BHP is the first customer to announce plans to trial Caterpillar Inc.’s Cat® Dynamic Energy Transfer (DET) system on battery electric and diesel electric mining trucks at BHP sites.

Caterpillar announced the launch of the Cat DET solution last week ahead of displaying a Cat 798 AC with a DET attachment at MINExpo 2024, this week. The technology can transfer energy to both diesel-electric and battery-electric large mining trucks while they are working around a mine site. It can also charge an electric haul truck’s batteries while the machine is on the move, and the system’s infrastructure is flexible, which allows it to be easily relocated when compared with current commercialised offerings, including large, fixed overhead trolleys.

The planned trials are the result of over two years of close collaboration between BHP and Caterpillar to find sustainable and viable energy transfer solutions. The trials include validating the solution in BHP Iron ore and Copper businesses, including CAT 793 fleet at Jimblebar and CAT 798 fleet at Escondida. BHP also intends to trial Cat DET as an integrated system with Cat autonomous solutions.

BHP announced in 2021 a collaboration with Caterpillar to deploy zero-exhaust emissions mining trucks at BHP sites to reduce operational greenhouse gas (GHG) emissions, enabling more hands-on learning opportunities to ensure successful deployment at BHP sites. The collaboration has helped shape the processes, technology and infrastructure that will be required to support diesel-electric and battery-electric mining trucks and the mine sites of the future, the company says.

BHP’s Chief Commercial Officer, Ragnar Udd (right), said: “We are pleased to be able to trial the DET technology that Caterpillar has developed, and it is a welcome addition in our plans to enable zero-emissions mining truck deployment at BHP. Innovation and technology will play a crucial role as we work towards BHP’s goal of net zero operational emissions by 2050, and we are determined to keep building partnerships like this to achieve this objective.

“This collaboration is testament of our commitment to find solutions that are sustainable and viable – for us and the broader industry.”

Denise Johnson (left), Caterpillar Group President, said: “BHP has been part of our Early Learner program from the beginning, providing valuable feedback. We look forward to continuing that collaboration as we work together to trial the Cat DET system on both diesel-electric and battery-electric trucks at BHP’s sites. This is an important next step to validate the crucial energy management solutions needed to support not only BHP and Caterpillar, but also the broader mining industry.”

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.
