Autonomous equipment commissioning ramps up at Côté gold project

IAMGOLD has released its latest quarterly results, highlighting the significant progress it has made on its majority-owned Côté gold project in northeastern Ontario, Canada.

The company is the majority owner and operator of Côté, with the next biggest stake owned by Sumitomo Metal Mining. Côté has a mine life of 18 years, and will produce an average of 365,000 oz/y over this term. Some 236 Mt of ore will be mined, along with 568 Mt of waste, with an average processed grade of 0.96 g/t Au.

In the latest results, IAMGOLD said the project was estimated to be 85.7% complete as of the end of June. Since commencement of construction, $2.23 billion ($1.56 billion at the 70% held by IAMGOLD) of the planned $2.965 billion ($2.08 billion at 70%) of project expenditure has been incurred.

Autonomous operations have been incorporated into the Côté mine design with a focus on early operations readiness. The Autonomous Control Room equipped for Caterpillar Command for hauling was completed in mid-September and the project achieved a major milestone in January with the initial deployment of the autonomous 231 t Cat 793F CMD haul trucks working with Toromont Cat. On January 22, the mine saw the safe operation of a full load, haul, and dump cycle using autonomous dump trucks.

During the June quarter 2023, up to seven Cat 793F haul trucks have begun operating in autonomous mode and a total of 14 haul trucks have been commissioned. Autonomous drilling with two Epiroc Pit Vipers began in this quarter, with a third nearing commissioning completion. In total, the company is expected to operate six autonomous Epiroc Pit Viper 231 blasthole drill rigs, complemented by two Epiroc D65 SmartROC crawler rigs, which will be remote operation ready.

In addition it will deploy electric Caterpillar hydraulic shovels – namely two 6060FS units, AC-powered via tethered cable.

The company said owner mining has progressed well with nearly 1.1 Mt mined in the June quarter. The stockpile has approximately 2 Mt of material on track to the target build-up of 5 Mt by the end of the year. The IAMGOLD mine operations team started operating 24/7 effectively in July.

The project timeline remains in place, with production expected to commence in early 2024.

Bingham Canyon to become first Rio Tinto site equipped with Cat MineStar Fleet

The Bingham Canyon copper mine in Utah, USA, has selected the Cat® MineStar™ Fleet management system as part of its plans to optimise open pit operations at the mine, owned by Rio Tinto, Caterpillar says.

Caterpillar Inc and Wheeler Machinery recently completed installation of a Cat MineStar Fleet management system at the mine, which, rather than upgrading the mine’s previous fleet management system, chose to deploy MineStar Fleet. This switch has, Caterpillar says, optimised the mine site’s equipment tracking, production recording, material management and truck assignment, and it has further expanded the technology relationship between Caterpillar and Rio Tinto.

Ryan Howell, Mining Technology Commercial Product Manager at Caterpillar, said: “For 15 years, Rio Tinto has used MineStar Terrain and has expanded its MineStar capabilities in recent years at locations like Gudai Darri and Marandoo, autonomous mine sites in Western Australia. Bingham Canyon Mine is the first MineStar Fleet site in Rio Tinto history, and this extends the company’s application of MineStar capabilities. Our team is proud of this MineStar Fleet system installation. We are honoured to be there to support the mine site’s fleet management needs.”

Joshua Wood, Principal Advisor, Surface Mining Centre of Excellence at Rio Tinto, added: “The close collaboration between the Rio Tinto Group team, Caterpillar, dealer and Kennecott ensured a successful deployment at Kennecott and their desire to be the flagship for future MineStar sites.”

Even though it wasn’t the easiest route for the mine, the cost-benefit analysis showed significant benefits long term using MineStar Fleet, including seamless integration with MineStar Terrain currently used by the mine, Caterpillar said.

Mike Gray, General Manager for Wheeler Machinery, said: “A true partnership with the supplier, dealer and customer allows for large-scale technology projects like this to be completed successfully with minimal impact to production.”

An incremental approach was devised to minimise the system installation loss-time impact on mining operations for bringing nearly 100 trucks, plus more than 40 supporting dozers, shovels and drills, online with MineStar Fleet. Caterpillar and Wheeler worked together to provide a quick turn-around time with best-in-class implementation, Caterpillar said.

Bryce Olson, Mine Monitoring and Control Superintendent at the Kennecott Bingham Canyon Mine, said: “We have been impressed with the partnership, and we share the same vision and have the correct team to get us there. We flipped the switch, and we haven’t gone backwards. We immediately started using MineStar Fleet’s open assignment, load-haul-dump and auto fuel advanced features.”

Cat MineStar Fleet automatically records and tracks data up and down a mine’s value chain, providing insights that help miners identify what is working and fix what is not to meet production targets, Caterpillar says. Fleet allows miners to view the entire operation at a glance on a computer and gain insights into key cost drivers – such as fuel, tyres, service parts and idle time – and improve haul fleet production and shovel utilisation.

Caterpillar boosts payload, performance with new 995 wheel loader

Building on the success of the 994K, the new Cat® 995 Wheel Loader features up to 19% increased productivity than the previous model with its higher rated payload and 6% increase in hydraulic force with equal hydraulic cycle time, Caterpillar says.

This new loader delivers up to 13% lower hourly fuel consumption and offers up to an additional 8% efficiency gain when operating in Enhanced Eco Mode compared with throttle lock mode, according to the company. It is also up to 19% more efficient than the 994K in equal comparisons of throttle lock operation.

Enhancements to the front linkage include an improved casting design, increased weld size, larger bearings and pins, and profile changes for increased service life. New, larger capacity buckets available for the 995 incorporate an extended floor for fast loading, high fill factors reaching 115%, and excellent material retention. Buckets are interchangeable between the 995 and 994K.  

Built to the same size as the 994K but offering a higher rated payload, the new 995 enables a one-pass reduction when loading Cat 785, 789 and 793 mining trucks. This equates to up to a 33% increase in production and efficiency when loading the 785, up to a 25% increase with the 789 and up to a 20% increase with the 793.

The new 995 meets the global industry’s demand for high production and greater payloads with its powerful Cat 3516E engine offering configurations based on regional needs, meeting EU Stage V/US EPA Tier 4 Final or US EPA Tier 1 equivalent emissions, the company says. Its 39% torque rise ensures high lugging forces during digging and acceleration in high rim pull conditions.

Comfort and visibility

The redesigned next generation operator environment for the new 995 has 50% more legroom and boasts features that improve operator confidence while reducing fatigue. Its pressurised cab reduces vibration feedback, lowers sound levels and includes automatic temperature control. Providing shift-long comfort, its new electro hydraulic speed-sensing steering with force feedback automatically stiffens when traveling at higher speeds and softens as speed decreases to boost operator confidence.

Designed for visibility, the cab’s taller windshield provides a 25% increase in glass surface area and a 64% increase in wiper sweep area to better see the bucket. Two 254-mm colour LED monitors display machine control, operating functions and the electronic operator’s manual. A third 203-mm screen offers a dedicated view of the standard rearview camera and is upgradable to a multi-view camera system that offers 270° vision with rear object detection.

Access and egress to the cab along with all service areas being accessed from either ground level or a platform improves safety on the job. Wide stairs with full handrails on each side are positioned at a 45° angle for easy access. An optional powered access system – raised and lowered from either the cab or ground level enhances ingress and egress to and from the rear platform even further.

Confidence-boosting technology

Integrated with electronics, the new Cat 995 wheel loader offers flexible levels of information and technologies for a smart machine and more informed operator, maximising the productivity of both. Standard tip up prevention technology avoids unnecessary stress on the drivetrain and structural components by delivering full breakout forces while preventing the back tyres from significantly lifting off the ground.

New optional Autodig components automate three of the dig cycle’s most difficult parts in both rehandling and tough digging applications to improve productivity and reduce tyre wear.

Reducing tyre wear, Tire Slip Prevention reduces rimpull before the tyres are set and increases rimpull when downward force is applied. Auto Set Tires detects pile contact and automatically lifts against the pile to set the tyres and increase available traction, discouraging premature racking. Lift Stall Prevention manages rimpull in-dig to prevent hydraulic stall when lifting through the face, so the 995 spends less time in the pile.

An onboard interactive training tool, optional Operator Coaching measures and reports on individual operator behaviours that have an impact on efficiency, production and component life. Instructional videos provide training on measured behaviours, showing both the incorrect and recommended behaviours. Among 21 total monitored operating technique aspects, the system shows how to properly reduce tire rotation, avoid unracking in-dig, enter the pile with a level bucket, avoid excessive usages of the impeller clutch, reduce dump height and use the kick out.

Available Payload Overload Prevention improves productivity and efficiency by allowing a larger bucket to be used to achieve pass-match targets across a range of material densities without risk of overload. It is configurable to either stop or slow lift arms when the maximum allowed payload, including bucket weight, is exceeded.

Standard Vital Information Management System (VIMS) on the new 995 allows customers to connect directly to the machine to access a wide range of sensor information and enhanced machine data. Taking the guesswork out of asset management, standard Cat Product Link™ provides remote access to machine operating data via the easy-to-use VisionLink® interface. The 995 supports a variety of Cat MineStar™ solutions including Health, Guide and Terrain.

Reduced maintenance

Offering a 500-hour engine oil change interval and improved air filter life, the 995 spends more time working. The number of steering hoses has been reduced from 15 to 10 and tubes cut from 11 to one to improve steering system reliability. An enhanced service station provides access to functions like coolant and oil as well as level indicators, and it features a Cat battery charging connector and indicator lights for fuel tanks.

The loader’s redesigned pump bay improves access to transmission components, offers discharge ports on the side of the pumps and has simplified lines routed directly to the high-pressure screens. The bay includes a brake pump filter, implement pilot filter and implement discharge screens, and diagnostic ports are accessible from the front walk deck and pump bay. Ground line service now includes a steering pilot filter, transmission filters and steering pump discharge screen.

Caterpillar boosts payload and speed with lower-emission R2900 XE LHD

The first diesel electric underground load-haul-dump (LHD) loader from Caterpillar, the new Cat® R2900 XE LHD, has officially been launched with a goal of meeting the underground mining industry’s needs for bigger payloads, faster loading and reduced emissions.

Built on the platform of Caterpillar’s most popular underground loader, this new LHD – which was previewed at MINExpo 2021 in Las Vegas – features optimised lift arm and component geometry plus load-sensing hydraulics to improve breakout force by 35% over the Cat R2900G, the company claims.

The world’s first R2900 XE has already been delivered to Western Australia-based gold miner Westgold Resources.

The R2900 XE works faster in tough conditions, delivering 52% quicker acceleration and improved machine response over the R2900G. It accelerates from 0-24 km/h in 6.4 seconds and achieves a 7% higher speed on grade, according to Caterpillar. Variable piston pumps deliver higher flow rates for faster hydraulic cylinder cycle times and powerful lift forces. Boasting a higher, 18.5-t payload for faster load times, the new LHD model offers a 3- to 4-pass match to the Cat AD63 truck for greater efficiency. Combined, these features deliver a 20% increase in productivity for the R2900 XE, Caterpillar says.

The loader’s redesigned buckets are available in four sizes with capacities ranging from 7.4 to 9.8 cu.m to match material density needs for a variety of loading, hauling and dumping conditions. Offering an optimised balance between productivity and bucket life, the full range of Cat ground engaging tools (GET) includes Modular Weld-on, Bolt-on Half Arrow and Durilock™ mechanically attached shrouds. To further protect the bucket, a range of heel shrouds, wear plates and bars are available in weld-on or mechanically attached designs.

The Cat C15 engine on board offers a variety of emission reduction and aftertreatment options, including an EU Stage V/US EPA Tier 4 Final configuration and diesel particulate filter. It delivers the power needed – up to 335 kW – with greater than 31% increased fuel efficiency compared with the R2900G. Its lower engine revolutions per minute results in reduced fuel burn, heat, noise, vibration and exhaust emissions, while offering an increase in power and productivity, according to Caterpillar.

High-efficiency electric drive

Drawing from decades of experience, the new R2900 XE LHD features a switch reluctance electric drive system. It is Caterpillar designed, integrated, validated and supported, and its continuously variable speed control delivers improved power and cycle times, Caterpillar says. With no driveline or powertrain shock loads, it offers smoother directional changing and implemented virtual gears for machine controllability. Automatic retarding controls maintain speed on grade. The drive system prevents coasting in neutral and combines with the anti-rollback feature to further increase operating safety.

Its new axle design offers increased component size and, together with the four-gear planetary final drive groups, provides greater strength and longer life. Larger wheel bearings and increased brake sizing further increase final drive life. Flange-mounted rims allow for safer tyre and rim changes. The differentials and final drives are built to withstand the forces of high torque and impact loads, providing high torque multiplication to reduce drivetrain stress. The traction control system, meanwhile, reduces tyre spin in difficult underfoot conditions to improve productivity, increase tyre life and reduce consumable costs.

The operator environment is built on Caterpillar’s R1700 platform, incorporating the latest improvements in productivity, safety and comfort. The cab’s enclosed design provides fresh, pressurised, temperature-controlled air circulation with air conditioning to enhance operator comfort and decrease fatigue. Resiliently mounted to the frame, the ROPS/FOPS structures isolate the operator from vibration for a more comfortable ride. The cab design incorporates two emergency exits, while available rearview and forward- and rear-facing side-view cameras help to improve visibility around the machine to enhance safety for operators and other workers.

Combining selection of direction, virtual gears and steering into a single lever, the standard STIC™ steering and transmission integrated control delivers maximum responsiveness and machine control, Caterpillar says. Low-effort, electric-over-hydraulic joystick controls feature simultaneous lift and tilt functions to optimise operating efficiency, while a two-pedal design with improved spacing and position facilitates more efficient foot control.

Caterpillar adds that the optional ride control improves cycle times and load retention when operating in rough terrain. By engaging/disengaging the ride control system at preset speeds, the system automatically dampens bucket forces and stabilises the machine, reducing fore and aft pitching motion. It incorporates a nitrogen/oil accumulator system in the lift circuit to act as a shock absorber.

Scalable technology solutions

The new R2900 XE ships from the factory equipped ready for Cat MineStar™ solutions, a comprehensive suite of technology offerings. From machine health monitoring to fully automated haul and dump cycles, scalable levels of technologies can be tailored to meet each mine site’s unique needs, Caterpillar says. Standard Product Link™ Elite boosts machine connectivity by enabling the loader to collect and transmit health and condition monitoring information into locally or cloud-hosted applications.

Mine sites can choose between a range of available MineStar technologies, including:

  • Command for underground – enables remote operation of LHD machines, from line-of-sight to full autonomy, allowing operators to be relocated to a safe, comfortable location to improve productivity, efficiency and safety;
  • Detect for underground – uses peer-to-peer proximity detection to reduce the risk of unintended interactions between people and machines by “seeing” in the dark;
  • Fleet for underground – gives real-time access to accurate information such as cycle time, payload, machine position, and other key operational parameters and automatically tracks and records data up and down the value chain; and
  • Health – collects and transmits equipment data necessary for proactive maintenance services and predictive equipment analysis.

New Autodig technology optimises loading by automating crucial parts of the digging cycle, Caterpillar says.

“When combined with Command for underground, Autodig offers a true automated machine, providing high-speed auto tramming and full cycle autonomy,” the company explains. “Featuring an onboard payload weight scale, Cat Payload Management provides material management, cycle count and timing recording, and wireless production detail reporting capabilities. Optional tyre pressure monitoring is fully integrated into the R2900 XE, allowing operators to determine on-the-fly if the tyres are properly inflated.”

With more robust structures, increased powertrain durability, longer lasting components, improved maintenance and extended service intervals, the new R2900 XE can be maintained in less time, helping to lower cost-per-tonne operation, Caterpillar says. The machine’s electric drive reduces the number of moving parts compared with traditional mechanical drive systems. Extended oil change intervals, together with the electric drivetrain, reduces the amount of oils used. Sight gauges visible from ground level simplify fluid level checks, and all filters are positioned vertically to provide spill-free servicing, Caterpillar claims. Electrical connectors are sealed to lock out dust and moisture, while harnesses are covered for protection.

Machine design eliminates castings and reduces weight to increase the life and strength of the frame without sacrificing performance. The frame, powertrain, engine and components are built to be rebuilt using new, remanufactured, or rebuilt parts and components, allowing mines to take advantage of multiple lives of like-new performance to lower operating costs.

Agnico Eagle’s Detour Lake mine adds Cat 798 haul trucks to fleet

With the aim of ramping up production at the Detour Lake gold mine in Ontario, Canada, Agnico Eagle Mines has commissioned four Cat® 798 AC haul trucks at the open-pit operation.

These trucks, which come with a 372-t payload and are electric drive, were introduced to the market in 2019, joining the mechanical-drive Cat 797F in the 400-short-ton size class.

Agnico said these new vehicles were introduced to the fleet in the March quarter, with an additional two units planned to be commissioned in the June quarter.

In the March quarter of 2023, the Detour Lake mill set a record for first quarter throughput and activities continued to focus on mill process optimisation and improving availability with the goal of achieving and potentially exceeding throughput of 28 Mt/y. This helped the company produce 161,857 oz of gold in the three-month period.

While the company’s near-term focus is on open-pit operations at the mine, it is also looking to integrate additional drill data into a revised mineral resource model that will be used to evaluate potential underground mining scenarios.

The population of Cat 798 AC trucks has been growing in the last few years, with the Antamina, Toquepala and Cuajone copper mines in Peru. Last year, Finning announced it would deliver 13 Caterpillar 798s to Codelco’s Ministro Hales open-pit copper mine, while BHP, Caterpillar and Finning International announced, in August, that a haul truck fleet replacement process at the Escondida mine, the world’s largest copper producer, would also the OEM and dealer provide Cat 798s to the operation.

Caterpillar, Barloworld, AMS and Sandfire collaborate at Motheo in Botswana

When Sandfire Resources produces the first ore from its new Motheo copper mine in Botswana, southern Africa, later this year, the company will officially be on its way to developing a long-life copper production hub in the central portion of the Kalahari Copper Belt of Botswana and Namibia.

That first ore from Motheo is just the beginning of the company’s long-term growth plans in the region. Before the development of the mine was even completed, Sandfire had already announced plans to enlarge the operation by exploiting an additional deposit and building an expanded processing plant to handle production.

Recognizing the potential of the Kalahari Copper Belt, Sandfire and its chosen operations partner for Motheo — Perenti Group’s African Mining Services (AMS) — made a commitment to the highest standards of productivity, safety, responsibility and sustainability.

A critical contributor to meeting that commitment will be the use of mining technology. And key partners in that effort will be Caterpillar and Cat® dealer Barloworld Equipment, who are working with Perenti/AMS to provide a suite of technology solutions that will deliver innovation to the mining operation.

Crew with mining truck

“We know that Sandfire Resources, our customer Perenti, and the entire team at Motheo is committed to using technology to build the safest, most productive operation possible,” Nathan Wescombe, a Senior Account Manager at Caterpillar, said. “We’re proud that Perenti has chosen Cat technologies to help them become the operator of choice within the region and deliver innovation to their mining practices.”

To ensure the successful deployment of technology in an area of the world where mining technology is not the norm, Caterpillar conducted a three-day information-gathering and change management workshop to consult with key stakeholders to help ensure they are technology-ready.

“Change management is a key to the implementation of technology in any operation,” Leslie Fengu, a Senior Regional representative for Caterpillar’s Mining Technology Solutions division, said. “And it’s even more critical in an area where it’s being introduced for the first time. Fortunately, Caterpillar has a team that has plenty of experience in helping our customers manage this change – understanding the challenges, developing possible solutions to address them, and providing ongoing support through implementation and beyond.”

Held in August 2022, the workshop was very well attended, met with positive feedback, provided critical knowledge of the operation, and identified opportunities moving forward to ensure success for all stakeholders, according to Caterpillar.

Greg Lawson, a General Manager at Perenti/AMS, said: “Incorporating technology into our operations is an important piece of our global strategy. Having the support of Caterpillar and Barloworld as we implement these solutions in a new region is proving to be instrumental in helping us realise our goals. We appreciate the value of their expertise not only in the technology itself but also in addressing the significant change management that goes along with its implementation.”

The Motheo copper mine

Motheo Copper Mine is located in the Kalahari Copper Belt, a major zone of strata-bound copper-silver deposits extending for 1,000 km along the northern margin of the Kalahari Craton in Namibia and Botswana.

The greenfield project is being developed by owner Sandfire Resources, an Australia-based mining and exploration company with a global presence. Open-pit mining services are provided by contractor AMS, the Africa-based surface mining arm of Perenti Group, a global mining services company also based in Australia.

Motheo represents the foundation for Sandfire’s long-term growth plans in Botswana and is expected to generate approximately 1,000 jobs during construction and 600 full-time jobs when fully operational.

After a positive feasibility study in December 2020, Sandfire’s board approved the development of Motheo. The feasibility study identified a robust initial 12.5-year operation with annual production of high-quality copper concentrate estimated at 3.2 Mt. Site construction commenced in 2021, with first production scheduled for mid-2023.

The Motheo Copper Mine will be based on an open-pit operation for the original deposit, identified as T3. The drill-and-blast operation will focus on 10-m benches, using suitable blasting methods to minimise dilution. Trucks will be loaded by 250-t excavators. Direct run-of-mine ore will be delivered directly to the crusher or placed on stockpiles for future rehandling.

AMS selected a fleet of Cat trucks to handle hauling duties, supported by a variety of other Cat machines. Barloworld recently delivered 20 139 t Cat 785 trucks, four D10T dozers, two 777 water trucks and two 18 motor graders to the mine.

Beyond the quality expected from the Cat machines, a major factor in the equipment purchase was related to the Cat MineStar™ technology products that accompany them. AMS, Caterpillar says, selected three separate but integrated solutions that will impact the efficiency and production of the operation, the uptime of machines and the safety of its people:

  • MineStar Edge™, a cloud-based equipment management and production recording platform that provides access to highly accurate production data and gives visibility to the entire mining operation;
  • Health – Equipment insights, a user-friendly data visualisation and reporting tool that allows sites to easily access, view and analyse machine health information and gain insights to help reduce unplanned downtime and prevent failures; and
  • Cat Driver Safety System, an in-cab detection technology that can help sites identify operator fatigue and distraction and address it in real time.

Introducing technology in Botswana

Sandfire and Perenti are no strangers to mining technology. Sandfire’s DeGrussa copper-gold mine in Australia was an early adopter of autonomous mining, using Cat MineStar Command for underground to automate a fleet of underground loaders. The Perenti Group, too, recognises the value of technology in mining, and has added a dedicated services and products business to its portfolio to provide technology and consulting services to the mining industry.

But bringing a technology mindset to this region is not business as usual. For Caterpillar, this is just the third such implementation in southern Africa and the first in Botswana. Cross-departmental interconnectedness is paramount for Perenti and AMS to realise its return on investment as the Motheo team strives to deliver on business demands, Fengu, whose knowledge of the region and its history are extremely valuable to technology implementation in Botswana, said.

“Disruptive technologies, such as those chosen by AMS, require a site-wide approach to achieve successful implementation and sustainable operations,” he said. “Supervisors and their teams are required to effectively manage the implementation and functional changes that will be required with technology, adapting staffed conventional mining techniques to get the most value out of the new mining system.”

To ensure the success of these systems in a country where they have not operated previously, Caterpillar identified an opportunity to leverage the knowledge and capability of its Cat Solutions & Services team, as well as other Cat and Barloworld technology experts. The initiative was led by Caterpillar Technology Change Enablement Manager, Brett Haskins, working with Joel Patterson and Jenny Krasny as key consultants.

“We organised a workshop to develop a deeper understanding of how we could assist in this change, walk through opportunities to help them become more comfortable with the technology and better appreciate how it can help support their roles in the operation,” Wescombe said.

Understanding the site and its culture

This workshop included site observations, interviews, education and facilitated discussions designed to understand the current culture – with a lens toward building operational readiness to capitalise upon the benefits that MineStar Solutions can provide.

The visit occurred over three days with a high level of engagement from every area and level of the deployment. The visit was designed to maximise exposure to the day-to-day goings-on in the operation. Pit operations, departmental interactions and daily activities were observed to determine site mining practices, with a view to assess site readiness to apply MineStar and take advantage of the offerings.

“Understanding the history of change in all organisations was an important part of the workshop and visit,” Wescombe said. “We wanted to learn about change that had been managed well and identify areas for improvement. We did that by asking a lot of questions of people from every aspect of the operation. We engaged the site at all levels – from equipment operators to a representative from Perenti’s office in Perth, Australia.”

The discussions invited participants to share concerns or perceived challenges surrounding daily operations. They were encouraged to contribute ideas around how the daily operation and a change to the site’s mining system can be effectively managed from their perspective.

Workplace culture was also explored, gaining insight into how the site is managed and identifying areas of success and opportunities for improvement. Fengu said: “The goal of this effort was to help reduce incidents and unintended operational consequences, and to provide guidance to remedy any shortcomings through application of the technology.”

In addition, the workshop was designed to strengthen the collaborative relationship between the site, corporate office, Barloworld and Caterpillar. Caterpillar says it and its dealer are essential stakeholders who are pivotal to the successful deployment of MineStar Solutions.

“In a nutshell, our goal was to best understand how we could support AMS through the process of change management,” Patterson, Caterpillar Operational Readiness Consultant, said. “We started by encouraging all participants to leave preconceived ideas at the door on the way in to the workshop and asking everyone to be open-minded to change.”

Developing a path forward

All stakeholders agree that the workshop is just the beginning of ongoing engagement into getting the maximum value from technology at Motheo.

“The workshop helped us start the process,” Sam Farhand, Group Asset Manager for Perenti, said. “We learned a lot about the site and about each other. But now the hard work begins – addressing those challenges we’ve identified and ensuring that we never stop paying attention to how the technology is being used and continuing to find new ways to reap the benefits it delivers.”

An important outcome of the workshop is a 30-plus-page report that identifies the areas impacting successful implementation of MineStar technologies at Motheo and provides recommendations and possible solutions that will help address them.

The report is designed to:

  • Ensure understanding of the “why” for change management, and the benefits of using the Caterpillar team for this initiative;
  • Summarise the vision for the deployment as voiced by Perenti and AMS employees;
  • Articulate the landscape in which the project is taking place;
  • Highlight activities on which to partner or reinforce;
  • Present identified opportunities to adapt, build and embed new processes;
  • Identify the unique needs of the people who will be impacted;
  • Outline a change management plan to support the deployment; and
  • Share immediate action items to facilitate a successful deployment.

Sharing positive feedback

When asked about the success of the workshop, all stakeholders had positive things to say.

“The on-site engagement and participation in the workshop were outstanding,” Pierre Hill, Country Manager for Barloworld Botswana, said. “Attendance was terrific. It was a fantastic example of collaboration and teamwork.”

Wescombe agreed: “We were very pleased with the willingness of the key stakeholders to break traditional silos, open up lines of communication and actively engage in rich discussions between corporate, dealer, OEM, maintenance, planning and operations.”

But the most important feedback comes from Perenti. “We thought the workshop was very beneficial,” Farhand said. “It has helped us build a strong foundation on which to base our focus on innovation and technology.”

As the Caterpillar Manager for Perenti, Wescombe is quick to point out the teamwork and collaboration necessary for the success of the workshop – and the future of the technology in the years ahead.

“Without Greg Lawson and Sam Farhand from Perenti, this event would not have happened,” he said. “They helped us gain the traction we needed from internal stakeholders to get this off the ground. Plus, Sam and the on-site AMS Motheo team were instrumental in coordinating and supporting the workshop to ensure its success.”

“Our Caterpillar and dealer teams also deserve recognition. Leslie Fengu and Joel Patterson were key contributors to this effort, along with Pierre Hill and J.P. Briggs from our Cat dealer Barloworld. These folks worked closely with the Perenti team to build a preliminary understanding of the site challenges in order to optimise discussions during the site visit.”

The collaboration was a great example of the “three-legged stool” Caterpillar talks about when dealing with its customers in partnership with dealers. “When all three entities are working toward the same goal, we’re going to be so much more successful than when we go it alone,” Wescombe said. “We’re looking forward to a lot more opportunities to work together with Perenti/AMS and Barloworld in the years ahead.”

New High-Performance Circle boosts Cat 24 and 24M motor grader performance

Caterpillar’s new High-Performance Circle (HPC) for Cat® 24 and 24M motor graders improves machine performance, efficiency and uptime availability when maintaining haul roads at large mines, according to the manufacturer.

When paired with Cat exclusive extended life blade rail wear strips, the HPC reduces total cost of ownership for the drawbar circle moldboard and downtime by up to 80%, it claims.

Providing a 16,000-hour service life, the new HPC eliminates hours of monthly planned maintenance for frequent inspection, wear strip replacement and circle shoe adjustments associated with conventional circles. Industry-leading machining capabilities designed to tight tolerances help ensure the drawbar, drives and circle perfectly align and require no adjustments for the life of the grader, Caterpillar says.

Cat proprietary heavy-duty planetary gearboxes with integrated forged pinion shaft and gear replace the work drive gearbox and pinion gear system. The gearboxes, meanwhile, have sealed-for-life slip clutches that eliminate adjustments and isolate the clutches from the rest of the drive to increase reliability. Significantly reducing maintenance time, the slip clutch assemblies can be changed out in less than an hour and come adjusted from the factory, according to the company. The brass circle wear strips and shim system is replaced with a sealed roller bearing.

The new fully-sealed roller bearing delivers smooth and effortless blade rotation. Fully integrated with standard machine auto lube, the design eliminates daily greasing and can require no maintenance, adjustment or replacement for 16,000 hours, depending on the application.

A new pinion gear shape with increased shaft diameter for improved durability allows drives to be removed vertically without drive adjustments. And dowel locators precisely position motors for easier servicing, optimal tooth contact and longer pinion life, the company says. Its new design improves component reliability to reduce downtime and maintenance costs.

Caterpillar says: “Beyond lowering total cost of ownership, less required circle maintenance reduces component handling to properly maintain the machine, which improves safety for service technicians. At 16,000 hours, if the circle teeth have reached their wear limit, they can be rotated 180° to double the component’s service life. The new HPC maintains the same machine connection interface, so it is retrofittable to all Cat 24 and 24M Motor Graders.”

Increased power and more robust structures for the new Cat 24 make it an ideal pairing for Caterpillar’s longer 8.5-m moldboard option, the company says. The grader’s new Cat C27 engine, up to 37% increase in torque and new HPC are well equipped to accommodate the blade’s increased weight and width without slowing or bogging down the machine.

At 16% longer than the standard 7.3-m blade, it helps improve safety at larger mines by reducing the amount of time spent in the middle lane to clear the windrow. When used for a wider pass, it brings haul roads back to specification in fewer passes, eliminating one pass when supporting ultra-class trucks, Caterpillar claims. Longer moldboard reach places the windrow farther away from the rear tandems to increase traction. It also allows the operator to use a more aggressive blade angle to reduce machine load, increase speed on passes and help improve material handling.

The 8.5-m moldboard option is retrofittable to existing fleet Cat 24 motor graders. It can be connected to the machine with Cat extended life blade rail wear strips, available for both standard and high-performance circles, to achieve up to three times longer service life than standard rail wear strips.

Anglo Asian bolsters Azerbaijan mining fleet with Epiroc, Cat, Paus and Tunelmak equipment

Anglo Asian Mining says it has placed orders for the major items of equipment required for production from its new Zafar and Gilar mines in Azerbaijan, with a fleet made up of Epiroc drills, Caterpillar loaders and auxiliary machines from the likes of Paus and Tunelmak.

The company has also made progress with the upgrades to its Gedabek flotation plant, it noted.

The equipment for Zafar and Gilar includes an underground fleet from Caterpillar and drilling machinery from Epiroc. The total equipment cost is approximately $10 million, approximately 40% of which will be met from the company’s existing cash reserves with the remaining being funded through vendor financing. The equipment is a significant investment for the company, underpinning its confidence to achieve its stated ambition to transition to mid-tier copper production status, it said.

A day before this announcement, Anglo Asian said it had completed a scoping study for the Zafar underground mine, based on ore production of 700,000 t/y and a 0.5% copper equivalent cutoff grade. Development work and the construction of two portals has also started.

Included in the drilling fleet is an Epiroc Boomer S1 D, three Epiroc T1D jumbos, one Epiroc Simba S7 D and one Epiroc H1354. The Caterpillar machinery includes three 15-t payload R1700 LHDs and two UMA 980 wheel loaders.

Auxiliary units that will complement this fleet include a Paus TSL853 Central articulated steering telescopic swivel loader, two Tunelmak ADROIT 520-2 AH 4×4 hydrostatic basket platforms and one Tunelmak ADROIT 420AH 4×4 articulated hydrostatic shotcrete pump.

Anglo Asian produced 57,618 oz of gold equivalent for the year ended December 31, 2022, but, with the addition of Zafar and Gilar, it has an ambition to become a mid-tier miner producing over 100,000 oz/y of gold equivalent.

An expansion of the flotation plant at Gedabek, the company’s flagship opeation, is underway together with adding a further line to produce zinc concentrate, it said. The total cost of the expansion, which will see it add three new rougher/scavenger cells and four cleaner cells from Maelgwyn Mineral Services, is currently estimated at $3 million which will be paid from the company’s existing cash resources. Contractors have been appointed to supply materials for the new flotation line. Additional contractors will be commissioned to modify the existing building and provide electrical services and control equipment, it added.

The modifications to the flotation plant to increase its capacity have now been broadly completed. The installation of the new flotation line using hydraulic flotation cells will be completed by the end of the year.

Stephen Westhead, Vice President of Anglo Asian, said: “The new equipment will be used to expand the company’s mining and processing operations with the development of two new underground mines this year. The expansion of our flotation plant has been broadly completed, doubling capacity and creating additional processing flexibility. This represents an important step in our medium-term growth ambition to become a mid-tier production miner, and significantly increases our capabilities within copper.”

RCT helps automate dozer push operations at New South Wales tailings op

A well-known mine in New South Wales, Australia, is now operating an autonomous dozer fleet safely and efficiently thanks to the deployment of RCT’s latest solutions, the METS company says.

The technology empowers equipment operators to stand at a safe vantage point overlooking the work zone and direct the dozer fleet to maintain a tailings dam wall on site.

The project means the autonomous dozers can push the top of the tailings dam wall and work close to edges in a way deemed as impossible to achieve safely with operators in the machine’s cab.

Mine management selected RCT’s ControlMaster® solution over global OEM tenders due to the technology’s ability to be repurposed to other mining equipment based on changing fleet demands in the future, RCT, now owned by Epiroc, said.

RCT’s Customer Service team recently mobilised to the site and commissioned ControlMaster onto two Cat D8T dozers and are continuing to support the site on an ongoing basis.

RCT Account Manager, Wayne Carrington, said the project is just the latest in a successful business relationship with the mine which stretches back many years.

“We are very pleased to provide the site with fit-for-purpose technology which safeguards their personnel while enabling them to complete vital works,” he said. “The feedback from site has been very positive with the operators loving the functionality of the solution and management is reporting that they are meeting their targets.

“The ControlMaster technology is vital to the success of this tailings dam project but, in the future, the solution can easily be integrated with any other piece of mining equipment and provide additional benefits to the mine.”
