Sudbury: Going deeper will mean mining longer in Sudbury, Ont. (CBC News Sudbury – January 2, 2023)

The Onaping Depth project will be 2,500 metres below the existing Craig Mine

To extend its Sudbury, Ont., mining operations to 2040, Glencore plans to go very deep underground. The mining giant expects its $1.3-billion Onaping Depth project to be fully operational by 2025.

The new mine is being built around 2,500 metres below the former Craig Mine, which shut down in 2009.

Peter Xavier, vice-president of the company’s Sudbury operations, said without Onaping Depth, they would eventually run out of feed material, or ore, from the Sudbury area for their smelter.

Extending a mine’s life

“As our mines are coming towards end of life, the metal production they’re producing as the grades drop is less,” he said. “You know it’s the same amount of work to get that tonne of ore. There’s just less metal in it.”
