IMDEX in deep dive study to show value of orebody knowledge

Leading global mining-tech company IMDEX is collaborating on what it says is a groundbreaking study backed by Canada’s preeminent sciences research body to determine the real value of orebody knowledge (OBK) in mineral exploration and mining.

IMDEX is partnering with the Mineral Deposit Research Unit (MDRU) and the Bradshaw Research Institute for Minerals and Mining (BRIMM) at the University of British Columbia, and Ideon Technologies, a leader in applying muon tomography for orebody imaging, in the million-dollar, two-year deep dive into the economics of OBK.

The MDRU is one of the largest integrated mineral deposit and exploration research groups in the world, dedicated to solving mineral exploration-related problems. The BRIMM creates multidisciplinary teams of leading researchers to work with industry to find solutions to the biggest challenges facing the mining industry and trains the next generation of multidisciplinary professionals.

The Natural Sciences and Engineering Research Council of Canada – the major federal agency responsible for funding natural sciences and engineering research in Canada – will part-fund the study through the NSERC Alliance program.

IMDEX Chief Geoscientist, Dave Lawie, said the research findings would contribute to knowledge on the economic benefits of enhanced OBK, promote adoption of new technologies, and help define future research and development directions in the mining industry.

“The mining industry has been slow to adopt innovative orebody knowledge approaches and data collection, despite the increasing improvement and sophistication of the technology,” Lawie said.

“One of the reasons for this reluctance is that mining companies, researchers and technology providers find it difficult to articulate the financial value of OBK; to explain in dollar terms the financial gain of being able to make better decisions earlier and reduce risk from greenfields exploration through to mining production.

“Clearly articulating the dollar value of OBK also assists in the adoption of technology where the cost is born in one part of an operation or organisation, but the dollar benefit is accrued in a different department or during a separate phase of development. It helps address the question, ‘Who will pay for what does not happen?’ where operational risk reduction is the key driver.

“Without quality OBK, companies are taking unnecessary mine development risks.

“For the mining industry to adopt this technology, it must have clear evidence of the financial impacts and risks of poor or no OBK and a way of assessing the most efficient methods of collecting, analysing and optimising it.”

IMDEX says it is leading the development of innovative orebody knowledge technology including through its IMDEX BLAST DOG™, a semi-autonomously deployed borehole sensing and physical measurement technology that provides near real-time orebody knowledge and physical information of the blast hole.

The company also has extensive experience in directional core drilling capabilities through its acquisition of Devico and its leading technology, which has benefits particularly in the search for deep mineral deposits.

Ideon’s technology generates images of orebodies deep beneath the Earth’s surface, up to 1 km below ground level, and has proven effective in detecting deep orebodies, which are challenging to locate using traditional methods, according to IMDEX.

“As exploration increasingly targets greater depths, deep OBK and efficient, environmentally sound methods of drill testing will become more relevant for making accurate early estimates of mineral reserves at speed,” Lawie said.

Senior researchers at UBC will drive the study along with a range of postdoctoral experts. The study will analyse mine projects completed over the past 23 years, integrating information from the Toronto Stock Exchange and the Australian Securities Exchange with the respective countries’ mine project reporting codes, the NI 43-101 and the JORC code, to assess the link between OBK – or lack of it – and mine project performance.

Other elements of the study will:

  • Quantify the write-down value attributable to orebody complications;
  • Quantify the link between OBK and mine project performance;
  • Assess the cost of obtaining OBK against the potential value lost in the project; and
  • Develop a risk assessment tool to allow companies to design work programs to optimise OBK and reduce project risk.

Lawie said previous UBC research by John Steen, Michael Samis and Andrew Gillis covering the period 2003 to 2016 revealed that geoscientific challenges were associated with financial losses by mine projects in at least 30% of cases, presenting the Value of Information case that has now expanded into the economic benefits of enhanced orebody knowledge.

This research will provide a starting point for the study using advanced data collection and interpretation to better understand the geological risks associated with mine development projects.

“To our knowledge, this integrated research approach has not been previously attempted,” Lawie said.

Mining and space sectors collaborate to solve the biggest challenges

A quiet revolution is underway in the mining sector as innovations and knowledge gleaned from space exploration help improve productivity, reduce emissions and create better outcomes for workers and communities, AROSE* Program Director, Michelle Keegan, explains.

The extreme demands of Space exploration and the drive for efficiency in the mining industry is creating new forms of cross-sector collaboration not seen before. The transfer of expertise and technology between these two sectors is also delivering solutions to some of humanity’s greatest challenges.

There are many commonalities between modern resource businesses and space exploration. Both require a focus on a smaller footprint, the delivery of zero-carbon emission operations and a reliance on substantial amounts of data to support decision making. They both operate in sensitive and challenging geographic environments and need to work in a way that reduces risks to their employees and the environments in which they operate.

The space industry provides a rich learning platform for the resources sector, for new approaches to increasingly difficult challenges. But the benefits of collaboration are not all one way. The space sector too is benefitting from the technological innovations and experience of miners here on Earth.

Technology developments in exploration precision, resource planning, advanced mineral detection sensors, in-situ extraction methodologies and advanced safety systems, present opportunities for insights and application in space.

Deep thinking around regulatory frameworks for responsible and sustainable space exploration and development will be enhanced through the experiences, both positive and negative, in terrestrial resource development.

Diversity of thinking

The opportunity to transfer technology and drive diversity of thinking from the space sector into mining will accelerate in the years ahead. Global demand for the critical minerals required to meet the world’s ambitious decarbonisation goals illustrates the need to leapfrog current approaches across the mining project lifecycle, from exploration through to production.

Rio Tinto CEO, Jakob Stausholm, recently described the global mining giant as a “technology company”.¹ In saying this he recognises Rio’s success in tackling the big challenges will rely on the miner’s ability to integrate new technologies and novel approaches to problem solving.

In a world where mining is becoming more complex, more difficult and more expensive, the ability to reduce costs (and emissions) and win the support of governments and local communities will rely on the ability to deploy technology to mine and process ore more efficiently and more safely, both for people and the environment.

Many post-carbon technologies, such as solar energy and battery storage systems, have been advanced through space exploration. Also, it is the systems engineering approach to project design, pioneered for space exploration, that increasingly is being adopted by terrestrial resources, technology and services companies.

Australia’s leading mining and oil and gas operators, as well as their major service companies, are aligning themselves with space-focussed businesses, researchers and industry organisations because they recognise the value of cross-sector collaboration. This new collaboration model is leading to greater technology and expertise transfer between space and resources. Miners also recognise the benefits of their best people being exposed to new knowledge and new ways of problem solving.

Trailblazer Lunar Rover project

The AROSE consortium was created for exactly this type of collaboration – to drive the growth of Australia’s space industry and bring together companies from resources and other industries, to leverage their collective capabilities and go after the toughest challenges in new ways. The Trailblazer Lunar Rover project is a first significant focal point for our space capable businesses and like-minded resources companies to pursue shared technology opportunities.

The AROSE Resources Advisory Board, established in 2022, creates an ongoing opportunity for the most innovative mining company leaders to provide input into the rover project, while taking learnings back to their businesses at the same time.

NASA understands well the benefits of this type of collaboration. Earlier this year AROSE participated in the first of a series of workshops with NASA and the United States Geological Service to look specifically at the areas of intersect between the resources and space sectors.

The mining industry is at a turning point in its decarbonisation journey. It has a once-in-a-generation opportunity to build new capabilities that will lay the foundations for long-term, sustainably driven growth. With an aggressive timeline to zero emissions, a great opportunity for the mining industry to solve this tough challenge is the successful building of relationships with uncommon partners like those in the space sector.

However, a broader partnership opportunity exists between mining and space. The domains we see as offering the best collaboration opportunities between space and mining include:

  • Automation and robotics;
  • Remote operations and control;
  • Geoscience;
  • Satellite communications and imagery;
  • Artificial intelligence;
  • Systems engineering;
  • Waste minimisation;
  • Digital design, including user experience and user interface; and
  • Data analytics.

It is evident space and mining projects are approached very differently. The design of a resources project is most typically achieved by bringing together the experiences of past projects, with a focus on budget and schedule. Operating concept or operating philosophy often takes second priority and does not drive the project design. As a result, an integrated systems design is never achieved. And while available technology enables some level of electrification, automation and digital decision making, the value that could be derived is never fully realised.

Andrew Dempster, Director at Australian Centre for Space Engineering Research at the University of NSW, says, “the high-level difference between the approaches of the two industries is that the mining (and oil and gas) decision points are all and always commercial, whereas the agency-driven space projects have more technical ‘system engineering’ decision criteria.”²

Dempster states “a fundamental observation about the difference between mining engineering and the space engineering disciplines (electrical, electronic, software, mechanical) is that the latter designs a product…while the former designs a business. It appears this is the fundamental disconnect”.

For many years the mining industry value chain has been unchallenged. Valuable resources are mined, processed then moved to a distribution point via rail or road and then shipped to a customer. However, there are several collaboration opportunities that could lead to mining companies rethinking value chain design, and these opportunities have the potential to alter the mining flowchart.

Perhaps the ideal approach we can use in mining is an integration of both approaches, and in this way adopt systems engineering thinking at the outset.

AI and data analytics

With an increasing need to build in automation, sensing and electrification, underpinned by digital platforms, the concept of operations needs an integrated approach more than ever. The growth in the application of AI and data analytics techniques to quickly interpret geological and physical properties of rock in mining has been exponential. As data streams become more complex and decision pressures more acute the demand for more sophisticated approaches to AI will only increase.

The space industry has had an even greater need to manage and interpret a plethora of complex data in real time to support mission critical decisions and there are obvious crossover opportunities to be explored in this arena.

With the hunt underway to locate resources on the moon or other planets to extend human life into outer space, the opportunity exists for mining technology companies to assist with rock knowledge acquisition and mineralogical interpretation of data required for successful space exploration.

Robotics and automation

The application of robotics and automation is expanding in the resources sector with the drive to remove people from harm and increase efficiency and precision in the mining process. Mining technology company IMDEX was motivated to partner with AROSE as a way of bringing space insights to the development of its BLAST DOG technology (pictured below), an automated logging system that collects detailed geoscience data from blast holes.

Major challenges IMDEX faced during the BLAST DOG development phase included: autonomous navigation over rough terrain; locating and positioning accurately over a blast hole; lowering and retrieving a sensitive, high-tech probe down the hole; and managing the transfer of high volumes of data through remote communication systems. IMDEX is refining its approach based on insights gleaned from companies involved in addressing these same challenges in space.

The recent affiliate agreement between AROSE and the Robotics Australia Group will increase this application across the industry.

Autonomous vehicles

In mining, the scale of operation has been linear until recently. If you wanted to increase mining output, you purchased more large equipment. Then came the introduction of fleet automation technologies, developed first by Caterpillar in 1996 and refined in partnership with Rio Tinto and other early adopters in the early 2000s.

Of the 1.5 million vehicles in use across heavy industry globally, only 1,200 vehicles are autonomous.³ Australia has the largest fleet of autonomous haul trucks in the world, with more than 700 in operation across 25 mines.4 Clearly the market potential is enormous.

These remotely operated technologies are challenging the need for ever larger truck sizes. The largest autonomous truck today might be the last of its kind as mining organisations consider what the ‘right size’ truck is for the future.

Smaller size trucks would allow miners to fully electrify their operations much sooner. In addition to the environmental benefits, there are operational and cost benefits that support this approach. The large autonomous trucks currently in use need enormous bi-directional roads. Reducing the size of mining vehicles can have a direct impact on strip ratios, and with a mine that can be up to 1 km deep, the roads that service the mine contribute significantly to the overall footprint.

While every mine design is different, there is a growing body of evidence that smaller autonomous vehicles can lower mine development costs (narrower benches, steeper pits, etc), speed operations and boost overall fleet utilisation.

The space industry has similar challenges with its autonomous vehicles. Where the mining industry is an expert at moving billions of tonnes of material by operating hundreds of autonomous vehicles all year round, the space industry today has only operated 11 semi-autonomous vehicles on a planetary body. This observation isn’t to diminish the significant achievement, as space exploration is extremely difficult, but to highlight the convergence of terrestrial and space objectives. For the space industry to perform in-situ resource utilisation activities anywhere off-earth, there is an opportunity to adopt learnings from the mining industry.

Likewise, the mining industry is moving towards smaller more specific/targeted mining practices and can learn from space industry experience in developing small-scale highly efficient and robust robotic solutions.

The space industry also provides a rich learning platform for the resources sector for new approaches to minimise and utilise the waste stream, with the ultimate goal of zero waste mining operations.

The companies which provide technology and services to the mining majors also realise they need to diversify their offering to include space. This ‘full stack’ approach may be a matter of business survival in a competitive future.

Remote operations specialist Fugro is a leader in this area. Fugro’s new SpAARC (Space Automation, Artificial Intelligence and Robotics Control) remote operations centre in Perth, Western Australia, has been specifically designed to share facilities between its established oil and gas and mining business and its fledgling space offering.

Fugro and Nova Systems are leading the AROSE consortium’s Trailblazer Lunar Rover design team. Woodside Energy and Rio Tinto are also supporting the AROSE Trailblazer effort by providing knowledge transfer of their terrestrial robotic and automation capabilities.

Woodside has also formed a collaboration with NASA on robotics and remote operations. NASA sees Woodside as a great test bed of robotics in harsh environments, as Woodside is doing similar tasks at its operations which NASA envisages doing on the Moon and Mars.5

The largest challenges facing the mining industry are the need to get to zero emissions, the need to get to zero harm and zero waste. There’s urgency in the call to solve all of these. It is now well-recognised that we need more collaboration not just within our sector, but across sectors. With the Moon to Mars program now underway, and the Trailblazer Lunar Rover program in place, this really is a tangible point in time where things are moving forward, a tangible point where people realise that this isn’t a dream, this is a reality.

As well as posting record underlying earnings for its financial year ending June 30, 2023, IMDEX made significant strides with deploying its newest technology, the company says.

This is the first set of financial results to include revenue from global directional drilling and sensor technology company, Devico, which IMEX acquired in February.

Revenue for the 2023 financial year was A$411.4 million (265.1 million), an increase of 20.3% on the previous year, which included four months of Devico revenue.

Underlying earnings, normalised for the Devico transaction costs as well as exceptional legal costs, was a record at A$122.6 million and delivered at a sustained margin of 30%, notable given the rising cost environment experienced more broadly in the mining industry, IMDEX noted.

IMDEX Chief Executive Officer, Paul House, said: “We are especially pleased at the record performance of the business and the sustained margins. This is a testament to the relentless effort by our teams around the world; the strength of our business model; and a reflection of our prior investment in our digital 1.0 platforms. This allowed us to ward off the rising cost environment while at the same time continue our investments in R&D and our IMDEX Mining Technology business unit.”

As well as the Devico acquisition, IMDEX took a 40% investment in drilling analytics software company Krux Analytics and increased its stake in geoscience image analysis company Datarock.

IMDEX continues to grow its suite of mining technologies including IMDEX BLAST DOG™ which remains in the commercial prototype phase with three units now on rent with trials in Western Australia, Queensland and South America.

Underground production hole survey technology IMDEX BOLT™ and blast hole stabiliser IMDEX BHS™, both commercial prototypes, have been installed in four sites with two trials underway and installed in 11 sites with five trials underway, respectively, it says.

During the financial year, the company achieved the commercial launch of its automated spectral mineralogy technology IMDEX aiSWYFT™, the advanced IMDEX OMNIX 38 & 42 GYRO™ and its core logging solution IMDEX LOGGERX™.

“IMDEX is well positioned to leverage the robust industry fundamentals and the unique competitive position its global presence, leading technologies and integrated solutions provide,” House said.

IMDEX joins Australian Automation and Robotics Precinct, plans for Dirt Lab

Automation, Explosives and blasting, Mining equipment, Mining safety, , , , , ,

IMDEX says it has become a major industry partner of the new Australian Automation and Robotics Precinct in Perth, Western Australia.

The partnership with the state government-owned precinct will allow IMDEX to accelerate testing and demonstration of technology including its BLAST DOG™ at a site close to its Balcatta headquarters

IMDEX BLAST DOG is a commodity-agnostic blasthole sensing and physical measurement technology that provides near real-time blasthole physicals and orebody knowledge, and a 3D view into the bench.

The 51 ha automation and robotics precinct 40 km north of the Perth Central Business District was purpose-built for testing, research and development, and training in autonomous, remote operations, and robotic systems and equipment.

Launched in October 2021, the Australian Automation and Robotics Precinct currently provides extensive test beds, freehold lots and an onsite office for industry use. It is being developed into a facility for innovation, with a state-of-the-art Common User Facility operation building, research and development facilities such as laboratories and design co-labs, and advanced test beds with multiple areas and roadways for physical testing.

IMDEX has signed on as an industry partner for an initial period of two years and will build and maintain a common user drill pad as a critical part of a 22 ha Dirt Lab, which will enable various commercial and collaborative opportunities as an innovation mine test and development site.

IMDEX Chief Executive Officer, Paul House (pictured on the right with IMDEX Chief Strategy Officer, Michelle Carey (centre) and Stuart Nahajski, DevelopmentWA General Manager Regional (left)), said having a purpose-built, robotics research and development site so close to the company’s headquarters was ideal.

“While we operate globally and have an unrivalled presence on all major mining operations, Western Australia is home to some of the world’s major mining companies so having the opportunity to develop and promote our technology locally is an additional benefit,” House said.

“BLAST DOG won’t be the only technology we will test at the site. We have plans for testing a range of IMDEX tools and technology developed by our research and development team.”

IMDEX has recently signed deals with two tier-one mining companies for further commercial testing of BLAST DOG.

The company achieved its first commercial contract with BLAST DOG in August 2022, at Iron Bridge in the Pilbara region of Western Australia, with the agreement providing for the staged use of up to three units together with associated products, software, data analysis, reporting and support.

Six commercial prototype trials were planned for the 2023 financial year under the first phase of BLAST DOG development.

BLAST DOG has been developed in collaboration with Universal Field Robots and IMDEX industry partners Teck Resources and Anglo American.

Gold Fields, UFR collaborating on automated underground truck pilot at Granny Smith

Gold Fields will soon begin an autonomous truck trial at its Granny Smith underground mine in Western Australia, leveraging the robotic smarts of Universal Field Robots (UFR) and an existing Epiroc Minetruck MT65 it has within its fleet.

In the company’s recently released annual results, Gold Fields stated it was developing its first underground automated truck, ready for trials at Granny Smith in the second half of this year.

Later, the company told IM that this project involved Brisbane-based UFR, with the machine in question having already received the custom paint job (see photo above).

The purpose of this trial is to validate autonomous truck haulage over shift change when the mine is evacuated for blasting, the company said in its annual results, with Rob Derries, Unit Manager: Innovation & Technology at Gold Fields Australia, confirming the truck will initially be tested and validated in a separate area underground at Granny Smith.

“Once validated, we will be operating the automated truck on the main decline over shift change when the mine is normally evacuated for blasting activities, enabling further material haulage in time where activities are normally halted,” he told IM.

The initial truck pilot is expected to continue for up to 12 months with plans to retrofit further trucks in the Granny Smith fleet to operate autonomously over shift change after validation of this initial pilot.

Gold Fields says it is investigating and partnering to develop a number of automation solutions to ensure the safety of its people while also enabling increased productivity.

Derries said: “This trial aligns with Gold Fields’ approach to adopting agnostic technology and automation solutions. In the future, this technology can be adopted on a number of different machine manufactures and types and will integrate with existing teleremote guidance LHDs and Mine Operating Systems.”

UFR, for its part, has been involved in the development of several automation projects within mining, including BLAST DOG™ blasthole sensing and physical measurement technology – in collaboration with IMDEX – and a robotic application for zero-entry work on underground production blastholes – a project it is working on with METS Ignited and several mining companies, including Gold Fields.

Granny Smith produced 288,000 oz of gold at an all-in cost of $1,171/oz in 2022. It is currently mining four lenses from the Wallaby orebody (Z70, Z80, Z90 and Z100), accessed from a single decline. Mining administration and maintenance is located at the Wallaby mine, while ore is processed at the Granny Smith carbon-in-pulp processing plant, 15 km east of the Wallaby underground mine, under campaign milling conditions.

Back in October 2022, Epiroc confirmed an order from Gold Fields for a fleet of 65-t payload Epiroc Minetruck MT65 underground haul trucks with automation features to be used at Granny Smith.

IMDEX delivers record H1 revenue amid ongoing M&A drive

IMDEX has announced record first-half revenue to end-2022 matched with targeted acquisition activity designed to, it says, further enhance its market-leading position.

The company reported strong growth in Africa, South America and the Asia Pacific, and increasing demand for critical minerals as it revealed record revenue of A$198.8 million ($137.7 million), an 18.4% increase on the same time last year.

During this period, the company announced plans to acquire Norway-based Devico AS in a A$334 million ($230 million) deal that, it said, would reinforce its market-leading position in mining technology and deliver increased market penetration. This deal, the company says, is expected to be completed by the end of February. The company also signed a binding heads of agreement to acquire a 40% in Krux analytics, which delivers drilling analytics software, and an increase in its Datarock holding to 40.9%, from 30 per cent, in the period.

Revenue from the Americas in the six-month period was up 14% on the same period last year to A$89.3 million; Africa and Europe up 22% (A$48.4 million); and Australia and Asia up 22% (A$61.1 million).

IMDEX Chief Executive Officer, Paul House, said the M&A activity was a highlight of the first half of the year and the results demonstrated the strength of the company’s core business.

“We are very pleased with the performance, particularly our ability to grow the business notwithstanding the current macro-related uncertainty in our operating environment and to deliver further margin expansion on a normalised basis,” he said. “The company is well positioned to leverage the robust industry fundamentals through the unique competitive position our global presence, leading technologies and integrated solutions provide.

“Combining the IMDEX and Devico businesses is expected to further strengthen this position.

“Directional drilling, a market where Devico is the leader, is one of the fastest growing segments of the mining-tech space, as companies continue to look for deposits at depth, explore complex ore bodies and respond to the growing needs of faster, cheaper more accurate drilling services.”

Normalised EBITDA for the first half of the year of A$62.8 million, which excludes the exceptional litigation costs not expected to recur during the remainder of the financial year, was up 22% on the same time last year, and up 11% on a constant currency basis.

House said revenue from sensors and software had increased as had activity linked to the search for critical minerals.

“The global commitment towards net-zero emissions and the resultant demand for critical metals or the continued extraction of reserves is outstripping their replacement,” he said.

“Critical minerals are growing at a faster rate and IMDEX is well place to benefit from the necessary supply demand rebalance.”

Industry growth was underpinned by strong demand from mid-to-major mining companies, which reported ongoing or expanded exploration budgets for 2023, and strong financing for junior and intermediate companies in December.

Other first-half highlights included:

  • Rock knowledge sensors on rent up 6% and IMDEX HUB-IQ™ connected revenue increased by 41%;
  • Released next generation IMDEX ioGAS™ V8 data analysis software;
  • Completed first generation IMDEX MINEPORTAL™ software to support BLAST DOG™ trials and contracts;
  • Commercial prototype IMDEX BLAST DOG™trials progressing as planned; and
  • Spectra analysed with aiSIRIS™ software up 4%.

IMDEX’s Lawie on BLAST DOG’s continual orebody knowledge evolution

Automation, Explosives and blasting, IoT, Mining equipment, Mining events, Mining services, Mining software, , , , , ,

In a presentation to the International Mining and Resources Conference (IMARC) in Sydney, Australia, today, entitled ‘Get a Dog’, IMDEX Chief Geoscientist and Chief Technologist – Mining, Dave Lawie, charted the five-year development journey of the company’s BLAST DOG™ technology that, the company says, provides unrivalled pre-blast orebody knowledge and a 3D view into the bench.

BLAST DOG is a commodity-agnostic blast hole sensing and physical measurement technology that will provide near real-time blast hole physicals and orebody knowledge, according to IMDEX. The value of the technology is in the power of integrated data, enabling experts to make informed decisions that affect each stage of the mining value chain.

“Ten years ago, orebody knowledge was quite an abstract notion,” Dr Lawie said. “When we first discussed it, people wanted more information. Five years ago, they were becoming more interested, and today it’s a theme in the industry.

“IMDEX has led that discussion and been at the forefront of the development of technologies that deliver better orebody knowledge. Reliable orebody knowledge is central to good mine planning. It provides the data that allows for informed decision making that delivers savings throughout the mining life cycle.”

The BLAST DOG sensor is on a track-mounted robotic platform with semi-autonomous hole positioning and alignment capability working over variable terrain and bench conditions, IMDEX explained.

IMDEX Chief Geoscientist and Chief Technologist – Mining, Dave Lawie

Directly and rapidly measuring the orebody via blast holes reveals what the ore reserve looks like in the ground, at a high resolution, and immediately prior to its extraction, providing mining companies with “insurance” data that protects people, heritage, equipment and neighbouring communities, according to the company.

The data has the potential to be used to develop programs to, the company says, improve safety; mine planning; blast design; fragmentation; reduce fume, flyrock, vibration, air-blast and dust; and improve material assignment post blast.

Dr Lawie said an IMARC presentation in 2015 discussing spatial factors among the activity drivers in mining confirmed to IMDEX that its identification and focus on orebody knowledge was correct. But at the time there was no “Internet of Geosensing” system able to deliver the right information.

“The reference to spatial factors is really the Internet of Geosensing; IoG is an orebody knowledge system, and that’s what BLAST DOG delivers,” he said.

The reduction or management of variation alone creates value, with the characterisation of waste as important as the identification of the target metals or minerals, according to IMDEX.

It creates the opportunity for better segregation of ore from waste during mining and, therefore, grade optimisation as well as maximisation of ore recovery and minimisation of dilution.

With the delivery vehicle coming from Universal Field Robots and the downhole sensors designed and refined by IMDEX, the addition of MinePortal 3D visualisation software has accelerated IMDEX BLAST DOG for mining production, IMDEX says.

The company achieved its first commercial contract with BLAST DOG in August this year, at Iron Bridge in the Pilbara region of Western Australia, with the agreement providing for the staged use of up to three units together with associated products, software, data analysis, reporting and support.

Six commercial prototype trials are planned for the 2023 financial year under the first phase of BLAST DOG development.

IMDEX concluded: “The BLAST DOG technology will continue to evolve, with new answer products, novel and democratised modelling and visual outputs being developed along with expansion to other commodities and geographies and eventually to underground applications.”

IMDEX reveals record quarterly results as new tech developments await deployment

IMDEX has revealed record September-quarter revenue amid a strong start to its financial year, with CEO Paul House noting revenue growth was up in all key regions with an increasing demand for real-time orebody knowledge and robust industry fundamentals.

IMDEX says its technologies enable resource companies and drilling contractors, to find, define, and mine orebodies – with precision, confidence and at speed.

Record unaudited first-quarter FY2023 revenue of A$105.9 million ($69.2 million) was up 22% on the same period last year, IMDEX said.

Sensors on hire were up 13% on a year ago and 9% on the previous quarter, meanwhile.

House, speaking at the company’s AGM today, said supply chain pressures also continued to ease during its first quarter of the financial year.

Revenue growth was up 17% year-on-year in the Americas, 29% in Africa and Europe, and 27% in Australia and Asia.

He said exploration budgets remained strong in Australia, with clients reporting longer order books of nine to 10 months rather than three to four months.

Major and mid-cap mining clients were reporting ongoing or expanded exploration budgets, and deeper orebodies were resulting in larger and more complex drilling programs, he added.

The drive to expand existing projects or find additional orebodies to sustain current production levels, continuing strong demand for metals across a broad range of sectors, and an increased demand for critical metals all contributed to a strong outlook.

“It is worth noting that during this current cycle, unlike any cycle previously, the industry has not made any major discoveries,” House said. “We believe that this supports both the continued need for exploration drilling and the importance of precision mining technologies that may improve the economics of smaller deposits or increase the mine life of existing operations.”

IMDEX CEO Paul House

House said that early in the first quarter of FY23 IMDEX signed its first significant commercial contract with a tier-one resource company in South Africa for its BORE HOLE STABILISER™ (BHS), part of its suite of drilling optimisation products.

BHS is a multifunctional product formulated specifically for air drilling applications, particularly drill & blast applications.

Trials are underway with underground commercial prototypes in Africa, Asia, and Australia, and further opportunities exist for surface applications, according to the company.

House also provided an update on development of BLAST DOG™, a multi-sensor probe designed to measure a wide range of geophysical properties of an orebody and map its material rock properties.

The data collected by BLAST DOG has the potential to be used by mining companies to develop programs that could improve mine planning, blast design, fragmentation and material movement tracking, post-blast.

IMDEX achieved the first commercial contract with BLAST DOG in August 2022, at Iron Bridge in the Pilbara. The agreement provides for the staged use of up to three BLAST DOG sensors, together with associated products, software, and support, over the initial term. This will result in an estimated contract value of A$13 million.

House added: “Our MINEPORTAL™ 3D visualisation software, acquired from DataCloud in September 2021, has been instrumental in demonstrating the value of BLAST DOG to customers,” House said.

He said the initial focus for development of BLAST DOG was copper and bulk metals within Australia and the Americas.

A rigorous assessment defined by global mines with the capacity for more than three drill rigs identified a serviceable addressable market beyond five years of approximately 400 sites, IMDEX says.

With IMDEX focussing on the top 25% of those that were more likely to support the introduction of technologies that are disruptive to existing mining workflows, the assessment had determined that the obtainable market over the same period was about 100 mine sites to support this first phase of growth for the BLAST DOG.

Six commercial prototype trials are planned for the 2023 financial year under the first phase of BLAST DOG development, according to the company.

“The next generation BLAST DOG will incorporate additional sensors, software, and data answer products, and we will expand its application to other commodities and geographies and eventually to underground applications,” House said.

Mining support technology, BLAST DOG, which was developed in Australia by IMDEX Limited, is set to be used at the Iron Bridge Operations in the Pilbara of Western Australia under a new three-year agreement.

Iron Bridge is an unincorporated joint venture between Fortescue Metals Group subsidiary FMG Iron Bridge and Formosa Steel IB, with the agreement being the first commercial application of IMDEX’s BLAST DOG.

The agreement provides for the staged utilisation of BLAST DOGs, which IMDEX estimates will generate revenue of A$13 million ($9.2 million) over the initial term.

The BLAST DOG is a commodity-agnostic blasthole sensing and physical measurement technology that is semi-autonomously deployed for logging material properties and blasthole characteristics at high spatial density across the bench and mine.

IMDEX Chief Executive Officer, Paul House, said this contract win was a defining moment for IMDEX.

“This is homegrown technology designed to provide meaningful, quantifiable benefits for the mining industry,” House said.

“We are not aware of any other technology that has the capacity to produce the same quantity and quality of pre-blast rock data and provide as large an impact on downstream processes.”

“The commercial success of BLAST DOG reflected in today’s announcement is a credit to IMDEX’s R&D team and their drive to make a difference in the mining industry.”

IMDEX Chief Geoscientist, Dave Lawie, said the company overcame many obstacles, including mine access issues caused by COVID-19, to deliver the BLAST DOG project in Australia and the Americas.

“Today’s announcement is exciting because we know what BLAST DOG can produce,” Lawie said.

“It is recognition for five years of intense effort spanning the USA, Queensland, Western Australia and Chile in conjunction with our METS Ignited project partners.

“In addition to the work for the Iron Bridge joint venture, we are involved in ongoing, pre-commercial trials across various operations in Australia, Canada and Chile.”

IMDEX’s BLAST DOG provides material physical property measurements prior to blasthole drilling to inform decisions regarding blasting, screening, blending and stockpiling, among others, before these materials are subject to processing. These properties form the inputs to a tactical approach to ore characterisation and processing, IMDEX says.

Possible benefits offered by IMDEX’s BLAST DOG include the ability of mining companies to develop programs which:

  • Optimise explosive selection and costs;
  • Improve fragmentation;
  • Improve material and grade control;
  • Reduce geotechnical risk;
  • Detect voids;
  • Define ore boundaries and prevent ore waste dilution; and
  • Reduce fume, flyrock, vibration, air-blast and dust.

The BLAST DOG contract capped off a year in which IMDEX delivered record revenue, record earnings and continued margin expansion.

It reported record revenue of $341.8 million, a 29.3% increase on the same time last year; alongside record EBITDA of A$104.9 million, an increase of 38.9% on last year; and net profit after tax of A$44.7 million, up 41% on last year.

IMDEX signs agreement with Tier 1 miner to fast-track development of MAGHAMMER

IMDEX has signed a joint development agreement with a Tier One mining company to fast-track development of the IMDEX MAGHAMMER™ for commercial use, according to Chief Executive Paul House (pictured).

The MAGHAMMER uses a hybrid drilling technique combining rotary diamond drilling with fluid driven percussive drilling to achieve higher penetration rates compared with conventional coring. The technology enables an entire drill hole to be completed with a coring rig where RC and diamond drilling is required, according to the company.

IMDEX only exercised its option to acquire Flexidrill and its patent-protected drilling productivity technologies, COREVIBE and MAGHAMMER, in December, but it had carried out test work on the MAGHAMMER technology far in advance of the transaction.

Speaking at the company’s AGM this week, House reported a new rental fleet record and month-on-month increases in revenue since May as IMDEX recovered from a COVID-19-related downturn earlier in the year.

With the strength of the gold price and other key commodities, and exploration activity surging, IMDEX’s tool rental fleet is 19% up on the same time last year and exceeds the previous record set in 2012, the company said.

House told the AGM that the recommencement of activity globally since May had continued in most regions, albeit at different speeds.

“We achieved revenue of A$61.4 million ($43.5 million) in Q1 2021 (September quarter of 2020), which was up 26% on Q4 2020 (June quarter of 2020),” House said. “This result is only slightly behind the previous corresponding year at A$67.6 million, or 4.9% on a constant currency basis.”

House said the company is seeing multi-commodity demand, with clients “well-funded” and focused on resuming sustained activity as soon as possible.

The pressures of COVID-19, which forced various governments to impose border and travel restrictions, created strong demand for IMDEX technologies linked to its cloud-based IMDEX HUBIQ™, the company said.

“We have made great progress both because of and in spite of COVID-19,” House said. “The global pandemic has increased demand for our connected technologies that support remote operations. Conversely, it has hindered client trials due to limited access to site for non-essential personnel.

“On balance, the momentum for disruptive technologies such as artificial intelligence, automation, and the industrial internet of things is gaining cadence.

“The outlook for mining tech is brighter than it has ever been.”

On top of the MAGHAMMER reveal, House said client trials of the award-winning IMDEX BLAST DOG™ had resumed.

IMDEX BLAST DOG is a semi-autonomously deployed system for logging material properties and blasthole characteristics at high spatial density across the bench and mine and is commodity agnostic.

Just last month, the technology, being developed in collaboration with Universal Field Robots and tested at Anglo American’s Dawson coal mine in Queensland, won the Greyhound Innovation (METS) Award at the 2020 Queensland Mining Awards.
