Dumas had an integrated role in building one of the most significant gold mines in Timmins. From the concept and design stage of the project in 2007 to the development phases, we excavated a concrete lined exploration shaft to a depth of 710 metres. The scope of work also included engineering and construction of the shaft collar, head frame and hoist infrastructure.

At the 650 metre level, we excavated the forth shaft station and lateral development drift to a 30,000 ton bulk sample zone. Dumas achieved a remarkable average sinking rate of 10.8 feet per day.

Additionally, Dumas crews undertook one of our crown raising achievements, a 397 metre raise that was delivered two weeks ahead of schedule without injury or incident.
