Ampcontrol strengthens decarbonisation drive by joining the Electric Mine Consortium

Ampcontrol says it has joined the Australia-based Electric Mine Consortium (EMC) to drive efforts towards electrifying and decarbonising the mining industry.

The EMC is a growing group of highly regarded mining and service companies, driven by the imperative to produce zero-emission products for their customers and meet mounting investor expectations and industry challenges.

Ampcontrol is strengthening its strategic focus on decarbonisation through the innovation and development of electrical solutions, adapting to the changing times.

“Joining the Electric Mine Consortium is a natural progression of our commitment to supporting our customers and industry through the national energy transition,” Rod Henderson, Ampcontrol Managing Director and CEO, said. “Ampcontrol is at the forefront of renewable energy manufacturing. We engineer and supply advanced technology, products, and services to enable a competitive advantage in a net-zero carbon environment.”

EMC Founder and Director Graeme Stanway, said: “The way we generate, store and harness energy around the globe is undergoing a period of major change.

“A global ecosystem has begun to emerge to underpin the innovation and scaling of electrification technologies.”

As well as pioneering products in the renewable energy space, Ampcontrol has been using its engineering expertise to already assist with the transitioning mining industry.

Alongside Tritium, Ampcontrol was a winner in the global ‘Charge On Innovation Challenge’ in May 2022. The joint submission was an end-to-end mining haul truck battery swap solution that is fully automated, relocatable, scalable and cell agnostic. In a drive-in/drive-out recharging station, an autonomous transfer robot swaps batteries in 90 seconds, significantly reducing safety risks and increasing productivity by excluding personnel from the swaps process.

Henderson said: “One of the areas Ampcontrol identified as a need of the industry was assisting businesses with the next steps to get to the future state of electrified mining operations. When businesses think ‘I need energy’ to perform certain functions, the first instinct is often to acquire more energy. Our expertise at Ampcontrol is to help businesses use the materials they already have available, in a different way.”

Ampcontrol says it recognises the importance of partnerships and collaboration in developing technology solutions to enable a competitive advantage in a net-zero carbon environment.

“It is important to demonstrate we work alongside other businesses to contribute to the low carbon economy transition and to the responsible sourcing of prime materials to enable a competitive advantage in a net-zero carbon environment,” Henderson said.

The EMC has launched a call out to companies in the tech, renewable and manufacturing industries that can provide 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.

Ampcontrol joins over 20 miners and suppliers to the sector that includes Newcrest, South32, Barminco and Epiroc to create the EMC with the ambition to accelerate progress towards the fully electrified zero CO2 and zero particulates mine.

Barminco extends relationship with Evolution Mining at Cowal gold mine

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.

Redpath awarded underground mining services agreement at MMG’s Dugald River mine

Redpath Australia says it has been awarded a new underground mining services contract at MMG Limited’s Dugald River mine in northwest Queensland.

Dugald River is one of the world’s top 10 zinc producers, located some 65 km northwest of Cloncurry. It produced 41,655 t of zinc concentrate and 4,740 t of lead concentrate in the June quarter.

The contract involves all underground development activities and will require up to 200 personnel in various management, operational and trades roles, with mobilisation commencing in the coming months, Redpath said.

Back in September 2020, Barminco agreed the terms of a variation and extension to its development and production contract at Dugald River, with the variation extending the term of the contract by 18 months to December 31, 2022.

Zero Automotive overcoming barriers with BEV conversion offering

Zero Automotive is one of several Australia-based companies looking to supply the clean and green light utility vehicles the domestic hard-rock sector requires over the next decades to achieve crucial sustainability goals while retaining high productivity levels.

Thanks to the support of a significant copper-gold miner in Australia, its membership of the Electric Mine Consortium (EMC) and METS Ignited backing, the company finds itself in a strong position to deliver these machines against a backdrop of supply chain issues and ever-evolving safety and regulatory requirements.

“We’ve got commitments for six machines altogether and are in the process of offering our production version to the market,” Dan Taylor, Business Development Manager for Zero Automotive, says.

The first and second units are already running at OZ Minerals’ Carrapateena copper-gold mine in South Australia – Zero Automotive’s home state.

The first machine – a ZED70 Ti™ battery-electric light vehicle – was originally delivered to the mine at the back end of 2020 for testing. After successful trials, the company acquired this unit outright and, in early-2022, added a second Zero Automotive ZED70 Ti to enable its workforce to familiarise themselves with the capabilities and charging methodology that come with electric light utility vehicles.

Since then, the company has delivered a third ZED70 Ti conversion to Barminco, which is now on site at its client IGO Ltd’s Nova nickel-copper-cobalt operation in Western Australia. This vehicle is the first single cab conversion developed by Zero Automotive and will be deployed to site foremen to allow the mining contractor to gain a good understanding of its capabilities.

All three of these machines – and the three to follow – are based off battery-electric conversions of the Toyota LandCruiser 79 Series, a vehicle that has been part of the Australian mining landscape for many years.

The modular nature of the Zero Automotive platform enables its long-life battery energy system to be reused in multiple chassis, lowering the total lifecycle cost of the fleet as well as the cost of Scope 1 emissions, according to the company.

They also include dual AC-DC charging with the CCS Combo2 connection, which is becoming increasingly standardised in the mining space.

Data and feedback from the second OZ Minerals machine and the initial Barminco vehicle will be fed back into the EMC ecosystem under the Light and Auxiliary Equipment Working Group as part of the consortium’s continual improvement and knowledge sharing remit.

The EMC said of the consortium’s ongoing light and auxiliary equipment electrification ambitions: “Converting light and auxiliary vehicles as rapidly as possible to electric is key to the industry building the broader understanding and familiarity with electric equipment and infrastructure that will accelerate adoption across all aspects of operations.”

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

The following three machines are also expected to be deployed to EMC members, with METS Ignited agreeing to provide some A$400,000 ($297,938) of funding towards the diesel-to-battery conversion projects outside of the vehicles already delivered to OZ Minerals.

“The key thing with all of these vehicle deployments is the ZED70 Ti being able to do the job the miners need to perform safely and reliably, getting the associated charging infrastructure right and working with key stakeholders on the change management process,” Dave Mitchell, founder and CEO of Zero Automotive, says. “Operators also need to get used to the power under the hood and how to maximise the battery re-charging capabilities when going down ramp.

“As a matter of course, we train up and educate the sites about the best way to utilise these vehicles,” he said.

To this point, the two prototype vehicles already operating out at Carrapateena have shown that they can work for a typical shift without requiring a re-charge and can then utilise the battery’s AC/DC-DC fast-charge option during shift changeover to enable another user to run the machine for the following shift.

The use of LTO (Lithium Titanate Oxide) battery chemistry and a 60-kWh battery capacity has been behind this performance. This electric motor can generate continuous power of 75 kW and peak power of 134 kW, plus 358 Nm of continuous torque. These values will be increased to 100 kW, 200 kW and 520 Nm (1,200 Nm peak) for the production version.

To this point, the power dimension has often been the main metric quoted with any battery-electric machine, but Taylor pointed out that safety and regulatory considerations were often the biggest barriers to overcome in terms of getting machines operating at underground mines – a hurdle that Zero Automotive has cleared.

“We were able to successfully commission our second ZED70 Ti for OZ Minerals within two days of the machine arriving on site,” he said. “A lot of people are putting out offerings for light utility vehicles, but the required risk analysis in terms of deploying a vehicle underground has not been successfully worked through. This is rightfully a high bar to clear.

“We address any safety or regulatory considerations during our design process – not when the machine is on site – to make sure that operators can start using them quickly.”

Mitchell adds: “The user case is what we are focused on. That has allowed us to scale our offering quickly and ensure our clients can start running the machine underground as soon as they have it on site.”

Zero Automotive is expecting to deploy the other three machines on its books to the same companies (OZ Minerals and Barminco), but the final two machines of the six to be delivered will be under a revised platform to the original ZED70 Ti.

“It will be a platform that is designed from the ground up that incorporates the desired features and learnings from the first conversions, but we will simplify it to reduce complexity, weight and cost,” Mitchell said. “We’re sticking with the same battery configuration – which has proven itself in terms of power, safety and longevity – but we’re adding some auxiliary power outputs and ensuring the machine is multi-purpose.”

The latter element is tied to the company’s medium-to-long-term ambitions, which include the potential to supply battery-electric machines specific to the extended range space too.

For now, Zero Automotive is focused on getting its machines underground at hard-rock operations, ensuring operators and mining companies start realising the productivity and emission benefits that come with these zero-emission conversions.

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.

Polymathian, SimGenics, Simulation Engineering Technologies, MathWorks, First Mode to tackle electric mine simulation tasks

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.

Hindustan Zinc accelerates growth plans as it partners with industry leaders

Hindustan Zinc Ltd (HZL), a Vedanta Group Company and the world’s second largest integrated producer of zinc and lead, is in acceleration mode, embarking on aggressive expansion and collaboration plans with technology and innovation partners from across the globe.

One of the first mining companies to commit to going “Net Zero” by 2050, it has a strong focus on ESG reinforced by plans to deploy battery-electric vehicles, tap into more solar and wind power potential and recycle waste heat from its captive power plants. Such ambitions are being delivered with up to $1 billion of finance in the next five years to “go green” and, by 2025, achieve focused sustainability goals.

At the same time as it is looking to become an ESG leader, it is boosting its mine and metal production by leveraging “smart mining” and an extensive resource and reserve base.

IM put some questions to Arun Misra, Hindustan Zinc CEO, to find out how the company intends to deliver on its lofty ambitions.

IM: HZL’s 2021 financial year to March 31, 2021, was characterised by record production volumes and profitability; how were you able to achieve such results given the COVID-19-affected constraints on your operations?

AM: The uncertainty has evolved continuously. If I give you an example, we started the year with the uncertainty of COVID only; that is people getting infected leading to absenteeism. It was so contagious, it spread so fast, half of our workforce were down. So, that struck us heavily, but, nevertheless, because we had experience of last year, and this time there was no lockdown of industry, we were able to figure out how to manage and we did manage well, compared to last year’s same quarter, which was also COVID-affected. We had introduced various measures to change the way of working to ensure a safer working environment for the employees. We also got our workforce vaccinated along with their families to further minimise the risks associated with the pandemic.

Hindustan Zinc CEO, Arun Misra, says Hindustan Zinc has been at the forefront of ensuring personal health, be it of its employees or local communities

Furthermore, the automation and digitalisation efforts at Hindustan Zinc are equipped to better withstand these testing times while ensuring quick revival to a normal level of operations.

IM: During the height of the pandemic, HZL – like other socially responsible mining companies – supported communities within or close by to its operations. Can you highlight some of the actions you took over this period and what impact they had?

AM: We at Hindustan Zinc have been at the forefront of ensuring personal health, be it of our employees or local communities. We have gone beyond and extended our support to the state of Rajasthan and the nation at large by contributing significantly to the PM Cares Fund and Rajasthan Chief Minister Relief Fund.

To meet the requirement of oxygen during the second wave of the pandemic, we had set up an oxygen bottling plant at our Dariba unit (Rajsamand district) in a record time of five days and had supplied over 14,000 cylinders of medical oxygen. We even arranged 500 oxygen concentrators to be imported and distributed for use across the state.

We had provided an insulated vaccine van to the Udaipur district medical health office to support a smooth vaccination drive and extended support to the local health administrations, by disinfecting villages by spraying and fumigating with sodium hypochlorite solution and providing medical gear like masks, sanitisers and PPE to local communities.

We even constructed an 8,000 sq.m air-conditioning dome hospital, based on German technology, which has a capacity of 100 beds – including 20 ICU beds – to accommodate patients and provide them with essential COVID treatment and medical facilities.

IM: ESG is obviously a major focus area for HZL, as these examples illustrate. Where specifically are you investing in your mining, power and smelting operations to make them more environmentally friendly?

AM: As a COP26 business leader, we have always been active in tackling the repercussions of climate change and have a strong focus on reducing carbon emissions. We are pioneers in India, declaring our ambition to convert all our mining equipment to battery-operated electric vehicles and will invest $1 billion over the next five years to make our mining operations environmentally friendly.

We are continuously expanding our renewable power of 274 MW of wind and 40 MW of solar under our greenhouse gas reduction goals by converting 50% of our total power to renewable forms in the next five years. We are among the only two metal and mining companies globally – and among four Indian companies – to be part of the coveted CDP (Carbon Disclosure Project) ‘A List’ 2020.

Furthermore, we have even published our first Task Force on Climate-related Financial Disclosure (TCFD) Report this year and have also joined the Taskforce on Nature-related Financial Disclosures (TNFD) forum to understand nature-related risks and opportunities and accelerate the transition towards a nature-positive and carbon-neutral future.

We have set Sustainability Development Goals to 2025 for ourselves where we are aiming towards sustainable operations for a greener tomorrow.

Hindustan Zinc has embarked on a major growth push at its mining operations with six ongoing expansion projects that will see over 100 km of tunnels developed for underground infrastructure and ore access

IM: At the same time as this, HZL has embarked on a major growth push at your mining operations with six ongoing expansion projects that will see over 100 km of tunnels developed for underground infrastructure and ore access. How are you able to balance your sustainable expansion plans with pledges to reduce your overall footprint?

AM: We strive for operational excellence and cost efficiencies and continue to stay on the growth track while being equally cognisant of our environmental, social and governance commitments, as well as our sustainability goals. We are leveraging more digitalisation and automation than we ever have, as well as engaging with technology leaders to do ‘more with less’.

The SmartDrive equipment we plan to use enables higher productivity, lower operating costs and, most importantly, zero local emissions, featuring in-built energy recuperation technology to make the most of regenerative braking energy during downhill driving and deceleration.

Being a power-intensive business, our key focus is always on reducing dependence on non-renewable sources of energy and enhancing our renewable power base.

IM: How important has it been to partner with like-minded technology and solution providers to ensure you meet these ambitious goals? Can you provide some examples here?

AM: We always look for partners who align with our philosophy of running sustainable operations to achieve company goals. We don’t need one-off solutions from companies to meet our targets; we need companies that will engage throughout our medium- and long-term projects and provide an element of customisation that factors in the realities of operating in our underground mines. We look for global partners to work with us where we exchange ideas, insights and knowledge with them in our growth journey.

We believe in providing opportunities to our business partners to leverage collaboration on technology, innovation and digitalisation, for long-term value creation and mutual growth.

To support our expansion plan, it is crucial for Hindustan Zinc to collaborate with mine development and operation partners who share a similar vision to ours, which is to leverage cutting-edge technology to create a positive impact on the entire mining fraternity. We are currently working with companies like Sandvik, Epiroc, Normet, Barminco, RCT, Siemens, etc as our global partners. We have engaged with them to provide end-to-end solutions rather than sourcing a specific supply or service.

Hindustan Zinc has given an equal platform for women engineers in its mining operations, appointing India’s first female underground mine manager in 2021

IM: You have already stated a goal of 1.5 Mt/y of zinc production in the upcoming years and extending your lead as India’s largest integrated zinc-lead producer; what is your vision for the company to 2030 and beyond?

AM: We are excited about our next phase of expansion to take mining capacity from 1.2 Mt per annum to 1.35 Mt/a. We will surely cross 1 Mt and we should be above our guidance if we achieve the desired run rates in our third and fourth quarters.

While our growth plans are a key part of the company’s future, we are also focused on becoming the leading zinc-lead-silver producer from an environmental, social and governance point of view. Our DJSI Ranking of being among the Top 5 companies in the metal and mining sector is testament to this. We are already winning significant awards for our ESG and CSR efforts, and expect this recognition to continue and grow as we head towards mapping out our 2025 sustainability goals.

Also, the mining value chain is changing across the globe and more consumers are becoming aware of the origins of the products they buy and the emissions that come with their production.

Barminco, Newtrax, Sandvik team up to tackle pedestrian safety in underground mines

Perenti’s Barminco, Newtrax and Sandvik are partnering to develop what they say is a new technology-led solution that improves the safety of pedestrians working near heavy vehicles (HVs) underground.

Between 2008 and 2018, there were 12 fatalities involving HVs in the underground mining industry in Western Australia. Seven of those deaths were pedestrians.

“This statistic is a reminder that these mining machines – that weigh a minimum of 4.5 t and operate in areas of poor visibility – are a significant risk factor for people who work in close proximity to them in an underground environment,” the companies said.

A leading underground mining contractors, Barminco currently operates 25 projects in seven countries and employs more than 5,600 people. Almost all these employees will be exposed to a working HV during their career. In fact, every hour of every day of the year, there are approximately 2,000 Barminco employees working underground interacting with heavy vehicles.

Barminco’s scale and underground mining expertise, combined with Newtrax’s capability to develop collision avoidance systems and the high penetration of Sandvik HVs featuring advanced controls, means this partnership is uniquely positioned to understand how people and equipment interact in underground mines, they said.

Newtrax has developed a collision avoidance system that links “intelligent” cap lamps to the warning system inside the cab of an underground HV. The system provides the vehicle operator with virtual visibility of any pedestrians in the immediate area of their vehicle, along with an escalated warning system to both the pedestrian and operator as the distance between them reduces. This escalation transitions from warning to vehicle intervention, where the HV automatically reduces speed and comes to a controlled stop, when the system senses any pedestrian wearing an intelligent cap lamp in the high-risk zone.

Under the partnership, Newtrax will deploy its next-generation Level 9 Collision Avoidance System across Barminco’s Sandvik fleet, including the supply of intelligent cap lamps with advanced electronic safety features to Barminco’s underground mines. The technology is due to undergo initial testing at one of Barminco’s underground sites in January 2022.

Paul Muller, Perenti Chief Executive Officer, Mining, said the focus of the project was twofold – the safety of its people and the sustainable adoption of the technology industry-wide.

“The exposure of pedestrians to heavy vehicles underground is a significant risk not just for us, but for everyone involved in the underground mining industry,” Muller said. “The combination of Newtrax’s technology, our underground operating experience and Sandvik’s role in supplying heavy mining vehicles can put us in a position to offer the entire industry a smart solution to a complex problem.”

Simon Waghorn, Newtrax Regional Vice President – APAC, said the collaboration with Barminco would provide the partners with real-world experience that would help optimise the system as it develops.

“Although the Newtrax Collision Avoidance System is the best available system on the market, many more enhancements are required to accelerate adoption,” he said. “This partnership with Barminco, a world-class underground hard-rock mining contractor, will enable collaborative product development which will result in an even better product for the industry.”

Wayne Scrivens, Vice President – Sales Area APAC, Sandvik Mining and Rock Solutions, added: “Barminco is a very important customer for Sandvik and we are pleased to take on the challenge to develop and deliver the industry-leading intervention controllers, to enable slow-to-stop control of the equipment in Barminco’s fleet.”

Perenti’s Barminco seals Savannah nickel project contract

Perenti Global’s hard-rock underground mining subsidiary, Barminco, has finalised a contract with Panoramic Resources for development and production works at the Savannah nickel project in the Kimberley region of Western Australia.

The finalised contract represents a value of around A$280 million ($208 million) over a four-year contract term, Perenti said.

Under the terms of the initial letter of intent, announced on the April 6, 2021, Barminco commenced mobilisation and early mining works ahead of the schedule. With finalisation of the contract, Barminco expects development and production works will ramp-up over the coming six months to achieve full run rate of revenue early in the March quarter of 2022.

The contract will be serviced by new underground mining equipment including the use of tele-remote mining equipment, expected to deliver both safety and productivity benefits, Panoramic said.

Ore processing at Savannah is scheduled to begin in November with first concentrate shipment from Savannah targeted for the following month, Panoramic said. The building of an ore stockpile on the surface has already commenced and the company plans for this to reach 100,000 t prior to turning on the processing plant.

Perenti’s Managing Director and CEO, Mark Norwell, said: “We look forward to working together with the team at Panoramic to develop what we all expect will be Australia’s next long-life nickel producing mine. Despite the challenging labour market conditions in Western Australia, we have been successful in mobilising a labour force of approximately 110 highly skilled underground employees. We expect this to increase to 170 as the project ramps up. Securing this labour force has enabled us to commence early works ahead of schedule.”

Savannah has outlined a 12-year mine life with an average annual production target of 9,072 t of nickel, 4,683 t of copper and 676 t cobalt in concentrate. The mine is set to operate at average site all-in costs of A$6.36/lb of payable nickel, net of copper and cobalt by-product credits and royalty payments.
