Glencore awards Onaping Depth contract to Cementation Canada – by Staff (Sudbury Star – September 19, 2018)

Canada Inc. said Tuesday it has been awarded the design and construction of the new internal underground shaft for the Onaping Depth Project at Craig Mine. The mine is part of Glencore’s Sudbury Integrated Nickel Operations (Sudbury INO).

“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,” Roy Slack, president of Cementation Canada, said in a 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 Canada did not say how much the contract was worth. Glencore, however, has freed up $700 million for Onaping Depth. Production at Onaping Depth expected to begin in 2023 — and go fully online by 2025.

The deposit is about 2,500 metres below surface and is critical to the long-term sustainability of Sudbury INO’s operations in the Sudbury basin. Cementation will design and construct the 7.2-metre diameter production shaft.

The shaft will be sunk from the 4025 Level of Craig Mine and is approximately 1.5 km horizontally from the existing Craig shaft. Cementation will engineer and construct the hoistrooms and underground headframe, and is currently widening a three-metre diameter raise bore as a pilot raise for a portion of the final shaft excavation and construction.
