Cementation Canada underground ore and waste handling system contract award for Alamos Gold’s Island
Cementation Canada says it been awarded the ore and waste handling system construction contract at the Alamos Gold Inc Island Gold Mine in Dubreuilville, Ontario. It stated: “Work is starting to take shape, and we’re excited to be returning to Island Gold after supporting underground development and construction projects in 2019 and 2021…we look forward to contributing to another safe and successful chapter at Island Gold.”
Cementation and Alamos teams have worked together over the years on a wide range of underground mining and construction services, grounded in a shared commitment to safety, innovation, and operational excellence. Cementation also says it is honoured to partner with the Missinabie Cree Business Corporation, supporting meaningful and sustainable development on traditional Missanabie lands.
The details of the ore and waste handling system plans are outlined in the Technical Report for the Island Gold Mine expansion which was filed March 20, 2026. The underground ore and waste handling system is designed to accommodate the mine plan’s 3,000 t/d of ore and an additional 2,500 t/d of waste for any future mine development. Waste in excess of the ore and waste handling capacity will be direct deposited underground (co-disposed) in relation to backfill activities).
The system is to be completed in phases, with the loading pocket expected to be completed in Q4 2026, allowing for the hoisting of ore and waste through the
waste side of the system, and the crusher installation expected to be completed in H1 2027, allowing for the ore and waste sides to be independently handled.
The system will have a truck dump with a rock breaker for ore on 840L, a truck dump with a rock breaker for ore on 1050L, and truck dumps with rock breakers for ore and waste on 1265L. Those ore passes will arrive at a primary jaw crusher on 1265L. The crusher will discharge to a fine ore bin which feeds the loading pocket on 1350L. All waste reports to a bin which in turn feeds the 1350L loading pocket. All ore and waste passes will have grizzlies with 400 mm x 400 mm openings.
The loading pocket will be a conventional design with vibratory feeders and conveyor feeding measuring flasks. The conveyor will discharge to a transfer car to alternatively divert material to one of two measuring flasks, which also weigh the payload. Each measuring box discharges into the parked skip in the shaft via dedicated discharge gates and arc gate controls. The skips will be stabilised using the Levelok Skip Holding System.
