Cementation Canada Inc has been awarded the design and construction of the new internal underground shaft for the Onaping Depth Project at  Craig Mine, part of Glencore’s Sudbury Integrated Nickel Operations (Sudbury INO) in northeastern Ontario.

The deposit is approximately 2,500 m 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 m 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 reaming a three-metre diameter raise bore as a pilot raise for a portion of the final shaft excavation and construction.

“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,” said Roy Slack, President of Cementation Canada. “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.”
