Copper Cliff and Onaping Depth projects underway
Vale and Glencore’s Sudbury Integrated Nickel Operations have received board approval for major mine development projects in the Sudbury Basin.
Following several delays attributable to low commodity prices, Vale is proceeding with a C$760 million phase one development of its Copper Cliff Deep project, while Glencore is moving ahead with a C$900 million development of Onaping Depth.
Both projects are being undertaken to replace declining production from established mines.
“I don’t think it’s a surprise to anyone that most of our mines are facing declining production profiles,” said Vale’s Dave Stefanuto, vice-president, capital projects for the North Atlantic. “We need to find replacement volumes of ore, so we’re starting to focus more on what we can do to start supplementing these declining orebodies. In the last few years, we spent a lot of time focusing on our surface plants, including the $1 billion Clean AER project. We’ve invested enough in our surface facilities. Now we have to feed them because they’re no good if they’re running empty.”
