Glencore Canada reaches shaft milestone at Sudbury's newest, deepest, all-electric mine

This marked a key step toward production ramp-up at the Craig mine and eventual project completion in 2027. First ore from Onaping Depth is expected later this year.

Onaping Depth is part of Glencore's Sudbury Integrated Nickel Operations, with the orebody poised to deliver high-grade nickel and copper ore from almost 2600 m below surface - the deepest that Glencore Canada has dug in Sudbury.

The mine also marks the first new mine to be developed in the Sudbury basin in more than a decade.

Onaping Depth will operate one of the most advanced battery-electric underground mining fleets in the world. The all-electric fleet ranges from the mining equipment that will drill and prepare the mining face and extract, to service and support vehicles moving people, supplies and equipment.

"Eliminating diesel emissions means less ventilation and cooling requirements, which are traditionally among the largest energy demands in underground mining. The use of battery electric vehicles and the benefits they bring is helping to support both Glencore's broader sustainability objectives and Canada's net zero ambitions," says Glencore Canada COO Peter Xavier.

He adds that together with the Craig mine concentrator and smelter, the Onaping Depth project supports the company's long-term presence in the region and strengthens the future of mining in the Sudbury basin.

By extending mining activities to greater depths, Glencore Canada is unlocking new opportunities and resources that will contribute to the continued success of its operations.

Xavier explains that operating at this depth has been made possible through the company's commitment to innovation, including investments in battery electric equipment, remote operations, and automation technologies.

"Reaching these important project milestones is also a testament to the dedication and collaboration of our employees and contractors, who collectively contributed more than nine-million work hours without a lost-time injury. This outstanding safety performance highlights our unwavering commitment to ensuring that every aspect of the project is completed safely."

Almost $2-billion has been invested on the Onaping Depth project since 2019. Once fully operational, the mine will support more than 400 permanent jobs and extend nickel production in the Sudbury Basin beyond 2040.

Canada Environment, Climate Change and Nature Minister Julie Dabrusin says Onaping Depth is poised to strengthen Ontario and Canada's position as leading suppliers of responsibly produced nickel and copper, which are key components in technologies that support electrification, advanced manufacturing and energy security.
