Project Details
Location: Gold Mine, Northern Ontario
Time Frame: August 2021 - July 2022
Project Value: $8,000,000
Contract Type: Unit Rate
Services Rendered: Mine Development
Project Summary
Morgan was engaged to construct a 3.7km 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.
Project Scope
Phase 1:
1.8 km of road was built for light vehicles, using Zone 5 rockfill material
A 1.8 km long ditch was excavated and lined with Zone 5A rockfill material for protection
A 29,000 m3 holding pond was dug out
A 1800mm diameter concrete reinforced manhole was installed
A 600mm HDPE intake pipe was installed
Water was properly managed during excavation activities
Phase 1 work activities were completed ahead of schedule
Phase 2:
Built a 1.9 km road for light vehicles using Zone 5 rockfill material
Dug and armored 1.9 km of ditches using Zone 5A rockfill material
Excavated a 36,000 m3 holding pond
Installed a 1800mm diameter concrete reinforced manhole
Installed a 600mm HDPE intake pipe
Managed water during excavation activities

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.
