First of two Cat 6040 shovels head to Centamin’s Sukari gold mine

Mantrac Egypt says it has completed the assembly, commissioning and handover of a Caterpillar 6040 BH hydraulic shovel to Centamin’s Sukari gold mine in the country.

This is the first of two new excavators heading to the operation.

The Cat dealer said: “With gross power over 2,000 hp (1,491 kW) and approximately 40 t bucket payload, more volume of material will be moved and at lower cost per tonne.”

Back in December, Centamin said it would soon be adding new Cat 6040 hydraulic face shovels to its existing fleet at Sukari. This is part of a plan to position Sukari to reliably produce 450,000-500,000 oz/y of gold at all-in sustaining costs below $900/oz sold from 2024. This has also seen Centamin take on Capital Ltd as open-pit waste mining contractor.

These new shovels are included in the company’s financial year 2021-2023 capital expenditure plans. Also included is a 36 MW solar plant, an explosives contract and the addition of lightweight truck trays.

MACA increases open-pit scale by acquiring Downer EDI’s Mining West business

MACA has entered into a binding agreement to acquire Downer EDI Limited’s Mining West business in a deal that could involve a consideration of A$175 million ($132 million).

Just last week, MACA said it was considering the potential purchase of Downer EDI Limited’s Mining West division as part of a stated plan to explore and pursue growth opportunities that will deliver “value to shareholders on an ongoing basis”.

The Mining West business currently comprises four large contracts at the long-life assets of Karara (Ansteel), Eliwana (Fortescue Metals Group), Cape Preston (CITIC Pacific) and Gruyere (Gold Fields, Gold Road Resources).

MACA’s CEO and Managing Director, Mike Sutton, said the acquisition provided MACA with a very meaningful addition of a large-scale mining fleet currently engaged across these projects. This comprises 14 excavators and shovels, 65 dump trucks, 11 surface drills and 36 other ancillary machines.

The fleet being acquired is currently fully utilised, or in the process of being deployed to projects, with the equipment having mixed life (with machines being on average mid-life). MACA says its due diligence has confirmed the machines are in good working order, having been well maintained by Mining West’s internal plant department.

With the inclusion of Mining West, MACA now has total contracted work in hand of over A$3.4 billion, which provides a robust revenue base well past its 2025 financial year, Sutton added.

MineWare takes Argus to new heights at Chile copper mine

MineWare says it has recently completed its first high-altitude installation of its Argus monitoring system at one of Chile’s largest copper mines.

While technology continues to digitise and automate many mining processes – with the company recently helping a major copper mine in Chile set up its Argus and Pegasys monitoring systems on five of its electric rope shovels without stepping foot on site – there are still some tasks that need to be managed on the ground, it says.

Reflecting on a recent installation of MineWare’s Argus monitoring system on a P&H 4100XPC shovel at this large copper mine in Chile, MineWare’s Vice President for South America, Ramiro Mesina, said his team specialise in adapting and responding to clients’ environmental conditions.

“We pride ourselves on understanding the unique challenges and opportunities at each of our clients’ sites,” he said. “Our technology has been developed to support this and our team are well-versed in solving complex problems.

“Our recent work in Chile saw our team manage an installation of our Argus monitoring system at an altitude of 4,800 m above sea level in -10°C temperatures with occasional earthquakes: definitely not your every-day situation.

“While this was our first high-altitude installation, the process and care our team puts into planning this type of operation is tried and tested. Efficient project management and coordination, led by our Regional Operations Manager, Hector Mendoza, was key to ensuring a successful installation as well as the safety of all involved.”

In addition to the location of the mining site, the MineWare team also needed to manage this process during a global pandemic. Mining sites in South America have continued to operate throughout the COVID-19 situation, however for many this has been at a reduced level or with a skeleton staff.

Mesina said the strict COVID-19 regulations put in place to protect worker’s health and safety meant there was also minimal on-site assistance to support MineWare’s installation process.

“This was another factor we needed to address in our planning,” he said. “We knew we needed to reconsider logistics as there would be challenges with making resources and vehicles available.

“We determined that the most efficient process would be to add additional time to our preparation on-site and run the installation over four night shifts. This allowed our team to identify any other issues prior to the installation while taking into consideration the potential impact of the altitude on our team.”

Mesina said the team successfully completed the installation on schedule, with only a couple of small earthquakes halting the progress on-site.

Argus is an advanced monitoring system for electric shovels, hydraulic excavators and wheel loaders.

The interoperable solution captures and shares valuable operating data to on site and remote mining personnel in real time to optimise payload performance, mine compliance and machine health, according to the company.

MineWare goes remote for latest Argus and Pegasys deployments

MineWare has been ramping up its remote deployment offering during these challenging times, with the Komatsu-owned company’s local teams recently helping a major copper mine in Chile set up its Argus monitoring system on five of its electric rope shovels without stepping foot on site.

The company is focused on helping its customers stay operational and keep safe during the COVID-19 pandemic, and CEO, Jason Fisher, said the company’s ability to adapt and innovate had proven key to finding new and different ways to meet customers’ needs in the field given numerous virus-related constraints.

“Remote monitoring, service and support is a fundamental part of our business. It’s what we know and what we do best,” he said.

“During the pandemic, we’ve pushed the boundaries of these capabilities to help our customers protect their workforce while continuing to drive forward productivity and efficiency.

“Our local field support teams around the world have transitioned to deliver more services remotely, thinking outside the box to perform tasks traditionally delivered on the ground, like the deployment of new systems.”

Fisher said innovation, collaboration and communication have been critical success factors in helping customers adapt to the changing environment.

Referencing the Argus deployment at the Chile copper mine, he said: “Calibrating multiple systems, for the first time virtually, was a historic achievement, made possible by the collective efforts of our remote teams working in close partnership with customer teams in the field.”

Argus, an advanced monitoring system for electric and hydraulic loaders, is designed to manage payload, mine compliance, machine health and situational awareness.

The company’s North American team has also recently been successful in completing its first 100% remote Pegasys dragline system calibration, with instruction to and assistance from the customer, Fisher added.

Pegasys is, MineWare says, an advanced payload and mine compliance monitoring system for draglines that enables mine sites to establish best operator practice.

Fisher believes there will be increased demand from the global mining industry for innovative solutions that facilitate greater connections between remote and in-field workers.

“As we start to see many of the large mining companies return to normal rosters, workforce safety and connectedness will drive continued demand for digital technologies and remote service offerings,” he said.

“The industry needs interoperable, OEM-agnostic solutions that improve the flow and visibility of information between equipment, systems and people – to make operations safer, more effective and more productive.”

Cat’s 7495, 7495HF shovels receive an AC drive boost

Caterpillar has updated the AC electric drive system for Cat® 7495 and 7495 HF electric rope shovels to, it says, deliver even greater reliability, improved maintenance access, enhanced safety and expanded ability to perform at high altitudes and in extreme temperatures.

The updated system also is designed to easily integrate with advanced technologies.

Caterpillar and our predecessor in shovel design and manufacturing, Bucyrus, have supplied more than 300 AC electric rope shovels, said Dale Blyth, Product Manager, Electric Rope Shovels. The most recent advances in AC drives are integrated in this update and demonstrate how we apply our experience to help customers lower cost per tonne and bolster safety.

Updates include a liquid-cooled motion regulator cabinet for more efficient dissipation of heat generated by electrical components.

The company said: “The new system enables shovels to operate at temperatures of -40 degrees C/F to +50 degrees C (122 degrees F) and altitudes of 5,250 m (17,220 ft) without derating.

“The reliable system also eliminates airborne contaminants in the cabinet and lengthens service intervals – for reduced costs and greater uptime. Additionally, a new, faster propel transferswitch cuts lag time by 75% for improved productivity.” 

New technologies enable consolidating two cabinets in the machinery house to create space for easier maintenance access, while the updated maintenance station is designed for integration of current and future technology solutions, including Cat MineStar.

The drive system design uses common motors in multiple applications, according to Cat. “That means fewer parts to stock, improved parts availability and simplified maintenance.” 

The new motors also have higher power densities, smaller frame sizes and optimised footprint, which aids access, it added.

The Cat rope shovel electric drive system still features elements such as fuseless insulated-gate bipolar transistor modules. And, the on-board maintenance station continues to aid technicians in identifying faults and resolving issues.

The new electric drive system will be on all new production 7495 and 7495 HF shovels beginning in late 2020.

The system is not intended for retrofit, though some elements, such as the fast propel transfer switch, are available as upgrades to machines already in service, according to Cat.
