Rio Tinto funds initial underground development at Kennecott copper ops

Rio Tinto has approved a $55 million investment in development capital to start underground mining and expand production at its Kennecott copper operations in Utah, USA.

Underground mining will initially focus on an area known as the Lower Commercial Skarn (LCS), which will deliver a total of around 30,000 t of additional high-quality mined copper through the period to 2027 alongside open-pit operations, Rio says. The first ore is expected to be produced in early 2023, with full production in the second half of the year. It will be processed through the existing facilities at Kennecott, one of only two operating copper smelters in the US.

Kennecott holds the potential for significant and attractive underground development. The LCS is the first step towards this, with a mineral resource of 7.5 Mt at 1.9% Cu, 0.84 g/t Au, 11.26 g/t Ag and 0.015% Mo identified based on drilling and a probable reserve of 1.7 Mt at 1.9% Cu, 0.71 g/t Au, 10.07 g/t Ag and 0.044% Mo.

Underground battery-electric vehicles are currently being trialled at Kennecott to improve employee health and safety, increase productivity and reduce carbon emissions from future underground mining fleets. A battery-electric haul truck and loader supplied by Sandvik Mining and Rock Solutions – a Sandvik LH518B 18 t battery-electric LHD and a Sandvik Z50 50 t battery-electric haul truck – are being used to evaluate performance and suitability as part of underground development work.

Rio Tinto Copper Chief Executive, Bold Baatar, said: “This investment will allow us to quickly bring additional volumes of high-quality copper to the market and build our knowledge and capabilities as we evaluate larger scale underground mining at Kennecott. We are progressing a range of options for a significant resource that is yet to be developed at Kennecott, which could extend our supply of copper and other critical materials needed for electric vehicles and renewable power technologies.

“Trialling underground battery-electric vehicles is an exciting step in our work to create a safer workplace for our employees, increase the productivity of the mine and reduce emissions from our operations. We look forward to seeing their potential for deployment.”

Existing undergound infrastructure is currently being extended to enable early access to the next underground resource and undertake characterisation studies. A feasibility study to inform decisions on the next phase of underground production is expected to be completed in 2023. This will be one of several potential stages currently being investigated.

Feasibility studies are also being progressed to extend open-pit mining at Kennecott beyond 2032.

Newcrest’s Brucejack mine set for full fleet battery-electric transition in Q4

Newcrest’s Brucejack gold-silver mine in British Columbia, Canada, is set for a full battery-electric fleet transition by the end of the year, the gold miner said in its financial year 2022 results.

Following a successful site trial, seven underground battery-electric trucks are being commissioned at Brucejack, replacing the existing diesel fleet and abating approximately 65,000 t of CO2 emissions through to 2030.

The new fleet will improve truck productivity, lower unit costs and enhance operational efficiency from planning to production, according to Newcrest. Three of the Sandvik 50-t-payload Z50 battery-electric trucks are already in production, with the full switch over expected to be completed in the December 2022 quarter, it noted.

Sandvik and Pretivm previously noted that seven Z50 haul trucks would be supplied to the operation as part of the planned fleet transition.

The project is being partly funded thanks to a C$7.95 million ($6.1 million) investment from The CleanBC Industry Fund.

Brucejack, which became wholly owned by Newcrest when the acquisition of previous owned Pretivm Resources completed earlier this year, is currently the subject of Newcrest’s EDGE program, which aims to drive a culture of innovation, high performance and continuous improvement. The program has identified additional opportunities of approximately C$15-$25 million/y, with improvements in stope turnaround time and more efficient mine operations as the initial focus areas, the company said.

Run-rate benefits from this effort are expected to be fully realised by the June 2024 quarter, Newcrest says.

Newcrest said in the financial results that it was also assessing ore sorting technology at the mine, which aims to classify and separate mineralised material from non-mineralised material to deliver more consistent mill feed grades and increase operational flexibility.

Sandvik leveraging global supply chain network for battery-electric vehicle deliveries

Sandvik Mining and Rock Solutions recently dispatched its first Z50 battery-electric truck from its Winnipeg facility, in Canada, in a move that, it says, underlines the company’s ability to continually optimise its global supply network in the face of growing demand for its solutions.

The mining OEM can assemble a limited number of battery-electric vehicles in Canada, with this capability reducing the emissions associated with transport to the mine site and improving delivery efficiencies.

The company’s battery technology centre of excellence is in Camarillo, in the US, which supports the Winnipeg branch and other facilities in delivering these electric machines. The division headquarters in Turku, Finland, provides additional support where needed.

Sandvik told IM that decisions on the local build options are conducted at an operational level, although battery manufacturing is currently concentrated in California.

It added: “Sandvik is constantly optimising its global supply network. We have manufacturing locations all over the world which are helping us to adjust our manufacturing base when needed. Presently, the Sandvik battery and hybrid electric vehicle (BHEV) business unit is ramping up and there is need for additional capacity. One part of our solution is the decision to utilise our facility and expertise in Winnipeg as support.”

The Z50 battery-electric vehicle has a 50-t payload and leverages Artisan™ battery packs and electric drivelines. It has been deployed at mine sites across North America and Australia, with plans for further deployments in Europe (with LKAB) and Africa (with Gold Fields at South Deep) later this year.

Another major Sandvik battery-electric development in Canada recently occurred with the award of a contract to deliver 10 underground battery-electric loaders along with one electric tethered loader for use at the Jansen Potash project in Saskatchewan. Delivery of the battery-electric loaders and other equipment – including a fleet of cable connected electric MF460 borer miners developed as part of a Sandvik-BHP collaboration over a number of years – is scheduled during 2023 through till 2025.

Barrick Gold’s Artisan Z50 battery-electric trial paying off at Turquoise Ridge

Barrick Gold’s decision to carry out a three-year production trial using Artisan Z50 battery-electric vehicles at the Turquoise Ridge gold mine looks to be paying off, with underground tonnage mined at the joint venture operation increasing during the most recent quarter.

Back in November, Sandvik and Barrick confirmed the signing of a partnership agreement for trailing and enhancing battery-electric vehicles (BEVs) for underground hard-rock mining. This would see a three-year production trial take place where Sandvik would deploy four Artisan Z50 BEV trucks at the Turquoise Ridge gold mine, part of the Nevada Gold Mines joint venture where Barrick is the 61.5% owner and operator.

In the company’s just-released June quarter results, Barrick reported that Turquoise Hill gold production in the June quarter was 15% lower than the prior quarter mainly due to an extended planned maintenance shutdown at the Sage autoclave. It noted that upgrades to the autoclave during the shutdown were expected to deliver improved reliability and performance in the second half of 2021.

And, while total tonnes mined decreased 12% compared with the prior quarter – driven by lower open-pit production – underground tonnes mined improved 11% quarter-on-quarter it said.

In this three-month period, Turquoise Ridge benefitted from “efficiency gains from the Sandvik Z50 electric haulage trucks at Turquoise Ridge” and higher tonnes mined from the Vista underground after remediation efforts were completed in the March quarter of 2021 following the previously disclosed fall of ground, it said.

While the use of the Z50s benefitted tonnage mined in the quarter, Barrick did not in its follow-up quarterly presentation that it was “working with Sandvik to address ongoing issues with batteries”.

Still on Turquoise Ridge, Barrick reported that shaft sinking on the Third Shaft at the mine had advanced to its final depth of 989 m below the collar in the quarter.

Construction of the Third Shaft, which has a hoisting capacity of 5,500 t/d, continues to advance according to schedule and within budget, it noted, with commissioning in late 2022. The focus of the project is now shifting from sinking activities to equipping in the September quarter.

Together with increased hoisting capacity, the Third Shaft is expected to provide additional ventilation for underground mining operations as well as shorter material haulage distances, according to Barrick.

As at June 30, Barrick had spent $201 million (including $17 million in the June quarter) out of an estimated capital cost of around $300-$330 million (100% basis).

Thyssen Mining is carrying out the shaft sinking project at the Third Shaft.

Sandvik on the growth path with Artisan as mine electrification takes hold

Sandvik’s Artisan business unit is continuing to ride the battery-electric vehicle wave in mining, having just moved premises in California, USA, to expand its production and testing capabilities.

Based in Camarillo, Artisan has been on a steep growth trajectory since it was established just over a decade ago. Having initially manufactured machines for several OEMs in the mining sector, the company was acquired by Sandvik in 2019. It had revenues of $12.3 million and approximately 60 employees back in 2017.

Both of these numbers have accelerated in line with increased take-up – and an expansion – of its battery-electric solutions for mining since it became a business unit of Sandvik.

Artisan’s 4-t (A4) and 10-t (A10) battery-electric underground loaders have found their way into mines in Canada and the US, while its 50-t Z50 haul truck has found a home in mines in Canada, the US and Australia. One of the bigger deployments has been at the Barrick Gold majority-owned Turquoise Ridge underground mine in Nevada, USA.

More recently, the portfolio was broadened with an 18 t LHD called the LH518B. This machine is the first true collaborative design effort between Sandvik and Artisan, marrying Sandvik’s underground mining engineering expertise with the Artisan™ battery system and electric driveline to “best leverage the possibilities that the battery technology brings”, the companies say.

This machine’s first deployment will be at a gold mine in British Columbia, Canada, but Artisan has also booked several orders for it in Australia, one of these being for Kirkland Lake Gold’s Fosterville gold mine, in Victoria.

With a range of new battery-powered equipment in the pipeline, Artisan has moved into a larger facility in California that will help it build these new vehicles from the ground up.

“We’re definitely growing in Camarillo,” Artisan’s Vice President of Technology, Brian Huff, told IM recently. “The move to a larger facility comes at the same time we are ramping up a lot of hiring in terms of engineering and manufacturing personnel.”

Artisan’s new facility comes with a test ramp with a 20% grade and a whole area for mucking on the property (pictured above).

“This will allow us to do a lot more development testing in a short period of time, giving us an advantage in terms of validation testing and trials of new designs and tools,” Huff said.

The potential for speeding up Artisan’s time to market will be increasingly important as more mines replenish fleets with battery-electric equipment.

As COVID-19-related restrictions ease, expect the new testing facility – and the manufacturing plant – to be regularly frequented by mining companies eyeing these new solutions.

Tackling the big mine electrification questions

“There is consensus in the industry that once we start doing electrification, we will innovate much more in other areas of the mining space.”

If anyone in the mining sector thought electrification was not in their wheelhouse, Theo Yameogo’s words might make them think again.

Yameogo, Partner and National Mining & Metals Co-Leader at EY Canada, made such a statement during The Electric Mine Virtual Conference earlier this week. The event, organised by International Mining Events, brought leaders in the electrification space together to discuss the latest developments in the industry, of which there were many.

The stage was set for mine electrification reveals, and Henrik Ager, President of Sandvik Mining and Rock Technology (soon to be Sandvik Mining and Rock Solutions), did not disappoint, acknowledging that the company is currently working on development of what would be its largest underground truck: a battery-powered 65 t vehicle.

This was all part of the company’s aim to have a “full range electrified offering by 2022”, he said.

Azizi Tucker, Co-Founder and CTO of XING Mobility, was next up, providing an overview of the Taiwan-based company’s offering in his presentation: ‘Electrification from prototype to mass production’.

With a remit to provide commercial, industrial and specialty vehicle makers with modular, high power and safe battery and powertrain technologies, XING is making an entrance into the mining space at just the right time.

Tucker talked attendees through the elements that make the company’s IMMERSIO™ battery solutions ideal for the mining sector: “With the modular size and shape of our batteries, we can really suit any vehicles. We find this very popular with the original equipment manufacturers (OEMs) as they can utilise their existing chassis.”

The elimination of corrosion, ability to operate consistently in high-temperature environments, a variety of sealing techniques and the use of nickel-manganese-cobalt lithium-ion chemistry has allowed the company to provide the safe and enclosed battery solution miners are looking for.

He concluded by saying XING was in conversation with a variety of mining companies, mining OEMs and mine site operators about deploying solutions in the space.

Attendees were then treated to a demonstration of Tembo 4×4 e-LV’s Electric Cruiser via video during the session: ‘Green conversions: the Tembo 4×4 e-LV electric light utility vehicle platform’ (pictured below). They got up close and personal with the battery-electric utility vehicle as it travelled on- and off-road close to the company’s Netherlands HQ.

After a 15-minute demo showing off the Electric Cruiser’s attributes, Paul Smeters, Tembo 4×4 e-LV’s Marketing Manager, and Alexander Haccou, Tembo 4×4 e-LV’s Technical Director, joined the event to answer audience questions.

The inevitable query came up early during the live Q&A: have you tested this vehicle in an underground mine?

Haccou was prepared for this, explaining that Boliden’s Tara underground zinc-lead mine in Ireland was the first recipient of the company’s Electric Cruiser, and a unit had been operating there for a few years now observing many of the maintenance benefits battery-electric machines are becoming renowned for.

The Electric Cruiser has also been tested in Australia and Canada with the help of Tembo 4×4 e-LV partners in those regions, he added.

“We don’t use fast charging or battery swapping,” Haccou said in response to another question. “What we have seen in several mines is the daily amount of usage is less than the battery’s full capacity.”

After several questions related to an active thermal management system for batteries had come up in previous sessions, Nicolas Champagne’s entrance to the virtual event proved timely.

His presentation, ‘Battery thermal management system using a highly advanced dielectric fluid’, homed in on the use of a dielectric fluid with specific features to allow direct cooling of the battery electrochemical cells.

Champagne, Formulation Team Manager of the R&D department for TOTAL Lubricants, revealed results from use of the fluid in bench tests and simulations at the battery pack level, extrapolating what these results could mean for battery-powered vehicles in the mining sector.

He said the company is in discussions with at least one mining customer about deploying its fluid on a battery-powered vehicle.

After previous sessions had discussed the potential for fast charging and battery swapping, Champagne made clear that TOTAL Lubricants’ solution would prove beneficial in all battery-powered applications throughout the mining sector.

 

Following a lunch break, it was the turn of Epiroc’s Anders Hedqvist (Vice President of R&D, underground) and Franck Boudreault (Electrification Transformation Lead, underground) to deliver a scoop (pun intended).

The pair, during their presentation, ‘From one generation to the next – learnings from zero emission mining’, took it in turns to provide updates.

Boudreault revealed the company’s plan to create battery-electric conversion kits for not only Epiroc diesel-powered equipment out in the field but other OEMs’ machines, before Hedqvist disclosed the company’s in-development battery-electric 18 t LHD would be trialled at LKAB’s Sustainable Underground Mining (SUM) project in Sweden. Epiroc has already delivered a diesel-powered Scooptram ST18 to be trialled in autonomous mode at the SUM project.

It was Yameogo, a mining engineer with much experience operating in underground mines in Canada, that provided the event’s big picture talk in his presentation, ‘Will electrification spark the next wave of mining innovation?’

He talked up the need for industry collaboration between miners, OEMs and service providers in not only electrifying equipment and operations, but also other types of technology.

“That type of collaboration and co-creation framework will actually help mining companies also think about innovation and other items part of electrification and equipment, in general,” he said.

The focus narrowed slightly to open-pit electrification during Dr Bappa Banerjee’s talk, ‘An electric future for mine haulage’. Dr Banerjee, General Manager of Mining Equipment for Wabtec, emphasised from the off that there was no one-size fits all solution to going electric in this sector.

“It’s becoming clear to us…that perhaps it will be a combination of technologies that really help us get to a solution that is feasible,” he said.

This solution, he said, depended on the mine application and haulage scenario, underlining the need for technology flexibility.

In his presentation, Dr Banerjee pitted a diesel-powered haul truck with 2,500 horsepower (1,864 kW) as his baseline solution against a hybrid solution with a 2,500 hp diesel engine and 200 kWh battery as one alternative, and all-electric truck platforms equipped with trolley assist (with 800 kWh battery) and stationary charging (1,200 kWh battery).

The energy cost versus productivity outcome he showed proved his earlier point about different applications suiting different solutions, with varied results depending on if these trucks were deployed on downhill, uphill or flat hauls.

GE Transportation, since merged with Wabtec, has previously demonstrated a battery-diesel hybrid solution on a Komatsu 830E-1AC and Wabtec has plans to release trolley solutions for Komatsu 830E-5 and 930E-5 haul trucks in 2021, so this analysis includes hard industry data.

Dr Banerjee concluded on the decision-making aspect of going electric: “These are not just point in time decisions we have to make regarding the CAPEX and where we are in the lifecycle of the mine, but decisions across decades sometimes.

“Perhaps the best way to approach this would be to start with a technology that is more flexible up front or has more options.”

Brian Huff, Vice President of Technology for Artisan Vehicle Systems, a Sandvik Mining and Rock Technology business unit, used his presentation to reinforce that battery-powered solutions were the way forward in the underground environment.

‘Rethink the machine, not the mine’ was the title of his presentation and Huff stayed true to it from the off: “The basic message is that this is not as hard as you think it is. There is a real big change coming to the mining industry, but it may not be as difficult as you think to accomplish a conversion to battery-electric equipment.”

Similar to Hedqvist’s mention of the newfound freedom available to engineers when designing these next generation battery-electric machines, Huff explained that Artisan’s generation three BEV blueprint started with a battery-electric driveline and built from there.

“Major parts of the frame can be removed to facilitate swapping…[and you can have] double to triple the power density of the machine (compared with the diesel-powered equivalent) to improve performance,” he said.

He moved on to tackle the usual range anxiety question head on, displaying a video of a 13 km haul on a one-in-seven grade. Within this, he showed that the ability to swap batteries during the uphill haul meant there was no loss in haulage productivity when compared with the a similar payload diesel-powered machine.

The time losses related to battery swapping – around six minutes per swap with the Z50 – were more than offset by the increased haulage speed, according to Huff. “It is about 10% faster on the climb,” he said when comparing the BEV unit with a conventional diesel truck.

Productivity could be further boosted with the introduction of Artisan’s patented AutoConnect system. Fitted on the company and Sandvik’s newest 18 t payload LH518B LHD, this system allows the battery swap to be completed in well under five minutes, according to Huff. IM understands an AutoConnect retrofit option could allow the Z50 haul truck to match that swap time.

Add to this productivity benefit, decreases in operating cost and total cost of ownership, and it is hardly surprising Barrick recently signed off on a trial of four of these Z50s at its Turquoise Ridge joint venture gold mine in Nevada.

Safety, cost, maintenance, productivity and even battery life; you name it, The Electric Mine Virtual Conference discussed it.

The good news is a second dose of electrification talk is only four months away, with The Electric Mine 2021 conference taking place on March 15-16, 2021, in Stockholm, Sweden.

Sandvik and Barrick confirm Artisan Z50 trials at Turquoise Ridge gold mine

Sandvik and Barrick have confirmed the signing of a partnership agreement for trialing and enhancing battery-electric vehicles (BEVs) for underground hard-rock mining.

During a three-year production trial, Sandvik will deploy four Artisan Z50 BEV trucks at the Turquoise Ridge gold mine, part of the Nevada Gold Mines joint venture (JV), Sandvik said. Barrick is the operator of the JV, which is the single-largest gold-producing complex in the world, forecast to produce a total of 3.4-3.65 Moz of gold during 2020.

The announcement follows an acknowledgement of such a deal by President of Sandvik Mining and Rock Technology, Henrik Ager, earlier this month.

The Z50 haul truck, with a 50 t payload capacity, is a ground-up design that seamlessly integrates the most capable and proven battery electric powertrain available in the mining industry with the latest and most coveted features of any haul truck on the market today, according to Sandvik.

It is equipped with AutoSwap, a patented self-swapping system for the Artisan battery pack. This makes battery swapping faster and easier with a minimum amount of manual handling: changing the battery only takes about six minutes, and it can be done in a passing bay or old re-muck bay with no overhead cranes or external infrastructure needed.

In phase 1 trials, the Z50 truck already achieved more than 1,400 hours of production with over 1,400 loads, according to Sandvik. It reached production operation of up to 18 hours per day, with speeds of over 10 km/h observed on the ramp to the tip.

Some of the key performance indicators in the new partnership will include the performance of the BEV technology in a production environment, mechanical availability, average lifecycle cost and overall production cost, Sandvik said.

“We are always looking at ways to improve our performance, both in terms of sustainability and operational efficiency,”  Mark Bristow, Barrick’s President and CEO, said. “This partnership with Sandvik is exciting and will give us first-hand experience in BEV technology in our own production environment. It is a significant step to furthering our BEV strategy across the group.”

Ager added: “I am very pleased that Barrick and Sandvik have teamed up to perform these extensive trials in a daily production environment. It gives us the possibility to prove the performance of our BEV technology.

“The purely battery-powered truck helps to reduce heat and emissions underground, helping mines reach their sustainability targets and reduce ventilation costs. This raises the bar for what is possible and enables an all-new level of production and cost reduction for underground hard rock mines.”

A dedicated site project team will be jointly working with the Barrick operations team during the trial period to ensure that all data is captured and the experience from both Sandvik and Barrick is used to ensure the uptime and productivity targets are met, Sandvik said.

Barrick to receive three more Artisan Z50 battery-electric trucks, Ager says

Sandvik Mining and Rock Technology has signed an agreement with Barrick Gold that could see four Artisan Z50 battery-electric trucks deployed at the miner’s majority-owned operations in Nevada, Henrik Ager confirmed this week.

Speaking at Sandvik’s Capital Markets Day on Tuesday, Ager, President of Sandvik Mining and Rock Technology (soon to be President of Sandvik Mining and Rock Solutions), said the company had just signed “a cooperation partnership” with Barrick in relation to the delivery.

“We have one (truck) operating already and have three coming,” he said.

Back in May, a Barrick spokesperson confirmed to IM that an ongoing trial involving a 50-t payload Z50 was expected to be finalised in the June quarter of this year, “with the option to extend, should the KPIs not be met”. The machine was being tested at Turquoise Ridge, a gold mine operated under the Nevada Gold Mines company, owned 61.5% by Barrick and 38.5% by Newmont.

Based on this order, IM assumes the Turquoise Ridge trial was a success.

Alongside this reveal, Ager, talking up the company’s next-generation AutoMine® Concept vehicle recently revealed at the Innovation in Mining event, said the company currently had automation solutions at 59 sites across the mining industry. This compared favourably with solutions at 43 sites 18 months ago, and 19 sites back in 2016.

Sandvik to show off newest battery-electric loader next week

Sandvik Mining and Rock Technology is set to announce details of its new battery-electric LHD at its Innovation in Mining Virtual Event next week, Brian Huff, has confirmed.

Speaking on ‘The Next Generation of Battery-Electric Vehicles’ event on Tuesday, Huff, Vice President of Technology at Artisan Vehicle Systems, a Sandvik Mining and Rock Technology Business Unit, said a new machine would be announced on September 29 at the virtual event. He later confirmed the loader in question would be on show.

Not too many details were given away about this new BEV, but Huff confirmed it would be “another machine to fill out our weight class” and host, Martina Lundgren, said the loader represented the first joint project between Artisan and Sandvik since Sandvik acquired Artisan in 2019.

In addition to announcing this news, Huff also confirmed that “there will be a larger class…haul truck intended mainly for the Australian market” coming from the company in later years.

As it stands, the company’s largest payload battery-electric haul truck is the Z50 50 t machine (pictured), which has been trialled at the Barrick Gold-owned Turquoise Ridge gold mine, in Nevada, USA.

Barrick continues to leverage automation and battery-electric technology

Barrick Gold, despite numerous COVID-19-related hurdles, made progress on the innovation front in the March quarter, with a haul truck automation trial and battery-electric underground equipment developments continuing to take place.

In its 2019 annual report, Barrick said the first stage of a project designed to retrofit an autonomous system at its Carlin gold mine, in Nevada, had been successfully completed.

In the March quarter results presentation last week, Mark Bristow, Barrick President and CEO, updated investors on this project, saying a proof of concept allowing manned and unmanned operations in the same zone had been completed at one of its mines. On top of this, the company said it was working on autonomous drilling projects.

It is underground where the biggest revelation came, with Barrick confirming trials of a 50 t battery-electric haul truck it mentioned in its 2019 annual report had commenced at its Turquoise Ridge gold operation, in Nevada. This trial involved an Artisan Z50 (graphic, pictured), the largest battery-powered underground haul truck currently on the market.

A Barrick spokesperson said the trial of the 50 t payload truck was expected to be finalised in the June quarter of this year, “with the option to extend, should the KPIs not be met”.

Barrick previously reported the introduction of a battery-powered development drill at its Hemlo underground gold mine, in Ontario, Canada, “as a first step towards establishing the potential of this new technology” in 2019. Having carried out a trial of this Sandvik DD422iE battery-powered development drill, the Barrick spokesperson confirmed the company has now acquired the unit.

Designed to use electric energy from an onboard battery during tramming and plug into a mine’s existing energy infrastructure while drilling, the Sandvik DD422iE has been used at Newmont’s Borden mine, in Ontario, among other places.

Bristow said on the call that the company believes battery-powered electric underground equipment “has the potential to lower operating costs and increase efficiencies”.

In addition to these automation and battery-electric vehicle developments, Barrick said in the results that a new global SAP Enterprise Resource Planning system was on track for its first implementation at the Nevada Gold Mines JV operations in the September quarter. This is a “more agile, less overly-customised tool, focused on getting the right information”, according to Barrick.

“This more streamlined and standardised global design will further improve our ability to report real-time cost and efficiency data and, more importantly, manage our real-time information,” Bristow said on the call.

The NGM JV implementation could lay the groundwork for a solution to be rolled out to other regions in 2021, according to Barrick.

Barrick’s underground digital innovation plan has seen the company recently adopt technologies that allow it to remotely monitor, in real time, a machine’s location, productivity and health, as well as that of operators’, Bristow said. This tool could increase its efficiencies and predictive maintenance capabilities, he added.

Barrick’s team at Loulo Underground, meanwhile, has helped develop a system that automatically turns secondary fans on and off using personal RFID tracking systems, Bristow noted on the call. This could help reduce power consumption at the mine, in Mali, and the project is now being implemented across its Africa underground mines, he said.
