/y, according to Plotlogic, while reducing carbon emissions and improving the sustainability of mines over their life cycle.

To support commercial expansion, Plotlogic’s team has grown substantially, with the team currently sitting at 30 people, up from only six a year ago. It also has plans to double in size before the end of this year.

The University of Queensland and research partners Plotlogic Pty Ltd have developed new automated mining technology that, they say, will facilitate automation of the mining process while improving operating efficiency.

The research has shown how artificial intelligence can use scans of the mine face to almost instantly identify valuable minerals and waste rock, allowing each stage of the mining process to be planned more effectively in advance, UQ said.

Professor Ross McAree, Head of School of Mechanical and Mining Engineering from UQ, said the new technology used visible and infrared light to automatically classify materials.

“Each mineral has its own characteristic response to different wavelengths of light, so by scanning the mine face with our system we can map out the minerals present in the rock and their concentration (ore grade) almost instantaneously,” Professor McAree said.

This real-time mapping allows the mining process to be planned out before digging even starts, according to the researchers.

“Beyond this immediate efficiency gain, the enhanced ability to recognise ore grade could also underpin future autonomous mine systems,” Professor McAree said. “Machines equipped with this imaging system would be able to recognise ore grade as they were excavating it. Linked to artificial intelligence, this could allow automated machinery to operate in the mine environment, removing workers from hazardous parts of the mining process.”

Real-time ore grade classification at the mine face could also enhance mine scheduling and improve resource recovery and minimise processing waste, the researchers claim.

The project was supported by the Minerals Research Institute of Western Australia (MRIWA), with MRIWA CEO, Nicole Roocke, saying investment into research like this helped position Australia’s minerals industry at the leading edge of technology development.

“This imaging approach could prove particularly valuable where rapid extraction and consistency of ore grades could provide a competitive advantage to those leading the way,” Roocke said.

The project, which was conducted in 2018-2019, had a total grant value of A$850,850 ($653,322). In addition to MRIWA, UQ and Plotlogic, CITIC Pacific Mining and AngloGold Ashanti were also involved, hosting trials at the Sino iron ore and Tropicana gold mines, in Western Australia, respectively.

It was based off the OreSense® prototype system, developed to meet the needs of the research project, as well as offering a commercial pathway for early industry adoption of the technology.

“The prototype delivers a system capable of acquiring, processing and classifying hyperspectral data in the field and in real time, mapped to terrain and geo-referenced for integration with mine maps,” the project partners said. “In order to be the most general and applicable to all minerals, the hyperspectral imaging capabilities cover the visible to short wave infrared spectrum (400-2,500 nm).

“The surveying capabilities of the system rotate in more than one axis to perform face scans and build a 3D data-cube from two individual line-scanning hyperspectral sensors. The system spatially and spectrally fuses the data cubes from the two sensors to provide a single data-cube for an entire scene. The system also performs on-board corrections and post-processing of the hyperspectral data to support real-time ore grade classification.”

The prototype used on site during the trials consisted of a sensor head with LiDAR and hyperspectral cameras, a pan-tilt unit and a GNSS receiver among other elements (see photo above).

Australia-based Plotlogic and its artificial intelligence-based ore-characterisation technology has won admirers from both venture capital funds and the world’s biggest miner by market capitalisation.

The company announced this week that four of the world’s top artificial intelligence (AI) focused venture capital funds – Baidu Ventures, DCVC, 8VC, and Grids Capital – had invested in an over-subscribed angel round of funding for the company.

On top of this, Plotlogic confirmed it had signed its first contract to embed OreSense, its new AI ore characterisation technology, into an iron ore mine site of BHP’s in the Pilbara of Western Australia. This technology uses hyperspectral analysis and AI to optimise ore recovery on mine sites.

Plotlogic’s vision is to enable autonomous mining operations using precise grade control with its new AI ore-characterisation technology, bringing technology that can “see and grade ore” to optimise operations and maximise yield, it said.

“Plotlogic uses AI, computer vision and spectral analysis in real time to optimise the recovery of ore from mine sites,” the company said. “Accurate ore intelligence enables precision mining that lowers operating costs, minimises energy consumption and reduces operational uncertainty.”

Precision mining with the help of technologies like OreSense have the potential to increase worldwide industry value by $370 billion/y, according to Plotlogic, while reducing carbon emissions and improving the sustainability of mines over their life cycle.

Founder and CEO, Andrew Job, said: “The mining industry is years behind other industries in utilising big data and AI: as a result, there is a lack of fast and accurate orebody knowledge that ultimately restricts yield. With our technology we can grade every tonne of ore accurately, before it even leaves the ground – driving efficiency, sustainability, and profitability. Plotlogic can optimise the mining process from pit-to-port with pinpoint precision.”

The team behind the technology, in addition to mining engineer Job, include Dr Richard Murphy, one of the world’s leading experts in hyperspectral geology, and Dr Michael Edgar, an experienced physicist and expert in optical sensors with experience spanning NASA and CalTech. Plotlogic has more than doubled its workforce since the start of the year, plans to double again before the end of the year, and once again next year, the company said.

Plotlogic said research collaborations with the University of Queensland’s Smart Machines Group and the Mineral Research Institute of Western Australia aided its quick establishment as a leader in real time high precision ore mapping and modelling.

Job said successful field trials with BHP’s iron ore and coal divisions, AngloGold Ashanti and Citic Pacific Mining over the past three years had provided valuable learnings that improved the technology and value proposition of OreSense across the iron ore, gold and coal sectors.

“Our technology has been purpose designed and built from the ground to best meet industry requirements,” he said.

On the BHP Iron Ore contract, Job said: “The opportunity to partner with the world’s biggest mining company is instrumental to our collaborative approach in the development and implementation of new technology for the mining industry.”
