Totten Mine is located in Worthington, Ontario, 15km west of Sudbury.

Cementation commenced the Totten project in May of 2007 with the initial temporary dewatering set up. The scope includes full dewatering and shaft rehabilitation for the existing No.2 shaft down to an elevation of 1260m. The existing headframe and surface plant was demolished in 2007 and Cementation carried out the permanent engineering and construction management for the new headframe and hoist house.

Future scope includes the initial access development and the waste handling system replacement or rehabilitation. Concurrent to this work all mobile equipment for the two year lateral development phase will be lowered into the mine and Cementation will be responsible for these shaft activities including the early waste removal.

Concurrent with the shaft dewatering and rehabilitation project, Cementation was awarded and started the raise boring of the ventilation circuit for the Totten mine in 2008. This four raise project includes one raise at a diameter of 5.52m, one raise at a diameter of 5.0m, one raise at a diameter of 3.1m, and the longest raise of 840m at a diameter of 2.4m for a total of 2200m.
