Construction underway on infrastructure for Vale's $750M Copper Cliff mine expansion

Construction is underway in Copper Cliff on a set of massive ventilation fans to supply fresh and warm air to miners below.

It's part of Vale's $750 millionrefurbishing of the existing Copper Cliff north and south mines.

Danica Pagnutti, the mining company's senior advisor on corporate and Indigenous affairs, says workers will be tackling new ore bodies beneath Copper Cliff beginning in 2021.

"This is really about the future of our operations here in Sudbury. It represents a major expansion and new sources of ore for our operations, so this is a very important project for us," she says.

"We're going to need 200 miners and 200 tradespeople and a whole host of supporting roles. It's a great time at Vale and we are hiring."

The Copper Cliff south mine have been sitting idle since 2009 and much of the mine's infrastructure, such as the shaft, needs to be refurbished.

Pagnutti says the ventilation system is being equipped with sound dampening equipment so it won't bother those living near the mine.

She says Vale also plans to use the new Copper Cliff mine to experiment with autonomous electric scoop vehicles.

The mine could also be expanded in the future to mine ore bodies close to Kelly Lake that are currently being studied.

Crosstown rival Glencore is also looking to re-open an old mine, with $1 billion earmarkedto be spent at the old Craig mine.

That project, which Glencore calls "Onaping Depth", is expected to be at full production by 2025.
