Perenti’s AMS extends contract at Resolute Mining’s Mako mine

Perenti-owned African Mining Services (AMS) has been awarded a contract extension for surface mining activities at Resolute Mining Limited’s Mako gold mine in Senegal, it says.

The revised contract is valued at approximately $85 million over a period of four years, commencing on January 1, 2023.

Through AMS, Perenti has provided surface mining activities at the Mako mine since 2017.

Mako is owned and operated by Resolute’s Senegalese subsidiary, Petowal Mining Company S.A. Resolute has a 90% interest in Petowal and the Government of Senegal holds the remaining 10%.

It is a conventional drill and blast, truck and shovel operation with mining services undertaken by AMS. The carbon-in-leach processing plant has greater than 2 Mt/y of installed capacity and comprises a crushing circuit, an 8 MW SAG mill and gold extraction circuit.

MMG brings in new Sandvik equipment for owner-operator transition at Dugald River

MMG Limited has acquired new underground equipment for its Dugald River zinc-lead mine in Queensland, Australia, as it gears up to make the transition from a contract miner-led operation to a run of mine (ROM) owner-operator model in 2023.

Among the purchases are three Sandvik DL421-15C longhole drills that will allow the team to drill holes up to 54 m in length and 115 mm in diameter.

A further seven Sandvik TH663i 63-t-payload underground haul trucks (pictured) have been purchased to support operations.

“These important acquisitions support Dugald River’s new operating model as ROM owner operator into 2023,” the company said.

Dugald River’s mining operations were previously overseen by Perenti-owned Barminco as part of a production and development contract which ends on December 31. Redpath Australia was awarded a new underground mining services contract at the mine, earlier this year.

Perenti’s Barminco to carry out development works at Evolution Mining’s Ernest Henry mine

Australia-based Perenti has provided an operational update and an upgrade to its financial year 2023 guidance to end-June 2023, which includes confirmation of a new contract for Barminco at Evolution Mining’s Ernest Henry mine in Queensland and a variation to expand its work scope at Regis Resources’ Garden Well mine in Western Australia.

The positive momentum noted in the operational update released on November 14 has continued as Perenti heads toward the end of the calendar year, with this momentum expected to continue into 2023, it noted.

“Since the release of the most recent operational update Perenti has secured improvements to commercial conditions across several Australian and African projects, including retrospective rate adjustments in relation to work that has previously been completed,” it said.

“These rate adjustments are the key catalyst in providing a further guidance upgrade one month after our previous upgrade.”

The contract at Ernest Henry (pictured) is for development work at the underground gold and copper mine. As Barminco transitions out of MMG’s Dugald River mine – where it has been carrying out development and production works – early next year, employees and capital resources from Dugald River will be mobilised to the new contract at Ernest Henry, it said. Underground development work at Dugald River, meanwhile, is to be taken on by Redpath Australia.

The Garden Well extension follows the commencement of underground mine development at the deposit in 2021.

On November 14, Perenti updated its FY23 guidance to forecast FY23 revenue of between $2.6-$2.7 billion ($1.7-1.8 billion). With the announcement of improved commercial conditions, and in consideration of securing work at Ernest Henry and scope growth at Garden Well, Perenti now forecasts that the company’s FY23 revenue will be between $2.7-$2.9 billion.

Mark Norwell, Managing Director and CEO of Perenti, said: “In addition to generating greater returns in FY23, we are focused on continuing to pursue business and project optimisation initiatives which will facilitate the delivering our 2025 strategy. Our strategy is designed to drive positive momentum in shareholder value well into the future. Perenti’s outlook is underpinned by our world-class Contract Mining Division, and the continued development of our Mining Services and idoba divisions. Our focus on generating enduring value for our people, clients and communities, will ensure we continue to deliver sustainable returns for our shareholders.”

ABB and Perenti to collaborate on mining electrification projects

Perenti has signed an agreement with ABB to collaborate and explore approaches to support net-zero emissions targets for underground and open-pit mines.

Experts from the two companies will work together to address electrification in mine hauling operations, power distribution, energy efficiency and power management, the companies said.

Australia-based Perenti has mining expertise and technical capability, which complements ABB’s technology expertise. Together, the teams plan to explore business models and solutions to provide wider services for pilot, brownfield and greenfield mining customer projects to support the electrification of operations.

ABB has been calling for open collaboration within the mining industry and has taken action on several similar initial non-binding agreements to build commitments with original equipment manufacturers (OEMs), technology innovators and mining companies. This includes pacts with FLSmidth, Amazon Web Services, MEDATech, Liebherr and others.

“Mining customers are committed to facing environmental, societal and economic challenges head on as they aim to decarbonise mining operations,” Joachim Braun, Division President, Process Industries, ABB, said. “With ABB’s sector leading position in electric mine technology development, and Perenti’s excellence and experience in mine development and mine operations, the scope of this collaboration is a perfect opportunity to make real progress in providing electric solutions that will decarbonise the industry.”

Mark Norwell, Managing Director and CEO, Perenti, said: “ABB and Perenti share a vision to develop energy-efficient solutions for the mining industry. By combining our experience across mining operations and digital solutions with ABB’s leading technologies we are focused on supporting the decarbonisation of mining through electrification. We look forward to working with ABB on this exciting new venture.”

ABB launched its ABB Ability™ eMine portfolio of technologies and methodologies last year, an approach to make the all-electric mine possible, with fully integrated electrification and digital systems from mine to port.

Perenti says it is committed to acting on climate change through promoting innovation, developing and deploying low emissions technology and working with its clients to implement projects that improve energy efficiency and reduce emissions.

Barminco extends relationship with Evolution Mining at Cowal gold mine

Perenti Group’s underground mining business Barminco is to further strengthen its relationship with Evolution Mining, having been awarded a new A$60 million ($42 million) contract to carry out diamond drill work at Cowal Gold Mine operations in New South Wales, Australia.

The four-year contract will see Barminco use state-of-the-art drill rig technology to improve safety, performance and productivity, it says.

It’s the second contract to be secured by Barminco at the Cowal operations in two months, after recently winning a A$520 million underground and development contract.

This latter contract will see Barminco carry out all underground development and production works at the underground mine where it is currently developing an exploration decline.

Last year, the Evolution board and regulators approved the development of the Cowal Underground Mine, which is set to provide a higher-grade ore source that will be blended with the current E42 open pit and stockpile ore. The development is part of the group’s goal of Cowal producing 350,000 oz/y of low-cost gold and extending the operation’s mine life.

Zero Automotive overcoming barriers with BEV conversion offering

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Perenti’s idoba collaborating with Sumitomo on sustainable mining solutions

idoba, Perenti’s technology driven products and services business, says it has been collaborating with Sumitomo Corporation under a Memorandum of Understanding (MoU) for the co-creation and joint development of digital mining products for the advancement of sustainable mining practices.

Sumitomo is a major investment and trading group, consisting of over 900 companies in 112 countries. It will, Perenti says, leverage its global mining industry network to bring a unique user perspective that will complement Perenti and idoba’s mining services and technology expertise.

Under the terms of the MoU, Sumitomo and idoba will collaborate and jointly develop digital mining services, including mining process optimisation and carbon footprint management. Included within this is:

  • Mining process optimisation – by connecting and analysing mine performance data to predict future performance and provide decision support; and
  • Carbon footprint management – to generate predictive decision guidance that will help mine owners on their pathway to net zero carbon equivalent emissions, while optimising cashflow and performance against global emission standards.

Mark Norwell, Managing Director and CEO of Perenti, said: “Our agreement with Sumitomo is a vote of confidence in idoba’s industry-leading capability. The combination of Sumitomo, idoba and our contract mining expertise will support our business evolving to meet the needs of the ever-changing mining industry and global expectations.

“In idoba we are building an innovation-based business with a focus on helping clients achieve operational excellence and world’s-best environmental performance through product and service development.”

Sarah Coleman, Chief Executive Officer of idoba, added: “The mining industry recognises the value that advanced digital technologies bring to operational performance, asset efficiency and sustainable business.

“The MoU with Sumitomo will help us expand our suite of technology driven products and services to meet the mining industry’s demand for technology and sustainability to be integrated with mining domain expertise, and a human-centred approach.”

Last year, Perenti launched idoba, calling it a “new capital light technology-driven service offering” available to the mining and resources industry aimed at providing digital product and technology services to the sectors. This followed Pereti’s July 2020 acquisition of Sandpit Innovation and Improvement Resources (a consultancy) and, in April 2021, the buy of Optika Solutions (a software product and solutions development company).

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

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

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

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

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

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

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

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

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

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

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

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

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

Perenti’s Barminco seals Savannah nickel project contract

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

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

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

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

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

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

Savannah has outlined a 12-year mine life with an average annual production target of 9,072 t of nickel, 4,683 t of copper and 676 t cobalt in concentrate. The mine is set to operate at average site all-in costs of A$6.36/lb of payable nickel, net of copper and cobalt by-product credits and royalty payments. This equates to roughly $4.86/Ib or $10,714/t.

The operation, with more than A$100 million already invested, has been maintained since the suspension of operations in April 2020 with a view towards operational readiness and project optimisation. This includes the recent completion of the FAR#3 ventilation raise, underground capital development on four mining levels at Savannah North and ancillary capital works on surface and underground infrastructure, which are currently being completed, Panoramic says.

Perenti boosts Botswana portfolio with Sandfire Motheo copper project contract

Perenti Global Ltd says its surface mining business in Africa, African Mining Services (AMS), has been awarded the contract for open-pit mining services at Sandfire Resources’ Motheo copper project in Ghanzi, Botswana.

The contract, which is yet to be finalised, has an estimated value of $496 million over an initial seven-year-and-three-month term with a provision for a one-year extension.

Under the terms of the Mining Services Contract, AMS will identify a suitable local Botswana company or companies as a joint venture partner for the project and transition to the joint venture before the commencement of mining in early 2022.

Finalisation of the contract is contingent on the satisfaction of two primary conditions, namely Sandfire being granted a mining licence for the project; and finalising the terms of the Mining Services Contract.

Perenti Managing Director and Chief Executive Officer, Mark Norwell, said Motheo represented a game-changing growth opportunity for AMS and will substantially increase Perenti’s presence in Botswana.

“Growing our footprint in Botswana is aligned with our 2025 strategy, to further expand into stable mining jurisdictions and pursue quality projects. The benefit of adding Motheo to the Perenti project portfolio is the opportunity to leverage our existing in-region operational presence at Zone 5 (owned by Khoemacau Copper Mining) as well as partnering with Sandfire to develop Botswana’s next large-scale, highly productive, world-class copper mine.

“The Motheo project is another positive step in the ongoing transformation of our AMS business as we seek to create value and certainty for our client Sandfire and the Ghanzi community.”

Motheo is in the Kalahari Copper Belt, an emerging and relatively underexplored copper producing region. It is around 200 km to the southwest of the Khoemacau Zone 5 project, where Perenti, through its subsidiary Barminco, is currently engaged to undertake underground mine development works.

Motheo is held through Sandfire’s subsidiary, Tshukudu Metals, and was approved for development by Sandfire’s Board of Directors in December 2020 following completion of a definitive feasibility study (DFS) on a base case of a 3.2 Mt/y operation with expansion potential.

The DFS outlined an initial 12.5-year operation, underpinned by an updated ore reserve of 39.9 Mt at 0.9% Cu and 12.2 g/t Ag for 360,000 t of contained copper and 15.6 Moz of contained silver, producing on average circa-30,000 t/y of contained copper and 1.2 Moz/y of contained silver over the first 10 years of operations.

Perenti Mining Chief Executive Officer, Paul Muller, said: “Through this commitment and the establishment of a local joint venture partnership, we expect that more than 95% of the workforce will be citizens of Botswana. Furthermore, and leveraging our existing Maun based state-of-the-art mining training centre, our workforce will have access to the latest mining techniques and technology to enable the creation of a safe, highly skilled and productive workforce to support economic growth and diversification within Botswana.”

Muller said the company was also excited by the opportunity to deploy “future-focused mining technology initiatives” on the project that not only provide expected productivity and safety benefits to Sandfire but are also aligned with the two firms’ sustainability goals.

Perenti anticipates pre-production work to commence in late 2021 with mining to commence in early 2022.
