Perenti has announced that its underground mining business, Barminco, has signed a contract extension with IGO Ltd to continue mining at the Nova underground nickel mine in the Fraser Range of Western Australia.

Barminco’s involvement at the Nova mine commenced in early 2015 when it was a greenfield site. This contract extension is worth A$157 million ($106 million) and runs for 29 months.

Mark Norwell, Managing Director & Chief Executive Officer of Perenti, said: “We are immensely proud that Barminco has been present since the beginning of the Nova operation. This contract extension is a testament to the strength of our relationship with IGO and underscores our commitment to collaborating with our clients to generate value together.”

Gabrielle Iwanow, President of Contract Mining at Perenti, added: “Barminco is excited to continue the delivery of the world-class critical minerals operation at Nova. The ongoing safe and reliable mine production showcases how a collaborative approach and willingness to explore innovative solutions can deliver positive outcomes, even amidst significant market challenges.”

In Independence Group’s 2024 financial year, Nova achieved total production of 20,806 t of nickel, 9,922 t of copper, and 735 t of cobalt at a cash cost of A$3.99/lb Ni (payable).

Tax incentives needed to drive electrification of Australia’s mining fleet: EMC report

Environmental, Mining services, Power supply for mines, Sustainable mining, , , , , , , ,

The mining industry is at a crossroads as latest industry insights reveals that electric mines can operate at costs between 56% and 88% lower than their diesel-powered counterparts.

However, just 60% indicate that their next mining operation will transition to electric.

Nearly all (84%) of industry professionals believe that Australia’s mining sector will not meet the government’s goal of achieving 82% renewable energy penetration by 2030.

These startling numbers were published within the ‘Electric Mine Consortium: 2020 to 2024: What we learnt from four years of a radical experiment in cross-company collaboration to build a zero particulae and zero carbon mining industry’ report.

The primary barrier to adopting electric equipment, cited by 76% of miners, is the high capital cost, which is rated 1.5 times more significant than the next major concern: confidence in operational effectiveness.

The report went into this a little more, stating: “There are several reasons why Australian miners have not adopted battery-electric underground load and haul equipment, while around 15% of Sandvik’s Canadian and European order book is battery electric.

“The overriding reason is a lack of clear policy support in Australia. Canada has had clear air quality standards for some time, leading most famously to the Borden mine’s first move to electrify. In support of this are a price on carbon, a 30% capital tax write-off for electric equipment and supporting infrastructure and substantial grants to fund early fleet adoption, such as the Canadian Government’s funding of A$12 million ($8.3 million) to fully electrify Glencore’s Onaping Depth mine.

“In contrast, Australia maintains a generous diesel fuel tax credit that will cost Australian taxpayers A$37 billion between 2024 and 2030.

“For BHP’s iron ore operations in 2023 alone, this tax credit is worth over A$500 million. Unsurprisingly, while BHP has committed to large electrification of its Chilean fleet of 200-plus heavy haul trucks before 2030, any electrification targets in Australia are for the period 2030 to 2040. This is seemingly a policy difference laid bare. As of 2024, Chile imposes a tax on diesel for miners (of around $0.12 per litre), whereas Australia does not.

“The Australian mining industry is also not subject to a universal price on carbon, at any price, unlike Canada and Europe. The closest policy instrument is the Safeguard Mechanism, but this covers only 200 facilities in Australia, of which most are coal mines or LNG facilities. At a 100,000 t C02-e per annum threshold, only a small handful of large iron ore mines are captured as well as very large base metals mines
like Olympic Dam and Newmont’s Telfer gold mine, and downstream alumina and aluminium processing facilities. The vast majority of mines are not subject to a compulsory carbon market.

“In a more subtle way, our mining regulations are also a major challenge to electrification. In Western Australia, ventilation regulations do not differentiate between diesel or electric equipment, which means that the ventilation benefits from using electric equipment, estimated to be anywhere from 20 to 40%, cannot be captured.”

In light of these findings, the industry is urging the government to implement tax incentives to accelerate the decarbonisation of mine sites.

“With diesel particulates posing severe health risks such as lung cancer, and with current Australian standards being over 6x higher than level considered safe by Safe Work Australia for underground miners, electrification is not just an economic opportunity; it’s a health imperative,” Graeme Stanway, Chair of the Electric Mine Consortium, said. “Investing in cleaner technologies can eliminate these hazards and support our commitment to sustainability.”

These findings are based on the first and most extensive collaborative financial modelling exercise on mine decarbonisation undertaken in the Australian mining industry, allowing executives to identify to granular detail the risks, opportunities and pathways to electrify.

Mark Norwell, Managing Director & CEO of Perenti, whose business recently teamed up with their client IGO and business partner ABB, to complete one of the first studies of converting an underground mine’s fleet from diesel vehicles to BEVs, said all stakeholders had a role to play in the shift to mine electrification.

“The study we recently conducted demonstrates that we are getting closer to an all-electric mine and that collaboration is the key to make it happen,” he said.

“We are optimistic that in time an electric underground mine will be the most economic and socially responsible mining method. The electrification of underground mines will deliver significant benefits to health, environment and cost.”

The CEO of Sandfire, Brendan Harris, noted, “Our purpose is to mine copper sustainably to energise the future, so we welcomed the opportunity to collaborate with industry peers to build a deeper understanding of electrification. Renewable energy already accounts for 73% of our electricity needs and we have a decarbonisation plan to reduce emissions by 35% by 2035 and achieve Net Zero emissions by 2050.”

Ivan Vella, Managing Director and CEO of IGO Limited, added, “Our collective journey toward decarbonisation will only be achieved through collaboration and cooperation across our industry. More than just helping demonstrate the value case for mine electrification, the EMC has facilitated the sharing of findings and been an effective advocate for our industry as we pursue our respective decarbonisation roadmaps.”

Context: Mining and environmental sustainability

  • The global mining industry contributes 8% of total emissions;
  • Over 80% of listed miners have committed to net-zero targets;
  • Currently, less than 10% of the Australian mining sector utilises renewable energy;
  • While 15% of Sandvik’s global haul truck production is battery-electric, no BEVs have been sold in Australia to date for on-going load and haul production; and
  • It is estimated 90% of the mining workforce will experience hearing impairment by age 50.

Specific areas of cost reduction

Transitioning to electric mines presents substantial benefits, including:

  • A 100% reduction in Scope 1 & 2 emissions for fully electric mines powered by renewables;
  • Up to 30% reduction in overall operating costs;
  • Up to 50% reduction in energy costs;
  • A 20% decrease in maintenance costs; and
  • A 30% reduction in ventilation costs.

Greenbushes hard-rock lithium mine to undergo Australia-first IRMA scrutiny

Energy minerals, Environmental, Mine operation news, Mining industry recognition, Sustainable mining, , , , ,

Talison Lithium Pty Ltd has announced that its Greenbushes lithium operation will be the first mine in Australia to undergo a third-party independent assessment against the Initiative for Responsible Mining Assurance (IRMA) Standard for Responsible Mining.

The decision to volunteer Greenbushes for IRMA audit reflects Talison’s commitment to responsible mining practices and transparency, the company says.

Located 250 km south of Perth in Western Australia, the Greenbushes lithium operation has been a leader in the Australian hard-rock lithium sector for over 40 years. Renowned globally for its high-quality ore reserves, it is a key supplier of lithium.

The IRMA assessment will be conducted by SCS Global Services, an IRMA-approved independent audit firm, and will include a comprehensive two-stage process: a desktop review (Stage 1) followed by an on-site audit (Stage 2).

Ian McGuire, Interim Managing Director, Talison, said: “We care about a better future – and we know our stakeholders do as well. Whether it be employees, the community, or customers, we want them to know we are committed to responsible mining and production practices.

“To achieve this, we need to provide those affected by our mine with the information they need to engage in meaningful dialogue about where Talison is achieving best practice, and where there is more work to be done. That’s why we’re conducting an IRMA audit.”

IRMA Executive Director, Aimee Boulanger, added: “By volunteering Greenbushes for independent audit against the world’s most rigorous global mining standard, Talison is providing unprecedented transparency into the operations of an Australian mine. They are effectively putting themselves under a microscope and welcoming affected stakeholders to examine their mine and help them make their mine more responsible”.

IRMA is (1) a voluntary mining standard describing best practices to protect people and the environment; (2) an assurance process to measure mines against that standard; and (3) an organisation equally governed by representatives of six affected stakeholder sectors – communities, organised labour, NGOs, finance, purchasers and mining companies – that controls the standard and the assurance process.

Talison, a wholly owned subsidiary of Windfield Holdings Pty Ltd – privately held by Tianqi Lithium Energy Australia, a joint venture between Tianqi Lithium Corporation and IGO Limited (holding 51%, and Albemarle Corporation holding 49% – operates the Greenbushes lithium operation.

The EMC ready to hand over the baton in mining’s decarbonisation race

Environmental, Mining equipment, Mining services, Power supply for mines, Sustainable mining, , , , , , , , ,

The Electric Mine Consortium is not Graeme Stanway’s first innovation rodeo. As the founder of State of Play, a global research platform in natural resources, energy and infrastructure, which also publishes the largest survey on strategy and innovation in mining, he has engaged with many individual and groups of companies looking to spur on mining innovation.

State of Play is the custodian of the EMC and is responsible for bringing almost 20 companies all focused on accelerating progress towards the fully electrified zero CO2 and zero particulates mine together.

Stanway, as Chair of the EMC, has had a front row seat for this journey over the last four years, and was aware the time would come to ‘wrap up’ the consortium’s proceedings – expected on September 30.

“We always knew it was a fixed term,” he told IM. “To be honest, I thought it would be sooner. When we first started, a three-year engagement period sounded about right if things worked well. There is only so long you can keep a core group of companies and people on such an intense innovation journey.”

Four years might sound short – according to Stanway and State of Play’s data it’s the average period that business’ plan their innovation journeys for – but the electrification landscape has changed substantially in that period.

“When we started there was no significant electrification simulation capability, not really any specialised consulting, limited engineering services,” he said. “Now, you can go out and get a study and people are already building mines that are 90% powered off renewables. We also have metrics being introduced that could have a noticeable impact on the way projects go through FIDs.

“The large production equipment is the one thing that is left, but people now know the pathways they need to follow. They would acquire this electric equipment tomorrow if the incentives were there. This would accelerate equipment supply and bring capital costs down, creating a virtuous cycle of adoption.”

He can reference a white paper released by EMC members Perenti and IGO, along with ABB, in May, as an example of how an all-electric mine is possible. It can also be argued that the Australian underground mining sector has caught up and, in some respects, overtaken its rivals in Canada when it comes to electrification. This includes its leading status as an off-grid renewable energy pioneer, as well as hosting the first trial of the world’s biggest underground battery-electric truck at Sunrise Dam in Western Australia’s Goldfields region.

The numbers also back this up, with the EMC starting with five mining companies and getting to 13 in the end. The EMC has also overseen more than 15 non-commercial engagement forums with OEMs and CEOs.

Yet, the EMC’s influence goes beyond this, according to Stanway.

Major and mid-tier Canadian gold miners – Agnico Eagle Mines and New Gold, for example – have generously provided valuable input to specific EMC teams, while a significant amount of suppliers engaged with and learnt from that core group of 13 mining companies.

“Many of the small suppliers used this experience as a product and business development opportunity,” Stanway says. “This also benefitted the mining companies that were able to realise new solutions or services in the marketplace.”

One area that Stanway reflects on as lagging his initial expectations was getting trials off the ground.

The EMC has seen over 70 equipment trials across all fleet types, supplemented by an industry first data sharing platform. This has led to accelerated equipment adoption, but Stanway still thinks there could have been more, particularly with larger production equipment.

“I underestimated how quickly trials would get off the ground,” he said. “Even after everyone’s aspirations were laid out and there was a broad understanding of the technology at hand and the opportunities to be had with these, the momentum slowed in terms of moving to trial and adoption stages.”

He also laments that the initial push to accelerate progress towards the fully electrified zero CO2 and zero particulates mine did not result in an overarching commitment to fully remove diesel particulate matter (DPM) from the underground mining sector.

At The Electric Mine 2024 in May, Chris Carr, Acting COO of IGO, said stricter standards for airborne DPM emissions in Australia and elsewhere would “push electrification a lot harder”.

MasterMined Innovation CEO, Tony Sprague, added to this, telling The Electric Mine 2024 that DPM, and specifically nano-DPM, was “the elephant in the room” and the “real driver of getting diesel out of the underground mine and to achieve the electric mine”. He explained: “There is a new [emission] target that is coming from Safe Work Australia that is not far away. When it’s going to land we’re not too sure, but if it does land it’s going to be very problematic for the industry.”

Stanway said some of this reticence could be tied to the “portfolio mentality” of some of the larger mining companies with legacy assets, and a lack of acknowledgement from leaders on the health and safety risks that come with going underground at existing operations.

“The one thing that hasn’t happened with electrification is the wholesale change in leadership intent to shift as fast as possible,” Stanway says. “A lot of these targets, particularly production equipment conversion, are set to beyond 2030 which is outside of the purview of what gets the attention of the current crop of CEOs.

“I think it is the leadership intent that is needed as much as the technology development in this space. Once the leadership intent ‘flips’, the momentum will step up another gear.”

Progress towards the fully electrified zero CO2 and zero particulates mine has still been vast, he acknowledged, saying that the investment climate and mentality has shifted to help fund new technology adoption.

“People are now open to spending more money in areas that come with uncertain outcomes,” he says, referencing investments in artificial intelligence (AI). “In that regard, it’s not just the quantum of money that has increased, it’s also the willingness to spend money in areas that they wouldn’t have before.”

This shift will benefit other complementary areas of mine electrification and decarbonisation – such as automation, AI and energy sourcing.

Yet, there is no obvious next consortium opportunity on the horizon, according to Stanway.

“Electrification was that rare beast in that it was decarbonisation driven so wasn’t competitive at the time we started,” he said. “These types of opportunities only come around once in a while. In that regard, I’m glad we were able to make such an impact in a short space of time, and we’re able to hand the baton onto the consortium members and the broader industry to advance these areas further.”

The Electric Mine Consortium calls time as it looks for members to take the electrification lead

The Electric Mine Consortium has announced that it will “wrap up” on September 30, four years after the consortium was created with the aim to accelerate progress towards the fully electrified zero CO2 and zero particulates mine.

Made up of a group of leading mining and service companies, the EMC has made significant progress towards achieving this vision and has been a catalyst for significant change within the broader industry, it says.

It was built out of the State of Play report from 2020 simply titled, ‘Electrification’. The State of Play platform was initiated by VCI in partnership with The University of Western Australia; the report was sponsored by The Future Battery Industries Cooperative Research Centre, METS Ignited and Project 412. It covered extensive research aimed to understand the drivers and barriers of mine electrification, identify the key enabling technologies and enable collaboration to accelerate its adoption.

“With electrification kick-started, it has become clear that now is the time to pass the baton on to the individual companies and their leaders to continue the work,” the EMC says.

“The members are well placed to accelerate electrification. Roadmaps have been established and a deep understanding of the available technology is in place. Operational needs have become varied and specialised, so individual companies will drive their own bespoke partnerships and trials with suppliers.”

Given the advancements in technology, and the development of industry capability, it is now feasible to transition to an all-electric fleet, the EMC argues, referencing a white paper released by EMC members Perenti and IGO, along with ABB, in May.

The EMC added: “Members have worked collaboratively over the last few years to raise each other’s maturity levels. It is now up to each company to continue investing in their unique course of electrification.”

The EMC says it leaves a strong legacy of advancing electrification through the member aspirations it has influenced, the initiatives it has developed and the networks it has created.

Over 200 people from participant organisations have been involved in the EMC across many dozens of workshops and meetings annually. CEOs have gathered on multiple occasions to collectively understand the challenges and provide direction, while the EMC has liaised with a wide range of government agencies to help them understand industry needs, particularly in supporting the transition.

Some of the projects the EMC has delivered include:

  • Multiple supplier engagements, such as expressions of interest, to establish member understanding of key technologies across energy storage, energy management and all fleet types;
  • The identification of multiple simulation technologies applicable to mine design, through open-source challenges and supplier engagement, bringing capability to the industry;
  • The development of financial modelling for electric mine design for multiple member assets, demonstrating the electrification business case and design trade-off;
  • Undertaking over 50 member equipment trials across all fleet types, supplemented by an industry first data sharing platform, leading to accelerated equipment adoption;
  • Playing a lead role in progressing shared energy infrastructure in the broader Kalgoorlie Goldfields region; and
  • Introducing carbon measurement trialling resulting in the acceleration of direct tracking of emissions.

Moving forward, EMC companies are committed to continuing the journey through focused collaboration, building on the networks established through the EMC. Members will continue to work with suppliers to develop equipment and progress trials at their sites, according to State of Play. In the coming months members will also communicate how they will continue their electrification plans.

IGO and Perenti herald ‘drop-in’ battery-electric, autonomous drilling solution at Nova

Automation, Base metals, Environmental, Mine operation news, Mining equipment, Mining events, Mining services, Power supply for mines, Sustainable mining, , , , , , , , , , , , , ,

The confluence of automation and electrification in underground mining was spoken of many times at The Electric Mine 2024 event, in Perth, Western Australia, last month, with a whole themed session dedicated to it.

One of the best examples of the two trends converging was observed in a talk titled, ‘Electrification and Automation at IGO’s Nova Mine: Implementation of the Sandvik DL422iE Production Drill.’

In this joint presentation, Brandon Cooper, Senior Mining Engineer of Projects at IGO Limited, and Paul Linabury, Manager of Electrification at Perenti Contract Mining, outlined how this new electric and automated longhole drill could provide the entry point underground miners require to understand the practicalities associated with incorporating such new technology.

“This isn’t the heavy hitter for greenhouse gas or DPM (diesel particulate matter), but what it does is allow us to operate a battery underground and get familiar with it,” Cooper said of the Australia-first DL422iE deployment at Nova.

The Sandvik DL422iE is a fully-automated, battery-powered top hammer longhole drill designed for underground mass mining in 4 x 4 m or larger production drifts, Sandvik says. It can drill vertical and inclined fans and single or parallel Ø89-127 mm longholes up to 54 m in depth using ST58 and ST68 tube rods.

The drill’s electric driveline includes a battery package and electric motor to allow for zero emissions while tramming and also reduced thermal load. The DL422iE also features Sandvik’s patented Charging While Drilling technology; an innovation for reduced battery charging time without the need for additional infrastructure.

Barminco, part of Perenti, purchased the Sandvik DL422iE, which was commissioned and put to work at Nova in July 2023 as part of Barminco’s existing services contract, with the surface drilling remote capacities operationalised in February of this year.

Nova, itself, is a remote operation in the Fraser Range of Western Australia that has traditionally relied on large diesel generators for power. The company has progressively transitioned to renewable generation, which has been reinforced by a 10 MWh lithium-ion battery. These two, alongside the site’s synchronous condensers, allow Nova to produce enough renewable energy to power the production plant and underground mine when the sun is shining, according to Cooper.

This is important for the context of introducing an electric drill to the fleet that is powered off a 75 kWh sodium nickel chloride battery when tramming and the mine grid – via cable – when drilling.

While the electric drill introduction represented an Australia first, Nova has been trialling and deploying battery-electric equipment for several years. It has three Zed 70 Ti light utility vehicles (battery-electric conversions of Toyota Landcruisers) in its fleet from Zero Automotive, has trialled the Bortana EV – another electric light vehicle – has one BME ITC L120H battery-electric integrated tool carrier to its name and is expecting to add another machine to its fleet by the end of the year – a Normet Charmec MC 605 V(E) SD battery-electric emulsion charge rig.

This breadth and depth of experience allowed Cooper to look across the industry’s underground mine electrification equipment offering and draw some parallels at the event.

“Introducing a battery-electric drill has, at this stage, a lot more chance of being seamless and successful with far less operational changes needed to be made compared with a truck or a loader,” he said.

The proof of this statement was in the presentation, and some of the specific operational highlights he and Linabury outlined.

From initial deployment in July 2023 to the middle of May 2024, IGO had drilled 50,750 m with this rig, with Cooper saying the site typically drills longholes to 45 m lengths. When compared with the diesel-powered DL421 rig the operation was previously using, the DL422iE was 20% more productive than the DL421 rig’s 12-month average drilling rate of 5,000 m/mth.

Looking at the automated elements on board the Sandvik rig – the first battery-electric vehicle equipped with Sandvik AutoMine® for surface remote drilling and automation – Cooper highlighted higher metres drilled, reduced hole setup times and increased flexibility.

He provided some colour here: “Auto fan drilling enables the drill and blast engineer to put a drill design on a USB stick and give it to the operator, where the operator plugs it into the rig’s USB port to view a digital map of what they’re drilling. The rig itself will automatically test each planned collar location and alert the operator if a hole needs to move; allowing them to shift the collar and leave the toe in place, or shift and drill a parallel hole.” These amendments to the original plan are recorded, with the engineer able to analyse the information on the updated file later.

Following this process, the rig can be setup to drill an entire fan without any operator input.

The second automation advance Cooper highlighted was the ability to carry out drilling from the surface in a cab. The company has been using this facility to drill during shift change or during re-entry. “That feature is netting us 770 m on top of what we have been getting every month,” Cooper said. “And I don’t think we are taking full advantage of it just yet; I think there are more gains to be had.”

While the machine is meant for battery-electric tramming, Cooper said there had been glimpses of the rig’s ability to also drill off battery, relaying one occasion where an electrician was able to repair a “jumbo box” at the same time as the operator carried out a 25 m long hole using battery power.

The battery-electric rig has also required some changes to the way operators work, with Cooper noting that the 75 kWh sodium nickel chloride battery did not provide enough power for the machine to tram 3.3 km (on a 1:7 incline) from the bottom of the ramp to the top. Nova operators had got around this issue by carrying out an opportunity charge 850 m from surface by the rod-storage cuddy, allowing the operator to offload drill rods at the same time.

“These BEVs require changes to the way we work,” he said. “If we can integrate those changes into our existing work practices to minimise the changes to the operators, we will get a better result.”

Linabury, meanwhile, highlighted how the services provider was identifying the new risks and opportunities that were emerging from battery electrification during deployments such as this.

Examples included recognising the increased number of electrical isolation points on a battery-electric drill and creating a live line indicator to identify when current is running through these, charging the battery to below full capacity to make the most of downhill regeneration and more closely interrogating classifications given by systems such as the battery management interface.

In the Q&A session at the end of the presentation, Cooper summed up the IGO rationale for bringing this new battery-electric and automation-enabled machine into the Nova fleet: “As we have shown with the DL422iE, you can essentially drop this in and change very little about the way you operate normally, but at the same time you get a chance to play around with: ‘What does my emergency response look like for this new drill? How do my supply chains have to change for parts? How do my skillsets need to change for people? What do the operators need to be made aware of?’

“You can solve all of those problems, and a lot of those learnings are then directly transferable for when you start tackling the bigger problems of heavy machines.”

Such learnings would allow the company to have a much clearer picture of what it would take to fully electrify an underground mine in the future, he concluded.

RCT collaborates with Barminco on latest automation project at IGO Nova

Today, RCT’s agnostic automation can be found at many of Barminco’s operations throughout the Goldfields region, and now there is one more to add with the completion of its most recent project at IGO’s Nova mine.

Despite the site’s existing automation infrastructure, when it came time for upgrading, RCT Automation was selected as the preferred supplier by Barminco, a subsidiary of global mining services group Perenti.

“Technology and innovation are a key focus for Barminco, and we appreciated the simplicity of the RCT Automation solution – quicker setup times and ease of use for our operators,” Darren Kwok, Head of Mining Electrification and Technology for Perenti Contract Mining, said.

The loaders are operated from the safety and comfort of Automation Centres, which have been situated both underground and on the surface of the mine.

To enhance sustainability and cost efficiency, existing cabins were repurposed, refurbished at RCT’s Kalgoorlie branch.

Kalgoorlie Branch Manager, Rick Radcliffe, said: “The cabins required sandblasting and painting before we lined them with fridge panelling and fitted them out with RCT’s state-of-art ergonomic chair and operations centre.”

In addition to providing agnostic automation, RCT was able to work with Barminco to use both the existing underground communications technology and supplement it with the RCT connect to ensure we provide the best and most cost-effective solution for the client. The team also provided extensive operator training to empower site and ensure self-sufficiency with the technology.

Kwok added: “We have a good working relationship with RCT, and this extends beyond just the service delivery and project delivery.

“Outcomes from the project have been positive and we have worked collaboratively with RCT to ensure any operational concerns raised were reviewed and their product offering improved based on our feedback.”

Radcliffe said: “When two companies have the same goal of implementing quality products into a technology focused operation, they will always be successful, and that was certainly the case at Nova.

“We are looking forward to working with Barminco over the coming months to assess the impact that the project has had.”

ABB, IGO and Perenti on collaborating for full mine electrification

An industry panel discussion on the potential of electrifying IGO’s Cosmos underground nickel project at IMARC 2023 today highlighted the opportunities, risks and complexities associated with ‘greening’ a brownfield mining project at the moment.

Back in June, Perenti and ABB, in collaboration, were awarded an inaugural contract by IGO to undertake a study for the full underground electrification of the project, in Western Australia.

This study was to see experts from Perenti and ABB work side by side with IGO to provide a pathway for the optimum design of mine electrification at Cosmos. All aspects of electrification were to be considered in the study, including:

  • Mine design optimisation for electric operations;
  • Production and operating philosophy;
  • Fleet selection;
  • Power distribution and electrical infrastructure design;
  • Electrification system and battery management;
  • ESG and safety impact analysis; and
  • Cost modelling of both capital and operating expenditure.

At IMARC today, on the ‘Going All-Electric: Collaborating to Fully Electrify IGO’s Underground Cosmos Nickel Project’ panel discussion, chaired by Emma Jones, Innovation Management Lead, Southern Hemisphere, GHD, all three companies had representatives on stage to flesh out some of these bullet points, with the result being a fascinating discussion on implementing what is still a revolutionary concept.

The Cosmos study is split into three distinct parts with the companies currently half way through the process.

Both Chris Carr, Head of Technical Services at IGO, and Darren Kwok, Head of Mining Electrification and Technology, Perenti, admitted that the task at hand was highly complex.

Carr said the process would be much easier in a greenfield mine, with the potential ventilation and refrigeration cost reductions that would come with introducing electric machines likely to “pay” for the new equipment required.

At the same time, he acknowledged that the networks and communication would need to be improved to effectively run an all-electric mine to allow operators to know what vehicles had what state of charge and deploying these machines in the optimal way.

“This could potentially see whole sites use Wi-Fi or 5G for better data transmission,” he said. “At the same time, we would know where every vehicle is and where every vehicle is going, providing the opportunity for ‘true’ collision avoidance.”

Kwok said there was likely to be a “flow-down effect” when electrifying equipment, which would have an impact on how mines plan, schedule and operate. “We need a holistic view of a mine,” he said, explaining that “just in time” mining would not work in an all-electric operation where energy management is a key concern.

Kwok added: “We also have to link the fleet together with the rest of the operations – that is the secret sauce here.”

Mehrzad Ashnagaran, Global Product Line Manager – Electrification and Composite Plant, ABB, said any mining company looking to fully electrify their mines needed to recognise that they were working with “immature technology” that cannot meet all of their requirements.

“The design of an all-electric mine is different to the vision we originally had,” he said. “This is why we need to break the process down into manageable projects for a phased approach that can allow customers to start decarbonising now.”

This is where the company’s eMine™ approach comes in, providing a roadmap of solutions on the way to longer-term electrification goals.

“In reality, the solution we are offering today may not be the same one we offer companies in five to 10 years’ time,” he added.

There was also an engaging exchange on the risk management associated with embarking on this exercise.

Ashnagaran said, for ABB, the Cosmos study and other all-electric projects the company is working on would see its vendor agnostic and interoperable approach tested and scrutinised.

“The whole eMine philosophy, however, is that no-one can go on such a journey alone; we need to collaborate with partners,” he said.

Kwok said the study allowed the service provider to learn and understand the terms of how electrified mining can practically work.

“We, at Perenti, already understand what ‘good’ looks like [from an operating perspective]…and we also understand what change looks like at a mine site,” he said, adding that the company already has electric machine data to pull into such studies.

Carr said building ‘the electric mine’ is both a risk and an opportunity, with the mining company prepared to financially back most of the expense associated with this as it had, potentially, the most to gain from a successful outcome.

He also added a bit of wider IGO context to reinforce the point.

“At IGO, we invest A$70 million ($44.5 million) a year on exploration, putting drills into the ground,” he said. “Not all of those holes are deemed a success, but they allow us to keep building our knowledge,”

The same is true for this all-electric Cosmos study.

“Regardless of the outcome, we will learn a lot,” he said. “We are driven to be the ‘first to be first’ here; first to be second simply does not work for us.”

The world’s mining and resource leaders are heading to Sydney, New South Wales, for the International Mining and Resources Conference (IMARC) from October 31 – November 2 in what has become a “grand slam” event of the industry, globally, event organisers says.

IMARC Chief Operating Officer, Anita Richards, said this year’s event was looking to be the largest ever, with over 520 speakers from global giants such as BHP, Fortescue, MMG, Gold Fields, Wesfarmers, Worley, Perenti, IGO, the US Departments of Energy and Defense and the ICMM, coming together to collaborate on themes including digital transformation and innovation; sustainability, social value, environmental resilience, people and culture; trade, investment and project opportunities; and energy transition.

She said: “The mining and resources industry is evolving rapidly to meet the growing energy demands of today while developing the minerals needed for a decarbonised economy – under unprecedented scrutiny from communities, regulators and investors.

“IMARC 2023 comes at a time when explorers and miners are diversifying portfolios to align with future demand, triggering the highest level of M&A activity across both mining and METS we have ever seen.”

This year’s conference will see the return of the IMARC NextGen Program, which will provide an opportunity for 200 NSW school children to learn about the diverse and exciting mining and resources industry.

IMARC 2023 also features:

  • A special ESG focus on creating social value;
  • An extensive look at First Nations engagement, human rights and transparency;
  • A look at best-practice mine rehabilitation;
  • A global perspectives on heritage and environmental custodianship and economic development;
  • A return of the successful Balance for Better Program which promotes equality, diversity and inclusion across all areas of the mining and resources sector.

Richards added: “Mining and resources have never been more important for sustainable economic, social and innovative development across the globe. We need more exploration and development to match surging demand for the critical minerals that are central to the global energy transition. IMARC 2023 is where the most important conversations are being held about how mining and resources can help achieve global development sustainably and equitably.

“IMARC is a key forum to address these challenges, and the global profile of the event is reflected in delegations already confirmed from India, Saudi Arabia, Ecuador, Chile, Mongolia, United States, South Korea, Japan, Germany and many more.”

At IMARC 2023 a range of new features have been added to the program. These include the Low Emission Technology Australia session to help accelerate innovation in the clean technology sector, the 4,000 sq.m IMARC Mining Pavilion with over 150 exhibitors present and the final of the Unearthed Global Innovation Games where the winners will be announced and their technology displayed.

IMARC 2023 will take place at the ICC Sydney from October 31 to November 2 and will be a celebration of what has grown into one of Australia’s biggest business events, with a record 8,500 delegates from over 120 countries, including upwards of 50 government delegations expected to attend, organisers say.

International Mining is a media sponsor of IMARC 2023 and will be in Sydney reporting on the event.

Barminco and RCT partner on ‘world first’ agnostic remote installation of Cat 2900 XE

Barminco has enlisted the help of RCT to carry out what it believes to be the world’s first agnostic remote installation on Caterpillar’s R2900 XE diesel-electric underground loader.

The mining services company will be using the R2900 XE loader which has a diesel engine and electric driveline at the IGO-owned Spotted Quoll underground mine, in Western Australia.

Built on the platform of Caterpillar’s most popular underground loader, this new LHD – which was previewed at MINExpo 2021 in Las Vegas – features optimised lift arm and component geometry plus load-sensing hydraulics to improve breakout force by 35% over the Cat R2900G, Caterpillar claims.

RCT’s Kalgoorlie Branch Manager, Rick Radcliffe, said: “Technology and innovation are two of Barminco’s core components, so it made sense they chose RCT to carry out the installation of this automation project. We are receiving a lot of interest in this project as it is a hybrid loader which reduces fuel burn resulting in low diesel particulates, which is something companies are looking at doing to mine more sustainably in the future.”

This project is currently underway with RCT’s Kalgoorlie branch completing the installation.

The world’s first R2900 XE was delivered to Western Australia-based Westgold Resources, with the gold miner having since agreed to purchase another six of these loaders.
