Giga Metals Corp has announced the results of a prefeasibility study (PFS) on its majority-owned Turnagain nickel-cobalt project in British Columbia, Canada, that could use both trolley assist technology, as well as an autonomous haulage system.

Turnagain is owned by Hard Creek Nickel Corp, a joint venture owned by Giga Metals (85%) and Mitsubishi Corporation (15%).

The PFS outlined annual production averaging 37,288 t/y of nickel and cobalt in concentrate over the nominal full operating rate period (years 3 to 28) based on a 30-year project life with a strip ratio of 0.4 tonnes waste per tonne of ore

It also highlighted Scope 1+2 carbon intensity of less than 1.8 tonnes of CO2 per tonne of Ni in concentrate.

The PFS builds on significant metallurgical and engineering studies and confirms the ability of Turnagain to produce high-quality nickel concentrate, Giga Metals said. It has been led and prepared by Tetra Tech Canada Inc along with input from industry expert consultants.

Giga Metals said: “The PFS demonstrates a long-life, large-scale project that will deliver high-grade nickel sulphide concentrate with no significant deleterious impurities, into commercially proven processes such as pyrometallurgical smelters or hydrometallurgical refining using pressure oxidation facilities.”

The project, Giga Metals says, has notable responsible mining characteristics beyond the low-carbon production including the following:

  • Sequestration of CO2 through naturally occurring mineral carbonation, transforming the tailings management facility into a permanent carbon mineralisation facility;
  • Safe and efficient tailings storage using centreline and downstream tailings dams in sub-aerial valley impoundment;
  • A near-neutral water balance; and
  • Being located in a well-regulated and experienced mining jurisdiction that has adopted First Nations’ rights to achieve informed consent during the permitting process.

The capital cost associated with the project has been slated as $1.89 billion with a post-tax IRR and NPV of 11.4% and $574 million at a long-term nickel price of $9.75/lb, with 78% payability for nickel in concentrate.

The Turnagain open-pit deposit will be developed using large haul trucks (227 t capacity), loaders, and electric shovels to minimise unit costs, the company says.

“Proven trolley-assist technology and autonomous haulage technology have been selected for reduced total costs and environmental footprint,” it added.

The mining operations are scheduled for a 28-year mine production period to support a 30-year processing plant operating period, and include the Horsetrail, Northwest and Duffy mineralized areas (collectively, the Horsetrail zone). The orebody is mined as a single main pit with five pushback phases through the life of mine and a small satellite pit for the Duffy zone. Overall main pit dimensions are approximately 2 km x 1.5 km.

The mine plan will deliver an annual processing plant feed rate of 32.85 Mt/y (90,000 t/d) after the installation of the second processing train in Year 1. The resource will be selectively mined with low-grade materials placed on a low-grade ore stockpile for later recovery. The maximum low-grade ore stockpile size has been reduced by 82% from the 2020 preliminary economic assessment to 34 Mt, which represents an approach that accounts for regulatory expectations to minimise stockpiling as well as practical mining operations.

Processing of Turnagain ore is conventional, Giga Metals says, with the processing plant consisting of the following:

  • A primary crusher followed by two trains of closed-circuit secondary crushing and HPGRs;
  • Two grinding trains, each comprising two closed-circuit ball mills in series;
  • Two rougher flotation trains, each comprising two banks of rougher cells;
  • Two trains of three-stage cleaning circuits plus cleaner-scavenger flotation;
  • Concentrate thickening and two trains of pressure filtration; and
  • Associated utility and reagent systems.

The processing plant will be installed in slightly offset stages to maximise the efficiency of construction and commissioning. The second processing train will be installed and commissioned parallel to the first train in the first full year of operations. The primary crusher is located adjacent to the mine to reduce haul distances and the crushed ore is conveyed to the processing facility located across the Turnagain River and above the tailings management facility. This allows for energy-efficient conveying of crushed ore and eliminates high-pressure pumping of slurries. All equipment selected is commercial-scale industry-standard, including mechanical flotation cells, the company added.

Turnagain concentrate is expected to be high grade, averaging 18% Ni and 1.1% Co, with low levels of deleterious impurities. Iron, sulphur and magnesium are expected to be within typical ranges for smelter operation, with nominally 30-35% Fe, 20-25% S and 4-6% Mg.

Automated processes needed to optimise people management, Advanced says

Automation, Mining services, , , ,

Mining companies are being urged to automate their time and attendance procedures if they want to reduce timesheet inaccuracies and labour costs and gain insightful workforce data.

Advanced’s Damien Durston said miners were increasingly doing away with paper-based time and attendance solutions in favour of automated ones, with the company’s Time & Attendance software one of the options.

“One of the greatest and most complex costs in the mining industry is labour,” Durston said. “With more than 100 award rates in Australia, it’s a huge gamble for employers to pay their employees correctly when time and attendance procedures are still done manually.

“I think many companies who are still doing manual inputting would be astounded at the amount of unauthorised overtime they have leaking out the back door.”

Durston warns employers to do their homework when choosing the right automated time and attendance system, which give supervisors and managers access to real-time data to manage staff, backfill staff in an emergency, optimise overtime and streamline administration work, all the while saving significant money.

“It massively helps though if you have the right award interpretation built into the backend of the software so you can pay your employees correctly and within the law,” he says. “There have been examples of companies accidently underpaying or overpaying employees due to award rates incorrectly being applied for public holidays, and this all comes down to implementation issues.

“Ensure your provider understands award rates for Australia and how to apply them. Implementation should be done on shore, working closely with Fair Work Australia, the Australian Tax Office, and Fair Work Ombudsman.”

SGS, a leading testing, inspection and certification company, has unveiled Automated pXRF (Portable X-ray Fluorescence) technology to, it says, further support its clients in unlocking future-focused solutions.

Designed and developed by SGS and Evident, this solution marks a significant leap forward from the conventional, manual XRF process or the in-field pXRF service, SGS claims.

The current method of manual XRF analysis requires dedicated operators to load and unload each powder rock sample individually. SGS’s Automated pXRF technology introduces a mechanised solution that streamlines the entire process. This innovation provides a more stable and reliable environment and allows operators to load up to 20 sample trays, improving efficiency of the analysis, according to the company. The new design and capability reduces turnaround time and analysis costs, expediting the delivery of critical insights for geological modelling.

The Automated pXRF system also increases the quality and consistency of sample measurement with high accuracy and repeatability, while reducing human error associated with manual loading and operator involvement during analysis. This advancement improves data reliability and enhances decision making for businesses reliant on precise analysis across critical mineral analysis and gold and lithium pathfinders.

Juan Smith, General Manager of Natural Resources Australia, and Regional Geochem Manager for Southeast Asia Pacific, said: “Our clients are constantly looking at which technologies can deliver better and faster results, and automated pXRF will be a game changer. This innovation aligns seamlessly with our dedication to providing industry-leading solutions that redefine standards. The Automated pXRF system reflects SGS’s unwavering commitment to efficiency, accuracy and safety, ultimately benefiting our clients and the environment.”

SGS said the unveiling of SGS’s Automated pXRF technology is poised to “reshape” critical mineral and pathfinder analysis, setting new benchmarks for efficiency, quality and safety.

SGS in Australia is already providing the service to several Tier One mining companies, ensuring bespoke solutions for each client, it says.

The company concluded: “With its capability to process a high volume of samples while reducing costs and enhancing data reliability, SGS continues to lead the way in technological advancements within the TIC industry.”

Volvo and Boliden partner on autonomous transport and load solutions

Automation, Base metals, Mining equipment, Mining services, , , , , ,

Volvo Autonomous Solutions (VAS) and Boliden have entered into a long-term collaboration that will see the pair take on various projects, the first of which will be the implementation of an autonomous transport and load solution for a dam project in Garpenberg, Sweden.

The MoU also includes an agreement by VAS to deliver an autonomous transport solution that will move rock fill from an on-site quarry.

As a part of the implementation, VAS will deliver a complete autonomous transport solution that includes vehicles, hardware, software, control room, repair and maintenance, and training. The solution will be based on the OEM’s in-house developed virtual driver and the Volvo Trucks’ premium truck range.

To prepare the site for the implementation of autonomous trucks, Boliden will adapt its operations and build the necessary infrastructure.

Nils Jaeger, President of Volvo Autonomous Solutions, said: “Whether it is removing people from hazardous environments, 24/7 operations unencumbered by working hours or reducing emissions through better utilisation of resources and assets – autonomy offers several benefits that can help the mining and quarrying industries address its most pressing challenges. We are excited to partner with Boliden and support their journey towards a future where autonomous vehicles and humans work side by side to make Boliden’s operations safer, more efficient and sustainable.”

Mikael Staffas, President and CEO of Boliden, said: “Autonomous solutions benefit both safety and productivity. The partnership with VAS is therefore of great strategic importance and we are of course delighted with the project in Garpenberg already underway. Demand for base metals will increase going forward and sustainable as well as competitive solutions will be key in the value creation of mining.”

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’s new SpAARC 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.

Boliden Garpenberg receives Sandvik’s first automation-ready battery-electric Toro LH518iB LHD

Automation, Base metals, Mine operation news, Mining equipment, Mining safety, Mining services, , , , , , , , , , , ,

Boliden’s Garpenberg zinc operation in Sweden has taken delivery of Sandvik’s first Toro™ LH518iB with AutoMine® as part of a 12-month collaborative trial of the new automation-ready 18-tonne battery-electric loader.

Considered one of the most modern mining operations, Garpenberg is the world’s most productive underground zinc mine and Sweden’s oldest mining area still in operation. The mine is now set to become the first in Europe to trial a Sandvik battery-electric loader, the OEM says.

The Toro LH518iB will support Boliden’s efforts to improve sustainability by reducing greenhouse gas emissions underground. The company’s climate targets include a 40% reduction of absolute CO2 emissions in Scope 1 and 2 and 30% reduction of Scope 3 emissions by 2030.

Jenny Gotthardsson, Garpenberg’s General Manager, said: “We are proud to be recipients of the very first Toro LH518iB with AutoMine. The unit has already undergone extensive factory testing in Finland and we look forward to really putting it through its paces now in our operation. We’re on a journey to reduce fossil fuel usage and CO2 emissions and increase productivity, and we are happy to work towards these goals with long-time partner Sandvik.”

The Toro LH518iB marries battery-electric and automation technologies. Building on the predecessor Sandvik LH518B, the Toro LH518iB features several design updates and significantly improved field serviceability. The latest version of Sandvik’s intelligent control system enables AutoMine readiness, and AutoMine compatibility will be available for Garpenberg’s Toro LH518iB in the March quarter of 2024.

The Toro LH518iB has dimensions equivalent to the 14-t size class, enabling it to fit in a 4.5-by-4.5-m tunnel. Its ground-up design, powerful electric motors and innovative electric driveline result in a compact size with higher payload capacity and increased visibility, Sandvik says.

Sandvik’s patented self-swapping battery system, including the AutoSwap and AutoConnect functions, minimises infrastructure needs and enables the loader to return to operation significantly sooner than ‘fast-charge’ mining BEVs, the company claims. The battery swap is performed by the loader itself, controlled by the operator in the cabin, without need for overhead cranes or forklifts.

Johanna Øygard, Territory Manager for North East Europe at Sandvik Mining and Rock Solutions, said: “We’re excited to see the productivity and sustainability benefits Garpenberg will gain from Toro LH518iB with AutoMine as we monitor the loader’s performance and production metrics over the next 12 months.”

In Mexico, Torex Gold is set to receive 11 Toro LH518iB battery-electric loaders as part of a 35-unit-strong hybrid fleet for its Media Luna project.

IOCA names REGROUP Australia as preferred primary contractor for Hancock iron ore project

Mineral project development, Mining services, Steel and iron ore, , , , , , , , , , , ,

Alien Metals Ltd’s wholly-owned subsidiary Iron Ore Company of Australia Pty Ltd (IOCA) has named REGROUP Australia as its preferred primary contractor to undertake the construction works, mining operations and haulage services for its flagship Hancock iron ore project in the Pilbara of Western Australia.

IOCA has conducted a competitive market engagement over the previous six months to identify commercially and technically adept contractors to undertake works as part of the Hancock development and operations. This process has involved pre-qualified and targeted proponents submitting bids for specific scopes of works and agreeing to key commercial terms.

REGROUP is, Alien Metals says, a highly renowned and experienced civil construction, mining operator and haulier, having executed projects that exceed A$100 million ($64 million) on multiple occasions. It operates one of the largest privately and independently owned fleets in Western Australia, with clients that include Newcrest Mining, Roy Hill and Element 25.

The selection of REGROUP allows the company to update its financial model as part of the definitive feasibility study (DFS) work streams, Alien Metals says.

As part of the preferred construction contractor award, REGROUP would be in charge of construction of an intersection of the project area at the Great Northern Highway and construction of an access track from the Great Northern Highway to the mine site.

REGROUP has also been selected as the preferred operations contractor for:

  • Mining services (that is inclusive of any drilling and blasting activities); and
  • Haulage services for the haulage of ore from the mine site to Port Hedland.

The award of this contract remains subject to the completion of a positive DFS, approvals, funding and the Board making a final investment decision.

The 2021 scoping study on Hancock showcased a 1.25 Mt/y production profile that would sustain an eight-year life of mine with current resources. The company has said it plans to make its first shipments in 2023, leveraging its direct shipping ore options.

Troy Whittaker, Chief Executive Officer of Alien, said: “Securing REGROUP as a key contractor for the Hancock project is a significant milestone for the company…This is the first step in locking in relationships with contractors on the back of the IOCA sourcing process, securing competitive pricing from contractors, which moves planning for the project forward.

“We are excited to partner with REGROUP, a company that shares our values. REGROUP has set the goal of becoming carbon neutral via the use of a fully battery-powered fleet and the utilisation of solar and wind to help power their sites. That combined with their commitment to advancing indigenous businesses, notably through the championing of Maramara in Western Australia, a majority Indigenous-owned Pty Ltd company, is one of the reasons why we teamed up with REGROUP.”

Michael Still, Managing Director of REGROUP, said: “REGROUP is looking forward to working with IOCA, firstly in the establishment of their mine, as well as the long-term success of the operations from pit to port. We also see a great opportunity to support First Nations business, Maramara, in delivering the civil scope of this exciting project. We would utilise our expertise as a Pilbara-based business and being a partner of a values-based miner such as IOCA, we are eager to see the impact we know this project will have on the Pilbara communities.

“In being a greenfields site, the Hancock project lends itself well to autonomous and electrified solutions for both the mining and bulk haulage fleet. We will continue to work with our partners in Scania and Janus to integrate new and emerging technologies where practical, both on-site and in Port Hedland. The consolidation of the construction and operational activities under one group will facilitate speed to market for IOCA and provides us with the opportunity to embed our expertise early in the project.”

Hexagon, MinRes to ‘transform mining’ with autonomous road train developments

Automation, IoT, Mineral project development, Mining equipment, Mining services, Mining software, Steel and iron ore, , , , , , , , , , , , ,

Hexagon AB has signed a major agreement with diversified mining company Mineral Resources (MinRes) to provide an autonomous haulage solution for a fleet of road trains to run at the Onslow iron ore project in Western Australia, which, the companies say, will transform safety, productivity and sustainability in the region.

The world-first, fully autonomous road trains are a full-site, truck-agnostic solution, leveraging positioning, onboard autonomy and by-wire, fleet management, collision avoidance, world perception and autonomous mission management solutions from Hexagon.

These solutions will be added to Kenworth 330 t road trains (coming with three trailers each), which will run autonomously on MinRes’ 150 km private haul road.

This agreement builds on two major milestones the companies achieved over the last two years in anticipation of rolling out the fully autonomous road trains at Onslow.

In late 2021, Hexagon and MinRes signed an agreement to develop an autonomous road train solution as part of a plan to unlock “stranded tonnes” in the Pilbara of Western Australia. Then, in April 2022, the companies announced a world-first had been achieved with the successful demonstration of a triple-trailer, automated road train platoon in the Yilgarn of Western Australia – each autonomous road train, in this case, hauling 300 t of iron ore.

Andrew Crose, Vice President, Autonomous Mining, Hexagon’s Mining division, told IM that the speed of adoption of this automated solution – from agreement to demonstration, to planned commercial deployment, in a little over two years – was aided by the abilities and efforts of a global team of Hexagon experts.

“Hexagon has staffed a large multi-national team across the Hexagon technologies stack across Perth (Australia), United States, Brazil, Switzerland and Canada to deliver this technology,” he said.

The companies also worked within the framework of the established Code of Practice for Safe Mobile Autonomous Mining in Western Australia to gain the necessary regulatory approvals to move the project forward at such a pace.

Mike Grey, Chief Executive, MinRes, said in the press release: “Automation will remove the risk of driver fatigue, lower operating costs and reduce fuel use and emissions. There’s enormous potential for these vehicles to transform mining across the world.”

Commissioning of the autonomous road trains is expected to fall in line with the go-live date for Onslow – currently estimated for the first half of 2024.

The road trains form an important part of the 35 Mt/y project, ensuring this tonnage is moved from the mine to the Port of Ashburton.

MinRes has said previously that the autonomous road train technology will initially be adopted for its own mining operations, with a view to offering the solution to its Tier 1 customer base as it grows its Mining Services division.

Hexagon recently expanded its autonomy offering with the acquisition of HARD-LINE; a deal that, Nick Hare, President, Hexagon’s Mining division, says allows the company to provide a scalable automation platform that all mining companies can use and grow with.

AngloGold eyes autonomous haulage advantages at Nevada project

AngloGold Ashanti says it is considering the use of autonomous haulage at its Expanded Silicon project, in Nevada, USA, as part of plans to leverage new technology at the in-development asset.

Speaking on a roundtable discussion titled ‘Beyond the hype: how technology can drive mining operations performance’ organised by global subsurface software company Seequent, Marcelo Godoy, Chief Technology Officer at AngloGold Ashanti, said the company was studying the application of autonomous haulage to optimise efficiency and reduce risks at its projects in Nevada.

Discussing automation and robotics as one of three transformational technologies the company is looking to leverage to achieve its net-zero emissions goals by 2050 – electric vehicles and renewable technologies being the other two – Godoy said he saw robots running key production activities at the company’s mines by the time they reach net-zero emission status.

AngloGold has been leveraging automation in its drilling operations, with Godoy noting on the roundtable that the company was seeing improvements in terms of efficiency, precision and safety.

“We also make extensive use of semi-autonomous LHDs in our underground mines, and we are studying the application of autonomous haulage vehicles to optimise efficiency and reduce risks in our projects in Nevada,” he said.

Asked to expand on this by IM after the roundtable, he said: “Our Nevada projects are conceptualised as open-pit mining operations and, at this point, we are only looking at autonomous haulage.

“As far as I know, there is no proven and off-the-shelf autonomous loading technology that could successfully work in the hard-rock environments where we operate. Autonomous loading is still an ongoing technological development and I expect that it will become prevalent in the mining industry before the end of this decade.”

He added that the option of autonomous haulage is being considered at the company’s Expanded Silicon project, which builds off AngloGold’s discovery of the Silicon gold deposit in the Beatty District of Nevada.

In 2022, the company outlined a maiden inferred resource estimate of 3.37 Moz of gold at a grade of 0.87 g/t Au and 14.17 Moz of silver at 3.66 g/t Ag contained within a base of 120.4 Mt. A prefeasibility study is being worked on currently.
