South32’s greenhouse gas emission (GHG) reduction plans were established early on in the company’s life, with a long-term goal of achieving net zero operational GHG emissions by 2050 set in motion within a year of it coming into being.

It has since established a medium-term target to halve its operational GHG emissions by 2035, from its 2021 financial year baseline, with several initiatives already in play to achieve this aim.

The company’s approach to climate change is focused on:

  • Reshaping its portfolio to the base metals deemed critical in the transition to a low-carbon world;
  • Decarbonising its operations, with a focus on the four operations within its portfolio which account for the majority (93%) of its emissions profile (Hillside Aluminium, Mozal Aluminium, Worsley Alumina and Illawarra Metallurgical Coal (IMC));
  • Understanding and responding to the potential physical impacts of climate change on its business to build operational resilience; and
  • Working with others to innovate and address shared challenges across industry, and to decarbonise the value chain.

The company has made headway on all four of these objectives since settling on this focus.

The portfolio reshaping is coming good with advancements in base metal projects and an acquisition of a significant stake in the Sierra Gorda operating mine in Chile.

In its 2023 financial year, the company commenced conversion of its first coal-fired boiler to natural gas as a transitional step at Worsley Alumina, with an estimated abatement of up to 205,000 t/y of CO2-e; converted 18% of pots at Hillside Aluminium to AP3XLE energy efficient technology and completed four of five EnPot trials; and commenced detailed design and execution planning for a commercial scale trial of CSIRO ventilation air methane mitigator technology at IMC.

And, when it comes to working with others to innovate and address shared challenges across industry, South32 can point to work it is carrying out under the auspices of the Electric Mine Consortium (EMC) – a group of companies aiming to accelerate progress towards a fully electrified, zero carbon, zero particulates mine.

As the lead in both the electrical infrastructure workstream, and energy supply and storage workstream within the consortium, South32 has agreed to take significant steps on behalf of the industry.

On the latter workstream, it recently scanned the market for long duration energy storage through an expression of interest, which received submissions from over 20 vendors, targeting seven members’ use cases.

“The knowledge gained informed a pre-concept study of thermal energy storage at Worsley Alumina and a related steam electrification study,” South32 said in its most recent Sustainable Development Report.

And, when it comes to the former, the company intends to build on its experience trialling the Cat R2900 XE diesel-electric loader at the Cannington operation in Queensland, with plans to trial three battery-electric light utility vehicles and a battery-electric integrated tool carrier, also at Cannington.

These trials, expected to run for at least 12 months and to prove the use case of electric vehicles for underground mining – including safety, reliability, range and capability requirements – will see three Bortana light utility vehicles deployed, two of which have been configured for heavy duties and one configured as a supervisory vehicle; with a Batt Mobile Equipment (BME) BIT120 integrated tool carrier also being put through its paces.

The Bortana EV is a battery-electric vehicle designed to handle the dynamic operating environment of underground mines. Designed and developed in Australia, it uses the chassis of a diesel-powered Agrale Marruá, electric technology from 3ME and Safescape’s design and engineering expertise. It is designed to tackle safety and health concerns by reducing emissions, heat and maintenance.

The BIT120, meanwhile, is BME’s second generation 20-t Integrated Tool Carrier, which combines an optimal production loader based on a Volvo L120F platform that has been converted to operate with zero diesel emissions, minimal noise, reduced vibrations and low heat output.

Charging infrastructure for all four pieces of equipment has already been installed at Cannington, and there are expectations the learnings from these trials will be factored into the plans at the Hermosa project in Arizona, USA – a project the company has already mooted could use battery-electric underground equipment.

Alongside this work, South32 continues to fund ongoing developments with BluVein1, a system that allows concurrent dynamic powering and charging of electric vehicles suited to the small-scale underground truck configurations, providing an alternative to static charging or fast charging technology.

Macmahon contemplates underground shift to battery-electric utility vehicles

One of Australia’s leading contract miners, Macmahon, says it is considering the use of the battery-electric Bortana EV model for its greater underground operations in the future.

The company made the admission after announcing the arrival of two Agrale Marruá AM200 light utility vehicles for its underground mining contracts (pictured). One of these – the dual cab version – is already in use and on site at BHP’s Leinster nickel operation in Western Australia.

Originally built for the Brazilian army, Macmahon has previously trialled these Tier 4 diesel engine utility vehicles, saying they are equipped to deal with what the underground mining environment throws at them.

“With the body, doors and tray all made from galvanised steel, along with a heavy-duty chassis, these corrosion-resistant vehicles are built to withstand the harsh underground environment,” it said.

Macmahon’s previous vehicles had a lifespan of 3-5 years, and it is expecting an operating life of up to six years minimum with Marrua, predicting these AM200s could last 8-10 years.

“This means, over time, we will have reduced maintenance and run cost due to the heavy-duty driveline components,” it said.

The company added: “Looking to the future, we’re also considering the electric Bortana EV model for our greater underground operations.”

The Bortana EV, which has a chassis of a diesel-powered Agrale Marruá, electric technology from 3ME and Safescape’s design and engineering expertise, has been trialled all over Australia. This includes a stint at Kirkland Lake Gold’s Fosterville mine, in Victoria; a test at Mincor’s Long nickel mine, in Western Australia; and a try-out at IGO’s Nova operation, also in Western Australia.

Following a four-month test at Kirkland Lake Gold’s Fosterville mine, in Victoria, Australia, last year, Safescape’s Bortana EV is starting to woo miners in Western Australia’s renowned Kambalda nickel district.

The Australia-based METS company, which manufactures and supplies safety products to the mining industry globally, took its battery-electric vehicle on a tour of Kambalda at the end of February and Safescape has already started receiving positive feedback.

A battery-electric vehicle designed to handle the aggressive operating environment of underground mines, the Bortana EV uses the chassis of a diesel-powered Agrale Marruá, electric technology from 3ME and Safescape’s design and engineering expertise.

The first stop on the tour was Mincor’s Long nickel mine. Mincor has a long history of nickel production in the prolific nickel belt and, with a lack of new nickel sulphide projects and prices projected by many to climb – in part due to the rise of lithium-ion batteries using nickel sulphate – the company is preparing to reinvigorate its Kambalda mines. These assets include the first greenfields discovery in the region for over 20 years – the high-grade Cassini project.

There are strong arguments for battery-electric equipment in underground mines that include improved health and safety outcomes (especially with no diesel emissions), efficiency gains and reduced maintenance and operating costs. While the deployment of this technology in mining is in its early stages, Mincor is not prepared to wait in the wings. Mincor’s Managing Director, David Southam, said as recently as October 2019, that the restart of its nickel mines in Western Australia would act as a “global showcase” for all-electric underground light vehicles when the mines reopen in the next few years, and Mincor, last month, became the first miner in Western Australia to host the Bortana EV.

Mincor COO, Dean Will, said: “Long is a large mine that is currently on care and maintenance, but with plans to be back in production as part of Mincor’s restart of nickel mining.

“We were able to define a course through the [mine] workings taking the vehicle from surface to 1,100 m underground via a range of road conditions including an area we were able to moisten down to create extremely slippery conditions that would challenge any four-wheel-drive vehicle.”

He added: “The performance of the vehicle generally, and in particular through the worse road conditions, far exceeded our expectations.

“The Bortana includes onboard 1,000 V charging capability, which was tested multiple times throughout the trial period. We also love the angle that the Bortana EV battery contains a high content of nickel and we are planning on utilising these vehicles underground to mine our high-grade nickel which is ultimately destined for the EV market.”

Martin Kime, COO of 3ME Technology, which supplies the batteries and electric drive train for the Bortana EV, was in attendance during the Long trials.

He said: “The opportunity to present the vehicle to several groups from leading mining and contracting companies over a short period in Kambalda was incredible. Because this technology is so new it is difficult to explain it without some physical reference point. Companies were able to experience the Bortana vehicle in realistic terrain and then ask questions about how we are able to deliver such smooth and efficient operation.

“3ME typically works directly with our OEM customers to create electric vehicles but it’s important that our team understand the application and, as such, we’ve all attended various underground and open-pit mine sites supporting Safescape. We find all of these mines want the same thing: safer, healthier mine environments with improved costs but without adding new risks or hazards to their operation.”

Safescape’s Managing Director, Steve Durkin, was also in attendance, saying one of the best parts of his job was visiting mine sites and seeing “experienced professional miners exposed to a piece of new technology that they want to understand but have reservations about”.

He explained: “The process of transformation over one or two hours driving in and snooping around the Bortana is awesome to watch. The entire team at Safescape get a kick out of this and we’re really looking forward to continuing the journey to familiarise more miners with EV technology.”

Safescape plans to begin production of the 5.7 t GVM Bortana EV in the September quarter of 2020 and grow with customer demand.

“Whether it is the Bortana, Tembo, Voltra or Kovatera, battery-electric light vehicles for mining is inevitable,” Durkin said. “The benefits are just too large. We will look to do our part and continue to wish our coopetitors around the world the best of luck. This is a big job and together we’ll put a dent in the DPM issue underground.”

Safescape, 3ME Technology and Agrale are celebrating the launch of the new Bortana electric vehicle (EV), with the partners now preparing to dispatch a prototype for a three-month trial at a gold mine.

The launch, taking place at Mt Cotton Training Centre on May 24, followed a successful exhibition at the Austmine conference, in Brisbane, Australia, Safescape said.

The project, partly funded by Australia’s METS Ignited industry growth centre, has seen the three companies design a purpose-built battery electric utility vehicle for the mining industry that, METS Ignited says, offers a significant increase in sustainability and durability compared with the existing options.

The Bortana EV uses the chassis of a diesel-powered Agrale Marruá, electric technology from 3ME and Safescape’s design and engineering expertise.

3ME Technology CEO, Justin Bain, said a vehicle of this nature is needed in the Australian mining landscape.

“Vehicles used in underground Australian mining operations have faced issues of corrosion, durability and emissions for a long time – there is a sore need for a better solution.

“The BORTANA EV was developed for the harsh environments of Australian mine sites and we’re really excited to see this vehicle in action. We have focused on achieving the highest levels of safety and compliance whilst delivering superior performance and efficiency.”

The application of battery-electric vehicles in underground mining provides several key benefits over traditional diesel-powered engines, with the new vehicle producing minimal heat, minimal noise and, most importantly, no diesel particulate matter exposure for workers within confined spaces. “This also means reduced costs in ventilation and maintenance for mine operators,” METS Ignited said.

Supporting the Bortana EV during the launch was the Agrale Marruá with both a single- and dual-cab vehicle on display. This vehicle is traditionally used in the Brazil army and mining industry, with Safescape selecting the chassis due to its corrosion-resistant body and ability to withstand the harshest of conditions.

The vehicles are future-proofed; equipped for integration with current autonomous and future artificial intelligence developments, according to METS Ignited, which provided A$500,000 ($343,700) for the project under its Collaborative Project Funds, in 2018.

Following the three-month trial at the gold mine – which Bain previously confirmed to IM was Kirkland Lake Gold’s Fosterville operation in Victoria, Australia – the prototype will have further exposure to other mining companies and contractors, METS Ignited said.

“The trial will test the battery-electric vehicle’s ability to achieve mining duty cycles and provide superior drivability, safety, corrosion protection, reliability and maintainability in comparison with the current underground diesel light vehicle fleet,” Bain said back in January. “The EV will initially be integrated into the Fosterville fleet as a supervisor vehicle and undertake all tasks required by the diesel light utility vehicles. An operational risk assessment of the BORTANA EV has been conducted with Fosterville to ensure the vehicle will meet its mine site compliance requirements.”

METS Ignited General Manager Industry Engagement, Peter Clarke, said: “We are pleased to support 3ME Technology and Safescape in developing a great solution for Australian mining operations. The safety benefits and cost savings achieved by implementing these vehicles onsite will make a significant difference for miners.

“This is a great example of how funding and support for collaboration pays off for the sector.”

Safescape Managing Director, Steve Durkin, thinks the Bortana EV will offer the right mix of capability and longevity in the mining environment.

The lack of tail-pipe emissions, plus reduced heat generation are just some of the benefits underground mines are likely to realise with the use of the Bortana EV, he said.

“We believe that the Bortana EV will have a lower total cost of ownership than any other comparable production vehicle in the mining environment,” Durkin concluded.
