LDO Group’s Rokion battery-electric light vehicle refocus starts to pay off

LDO Group is making serious headway in deploying Rokion’s ground-up-design electric light vehicles across Australia, with the New South Wales-based distributor hoping to have three machine trials in place before the end of the year.

LDO is focused on the underground mining and tunnelling industries, specialising in systems, processes, mine planning and training. It has been the exclusive distributor of Canada-made Rokion battery-powered vehicles in Australasia since 2018, having deployed vehicles across the soft- and hard-rock space.

The latest Rokion deployment LDO Group is celebrating is at Agnico Eagle Mines’ Fosterville gold operation in Victoria where a Rokion R400 was recently shown off alongside a Sandvik LH518B at a launch ceremony at the gold operation.

Alan Ross, General Manager of LDO Group, said the R400 vehicle – a platform able to accommodate three passengers in a utility vehicle setup or up to 12 in a passenger crew variant – has been deployed as part of a six-month trial at the operation.

“They (the Fosterville team) plan to use this in a people carrier configuration,” Ross told IM. “It will transport people to and from the operation.”

Considering the ramp-supported Fosterville operation goes below 800-m depth, this will present a good test for the R400’s re-generation capacity and uphill performance.

Rokion says the vehicle, which has 100 kWh of battery capacity, was engineered for the demands of underground mining and is its most adaptive platform design, capable of transporting a large crew in mine applications. Like all Rokion vehicles, it incorporates lithium iron phosphate battery chemistry, which, the company says, is the safest battery chemistry currently available.

The vehicle heading underground at Fosterville was previously deployed at a coal mining operation in Queensland, yet Ross says LDO Group is now re-focusing its efforts on the hard-rock mining space.

This has already seen the company partner with Newmont on an R400 deployment at its Tanami underground operation in the Northern Territory of Australia where it was initially used to transport team members up and down the mine.

Newmont said last year that early indicators had shown the vehicle had the capability to complete several trips to and from the bottom of the Tanami mine without requiring recharging.

Ross agreed with the Newmont assessment, explaining that the company was expected to re-deploy the same unit to the Tanami operation with an additional battery cooling module later this year.

“The ambient temperatures can reach 50°C in the Tanami desert, so we have equipped the vehicle with this new module to cope with such extremes,” he explained.

The company also has two R200 units – which include a four-passenger crew truck and a two-passenger utility truck – in Australia awaiting redeployment. One of these vehicles recently completed a successful stint at a tunnelling operation in the country.

LDO is also engaged with another mining company with an operation in New South Wales seeking to trial Rokion’s smallest battery-electric platform, the R100.

The R100 series includes a four-passenger crew truck and a two-passenger utility truck, with both models built on the same frame dimensions and available in ramp-ready configurations.

“We’re currently focused on these three key customers and supporting them in terms of the deployments and on-going operations,” Ross said.

In addition to regular site visits from LDO personnel to support maintenance and operations staff at the underground mines, LDO staff are able to remotely download data logs for these machines on a daily basis, assessing if there is potential for optimising the operation or if maintenance work may need to be conducted.

With many companies in the battery-electric light vehicle conversion space in Australia struggling to get hold of donor diesel vehicles, Ross says mining companies are increasingly appreciating Rokion’s ground-up approach.

“We have a fantastic OEM partner to rely on for these vehicles and we at LDO are able to support them in the best possible way,” he said. “We don’t have to rely on a different vendor to obtain the base machine; the design, engineering, manufacturing and testing are all performed under the Rokion roof, ensuring quality from concept to delivery.”

Ross said Rokion is continually working on design improvements and new machines based on industry feedback, with a newly-designed R200 vehicle set to bridge the gap between the existing R200 and the larger R400.

The latest in Rokion’s R200 Series is an 11-passenger crew truck built on a heavier frame and suspension construction than previous models, Kipp Sakundiak says

Kipp Sakundiak, CEO of Rokion, was happy to provide more details of this to IM: “The latest in our R200 Series is an 11-passenger crew truck built on a heavier frame and suspension construction than our previous models, all the while maintaining the simplicity and performance of dual drive motors.”

Sakundiak said the new model was robust and powerful, at the same time offering a comfortable ride for all crew members.

He added: “There is a lot of adaptability built into the new platform, including configurations for soft- and hard-rock applications. It’s one of our most versatile designs.”

Schlam delivers 1,500th Hercules dump body in Australia

Schlam has now reached the milestone of manufacturing its 1,500th Hercules dump body in Australia, with the dump body in question delivered to Glencore’s Mt Owen complex in the Hunter Valley of New South Wales.

Now in its 14th incarnation, the Schlam Hercules has become the dump body of choice for many of the most significant Tier 1 operators, OEM truck builders and mining contractors in Australia, Schlam says.

Schlam Chief Executive Officer, Matt Thomas, said it was a team effort to reach this milestone.

“Our manufacturing division – Schlam Payload Solutions – is filled with some of the most dedicated and hardworking individuals I’ve ever met. And, when they work together, anything is possible.

“The pandemic and supply chain concerns have pressured our team, however, they have managed these challenges superbly while maintaining our commitment to quality and customer service.”

The first Hercules was manufactured in Australia in 2003, and it took 17 years to reach the 1,000th milestone. It took the company just 22 months to then reach the 1,500th mark.

Thomas says that long-term national supply contracts with BHP, Fortescue, Glencore, Northern Star Resources, Newmont and other significant miners mean that the Hercules is set to continue along this upward growth path.

“We are creating efficiencies in our manufacturing processes through robotics, automation and ‘LEAN thinking’ to support this growth while maintaining quality,” he said.

“We’re also growing our sales and aftersales teams, ensuring that customer service is exceptional at every step of their experience with Schlam. We pride ourselves on following our products into the field and believe this has been a critical element in our growth.

“I thank the whole team – no matter where they work in the company – for helping us reach this milestone, and I look forward to many more to come.”

Newmont’s Gosteva urges action to achieve mining industry’s decarbonisation goals

Partnerships between miners and mining equipment, technology and service (METS) providers will prove key in solving the emissions reductions and sustainability targets mining companies have set for 2030 and beyond, Victoria Gosteva, Decarbonisation Program Manager at Newmont, said at the SME MineXchange Annual Conference & Expo in Salt Lake City today.

While outlining Newmont’s Energy & Decarbonization Program on stage, Gosteva made important statements about how the wider industry could decarbonise its operations and hit the goals it has set. Newmont, itself, has set a goal of reducing its greenhouse gas (GHG) emissions by more than 30% by 2030, with an ultimate goal of being net zero carbon by 2050.

Gosteva, urging actions over the near term, said partnerships with the METS community would be needed to set the companies on the right track to hit their sustainability goals, explaining that it was not only the technology-readiness element that needed to be addressed, but also the required infrastructure to, for example, charge electric vehicles.

“We can no longer afford to be fast followers as an industry,” she said. “There is really not that much time left to reach the 2030 targets.”

She said the investment community was also taking note of the need to decarbonise mine sites, with emissions likely to become a big contributor of company valuation metrics in the future.

Focusing on Newmont’s journey, in particular, she highlighted the $500 million the company committed over five years toward climate change initiatives back in 2020.

In addition to a number of PPA agreements looking to decarbonise the power grid of many of its remote mines, she also highlighted the 2021 signing of a strategic alliance with Caterpillar Inc to deliver a fully connected, automated, zero carbon emitting, end-to-end mining system, as well as a number of “energy efficiency” type of projects related to automation, data analytics and other projects that came under these initiatives.

Many of these projects were being helped by an enhanced investment system and process that incorporates and addresses emissions through an embedded carbon pricing mechanism. Gosteva said adding an emission calculator into these models where every project has an emission aspect in the investment review saw many of these projects develop a solid business case.

One project that has been helped by this is the strategic alliance with Caterpillar that will see the introduction of first-of-a-kind battery-electric haulage technology and automation at the gold miner’s Cripple Creek and Victor (CC&V) and Tanami mines in the USA and Australia, respectively.

Under the agreement, Newmont plans to provide a preliminary investment of $100 million as the companies set initial automation and electrification goals for surface and underground mining infrastructures and haulage fleets at Newmont’s CC&V mine in Colorado, USA, and Tanami mine in Northern Territory, Australia. The goals include:

  • Introduction of an automated haulage fleet of up to 16 vehicles at CC&V planned through 2023, with a transition to haulage fleet electrification and implementation of Caterpillar’s advanced electrification and infrastructure system with delivery of a test fleet in 2026. Actions include validating first-of-a-kind battery-electric haulage technology in the years prior to full production of autonomous electric haulage equipment;
  • Caterpillar will develop its first battery electric zero-emissions underground truck to be deployed at Tanami by 2026. The deployment includes a fleet of up to 10 battery-electric underground haul trucks, supported by Caterpillar’s advanced electrification and infrastructure system. This includes first-of-a-kind battery electric haulage technology for underground mining in 2024, the introduction of battery autonomous technology in 2025, with full deployment in 2026.

Gosteva highlighted that this project – which would also see the companies work on re-using batteries for energy storage when they hit their end of life in mobile mining applications – was very important to the company achieving its goals, but acknowledged that there was no silver bullet to achieving its targets.

ICMM looks to address mining industry approach to social performance with new tools

The International Council on Mining and Metals (ICMM) has published a set of practical tools to, it says, strengthen approaches to managing social performance within mining companies, to support more harmonious company-community relationships and enable positive socio-economic outcomes.

Social performance is the outcome of a company’s engagement, activities and commitments that directly and indirectly impact stakeholders, particularly the local communities that live close to mining operations. Good social performance requires companies to have robust management approaches and systems in place that avoid harm to people and planet, whilst contributing to social and economic development.

ICMM’s new tools have been designed to support companies to strengthen these capabilities, in order to build and maintain positive relationships with local communities and broader society.

Rohitesh Dhawan, CEO at ICMM, said: “Mining-related activity affects local communities and often takes place on Indigenous land. The industry has a critical role to play in creating lasting positive impact for those affected and can only achieve this through consistent approaches to social performance.

“This isn’t something that our industry has always got right, and we have seen the devastating impact it can have when it goes wrong. Just as financial and environmental risks are integrated across business decision making, these tools support companies to better integrate social risks and impacts to manage their social performance more effectively. ICMM’s social performance tools are available to the entire industry. They will support business leaders and social performance practitioners assess the maturity of social performance in their business, build competency, integrate social performance across the business and contribute to the organisational culture required to consistently avoid harm and deliver business and societal value.”

Tom Palmer, CEO of Newmont and Chair of ICMM’s CEO Social Performance Advisory Group, said: “Improving social performance will require leadership, commitment, tools and a willingness to be held to account for our impacts. I am reminded every day about the impacts our activities can have on people’s lives-our commitment to eliminating fatalities from our workplace is an example of where leadership, commitment and vigilance must exist for us to ensure our people go home safe every day.

“Improving social performance requires us to stand in the shoes of the community or those directly impacted by our activities-how do we like what we see when we look back at ourselves?”

The tools have been developed to support leaders, non-experts, and social practitioners as they work to better integrate social performance throughout their businesses. The individual tools include:

  • Accessible introduction to social performance, the value it delivers and how to achieve good performance;
  • A maturity matrix to establish where a company is on their social performance journey and guidance on developing an action plan;
  • A competency framework to help build the experience, skills and knowledge needed to manage social performance successfully;
  • Guidance on how to integrate community engagement across site-level activities;
  • Guidance on how to integrate social performance across the business as a whole; and
  • Support for leaders and decision-makers working to embed social performance into their operating model

These tools build on ICMM’s existing bank of guidance and resources on social performance.

Northern Star shores up KCGM energy supply with Newmont Kalgoorlie power deal

Newmont has agreed to sell its Kalgoorlie power business to Australia’s Northern Star Resources Ltd in a deal that could see the leading gold miner pocket $95 million of cash.

The deal follows the January 2020 sale of Newmont’s 50% stake in Kalgoorlie Consolidated Gold Mines (KCGM). Of the $95 million in cash, $25 million relates to an option payment previously received from Northern Star as part of this stake. The cost of the option will be deducted from the final purchase price, leaving Northern Star to pay the balance of $70 million at completion, expected to occur in December 2021.

Newmont said the Kalgoorlie power business has been a profitable asset for Newmont since the sale of its stake in KCGM. It supplies electricity to KCGM via a suite of contracts, licences, approvals and third-party arrangements, including a 50% interest in the 110 MW duel fuel gas turbine Parkeston Power Station near Kalgoorlie, owned in joint venture with Canadian energy utility, TransAlta Corp.

Northern Star said the purchase provided the company with significant synergies and value, including infrastructure and power security to support the requirements of KCGM; lower power costs at KCGM; further options for Northern Star to implement renewable energy.

Northern Star Managing Director, Stuart Tonkin, said: “The purchase means our Kalgoorlie power supply will now form part of our studies into ways to meet our commitment to becoming carbon-neutral.”

Newmont President and CEO, Tom Palmer, added: “Australia is a critical contributor to Newmont’s global portfolio of world-class assets, located in top-tier jurisdictions. With the sale of this non-core asset, we will continue our regional focus on delivering long-term value at our Boddington and Tanami operations and advancing our future project pipeline through active exploration campaigns.”

Gold industry ready to take action on cyanide use, DST’s Lemieux says

The move away from cyanide in gold processing has been talked of for many years, with words often not followed by actions, yet David Lemieux, President and CEO of Dundee Sustainable Technologies (DST), believes the industry is now starting to get serious about assessing alternative lixiviants.

His assertion comes on the back of one of the biggest gold miners in the world recently making such a move with the help of DST.

Back in December, Newmont signed a Technology Transfer Licensing Agreement with DST to use its cyanide-free gold extraction technology, known as the CLEVR Process™.

The CLEVR Process uses no cyanide, produces no toxic liquid or gaseous effluent and the solid residues are inert, stable and non-acid generating, according to the company. With fast leach kinetics of 1-2 hours, the ability to treat refractory ores and handle base metals, plus a competitive capital/operating expense, the solution has been gaining prominence in the gold market.

Having tested the process out on a variety of ores from various sources, DST is now in the commercialisation phase with CLEVR.

The pact with Newmont follows a successful test work program in the March quarter of this year, after which the gold miner expressed its interest in the execution of such an agreement. This led to Newmont conducting laboratory CLEVR leaching tests in its technical facilities in Englewood, Colorado.

As part of the agreement, DST and Newmont, agreed to:

  • A two-year, non-exclusive licence for the use of CLEVR at the laboratory scale in its Colorado technical facilities, with an option to renew for an additional two-year period under the same terms;
  • Technology implementation support by DST, including all technology laboratory protocols in addition to technical training sessions to initiate and support the technology transfer and practical operations;
  • Ongoing technology support, and for DST to review the laboratory test plans, execution and results conducted by Newmont; and
  • Any process scaling-up requirements resulting from positive applications of CLEVR will be conducted jointly with Newmont at DST’s technical facilities in Canada and/or on-site using DST’s technology and engineering group expertise.

Lemieux said the agreement should be viewed as an indication the gold industry is serious about assessing alternative processing approaches.

“DST’s CLEVR Process is a mature and developed novel gold processing technology that allows majors to properly assess how it can be implemented within a given project in terms of environmental benefits, operational efficiency, and operating and capital costs,” he told IM. “Such a level of detail then allows for properly integrated decision making.”

He said there had been increased interest over the years from the industry with regards to alternative processing approaches, which is likely to continue as more jurisdictions target cyanide operations and pressure operators to reduce their dependency on the lixiviant as the main and sole gold recovery mean.

CLEVR is one of two “novel metallurgical processes” DST has in its portfolio, the other being its GlassLock Process™.

GlassLock is a patented process for the sequestration and stabilisation of the arsenic often associated with copper, gold, silver or polymetallic deposits.

In DST’s approach, the arsenic is incorporated into a highly stable and insoluble glass form that can contain up to 20% arsenic, while meeting or exceeding the requirements of the USA EPA’s toxicity characterisation leaching procedure and the Synthetic Precipitation Leaching Procedure, the company said.

Also in the commercialisation phase, GlassLock has been operating at an industrial scale thanks to a demonstration facility built and operated by DST.

According to Lemieux, the increased number of complex orebodies currently being developed means there is likely to be more interest in both CLEVR and GlassLock.

“The chemistry and conditions of the CLEVR process can allow for improved gold recoveries,” he said. “This, combined with DST’s ability to efficiently and permanently stabilise arsenic using GlassLock, is providing good opportunities for DST.”

The Glasslock process, he said, is equally targeting existing operations that have immediate arsenic production and stabilisation needs as well as operations/miners required to address and stabilise legacy arsenical material as part of their permitting requirements.

These abilities were recently recognised by engineering firm Hatch, which entered into a Technology Framework Agreement with DST that could see GlassLock used in combination with Hatch’s fluid bed reactor and arsenic dry scrubbing technologies on gold and arsenopyrite projects.

The objective of the agreement was to “synergise” Hatch’s extensive client base, commercialisation and marketing expertise, fluid bed reactor and arsenic dry scrubbing technologies, and large-scale equipment engineering, supply, procurement, and life cycle services capabilities with DST’s innovative technology to identify and develop potential gold and arsenopyrite projects using GlassLock, the companies said.

While they cannot point to specific results of these two technologies complementing each other, Lemieux said DST has continued and is currently working on testing programs where the roasting and vitrification approach is applied on complex gold concentrates.

“These programs were generated and originate from DST’s own development efforts, but we hope to see more similar opportunities coming from Hatch in the future,” he said.

Lemieux concluded: “Implementing novel metallurgical processes within the industry takes time and DST has progressed greatly, and continues to do so, on the design and operating parameters of specific on-site implementations of GlassLock and/or CLEVR facilities.”

Newmont to drive mobile equipment decarbonisation plans forward with battery-electric power

Among the options for decarbonising mobile mining equipment, Newmont’s primary focus is on the use of battery-electric power, Dean Gehring, Executive Vice President and Chief Technology Officer, told the Energy and Mines Virtual World Congress today.

Gehring, after presenting ‘Toward Net Zero Mining: The Strategy Behind Our Climate Targets’, admitted that the biggest challenge the company faces in terms of decarbonising its operations is with diesel-powered mobile equipment.

“That is the largest area and probably the most challenging, technologically, to address,” he said. “Anything that is plugged into the grid, we have opportunities either through PPAs (power purchase agreements) to buy green energy or to potentially build wind or solar power. That (decarbonising mobile equipment) is an area, in particular, I think we will need a lot of support and partnership with vendors.”

He added: “We are not eliminating any opportunities (for haul truck mobility). We recognise it will take probably a multitude of different solutions to get there. Our primary focus is on battery-electric. We think that is probably going to be the best option going forward. But, like I said, this is a very dynamic space, so we are not eliminating any solutions.”

The company’s decarbonised mobile equipment solutions to date include the use of battery-electric equipment at the Borden underground gold mine in Ontario.

Gehring said the company is also considering the use of trolley assist haulage at the Penasquito operation in Mexico. Newmont already has Komatsu 930E electric drive haul trucks at the operation, with Gehring saying the introduction of overhead power lines on the most fuel intensive haulage routes, could lead to the Penasquito fleet saving up to $30 million and potentially reducing the company’s emissions by over 20,000 t/y of carbon.

The company has also mooted a potential battery-electric fleet at the underground Tanami Expansion 2 project in Australia.

While Gehring did acknowledge there were few “high production” examples of battery-electric trucks in mining operations across the globe, he did point to a potential secondary life for ‘spent’ batteries after use in haulage vehicles, saying he saw them being incorporated in battery storage projects on mine sites.

Newmont has plans to achieve a greater than 30% reduction in absolute greenhouse gas emissions and intensity by 2030 (Scope 1 and 2), which will be delivered from current operating assets through a shift to renewable energy, fuel switching, fleet electrification, and site energy efficiency improvements through its Full Potential program.

Austin Engineering, Melter celebrate new pact with Peñasquito truck bodies order

Austin Engineering has entered into an agreement with Mexico-based equipment manufacturer Melter to broaden its product delivery and service capabilities in the US and the northern region of South America.

This agreement has already delivered a significant new contract with a world-class miner, according to Austin, with Melter set to manufacture Austin-designed truck bodies for the initial supply of five lightweight Ultima bodies for Newmont’s Peñasquito gold operation in Mexico.

In addition to building truck bodies, Melter will also provide local support and maintenance assistance to Newmont, supported by Austin’s US-based teams in Casper, Wyoming.

“Newmont is the world’s largest gold miner and there is potential for further sales to this customer,” Austin said.

The Melter partnership is the latest iteration of Austin’s roll out of “hub-and-spoke” networks in the Americas to support Austin’s central US manufacturing hub in Casper.

Austin says it is establishing “spokes” closer to significant mining areas via new facilities or through partnerships and preferred supplier arrangements. The objective of this approach is to reduce the logistics cost and complexities of delivering truck bodies over large distances. As part of this strategy, in instances where transport costs are high, the Casper facility will provide designs and kits for local assembly to the end user facilities. This approach is intended to improve the competitiveness of Austin’s Casper facility and increase market share.

The hub-and-spoke initiative is part of an “advanced manufacturing strategy” being deployed by Austin following its strategic review of global operations completed in July, which identified several business optimisation and growth opportunities.

Austin’s Casper base has been further supported by the lease of a 23,000 sq.ft (2,137 sq.m) manufacturing site at Fort McMurray in Alberta from which Austin is able to better service its customers in the remote regions of western Canada though better product delivery logistics, shorter travel times, and local service and maintenance teams.

Austin CEO and Managing Director, David Singleton, said: “We are very pleased to have formed a partnership with Melter, which enables Austin to grow its service offering in a market where we don’t currently have manufacturing capabilities. Our partnership with Melter allows Austin to competitively deliver on its contract to supply Austin-designed truck bodies to Newmont’s Peñasquito operations and we look forward to growing our partnership in the future.

“We are continuing to review other potential spoke locations to support our Casper facility and delivering on our US strategy to improve our equipment delivery logistics and reduce overall transport costs, especially into remote areas, making our product offering more cost competitive.”

Melter Chief Executive Officer, Carlos Uribe, said: “We are pleased to develop our strong relationship with Austin Engineering, one of the leading OEMs in the global mining industry, as their regional supplier to build and support their truck bodies and other equipment on and off mine sites in Mexico including at Newmont.

“Over the last 30-plus years Melter has built a completely integrated manufacturing system for high-spec metal-mechanic components, as well as a highly committed and qualified 800 people strong team aimed at delivering the highest client satisfaction in the USMCA market; we are honoured to be able to use our capabilities to deliver Austin’s mining products both locally and potentially overseas.”

Newmont to continue use of K2fly’s RCubed Resource Governance Solution

K2fly Ltd has announced that Newmont has signed a five-year extension to its existing contract for K2fly’s Resource Governance Software as a Service (SaaS) solution.

The extension agreement has a total contract value (TCV) of A$1.3 million ($951,289) and builds on the initial three-year agreement signed in March 2020, which came with a TCV of A$900,000. The agreement will extend the contract period to March 2028.

Newmont will continue to use K2fly’s RCubed Resource Governance Solution across 12 operating mines as well as joint ventures and projects across global operations as part of the agreement, K2fly says.

RCubed software, K2fly says, generates resource and reserve reports that support reporting codes such as JORC, NI-43-101 and SAMREC across the major stock exchanges – including NYSE, LSE, TSX, ASX and JSE. It assists mining and resource companies in complying with their regulatory reporting obligations.

Nic Pollock, Chief Executive Officer of K2fly, said: “This extension of our original agreement from March 2020 with the world’s leading gold company reaffirms the importance of K2fly’s solutions in helping large resources organisations with their ESG reporting and aligns with Newmont’s purpose to create value and improve lives through sustainable and responsible mining.”

MEDATech launches profit, emissions forecasting software for fleet electrification

Ontario-based MEDATech has launched what it says is the “Deswik of underground fleet electric vehicle electrification” with its Electric Vehicle Fleet Optimization Software (EV-FOS).

Built in MATLAB, MEDATech’s tool for simulation, data acquisition and industrial software development, EV-FOS approaches battery-electric vehicle (BEV) optimisation in mines from the practical (vehicle) side. Its goal is to ensure that the transition to electrification is profitable as well as good for the environment, MEDATech says.

The launch of the software, just in time for MINExpo 2021, in Las Vegas, comes after four years of development in collaboration with McMaster University’s Bauman Lab for Electrified Powertrain Research.

The software is, the company says, essential to building a mine electrification plan that is both optimal and practical, based on technology that is available today.

The Collingwood, Canada heavy-equipment design/build engineering company has trialled EV-FOS with major miners like Glencore, Newmont and Torex Gold, with the software conclusively proven to reduce CO2 emissions and help save cost, according to the company.

“EV-FOS is very precise,” MEDATech President, Rob Rennie, says. “The alternative to using our software is developing your own calculations or guessing. With millions or tens of millions of dollars hanging in the balance, it makes sense to invest in something that yields accurate forecasts.”

MEDATech EV-FOS optimises BEV energy usage for new and existing mines, and is as useful for mine development as it is for production. The software can compare BEV fleets versus diesel fleets in terms of life-of-mine vehicle costs, CO2 emissions, fuel and ventilation costs, as well as vehicle maintenance. It also shows the difference in cost and production values between fast charging, battery swapping and on-board charging.

EV-FOS also calculates optimal BEV type, battery size and charging infrastructure for any given mine. It shows effectiveness in dollars per tonne by the level, by the year, for fast charging, for battery swapping and for diesel, MEDATech says.

“Measuring cost in dollars per tonne and in total CO2 reduction are the big dividends,” Rennie says. “That includes labour, capital costs, operation costs and ventilation costs for mines designed for electric operations. It compares these figures to operational and ventilation costs for mines designed only around diesel power, for an equivalent production requirement.”
