James Pit Re-Design

The re-design of the James South Pit was required due to two concerns:

  1. 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

  2. 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
