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.

Panoramic, Primero and Barminco get to work on restarting Savannah nickel operation

Panoramic Resources Ltd, after a 12-month review process, has approved the restart of the Savannah Nickel Operation, in the Kimberley region of Western Australia.

The decision hinges on 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; as well as an offtake agreement with Trafigura that will also see the trading company provide a loan facility of up to A$45 million to cover the A$41 million of upfront capital cost required to restart the mine.

Savannah 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.

Savannah, 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 said.

The restart decision has led to divisions of Perenti and NRW Holdings being awarded significant contracts related to the resumption of mining activities.

Barminco, a subsidiary of the Perenti Group, has been awarded a four-year underground mining contract under a binding letter of intent and is scheduled to mobilise to site in July 2021. 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.

The contractor was formally awarded the A$200 million contract back in February.

“Based on Barminco’s previous working knowledge at Savannah, opportunities to increase ore production and reduce dilution have also been identified,” the company added, explaining that underground mining is planned to commence in August, with ore to initially be sourced from both the Savannah and the Savannah North deposits.

Following an evaluation of an owner-operator model for the processing plant and a competitive contract tender process, Panoramic has also signed a non-binding letter of intent worth A$35 million with Primero (owned by NRW Holdings), which envisages a three-year agreement. The agreement relates to all processing and maintenance work at the Savannah processing plant, which has been maintained in “excellent condition” during the suspension, Panoramic said.

“A number of opportunities for improved recoveries through enhanced operating practices and minor capital projects have been identified,” the company added. As a result, the non-binding letter of intent with Primero has been structured to incentivise achieving higher than budget recoveries.

Panoramic is working with Primero to complete a binding contract in the coming months, but ore processing is set to restart in November 2021, allowing ore stockpiles to build for around three months (100,000 t) to de-risk ore supply issues.

The process plant at Savannah was commissioned in August 2004 and comprises a single stage crusher, SAG mill, flotation, thickening and filtering stages to produce a bulk nickel, copper, cobalt concentrate. Over the 2004 to 2016 initial operating period, metallurgical recoveries averaged 86-89% for nickel, 94-97% for copper and 89-92% for cobalt. The plant was originally designed for a throughput of 750,000 t/y, but consistently outperformed the design specifications with rates exceeding 1 Mt on an annualised basis, Panoramic said.

First concentrate shipment from the Wyndham Port is targeted for December 2021.

Barminco set for Normet battery-electric Charmec trial at IGO’s Nova operation

Normet’s Charmec MC 605 VE Smart Drive battery-powered emulsion charger is continuing its tour of Australia, with Barminco signing up to trial the machine for three months at the Independence Group-owned Nova nickel-copper-cobalt underground mine in Western Australia.

Barminco, a Perenti company, says the trial is part of its commitment to improving performance and driving sustainability initiatives across its business. It represents the contractor’s first heavy-duty battery electric vehicle (BEV) trial, coming on top of the short trial it conducted with Safescape’s Bortana light electric vehicle, also at Nova.

The MC605 VE Smart Drive will be a direct replacement for the diesel-powered MC605 D Barminco uses at its underground client sites, with the battery-electric trial likely involving a mix of production and development operations.

“Along with the maintenance and cost benefits of using battery-electric equipment underground, it will also provide an improved work environment for our people,” Barminco said.

OZ Minerals, in October, became the first miner in Australia to take delivery of a battery-powered Normet Charmec MC 605 VE SD. The charging unit, which arrived at the Carrapateena copper-gold mine in South Australia, was also put through a three-month trial.

The work at Carrapateena involved the charging of 30 faces – all of which were charged without any major problems – with tramming times of 5-15 minutes and tramming distances of 1-3.5 km from the explosives warehouse to the face and back, according to Normet. The process saw 4.5 m long cuts and an average of 65 holes, with 300-400 kg of emulsion loaded per cut.

The trial involved the use of an on-board 1.5 t Emulsion Charging Module system provided by Normet and the application of Downer Blasting Services’ HEAT® 9000 ammonium nitrate emulsion.

The unit carried out charging with and without a trailing cable plugged into the mine site’s electricity infrastructure and a SmartDrive CT40 DC-charging trolley was also employed.

Reflecting on the Carrapateena trial, Normet said: “SmartDrive battery-electric vehicle architecture proved its ability for emulsion charging as this process is extremely energy efficient and enables independent operations even without a trailing cable plugged in.

“Silent slope performance as well as exhaust-, heat- and noise-free charging operations made a real impression on all users of the SD Charmec.”

Back in 2019, Normet made history with the MC 605 VE Smart Drive by demonstrating battery-electric emulsion charging in an underground production environment for the first time in Europe at the Pyhäsalmi mine, in Finland.

Barminco bags A$200 million contract extension at Gold Fields’ Agnew mine

Perenti’s hard-rock underground miner Barminco says it has been awarded a A$200 million ($153 million) contract extension at Gold Fields’ Agnew gold mine in Leinster, Western Australia.

The extension is for full underground mining services, driven by an increase in development and production “physicals” at the mine, Perenti said, adding that Barminco has been operating at Agnew since 2010.

Perenti Managing Director and Chief Executive Officer, Mark Norwell, said: “We are delighted to be extending our relationship with our long-standing client, Gold Fields.

“Part of our 2025 group strategy is to organically grow this part of our business. The recent achievements of Barminco in this regard are a result of the strong relationships we share with our clients and the value we create for them through our world-class underground mining capabilities.”

Perenti Mining Chief Executive Officer, Paul Muller, said: “We have been providing safe and efficient underground mining services at Agnew for more than 10 years and we are very pleased to be supporting Gold Fields with their increased development and production requirements. This extension will take our current term out to December 2023.”

Gold Fields to trial Caterpillar dual-fuel solution on haul trucks at Tarkwa mine

Gold Fields plans to test the use of LNG to power haul trucks in a trial at its Tarkwa open-pit gold mine in Ghana, CEO Nick Holland told attendees of the IMARC Online event this week.

Speaking on a panel reviewing progress of the Innovation for Cleaner, Safer Vehicles (ICSV) initiative – a supply chain collaboration between the International Council on Mining and Metals (ICMM) and original equipment manufacturers (OEMs) – Holland said the trial would involve a mix of LNG and diesel fuel at the operation, and four trucks would initially be tested with the fuel combination in 2021.

Gold Fields later confirmed to IM that the trial would take place in the second half of 2021 and involve the use of Caterpillar’s dual-fuel LNG Dynamic Gas Blending (DGB) retrofit system on four of the mine’s Cat 785C 146 t payload dump trucks.

The DGB conversion kits, available on Cat 785C and 793D haul trucks, are a dual-fuel technology that enables miners to substitute diesel fuel with LNG, according to Cat. The use of LNG has been proven to reduce emissions by up to 30%, as well as lower costs by up to 30%, Cat says.

DGB vaporises liquid fuel into natural gas, then replaces diesel fuel with LNG when possible. On average, DGB replaces about 60-65% of diesel with LNG, according to Cat.

Tarkwa, which is 90% owned by Gold Fields, produced 519,000 oz of gold in 2019, 1% lower than the 525,000 oz produced in 2018. It employs Engineers & Planners Co Ltd as mining contractor.

While this trial will potentially lower the company’s carbon emissions – as will Gold Fields’ plan to fit “diesel filters” on all its machines underground in the next 12-18 months – Holland pointed to a much loftier long-term goal during the ICSV panel.

“The challenge to our teams and OEMs is to move away from diesel completely,” he said.

Such a move could see the company employ both battery-powered and hydrogen-powered solutions at its underground mines, he added.

Ausdrill commissions automation-ready Cat MD6250 drill at Boggabri

Ausdrill says it has just commissioned the first of four new Caterpillar MD6250 drills at the Boggabri coal operations in New South Wales, Australia.

The machine has been successfully commissioned on site four weeks ahead of the contract start date, according to the Perenti company, with the help of the WesTrac team at Tomago, NSW.

These M6250 drills come with the next level of drill automation and driller assist, Ausdrill says, including one touch auto levelling and auto drilling functions combined with Cat MineStar Terrain for drilling to improve safety, productivity, reliability and accuracy.

Back in February, Perenti reported its Surface Mining Industry Sector Group had been awarded A$155.5 million ($113 million) in new and extended contracts. This included a three-year contract (with options to extend) for production drilling services with Boggabri Coal Operations (a part of Idemitsu Australia Resources Group) at Boggabri.

The MD6250 is designed for both down-the-hole drilling in hard rock and rotary drilling in softer rock. The blasthole drill carries out single-pass drilling and multi pass, as well as angle drilling, according to Cat.

MACA is currently running an MD6250 at the Bluff coal mine, in Queensland, while AngloGold Ashanti Australia, with support from Flanders and Tropicana Mining Alliance partner, Macmahon Holdings, now has five autonomous Cat MD6250 drill rigs as part of its drilling fleet at the Tropicana gold mine, in Western Australia. Thiess, Cat and WesTrac have also introduced an MD6250 drill rig with autonomous drilling capability at Mount Pleasant, in New South Wales, in a phased 12-month pilot project.

Barminco starts round one of portal development at Barrick Hemlo

Barminco says it has mobilised to start the development of the new underground portal at Barrick Gold’s Hemlo gold mine in Ontario, Canada.

The installation of the portal ground support has been completed and a new Sandvik DD421 jumbo is being used to drill the first round of what will be the entrance to the new decline ramp, Barminco said.

It added: “Barminco is proud to be introducing high speed development capabilities at Hemlo, adding value to the already well-established mine.”

Earlier this year, Barminco was issued a letter of intent to provide underground contract mining services at Hemlo following Barrick’s decision to phase out open-pit mining and move to an underground contract mining model at the operation.

Perenti, Barminco’s parent company, said back then that its underground contract mining division would “bring industry-leading technology and productivity to Hemlo in support of Barrick’s goal to modernise and improve the performance of the mine and establish it as a Tier Two asset within its group”.
