Cementation Canada has been awarded the ore and waste handling system construction contract for the Island Gold Mine, operated by Alamos Gold Inc., located in Dubreuilville, Ontario, Canada.
The company confirmed that work is already progressing and marks a return to the site, having previously supported underground development and construction projects in 2019 and 2021. Cementation highlighted its ongoing collaboration with Alamos Gold, built on a shared focus on safety, innovation and operational performance.
Cementation also noted its partnership with the Missinabie Cree Business Corporation, supporting sustainable development initiatives on traditional Missanabie Cree lands.
According to the Island Gold Mine expansion Technical Report filed in March 2026, the underground ore and waste handling system is designed to support production of 3,000 tonnes per day of ore and an additional 2,500 tonnes per day of waste. Any excess waste will be managed through underground co-disposal linked to backfill operations.
The system will be developed in phases. The loading pocket is scheduled for completion in the fourth quarter of 2026, enabling hoisting through the waste circuit, while installation of the crusher is expected in the first half of 2027, allowing ore and waste streams to be handled independently.
Infrastructure will include multiple truck dump stations with rock breakers at different levels—840L, 1050L and 1265L. Ore passes will feed into a primary jaw crusher at 1265L, with crushed material directed to a fine ore bin before moving to the loading pocket at 1350L. Waste material will be routed through a separate bin system feeding the same loading pocket. All ore and waste passes will be fitted with grizzlies featuring 400 mm by 400 mm openings.
The loading pocket will use a conventional configuration, incorporating vibratory feeders and conveyors linked to measuring flasks. A transfer car system will direct material between two flasks, which weigh the payload before discharging into shaft skips. The skips will be stabilised using a Levelok Skip Holding System, ensuring controlled and efficient hoisting operations.
The project forms part of the broader Island Gold Mine expansion, aimed at increasing production capacity and improving operational efficiency.
