Perenti Group’s underground mining business Barminco is to further strengthen its relationship with Evolution Mining, having been awarded a new A$60 million ($42 million) contract to carry out diamond drill work at Cowal Gold Mine operations in New South Wales, Australia.

The four-year contract will see Barminco use state-of-the-art drill rig technology to improve safety, performance and productivity, it says.

It’s the second contract to be secured by Barminco at the Cowal operations in two months, after recently winning a A$520 million underground and development contract.

This latter contract will see Barminco carry out all underground development and production works at the underground mine where it is currently developing an exploration decline.

Last year, the Evolution board and regulators approved the development of the Cowal Underground Mine, which is set to provide a higher-grade ore source that will be blended with the current E42 open pit and stockpile ore. The development is part of the group’s goal of Cowal producing 350,000 oz/y of low-cost gold and extending the operation’s mine life.

Gekko Systems improves carbon sampling accuracy, safety at Cowal gold mine

The technical team at Gekko Systems has released further data that, it says, supports the benefits of new technology that optimises carbon management systems in gold processing facilities.

Optimising carbon management in the carbon-in-leach (CIL) circuit reduces gold solution losses and improves gold circuit recovery. This is essential for sites needing to offset higher inflationary costs with improved revenue, Gekko says.

The case study, released today, reviews operational performance of Gekko’s Carbon Scout at Evolution’s Cowal Gold Operation in New South Wales, Australia.

The Carbon Scout is a self-contained, ground-level sampling system that measures carbon concentration, as well as pH, DO and, more recently, has an option to measure gold loading on carbon using XRF technology on an hourly basis. Optimising the Carbon Scout for site conditions allows for more accurate, reliable and repeatable measurement of the carbon inventory of the CIL
circuit, Gekko says. Automating data collection and process actions such as carbon transfer, meanwhile, reduces operator risk exposure and person-hours (previously dedicated to the manual data collection tasks).

Installation of the Carbon Scout at Cowal commenced in February 2019, with the Gekko Systems Digital Services and Technical team providing ongoing support – both onsite and remotely – in the initial months of the system’s operation to ensure maximum availability was achieved and Evolution Mining was receiving the full benefit of the Carbon Scout.

After a few months of integration with the SCADA system, the Carbon Scout was able to use the data and analysis to facilitate automated transfer of the carbon inventory within the circuit to maintain pre-determined concentrations, according to Gekko.

The Carbon Scout at Cowal has successfully reduced operator exposure to slurry containing hazardous materials including cyanide and improved sample authenticity by collecting a more representative and repeatable sample, Gekko said in the case study.

The other critical success achieved by the Carbon Scout is its ability to take a larger CIL tank sample that is more representative. This is achieved by the Carbon Scout drawing from deeper within the tank, where more superior slurry-carbon mixing occurs, and a larger sample of up to 20 litres is taken, which is 10-20 times the typical manual sample size. Additionally, the sample is extracted from a consistent point each time the Carbon Scout cycle samples from that tank.

Gekko concluded: “Optimising the Carbon Scout for site conditions allows for more accurate, reliable and repeatable measurement of the carbon inventory of the CIL circuit. Utilising these measurements and integrating with a plant’s SCADA system, the automatic control of carbon concentrations through the CIL circuit can be achieved. Automating data collection and process actions such as carbon transfer reduces operator risk exposure and man hours previously dedicated to the manual data collection tasks.

“The improvement derived from the utilisation of the Carbon Scout should lead to increases in circuit recovery by reducing soluble gold losses.”

The Carbon Scout was originally the brainchild of Curtin University’s Gold Processing team, led by Dr Teresa McGrath and Bill Staunton. Curtin University selected Gekko Systems as its commercialisation partner.

Staunton noted that “real-time data collection instrumentation and related analysis is essential to the future of the gold processing industry”.

Gekko Systems’ Technical Director, Sandy Gray, said: “The increasing installation base of the Carbon Scout globally is providing a fantastic baseline of evidence that supports the benefits of quality data collection and automation.”

Electric Mine Consortium launches Surface Long Haul EV Challenge

The Electric Mine Consortium (EMC) – made up of Evolution Mining, South32, Newcrest and a total of 21 major industry players – has launched a Surface Long Haul EV Challenge, calling on the automotive and electric vehicle (EV) industry for solutions in its mission to establish decarbonised mine sites.

The EMC’s call out to companies in the tech, renewable and manufacturing industries is looking for ground-breaking solutions to long haul EV trucks and associated charging infrastructure for mine sites and global supply chains.

Driven by collective demand for electric equipment across the EMC’s operating sites, spread over six continents, the consortium is looking to form synergies between mining and non-mining industries to accelerate decarbonisation solutions across the industry – the mining industry currently contributes 8% of the globe’s emissions.

EMC Founder and Director, Graeme Stanway, explains there’s currently no equipment and associated infrastructure solution that’s available at scale, in line with mining companies’ operational needs.

“The mining industry’s path to electrification is where the car industry was 10 years ago,” Stanway said. “We have the technology, but it needs acceleration and adaptation to meet the needs of varied mine sites across the world.”

He says there’s a big opportunity to recreate mining from a place of siloed communication between companies to a point where collective strategy drives the industry to drastically reduce and ultimately eliminate carbon emissions, through electrification.

“We have the world’s largest data platform of shared knowledge surrounding renewables in mining,” Stanway said. “Through the Surface Long Haul EV Challenge, we’ll be working to accelerate, pilot and convert all new fleets to electric with detailed use case studies for knowledge sharing across the industry.

“If we can solve this for our freight in mining, imagine the impact we can have on the rest of the transport market. Mining has a great opportunity to flip the perception…from being seen on the wrong end of the ledger, to being a leader.”

The EMC is now seeking businesses who can design or supply electric long-haul equipment solutions.

Draslovka eyes base metal leaching prize with MPS glycine technology

Draslovka Holding made its presence felt in the mining chemicals space about a year ago when it announced plans to acquire Chemours Company’s Mining Solutions business, a deal that has since seen it become one of the largest North American producers of solid sodium cyanide.

This acquisition, completed in December for $521 million, also laid the groundwork for a separate transaction that could see the Czech Republic-based company diversify into the in-demand battery metals arena.

Australia-based Mining & Process Solutions (MPS) had been on the Mining Solutions business radar for at least two years prior to the Draslovka transaction, according to James Stockbridge, Director of Draslovka Mining Solutions. Stockbridge, formerly of Chemours and DuPont, said that his team at Draslovka realised MPS had something on its books that could solve many of the challenges the industry was experiencing and transform mining solutions by using an amino acid called glycine.

“For more than a decade now, the industry has recognised that orebodies are becoming lower grade, processing them is becoming more complex and the environmental regulations associated with leaching are becoming stricter,” Stockbridge told IM.

“It is the challenge of our time, and we think MPS has something quite unique to offer here.”

With roots in the gold technology group at the renowned Curtin University in Western Australia, MPS’ glycine leaching technology has the potential to change both the gold and base metal leaching space.

In gold, MPS’ GlyCat™ process was invented to reduce cyanide consumption while maintaining gold recovery for gold ores from deposits containing nuisance copper. GlyCat has been designed to enhance the dissolution of gold and copper in gold/copper ores where glycine is used as a catalyst with cyanide in a cyanide-starved leaching environment. It doesn’t replace cyanide, but, in fact, enhances its leaching capabilities by dealing with the high-cyanide consuming copper within these gold-copper orebodies.

In copper, nickel, cobalt and zinc leaching, GlyLeach™ is able to leach the targeted metals with enhanced selectivity compared with conventional methods. It will solubilise copper, nickel, cobalt and zinc, while gangue minerals such as iron, manganese, silicates and carbonates remain in the leach residue, MPS says.

Both technologies are environmentally safe, work effectively at alkaline pHs and ambient temperatures (with no heating cost or pressure vessels) and come with low operating costs due to their low consumption and recovery/recycling traits, according to the company.

While it is the gold side of glycine leaching testing that has, so far, taken the headlines thanks to several trials with mining companies in Australia (including Evolution Mining) and the technology’s potential ability to partially replace cyanide in the leaching process, Stockbridge and his colleague Jackson Briggs (Corporate Development Manager for Draslovka) said Draslovka was most excited about what the technology could offer the base metal space.

Briggs said: “It gives us the opportunity to expand our leadership position in gold leaching agents into base metals. At the same time, it also allows us to incorporate our expertise in that chemistry and chemical manufacturing side of things.”

Stockbridge – not wanting to give away too much – hinted at how this latter opportunity could play out.

“The leaching technology will also influence the way you, for instance, operate, monitor and control the plant,” he said. “This process will be different, and we will be bringing in new technologies to cater to this.”

Considering Draslovka can produce glycine from its existing hydrogen cyanide production footprint, there is potential for a very smooth integration on the supply chain side of things.

Asked to quantify some of the benefits of the technology, Stockbridge was happy to point out GlyLeach’s potential to “simplify the flowsheet” for, say, nickel production, removing the smelting aspect and resultant ore transportation – providing capital and carbon footprint benefits.

Briggs added: “It can change a lot from ore-to-ore with GlyLeach, but, in a really strong business case, you are looking at a 25% reduction in processing costs.”

This is on top of a 10-35% improvement on the recovery side, compared with conventional leaching, Stockbridge said, citing “proof of concept” studies.

As for GlyCat, the sweet spot – as already hinted at – is in gold-copper orebodies where copper is a large cyanide consumer, with the technology allowing cyanide to work more efficiently and effectively.

Both technologies recently featured in OZ Minerals Ingenious Extraction Innovator challenge outcomes publication, while GlyCat has also been the subject of a one-off study looking at combining it with Sixth Wave Innovations’ IXOS® molecular imprinted polymer for gold extraction.

Australia’s Future Battery Industry Cooperative Research Centre, which is sponsored by the likes of Sandfire Resources, Barrick Gold, Coda Minerals (previously Gindalbie Metals) and Poseidon Nickel, is also coordinating some of the work towards commercialising GlyLeach.

There is a strong business case for both technologies first being deployed at scale on tailings deposits that have been deemed to have no associated value – a point both Stockbridge and Briggs acknowledged.

Briggs said: “In terms of accelerating the development of the technologies, there are tailings deposits and waste piles situated all over the globe with high amounts of precious and base metals that have not been extracted due to the limitations and economies associated with current processing technology. We could provide an economic way of extracting those.

“It would also provide us a project with much reduced start-up times compared with, say, a greenfield project.”

Stockbridge added: “We have carried out some work on this type of application before and believe there is the potential to extract 50% of the nickel that they couldn’t access with existing technology by using GlyLeach.”

From the mining company perspective, deploying a new technology on material already written off comes with a lot less risk too.

That is before appreciating that the material won’t have to be smelted on site, that the process produces no free cyanide and that gangue materials do not come out in solution.

It is no wonder the Draslovka duo are excited about the technology’s potential; GlyLeach in particular.

“The ability to help nickel and copper miners produce more metal to rescue some of these deposits that have been forgotten or under-developed because of technology limitations and be able to do so in a way that is more environmentally friendly is exciting.

“Potentially, this technology could help localise more electric vehicle supply chains by removing the need for smelting and providing a cost-effective and environmentally friendly means of extracting metals.

“We cannot wait to get started.”

MLG Oz Ltd is set to extend its relationship with Evolution Mining Limited after being selected as its preferred service provider to service its Mungari operation, located in the Goldfields region of Western Australia.

The award of the new contract for the provision of haulage and integrated site services issued under Evolution’s wholly owned subsidiary, Evolution Mining (Mungari) Pty Limited, is for an initial contract term of two years, with a provision for a further one-year extension at Evolution’s discretion. The contract, MLG says, leverages its large Kalgoorlie-based resourcing pool and off-road haulage assets.

The Mungari district, now under the single ownership of Evolution, has a significant mineral endowment with a large portfolio of resources delivering long term feed options to the company’s centrally located Mungari processing infrastructure. Mungari produced 115,829 oz of gold at an average all-in sustaining cost of A$1,453/oz ($1,003/oz) in the financial year ending June 30, 2021.

MLG founder and Managing Director, Murray Leahy, said: “We commenced our first contract with Evolution less than a year ago and we are delighted to be awarded this opportunity to enhance our long-term relationship. This contract marks a significant milestone in our pursuit to provide superior integrated services to our customers.”

The new contract will see annualised revenue with Evolution effectively double to some A$15-$18 million, MLG said. The company’s scope of works builds on the recent integration of the Kundana operations into Evolution’s Mungari portfolio, with MLG engaged to service the combined sites bulk haulage and road maintenance requirements under a single service provider arrangement.

Barminco to help Evolution go underground at Cowal gold mine

Perenti’s Barminco underground mining business has been awarded the contract for all underground development and production works for Evolution Mining’s Cowal Underground project in New South Wales, Australia.

Barminco, a leading global underground mining services business, is currently developing an exploration decline and conducting diamond drilling services at Cowal.

Last year, the board and regulators approved the development of the Cowal Underground Mine, which is set to provide a higher-grade ore source that will be blended with the current E42 open pit and stockpile ore. The development is part of the group’s goal of Cowal producing 350,000 oz/y of low-cost gold and extending the operation’s mine life.

Perenti said the award of this new contract significantly expands Barminco’s scope at the site to include the development of a second portal, all underground development and production works, and associated underground mining services required to support the continued mill feed of underground ore.

Mark Norwell, Managing Director and CEO of Perenti, said the award of the Cowal contract aligns with Perenti’s strategy of increasing its earnings in top-tier regions and with top-tier clients.

“The Cowal contract represents one of the largest underground mining projects in Barminco’s history, generating revenue of nearly A$520 million ($373 million) with an initial term of four years, from a contract commencement date in early July 2022,” Norwell said.

“This contract award represents not only a significant expansion and continuation of our first underground contract in New South Wales but is also a fantastic opportunity for Perenti to build on our strong working relationship with Evolution, one of Australia’s premier gold mining companies.”

Norwell explained that, between now and the end of Perenti’s 2022 financial year, the company will commence investing the capital required for this project with revenues and earnings ramping up in the 2023 financial year and beyond.

“The project represents a significant improvement to our Australian underground earnings base and will generate strong project cash flows and returns in support of our capital allocation and investment,” he added.

Electric Mine Consortium partners with AWS on world-first mine decarbonisation platform

Australia’s Electric Mine Consortium (EMC), made up of some of the world’s leading mining and service companies, has announced it is working with Amazon Web Services (AWS), an Amazon.com company, to accelerate the electrification of mine sites globally.

Announced at AWS Summit 2022, EMC is using AWS’s depth and breadth of services, including machine learning, business intelligence and storage, to build the world’s first mining data platform, to capture real-time information on mine decarbonisation from sites globally.

To drive decarbonisation, mining companies can use the platform to measure energy storage levels and electrical infrastructure use from global mine sites to accelerate the creation of a cleaner, more electrified future in mining, EMC said.

Co-founder of the EMC, Graeme Stanway, says the platform can help enable EMC members to share sustainability insights and analyse the outcomes of adopting electrified mining infrastructure and sustainable operations.

“The way we generate, store and harness energy around the globe is changing drastically,” Stanway said. “EMC’s collaboration with AWS will help see us at the forefront of this change, driving the mining industry’s electrification at scale.”

Stanway said the industry is crying out for tools to decarbonise due to tightening government emission reduction targets, increasing environmental, social and governance pressure, and the industry being responsible for 7% of the greenhouse gas emissions globally.

“Like the electric vehicle industry, electric mines are the future” Stanway said. “Not only can they be safer through the eradication of diesel particulates, pollution, noise and vibrations, they can also be more targeted, precise and effective when it comes to mining, and yield stronger results than traditional mines with minimal ground disturbance.”

As part of the initiative, EMC created a “data lake” using Amazon Simple Storage Service (Amazon S3), a cloud object storage service, that can securely store thousands of datasets from the consortium’s mines, including data on energy consumption and renewable energy infrastructure output.

EMC can then clean the data and run data pipelines using AWS Step Functions, a low-code, visual workflow service; AWS Glue, a serverless data integration service; and AWS Lambda, a serverless, event-driven compute service. AWS Glue can provide EMC with data catalogue functionality, and AWS Lake Formation, a service that makes it easy to set up a secure data lake in days, can deliver security and access control.

Amazon QuickSight, a business intelligence service (screenshot pictured), can allow everyone in the consortium to explore and understand mining data through user-friendly interactive dashboards that identify efficiency practices that may reduce emissions, according to EMC.

Also, using Amazon SageMaker, a fully managed service to build, train, and deploy machine learning models, EMC can train machine-learning models to predict energy usage spikes at mines and track the carbon efficiency of deploying sustainable energy infrastructure.

Sarah Bassett, Head of Mining and Energy, Australia at AWS, said: “Data capture and analysis is essential to mining operations, and AWS is helping consortium members to share their critical datasets and collective insights to drive the digitisation and evolution of the industry. I am excited to be collaborating with the EMC and its consortium members to improve the design of mines globally and accelerate the industry’s journey to decarbonisation on the global scale.”

The EMC is a growing group of over 20 mining and service companies. These companies are driven by the imperative to produce zero-emission products for their customers and meet mounting investor expectations. Thus, the objective of the EMC is to accelerate progress toward the zero-carbon and zero-particulate mine through:

  • Resolving key technology choices;
  • Shaping the supplier ecosystem;
  • Influencing policy; and
  • Communicating the business case

The EMC is emerging as a key vehicle for the decarbonisation of the mining industry, particularly for underground operations, and will remain responsive to the rapidly changing external environment.

Members include OZ Minerals, Newcrest Mining, Gold Fields, IGO, South32, Blackstone Minerals, Evolution Mining, Barminco and Iluka Resources.

Five teams have been selected to join the Think & Act Differently (TAD) ideas incubator, powered by OZ Minerals and Unearthed, tasked with developing and testing an open architecture simulation platform to develop electric mine designs, with the goal to achieve zero scope one emissions.

Last September, the Electric Mine Consortium launched the Electric Mine Simulation crowd challenge in partnership with the (TAD) ideas incubator, noting that electrification of mine sites remained a critical step change needed for the mining industry to achieve a zero-carbon future.

“Switching to electrified solutions and renewable energy represents a transformational shift that will change the way mines are designed,” OZ Minerals said. “This challenge is about using simulation to understand the impacts of electrification on mine design, infrastructure and energy management.”

The crowd challenge closed in November last year and attracted 179 participants from 36 countries, resulting in 23 submissions. Five teams have now been selected to join the TAD incubator where they will be supported to develop and test their simulations.

Finalist teams include:

  • Polymathian – Colin Eustace, Michael Dallimore, Steven Donaldson and Mitchel Grice are experts in solving complex planning and scheduling problems for the industry, OZ Minerals said. Their solution is to provide a widely used scalable simulation model platform to model large and complex operations, from mining and processing to full supply chain operations;
  • SimGenics – Abrie Venter and Kobus Viljoen are using a software platform that can integrate continuous and discrete-event simulation tools from multiple vendors into one solution;
  • Simulation Engineering Technologies – Jaco Botha, Henk Jenkinson, Fredrik Sundqvist and Marco Agas are the team behind a mine simulator (SimMine®) that allows for the construction of a complete mine simulation, including development, production and ore handling systems;
  • MathWorks – Wilco Volwerk, Peter Brady, Ruth-Anne Marchant and Sam Oliver are using a mathematical computing software that can be used to model dynamic, discrete and continuous processes with multiple time scales to create a mine simulation framework; and
  • First Mode – Aidan Morgan, Jan Haak and Clara Sekowski represent a creative engineering company, using modelling and simulation to inform design decisions and optimise the use of technology.

The teams will work together to explore and develop concepts for the development of an open architecture simulation platform to develop electric mine designs, with the goal to achieve zero scope one emissions. A use case for testing the value of simulation will be provided by OZ Minerals’ copper-gold mine, Prominent Hill, with further use cases developed in collaboration with the Electric Mine Consortium member companies.

The TAD Incubator program is a supportive environment that includes funding, technical mentoring, opportunities for collaboration, capability uplift and access to mining data and mining operations, OZ Minerals said. The teams will be supported by mining business improvement specialists from Imvelo, Sharna Glover and Alan Bye and Simulation SME Luigi Barone, an internationally recognised expert in artificial intelligence.

Brett Triffett, OZ Minerals’ Transformation Technologist, said: “This challenge will help us learn about the power of simulation together with some really talented and collaborative people, as we accelerate progress towards a fully electrified zero carbon zero particulate mine. The benefit of crowdsourcing, particularly in an area where ideas may come from outside our traditional mining networks, is that we can scour the globe to find start-ups, academics and individuals that we would not have otherwise had encountered.”

Multiple mining companies from the EMC will be able to collaborate on the outcomes of this experiment and we’re excited to see what we can learn about the process as well as the technology. The teams will work together over a three-month period to develop simulation concepts.

OZ Minerals, IGO South 32, Blackstone Minerals, Evolution Mining, Barminco and Gold Fields have committed to significantly reducing their carbon footprint. These seven mining companies, along with a number of partner companies, have come together to form the Electric Mine Consortium, a collaborative group seeking to accelerate progress towards a fully electrified zero carbon and zero particulate mine.

The TAD incubator is powered by OZ Minerals and is focused on themes that prioritise social and environmental responsibility for the future of mining.

Epiroc shows off sustainability credentials in another record quarter

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

In a quarter characterised by high customer activity and a strong demand for aftermarket services, Epiroc had another reason to be positive with the validation of its 2030 sustainability goals by the influential Science Based Targets initiative (SBTi).

Further records were broken in the December quarter – this time it was revenue (coming in at SEK11.1 billion (US$1.19 billion) and operating profit (coming in at SEK2.59 billion) – as the company continued to benefit from its in-house efficiency programs; value-added automated, electric and digitalised offering; and strong order pipeline.

At the same time, Epiroc’s sustainability credentials were shown off for the world to see between October 1 and December 31.

In addition to the SBTi validation, over this period, the company laid out plans at its Capital Markets Day for its third battery-electric retrofit project, the Minetruck MT436B; secured its first order for Scooptram ST1030 battery conversion kits from Evolution Mining’s Red Lake gold operations in Canada (on top of the delivery of new ST14 Battery LHDs); extended its range of flexible charging products for battery-electric mining equipment; and announced a project with Boliden and ABB to develop a next-generation battery trolley setup for the Kristineberg mine in Sweden.

The only thing that was missing from this packed three-month period was the launch of a brand-new battery-electric machine, yet this will come. Epiroc has plans to electrify its full fleet of underground load and haul equipment by 2025 – including battery-electric retrofit solutions for its existing diesel fleet – alongside electrifying its surface fleet by 2030.

In line with SBTi requirements, Epiroc is committing to halve its absolute CO2 emissions in its own operations – so called Scope 1 and Scope 2 – by 2030, with 2019 as base year. However, more than 99% of Epiroc’s total CO2 emissions are other indirect emissions, with about 83% of the total coming from when customers use the products. It has, therefore, committed to halve the absolute CO2 emissions from use of sold products – so called Scope 3 – by 2030.

“This is industry leading and well above SBTi’s minimum requirements,” Epiroc said of the Scope 3 target. “The transition from diesel-powered to battery-electric machines will make a significant impact.”

Does this mean Epiroc will turn off the diesel-powered taps at a certain point, saying it will only supply electric equipment to customers?

Mattias Olsson, Senior VP of Corporate Communications, says no such action is planned, explaining that these Scope 3 targets align broadly with its mining customer base’s own CO2 emission cut goals. The majors all have plans to decarbonise their operations, with the most ambitious looking to hit net zero in 2030-2035. Codelco, for example, plans to electrify all its underground operations by 2030.

Demand for this equipment is bound to be high, which is where Epiroc’s retrofit program could become crucial.

Designed to allow miners an ‘entry point’ into cutting emissions underground through its in-demand midlife rebuild program, Olsson said supply of these machines could accelerate the industry’s electrification uptake and provide quicker access to zero emissions equipment compared with the long lead times that come with new battery-electric machines.

In a market that is becoming increasingly crowded, such an option may differentiate Epiroc from the rest of its peers, in the process, helping it achieve its ambitious goals to help keep global warming at a maximum 1.5° C.

Epiroc’s battery conversion offering comes to life with Evolution Mining Red Lake order

Environmental, Equipment maintenance, Mining equipment, Mining services, Power supply for mines, Precious metals, Sustainable mining, , , , , , , , ,

Epiroc is now offering customers conversion kits that, it says, “seamlessly transform” loaders from diesel-powered to battery-electric driven means, with the company having secured its first order for the solution from Evolution Mining’s Red Lake gold operations in Canada.

The new offering will speed up the mining industry’s shift to an emissions-free future, Epiroc said.

Battery conversions are already underway in Canada, with Epiroc’s Scooptram ST1030 loader being the first vehicle to undergo the transformation. Evolution Mining, earlier this year, ordered the conversion of two diesel-powered Scooptram ST1030 machines for use at Red Lake, in Ontario. In addition, it also ordered two new Scooptram ST14 Battery loaders and one Minetruck MT42 Battery to add to the fleet at Red Lake.

The company has been helped in this electrification pursuit by Ontario-based FVT Research, a Canada-based company with expertise in converting diesel-powered mining machines to battery-electric vehicles. Epiroc announced plans in September to acquire the company.

Kits to convert the Scooptram ST1030, one of Epiroc’s most popular loaders, are now available to order through most of Epiroc’s Customer Centers worldwide, the OEM said. Conversion kits for other machines will follow, including for the Scooptram ST14 loader, which is already being tested as a converted version.

Helena Hedblom, Epiroc’s President and CEO, said: “Converting existing diesel machines to battery electric will be a smart and cost-efficient alternative for mining companies that want to electrify their operations. It will be an important part as we together continue the drive toward emissions-free operations.”

The conversion involves removing the diesel engine, adding the battery and changing to an electric drive line. The end result is the same or higher performance level as diesel machines with all the added benefits of battery technology, which includes zero emissions and a healthier underground environment for operators, Epiroc said.

Epiroc’s service organisation will offer a quick turnaround time for the conversion, which is included in a midlife rebuild and puts machines back on site ready for heightened performance without unnecessary disruptions to production, it added.
