Glencore, Vale approve development of nickel mines in Ontario's Sudbury region

Glencore Plc's board approved a US$700 million investment for the Onaping Depth nickel mine, and Vale SA received approval for a C$760 million investment for its Copper Cliff Deep nickel project, both located in Sudbury, Ontario, the Sudbury Mining Solutions Journal wrote Feb. 21.

The Switzerland-headquartered company, which received development approval in January, is targeting first production from Onaping Depth in 2023, with ramp-up to full production by 2025.

Output from Onaping Depth will replace the Nickel Rim South and Fraser Mines, which are scheduled to end production in 2022 and 2025, respectively.

The company plans to use only electric vehicles at Onaping Depth to save costs on ventilation.

Glencore will also invest US$450 million in its Raglan operation in Quebec and has approved a US$140 million investment to upgrade its Sudbury smelter, the report said.

Meanwhile, Vale will refurbish the South Shaft of the Copper Cliff project, which was shut down in 2008 due to cash constraints after the project was broken down into three phases.

Full production from the Copper Cliff project is estimated to start in 2020 to 2021, with a capacity of up to 6,000 tonnes per day.

The Brazilian giant intends to use battery-powered equipment at Copper Cliff and plans to implement automation to increase productivity.
