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.

First of its kind Net Zero Standard devised for diversified mining sector

Environmental, Mining services, Sustainable mining, , , , , , , , ,

Climate Action 100+, which calls itself the world’s largest investor engagement initiative on climate change, has released a first of its kind “Net Zero Standard” for diversified mining companies such as Anglo American, BHP, Glencore, Rio Tinto, South32, Teck Resources and Vale.

The new standard aims to help investors assess the progress of diversified mining companies as they move towards net zero, providing them with robust tools to independently and consistently assess these companies’ transition plans, in order to understand their transition risk and support their engagement efforts.

Designed to complement the sector-neutral Climate Action 100+ Net Zero Company Benchmark, the standard will provide a transparent, systematic and evidence-backed engagement tool, giving Climate Action 100+ signatories and the wider investor landscape the metrics most specific to this important, but complex, sector, the organisation says.

“The Net Zero Standard for Diversified Mining reflects the outcome of extensive consultation with investors, mining companies themselves and other key stakeholders,” it said, adding that a final consultation on a draft of the standard was conducted in the June quarter before the final release.

As part of this development, the organisation has devised a set of metrics that diversified mining companies engaged with under Climate Action 100+ will be assessed against, and the scoring methodology that will be used. These metrics are additional to the Climate Action 100+ Net Zero Company Benchmark.

Additionally, a document called Investor Expectations for Diversified Mining has been published that, the organisation says, fleshes out the standard with background and rationale behind the metrics found in the standard itself.

The metrics laid out in both documents will now be piloted by assessing selected miners with the objective of testing their practicality. Feedback from these pilots will be used to further refine the metrics into a final list, with which it is expected public assessments will be made. These assessment results (as well as the narrative and context provided in the Investor Expectations) will bring impactful insights to engagement conversations, the organisation says.

The list of Climate Action 100+ companies that will be assessed with the standard include Anglo American, ANTAM, BHP, Glencore, Grupo México, Rio Tinto, South32, Teck Resources, Vale, Vedanta.

Rebecca Mikula-Wright, Chief Executive Officer, Investor Group on Climate Change, says: “The world’s leading miners are already shifting their businesses to help the world decarbonise, but some are just making claims that aren’t backed by reality. This new standard will help investors and governments separate the greenwashers from the companies that will have sustainable businesses in a net zero world.”

Laura Hillis, Church of England Pensions Board, added: “Investors often have exposure not only to the mining sector, but to many other sectors that are underpinned and enabled by mining. For example, the autos, property, steel and manufacturing sectors are highly dependent on the commodities produced by miners. By focusing on the strategic role of mining in the net zero transition, we can boost the resilience of our overall portfolio. This standard provides an ambitious but credible framework for investors and mining companies to ensure this critical sector supports a just and orderly transition to net-zero, and it raises the bar at a crucial time in this essential global economic transformation.”

DMC Mining Services says it has added a Boart Longyear LF™160 surface coring drill rig to its equipment arsenal at the Sierra Gorda copper-molybdenum mine in Chile, adding to the four pieces of equipment it already has on site.

The LF™160 is a surface diamond exploration rig with up to 1,800 m of NQ capability. This tool enhances safety and increases productivity by allowing 100% hands-free drilling when operating in conjunction with the FL262 FREEDOM™ rod handler, and is also CE Certified, DMC says. It is equipped with an inner tube that will allow drillers to retrieve a full 6-m inner tube out of the rod string using the wireline winch, according to FLSmidth.

DMC’s contract at Sierra Gorda, owned 55% by KGHM 55% and 45% by South32, was one of five new agreements it was awarded at the end of 2019. It is also carrying out work at KGHM’s Franke mine, in the Antofagasta region of Chile.

The Electric Mine Consortium and EPCA to run Cat 777 electric truck trial

The Electric Mine Consortium is looking to bridge the gap between the testing of electrified ultra-class haul trucks and continued rollout across industry of battery-electric underground trucks with a project to develop and trial a retrofitted 100-ton (91 t) haul truck as part of its consortium work in Australia.

It has teamed up with Electric Power Conversions Australia (EPCA), an Indigenous electric battery conversion company in Australia, to run a Caterpillar 777 haul truck electric vehicle demonstrator project.

The consortium explained: “The Electric Mine Consortium are focused across all fleet sizes when it comes to electrification. In our recent work, we have uncovered that in the area of larger surface in-pit trucks, there are some trials underway, however there is a lack of focus on the smaller trucks. Making sure we understand and trial electric technologies in smaller fleets is important to our members, and we were recently presented with an opportunity to do so by Electric Power Conversions Australia, an Indigenous electric battery conversion company in Australia.”

The conversion of the vehicle – one of the most commonly used surface trucks across the Tier 2 and Tier 3 mining company market, according to the consortium – will see the 750 kW diesel motor switched out with a 1,000 kW electric motor and 2 MWh of batteries, according to Clayton Franklin, founder and CEO of EPCA.

Franklin said he was expecting this configuration to allow for an eight-hour average run time, providing 30% more power than the diesel equivalent and the ability to move material quicker. He also predicted a 50% reduction in total cost of ownership on the battery-converted truck when compared with the diesel truck.

EPCA was founded in 2021 with the vision of providing a practical solution to the growing environmental impact of the Australian mining industry. Franklin himself was the lead engineer on a 220-t hydrogen-battery hybrid mining truck and also for an Epiroc D65 drill rig that was electrified.

The Electric Mine Consortium is a growing group of leading mining and service companies. These companies are driven by the imperative to accelerate progress towards the fully electrified zero CO2 and zero particulates mine. Mining companies Gold Fields, South32, OZ Minerals, IGO Ltd, Evolution Mining, Iluka Resources, MMG and Sandfire Resources are among the participants.

In the short time since the establishment, the consortium’s membership has grown almost two-fold, with over 40 ongoing equipment trials in 15 different locations having been mobilised.

South32 has now broken ground on one of two exploration shafts at the Hermosa project in southern Arizona, USA, in a sign of major progress at the base and battery metal project.

This milestone achievement commemorates the initial surface excavation that will be continued by Redpath USA to a planned depth of 900 m, the contractor stated in a LinkedIn post. Redpath and South32 signed a “limited notice to proceed” for shaft engineering and design at Hermosa last year.

Redpath said in this latest post: “The shafts will enable underground access for continued exploration of a world-class deposit containing the US critical mineral zinc as well as lead and silver – minerals needed for supporting electrification and renewable energy.”

In South32’s March quarter results, the company said it invested $176 million over the last nine months as it continued critical path activity and study work for the Taylor zinc-lead-silver deposit and the Clark battery-grade manganese-zinc-silver deposit. It also directed $12 million to capitalised exploration in the nine months ended March 2023 as it continued exploration programs at Taylor and Clark and the copper-lead-zinc-silver Peake prospect 8.

Just last month, the Hermosa project was confirmed by the United States Federal Permitting Improvement Steering Council, an independent federal agency, as the first mining project added to the FAST-41 process, which is focused on supporting informed decision-making while reducing and eliminating unnecessary and costly delays associated with projects.

South32’s Cannington Mine, in Queensland, Australia, says it is supporting Emesent in its pursuit of developing and testing light detection and ranging (LiDAR) scanning and automation technologies in real underground mining environments.

The team from Emesent were recently on site at Cannington with Spot the Robot Dog, trialling Spot’s autonomy development and capabilities in the underground silver-lead mine.

While the technology is still in its research and development phase, it has the potential to guarantee safer outcomes and ultimately transform the way Cannington operates, South32 says. Mining work safety and productivity can be improved by deploying the autonomous capabilities of Spot in various potential scenarios with different data capturing tools, including scanning, video recording and heat sensing, it added.

The focus on site was testing Spot’s capability in ‘post blast re-entry’ scenarios and emergency response. Spot, with an integrated LiDAR scanner, autonomously navigated sections of the mine, travelling through uneven and wet ground without operator intervention and exploring unlit areas. It was able to produce a 3D Point Cloud map of the underground mine in the process, South32 said.

The Cannington team has previously worked with Emesent to help develop industry-leading technologies including its Hovermap System for underground scanning, which is now used in mines all over the world.
