James Pit Re-DesignThe re-design of the James South Pit was required due to two concerns:
Structural Integrity of the Pit Wall:
The Pit perimeter was approximately 20 m from a section of the unnamed tributary
The organic layer was much deeper than anticipated and the material lacked the required competency for the current pit design, therefore, the structural integrity of the pit wall had become a concern
Access to additional ore:
To access ore in the eastern section of the pit the pit perimeter had to be pushed out to the east extending past the unnamed tributary
Therefore the pit was re-designed to allow for a more gradual slope which allowed a larger pit floor and access to the identified ore body, i.e.
/ versus _/
This required the removal (de-watering) of approximately 500 m of the upstream section of the unnamed tributary
A diversion pipe was installed to bypass the de-watered section and to deliver flows into downstream section
