Mineralogy data needs a push upstream, IMDEX’s Dr Lawie says

The resources sector creates problems for itself from the first drill hole to production by not acquiring the right data at the right time, according to IMDEX Chief Geoscientist, Dr Dave Lawie.

Speaking ahead of an IMDEX webinar to be delivered to coincide with this year’s Prospectors and Developers Association of Canada’s virtual conference, Dr Lawie said that with the technology now available there was no longer any excuses for failing to have enough data to make informed decisions at every point in the mining process.

“The industry wants to find, define and mine ‒ but that has to be done with speed and precision and that can only be achieved with reliable data at the right time, which is as early in the process as possible,” Dr Lawie said.

The IMDEX PDAC webinar ‒ What’s the real value of data? Pulling Decision Points Upstream ‒ will feature presentations from IMDEX Drilling Optimisation General Manager, Charles MacFadyen (The importance of drilling smarter metres); Automated Mineralogy Global Product Manager, Sasha Pontual (Digital mineralogy: why it is important for exploration and mining); and Geochemist and Senior Software Analyst, Putra Sadikin (IMDEX ioGAS: Analytics from the upstream to your desk).

Dr John Steen, the Director at Canada’s Bradshaw Research Initiative for Minerals and Mining, has said lack of orebody knowledge leaves companies vulnerable to unforeseen costs which, in some cases, could threaten a mine’s viability.

Substantial write-downs have been attributed to less-than-expected ore grades, access issues which required revised mine planning, and process recovery problems, all of which could be avoided with better orebody data, according to IMDEX.

Dr Lawie said IMDEX technology enabled exploration companies to “drill smart metres” by drilling fast, efficiently and getting early-stage data.

“Doing that, which can include digital mineralogy, in the early phases allows you to get your exploration done, to test more targets and to evaluate them while you are involved in the drilling program,” he said.

At the “define stage”, resources are often not brought into production because there are complications apart from grade often related to mineral recovery, deleterious components, different levels of hardness, which stem from a lack of orebody knowledge, Dr Lawie added.

“Mineralogy is a key component in the define phase ‒ it is in exploration, but it comes into its own in the define phase ‒ because it has so many downstream impacts on mining,” Dr Lawie said. “Push all that information upstream and you can move through the resource definition phase into mining with a lot more confidence because you won’t be trying to fix a problem with mineralogy at the mining phase.

“That sounds trivial, but it’s not, and it’s the causation of a lot of stranded resources. People have not acquired adequate data early enough; they get downstream and want to develop a mine plan so they conduct metallurgical tests which reveal problems that they could already have known about.”

Referring to the third presentation in the webinar, Dr Lawie said IMDEX ioGAS™, an exploratory data analysis software application developed specifically for the resources industry, allowed complex data interrogation to be made quickly and easily.

“To be able to make import decisions in these data-rich environments ‒ and the amount of data is only going to increase ‒ you need to make extracting information accessible,” he said. “IoGAS has been doing that for more than a decade.”

In-field mineral analysis key to unlocking further exploration dollars, IMDEX says

Exploration companies planning to cash in on the rush of capital into the mining sector risk losing out if they fail to take advantage of the latest tools to deliver real-time results from drilling programs, according to IMDEX.

Exploration activity is on the up ‒ spurred on by strong commodity prices supported by government stimulus, decarbonisation targets and demand across a broad range of sectors, the mining tech company says, referencing an Australia-focused exploration report from BDO.

In a sign of the surge in activity, there are reports of long delays at minerals testing laboratories in Western Australia, with miners and drillers waiting weeks for results, according to IMDEX.

IMDEX General Manager Product Development, Mark Gabbitus, said while verified laboratory samples were vital for mine planning, real-time in-field data also played an important part in decision making.

“The problem explorers face is that by the time they get the results back from a laboratory ‒ if it’s the only data they have ‒ it’s too late to make changes to the drilling program,” he said. “The holes have all been drilled and the rig is off site.

“IMDEX allows the geologist in the field to get quality data in near-real time that will allow them to make informed decisions. This data might not be the same as they use to build a model and make a billion-dollar investment to mine, but it is still material.

“With this real-time data, the geologist can make informed decisions about where to drill next, thereby maximising their limited exploration dollars.”

Additionally, using in-field solutions from IMDEX allows the geologist to decide which samples to send to the lab, or at least to prioritise which samples they need back quickly, helping them beat lab delays, according to Gabbitus.

“Capital will move to those who move quickly. Explorers who take weeks or months to get assay results risk being left behind,” he added. “With trusted data that shows promising results, you then have the opportunity to raise more cash or just change the way you go about drilling by drilling efficient holes.”

Gabbitus concluded: “Having indicative results from the field will help to put exploration and mining companies, alike, ahead of their competitors.”

IMDEX has a suite of downhole survey tools, core orientation and gamma logging technologies and in-field sampling and analysis products all linked to cloud-connected IMDEX HUB-IQ™ and data analysis software IMDEX ioGAS™.

IMDEX excited by structural changes in mining industry

IMDEX has heralded what it says is long-term structural change in the mining industry, as it reported a strong start to the first half of its financial year.

Delivering the company’s half-year results, IMDEX Chief Executive Officer, Paul House, revealed a robust balance sheet with a net cash position of A$47 million ($36 million) in the six months ending December 31, 2020, up 84% on the same time last year.

The company reported EBITDA of A$33.1 million, up 6% on the same time last year and 43% on the second half of 2020, on revenue of A$124.3 million, down 3% on the same time last year, but up 13% on the second half of 2020.
House said the balance sheet strength enabled the company to accelerate targeted research and development in line with demand, and leverage opportunities for growth through acquisitions.

He said IMDEX continued to navigate the impact of COVID-19 on its global operations and had responded to increasing demand for remote working technologies and software, upgrading IMDEXHUB™ and releasing new ioGAS 7.3™ geochemistry data analysis software.

The company has a record number of gyro-related technologies on rent and reached a milestone with a record number of instruments on rent for December and January, it said.

“While the opportunity ahead of us is exciting, we remain watchful and ready,” House said. “We are watchful of the current risks posed by COVID and ready to meet the increasing demand for mining technologies.

“This confluence of risk and opportunities is accelerating long-term structural change in the mining industry.”

House said activity increased in most regions, most notably Canada, the US and West Africa, boosted by strong industry fundamentals.

“Our global reach and unrivalled product offering mean we can grow in all market conditions,” House added.

IMDEX said the positive outlook for mining technology was being driven by investment in metals tied to decarbonisation such as aluminium, cobalt, copper, nickel and lithium; mining’s essential role in the global economic recovery; and the minerals industry embracing new technologies.

The overall industry drivers are being reflected in increased exploration budgets, the company added.

IMDEX also reported in these results that it had signed a joint development agreement with a Tier 1 mining company to accelerate one of its key “rock knowledge sensor” technologies for commercial use. It also has a joint development agreement to accelerate its drilling optimisation tool IMDEX MAGHAMMER™ for commercial use, with ground trials under that agreement having started.

Near-infrared tech can help solve sampling problems, IMDEX’s Dr Pontual says

Mineralogical data can be used across the entire mining value chain, from exploration to production, to build a detailed picture of a project, according to one of the world’s leading spectral mineralogy experts.

Dr Sasha Pontual, who developed aiSIRIS – a cloud-based artificial intelligence spectral interpretation software for portable spectrometer data – told an IMDEX Xploration Tech Symposium that mineralogy was critical for avoiding potentially costly surprises.

aiSIRIS (Artificial Intelligence Spectral InfraRed Interpretation System) is a proven technology that has processed more than two million spectra from more than 1,000 mining projects across the globe, according to Dr Pontual.

Dr Pontual joined IMDEX as Global Product Manager, Automated Mineralogy, when her company, AusSpec, was acquired by IMDEX in 2020.

“Historically, mineralogy sampling has not been adequate, with exploration companies relying more on the assay data and the geochemistry rather than actually using the mineral information,” Dr Pontual said. “We really need to know our rocks. This allows for decisions to be made in an informed way.

“Previously it has been based on low-density sampling. There are big volumes of samples spread through a deposit, but a lot of the work is associated with extrapolating the results from those low-density samples and basing some very critical decisions on small amounts of sample material.”

Dr Pontual says this low-density sampling is often not sufficient to get a detailed view of what is happening within a deposit.

“(This leads to) unwanted surprises during the mine life,” she said. “Some of them can be quite serious and lead to millions of dollars of loss and have serious adverse effects on the economics of a deposit.”

Dr Pontual said near-infrared technology could be used to determine mineral types and associations, mineral chemistry and crystallinity, in exploration to vector to potential mineralisation, in life of mine studies and mine planning, and at brownfields sites to extend known mineralisation.

Hand-held near-infrared tools offered ease of use, speed of collecting project-wide data sets and provided data that can be easily integrated with geochemical data.

“Hand-held spectrometers are still the fastest and most cost-effective way of collecting project-wide mineralogy,” Dr Pontual said. “The combination of an infrared spectral survey with a geochemical survey is very powerful because you’re then integrating that mineral information with your geochemical data.

“The complementary data sets allow for a more comprehensive understanding of the alteration system and the deposit.”

Hand-held spectrometers deliver substantial amounts of data for analysis, but “it’s no use getting volumes of data that are difficult to apply and to visualise in a geological context”, according to Dr Pontual.

“Industry requires accuracy and comprehensive information with detailed mineralogy, but with outputs that are easy to use,” she said.

Information needs to be standardised across projects and within companies, according to Dr Pontual.

Machine learning is the best way of getting accuracy and to train a system to be able to interpret the spectra in the same way as a spectral expert, she said.

Dr Pontual added: “This is how we developed the aiSIRIS system. This is a training set of real-world spectra that has all the variables built into it. We have close to two million real-world spectra and each one has been interpreted to an expert level.

“The system is very robust across a whole range of different geologies and different spectrometers and geological settings. You don’t need to do any preparatory work you can just go straight to your project, measure the spectra and analyse the spectra using the tool because you don’t need to create a project-specific spectral library for your project.”

aiSIRIS complements IMDEX’s existing in-field GeoAnalysis solution and integrates with IMDEX ioGAS™ software to provide further interpretation and analysis, the company said.

Robotics on its way to the exploration industry, QR’s Scott says

Automation, IoT, Mining events, Mining services, Mining software, , , , , , , ,

Mining has entered a robotics boom as developers take substantial strides in artificial intelligence (AI), use of drones, and data capture and analysis technology that will deliver safety improvements and better managed mines, Queensland Robotics Executive Chairman, Andrew Scott, says.

Speaking at the IMDEX Xploration Technology Symposium, he said that with the development of autonomous haulage and drilling technology, the mining industry had moved through a “trough of disillusionment” around robotics and was rapidly accelerating towards the “plateau of productivity”.

The two-day online conference brought together experts in mining innovation and exploration industries to discuss the latest in new technologies, tools and advanced analytics.

Scott said acceptance of new technologies had been aided by restrictions caused by the COVID-19 pandemic, with the development of some digital transformation projects planned for the next three to five years being executed in three months.

“COVID is a significant accelerator and robotics is no exception,” he said.

Capital was available to fund new and emerging projects and was another clear indicator of a robotics boom, which Scott said would undoubtedly mean more jobs not less.

“There’s a lot of work that’s underway right now to really bring to the forefront a lot of automation and robotics to deal with enhanced data capture and execution of exploration programs and also within the mining environment,” he said in an interview ahead of the symposium.

“In the mining environment, we’ve seen the proliferation of automation in the form of autonomous haulage and autonomous driving, but now we’re seeing all the other ancillary services that are requiring automation and robotic solutions to take people out of danger but also to enable a highly efficient and productive system.

“We’re starting to see some of those capabilities move across into exploration, including the ability to deploy smart sensors in the field robotically, the collection of samples, and the analytical processing of those samples.”

He told the symposium the increase in robotics was aided by a reduction in sensor and computational costs, and, with more tools and technology available, there was increased adoption and acceptance.

“Robots are helping with the dirty, dull and dangerous, and distance challenges,” he said. “Applying robotics can definitely remove people from harm’s way. It can also augment what they are able to achieve by being able to explore in environments where until now we’ve been limited.”

This included in Australia, with areas subject to extreme heat, the high altitudes of the Andes, and subsea exploration.

“Robotics is surfing the wave of AI,” he said. “There’s a huge amount of development and growth in this area. We’ve gone past the AI winter, as they call it, and the acceleration of tools, and the ease of use of those tools is becoming a critical enabler.

“My prediction is that we’re going to see more and more solutions where they’re highly engineered highly capable, robust, highly configurable and easy to use.”

Technology symposium set to uncover new mineral exploration techniques

An eclectic mix of topics including the use of bacterial DNA to determine mineral deposits, hyperspectral imaging of core samples and the rise of quantitative data analysis will be discussed at a two-day conference presented by IMDEX.

The IMDEX Xploration Tech Symposium, usually held in Vancouver, Canada, will this year be held online on January 12-13 featuring a range of international speakers. The conference brings together experts at the forefront of innovation in the mining and exploration industries and will examine the latest in new technologies, tools, and advanced analytics, the mining tech company says.

Among the speakers will be Chad Hewson, Manager, Geophysics and Innovation, at Teck Resources; Dr Ralf Tappert, Co-Founder of Hyperspectral Intelligence; and Dr Thomas Bissig, a consultant geoscientist with over 25 years of experience.

Dr Bissig and colleague Bianca Phillips, a PhD student, will discuss the use of unconventional techniques for geochemical exploration including bacterial DNA, gases and selectively sampling areas where seismic pumping may have occurred to determine potential sub-surface deposits.

“(Bacterial DNA) is a technique that really only has become a possibility with increased computing power and lower costs of genomic sequencing,” Dr Bissig said. “It’s a great example of interdisciplinary research. The biologists and the geologists can work together to find deposits.”

Dr Bissig added: “We’re still learning how bacteria specifically respond to the geochemistry. An example would be bacteria that eat sulphides for their energy source; if you have sulphides in the ground which typically are associated with elements of interest that we would like to mine, we can detect sulphides in DNA.”

He said early studies in Canada’s Northwest Territories had returned “compelling signals, much better than conventional grid sampling of soils”.

Seismic pumping is the assessment of elements brought to the surface in water during seismic events. This is where Dr Tappert’s focus on developing a robust, portable hyperspectral scanning tool for examining core samples comes in, with the result being the geoLOGr rock analyser (pictured). Hyperspectral Intelligence has sold geoLOGR units to mining companies in Canada and South Africa.

“Spectroscopy is relatively simple technology,” Dr Tappert said. “You just have to put it into the right instrument and make it usable for mines and exploration companies.”

He said companies were putting more effort into collecting basic data.

“The drill core logging is the basic information that the entire mine relies upon, especially with deposits where you’ll have marginal grades. It really depends on the accuracy of your basic geological model to make the mine feasible or not.

“Companies have realised this is important, and spectroscopy plays a key role. It’s essentially the only method that you can use to collect continuous compositional information from the drill core.”

Hewson’s presentation, meanwhile, will examine the move from qualitative to quantitative data interpretation using existing and emerging technologies.

“That could be from field-portable tools or drilling technology, whether it be in-hole or in the core shack, and then methods which will transform the data into quantitative geoscience products,” he said.

IMDEX, UFR win plaudits for Blast DOG deployment at Anglo’s Dawson mine

IMDEX’s Blast DOG™ technology is gaining recognition, with the drill and blast innovation winning a Queensland mining award last week.

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

A semi-autonomously deployed system for logging material properties and blast hole characteristics at high spatial density across the bench and mine, IMDEX Blast DOG™ is commodity agnostic. It is a semi-autonomous system that helps optimise blasting based on high-resolution three-dimensional material models built from sensor data. It is aimed at helping miners get predictable fragmentation and determine ore and waste boundaries, and control vibration, dust, fumes and heave, the company says.

“No other technology has the capacity to produce the same data and provide as large an impact on downstream processes including enhancing productivity,” IMDEX said.

The judges said UFR and IMDEX conquered the challenge of logging blast holes, while removing operators from harm’s way.

IMDEX Chief Executive Officer, Paul House, said: “To be the winner among such esteemed competition is a testament to the team and our collaboration partners, Universal Field Robots, Anglo American, Teck Resources Ltd and Orica, supported by METS Ignited.

“IMDEX has a passion to provide the mining industry with purpose-built solutions. IMDEX Blast DOG is no exception and we are investing heavily in solutions that provide significant benefit to our customers.”

The IMDEX Blast DOG solution moved from concept to prototype in just four months which provided the platform and justification to develop a commercial version, IMDEX says.

The innovation category was hotly debated, with judges looking at all five finalists as addressing the industry’s big issues. This included Emesent’s Hovermap drone payload for “mapping the inaccessible”, Polymathian – “Transforming Mining Value Chains with Industrial Mathematics”, Redeye Apps – “Optimising O&M Inspections – The Redeye Digital Twin” and Sedgman – “SMART Condition Monitoring”.

IMDEX SRU technology delivering water savings for drillers

Environmental, Mineral exploration, Mining equipment, Mining services, Sustainable mining, Water management, , , , ,

With the search for new mineral discoveries increasingly occurring at depth and undercover in remote locations, the pressure to find better ways to reduce water consumption during exploration drilling programs is vital as companies meet their environmental, social and governance obligations.

Global mining technology company IMDEX says it is meeting the challenges with solids removal units (SRUs) that can reduce water consumption by up to 80% during drilling. The savings mean less draw on water from sources including rivers, dams or underground aquifers, and a reduction in water transported to the drill sites.

Adoption of the technology has increased significantly in Europe to meet strict environmental guidelines, along with North America and some South American countries, IMDEX says. IMDEX SRUs Global Product Manager, Chris Havenga, said there had also been a dramatic increase in adoption in Africa in the past two years.

He said mining companies were increasingly directing drilling contractors to use SRUs because of the environmental benefits.

As an example, Havenga said a hole to be drilled to 500 m would require a ground sump with a capacity of 22,500 litres, but this would be reduced to 5,000 litres by using an SRU: a water saving of 77%.

Other benefits include a 75% reduction in drilling fluid consumption; water cartage and disposal costs reduced by up to 75%; and a saving of up to A$10,000 ($7,132) on digging and remediating sumps.

“With minerals being deeper and underground, deeper holes need to be drilled so holes of 1,000 m or more are no longer uncommon,” Havenga said. “Using the traditional sump method alone means increasing the number of sumps and the footprint of the drilling operation. The centrifuge in our SRUs means we speed up settling speeds and contractors can drill the same hole with less fluid and less solids retained in the fluids.”

Other benefits include improving relationships with land owners, gaining access to sensitive or remote areas, and reducing the risk to waterways and local wildlife.

IMDEX expands BLASTDOG drill and blast tech trials

IMDEX continued to advance testing of its BLASTDOG™ technology for drill and blast applications in the June quarter, with another two test sites near Brisbane, Queensland, established.

The company said it also accelerated progress with automated data and visualisation elements of the technology.

In an update almost a year ago, the company said it had carried out successful trials in Nevada, USA, and in Queensland, Australia, while it had additional trials planned in Chile and Australia in the first half of 2020.

BLASTDOG is a semi-autonomous system that helps optimise blasting based on high-resolution three-dimensional material models built from sensor data. It is aimed at helping miners get predictable fragmentation and determine ore and waste boundaries, and control vibration, dust, fumes and heave, the company says.

IMDEX is pursuing these developments as part of a METS Ignited project with Orica, Anglo American and Teck Resources.

Details of the latest BLASTDOG advancements came at the same time as the company released its 2020 financial year results.

These results showed off A$237.7 million ($171 million) of revenue for the year – with a record year-to-date revenue for the nine months ending March 31, 2020 – and EBITDA of $54.4 million.

The company said it had also seen an encouraging start to the 2020 financial year, with improving rental fleet numbers and continued strong industry fundamentals underpinning its growth.

Back in July, the company agreed to acquisition of AusSpec, an industry leader in automated mineralogy to the mining sector, in an A$8.5 million cash and shares deal.

IMDEX accelerates cloud-connected solutions on COVID-19-related demand

Communications in mining, IoT, Mining equipment, Mining services, Mining software, , , , , , , , , ,

IMDEX says interest in its cloud-connected technologies has spiked during the COVID-19 pandemic, the positive effect of which will flow through for the next 10 years.

There has been strong interest in IMDEX’s software technologies including IMDEX HUB-IQ™, IMDEX MUD AID™ and IMDEX IoGas™, it said, with registrations for webinars on digital workflow and training for data-related products having jumped.

Adoption of IMDEX EZ-TRAC™, a digital downhole survey instrument that uploads data to IMDEX HUB-IQ, has also doubled in the past 12 months, according to the company.

IMDEX Chief Executive, Paul House, said the new ways of working had accelerated the adoption of some of its products and training services by as much as 12 months.

“Things like our online training platform, IMDEX Academy; we had this training platform available to our employees but not our clients at the beginning of COVID-19,” House said. “It was an important project to us, but it wasn’t urgent. When COVID-19 came along, it went from being important to being urgent, and it accelerated both that product’s development and the time to market almost overnight.”

IMDEX is at least 12 months ahead on the rollout of its online training platform because of the adoption rate during the pandemic, it said.

Registrations for webinars and training related to digital products have increased significantly, with the most recent webinar on digital workflow attracting about 500 registrations, compared with previous webinars with no more than 100, IMDEX said.

House says IMDEX can move the knowledge base of the industry quickly.

“It’s a conversation in the marketplace, it validates our leadership position and our domain knowledge ownership, it’s transformational for us and that will pay off for us for the next 10 years,” he said.

“Where would usually have to ask customers to consider a change in behaviour, to take a leap of faith, all of those things are being pulled into the market rather than pushed. The processes that are being disrupted have a solution, which is some of our IMDEX solutions.”

House concluded: “We always say once you have started working with our solutions, you won’t go back. So, the adoption rate is faster, and the conversation rate is locked in.”
