Location: Gold Mine North Cochrane District, Ontario
Time Frame: April 2023 - October 2024
Project Value: $35,000,000
Contract Type: Unit Rate
Services Rendered: Mine Development
Project Summary
Morgan was hired to construct a multi-year tailings dam raise at a major open pit gold mine in Northern Ontario. This project involves constructing a cross section of dam that includes various filter zones, large fills, and the supply and install of a geomembrane liner, to raise the tailings dam by 9 m over a 4 km section. The purpose of the project is to increase storage capacity of the main tailings facility, ensuring mining can continue uninterrupted into the future.
Project Scope
Tailings Dam Raise (296.0m – 301.0m)
Completion of 4 km of a 5 m dam raise utilizing various rockfill and chimney drain materials, and installation of BGM liner.
Construction of tailings pond spillway.
Load, haul, and place upstream and downstream Coarse Rockfill material (267,384 m3).
Load, haul, and place upstream and downstream Fine Rockfill material (159,238 m3).
Load, haul, and place chimney drain materials utilizing a drag box:
Till material (28,790 m3)
Fine Filter material (40,415 m3)
Coarse Filter material (40,463 m3)
Load, haul, and place slope cover and anchor berm materials (26,716 m3).
Installation of Bituminous Geomembrane liner material (59,967 m2).
Management of quality control and testing requirements on all material placement activities.
Tailings Dam Raise (301.0m – 305.0m)
To be completed in 2024.
Projects
Our innovative mining portfolio
Our proven track record of success in the mining sector is what separates Morgan from the rest of the market. Take a look at some of our recent milestone projects.
Overburden Ditching and Ponds
Morgan was engaged to construct a 3.7 km long rock-lined filtration ditch intended to capture any dirty water and provide containment, mitigating environmental risk associated with surface runoff. In addition to the filtration ditches, the filtration network included two large ponds which assist with storage requirements and allow for dissipation.

TA9 Engineered Pond Bottom Cleanup
As our client progresses their mining operation, they intend to utilize a portion of the pit to store tailings which requires the installation of an engineered, competent base. A key component of this work is removing slop and unsuitable material from the existing ground that is left over from the previous mining operation.

Mackenzie Redcap Expansion - Soil Salvage and Culverts
Morgan salvaged 900,000 m3 of surface soil in advance of the construction of the Mackenzie Recap Expansion haul road. The project’s right of way crossed through multiple environmentally sensitive areas that required extensive dewatering efforts. Morgan developed location-specific dewatering plans to successfully move and treat the groundwater, reducing the risk of siltation prior to salvaging the surface soils.

North Mine Advance – Reclamation Material Salvage
As part of Mildred Lake operations reclamation scope Morgan has been trusted to remove and salvage all surface soils and subsoils in advance of mining operations for the 2021 and 2022 reclamation seasons. Reclamation salvage is critical to our client’s operations as the surface soils must be stockpiled and stored to be reused at the end of the mine life. Morgan has successfully and safely removed and salvaged over 7.5 million m3 of soil during these two seasons resulting in a long-standing partnership.

Mildred Lake Extension - West Access Road
To facilitate the development of a new oilsands mine our client trusted Morgan with the construction of 10 km of access road. Included in this project was the construction of five major water crossings, two of which were large-diameter steel culverts and three concrete bridge structures on steel-driven piles. In addition to the 10 km of high-grade road, Morgan was also tasked with the construction of a permanent laydown area that will serve as the construction management team’s office location and material storage throughout the development of the new mine.
