Cementation Canada has been awarded the contract to build the underground shaft for Glencore’s Onaping Depth project.

The nickel-copper-PGE project, an initiative of Glencore’s Sudbury Integrated Nickel Operations (INO), is located at Craig Mine, about 2,500 metres below surface and a 45-minute drive outside of Sudbury.

The deposit was first discovered in 1994, and the US$700-million development project received approval this past January.

“Onaping Depth has been an iconic project for us and we have worked very closely with Sudbury INO over the years to evaluate and provide the shaft designs and methodology that combine safety with value,” Cementation president Roy Slack said in a Sept. 18 news release.

“We are thrilled that the project is going ahead and are very excited to be Sudbury INO’s main contractor and design engineer for this shaft project.”

Cementation’s work will include the design and construction of a 7.2-metre production shaft, which will be sunk from the 4025 level of Craig Mine, as well as the engineering and construction of the hoistrooms and underground headframe.

The company said it’s currently constructing a three-metre raise bore as a pilot raise for a portion of the final shaft excavation and construction.

Headquartered in North Bay, Cementation builds underground mine infrastructure and surface material-handling and processing facilities around the globe.

It has offices in Sudbury, Rouyn-Noranda, Que., Vancouver, B.C., and Salt Lake City, Utah.
