The Alamos Island Gold Shaft Project is located west of Dubreuilville, 83 km northeast of Wawa in Northern Ontario. The project consists of an expansion to the mining operations to increase production from 1,200 tonnes per day to 2,000 tonnes per day. The scope of work includes project site surface earthworks for the new mine shaft, infrastructure and construction of the access road, box culvert WC-4B, and underground utilities.
The site had to be cleared and grubbed, stripped, and excavated mechanically or by blasting to facilitate construction. The blast rock was then crushed and processed to produce the engineered materials required for the site backfill, access road, and haul road.
There was also 2.5 km of HDPE piping installed at the project site, including trenching and backfill. Stormwater drainage systems, sediment control, and erosion protection was installed, including drainage culverts and a box culvert for the access road. Fencing was also included in the scope and was installed around the perimeter of the project site.
