Cat to use NMG’s Matawinie graphite mine as ‘zero-emission machine’ testbed
Nouveau Monde Graphite and Caterpillar have signed an agreement pursuant to which Caterpillar will develop, test and produce Cat® “zero-emission machines” for the Matawinie graphite mine, in Quebec, Canada, with a view to becoming the exclusive supplier of an all-electric mining fleet for deployment at the mine by 2028.
Looking to accelerate and tailor the equipment development, Caterpillar will engage with Nouveau Monde’s team to incorporate “voice of customer” throughout the development, and for testing of the zero-emission fleet and infrastructure prior to commercial production, the companies said.
To this point, Caterpillar has only disclosed the development of a battery-electric 15 t LHD, the R1700 XE, however it came to light just over a year ago that the OEM was working on a separate project called ‘Project Verde’.
Brian Weller, Chief Engineer, Surface Mining & Technology, Caterpillar Inc, previously stated on Project Verde: “Caterpillar has responded to customers by launching a project that is focused on energy and emissions reduction, and helping customers decrease their carbon footprints through machinery and power solutions that contribute to lower greenhouse gas.”
Speaking about the latest agreement between NMG and Cat, Arne H Frandsen, Chairman of Nouveau Monde, commented: “I recall our first meeting with Caterpillar some two years ago, outlining our vision of a zero-emission mine in Québec. Our commitment to this vision has taken us to this very important moment, not only for Nouveau Monde, but for the global mining industry as a whole. Today, alongside Caterpillar, which in my opinion is the most trusted and reputable supplier of heavy-mining equipment worldwide, we can bring the zero-emission machines vision into reality.
“I think it is remarkable that Nouveau Monde, as a representative for the new style green resources industry, is part of spearheading the electrification of the industry, by collaborating with Caterpillar.”
Eric Desaulniers, Founder, President and CEO of Nouveau Monde, added: “We are proud to be a driving force for our peers as we strive to electrify our operations to meet our carbon neutrality commitments while maintaining the productivity and efficiency standards of our mining operations. Even more gratifying and important to our corporate mission is that our project can serve as a springboard for the future of the mining industry by collaborating with Caterpillar on these cutting-edge technologies.”
Denise Johnson, Caterpillar Group President, said: “The collaboration between Caterpillar and Nouveau Monde marks an important milestone in the mining industry. Through integrated technology, machines and services, the entire Caterpillar team is proud to support Nouveau Monde as they work towards constructing and establishing their first zero-emission mine.”
In November last year, NMG issued an “international call for pre-qualification” related to the fleet and charging infrastructure at Matawinie following work by the company’s International Task Force Committee. This work had allowed Nouveau Monde to explore “technologies, best practices and operational parameters to bring its vision to life in a cost-effective and technologically advanced way”.
As part of this pre-qualification program, companies were able to submit detailed proposals and performance specifications from their production equipment solutions between November 30 and January 30, 2021.
In the 2018 definitive feasibility study on Matawinie, Medatech Engineering Services Ltd and ABB Inc – both companies in Nouveau Monde’s taskforce committee – came up with the fleet outline at Matawinie.
“The mine will be using an all-electric, zero-emission mine fleet, consisting of electric battery-driven 36.3-t mining trucks, battery-driven front-end loaders, cable reel excavators and bulldozers, and battery-driven service vehicles,” the report read.
The mine, scheduled to produce 100,000 t/y of graphite concentrate, was also expected to use an electric in-pit mobile crusher and overland conveyor system to feed crushed material to the plant.
