Independent Geotechnical Review Board

Independent Geotechnical Review Board

Add Location text Here

In January 2015, more than a year before it became a legally mandated requirement, Seabridge established an Independent Geotechnical Review Board (IGRB) for the KSM Project to independently review and provide expert oversight and advice regarding the design, construction, operational management, and ultimate closure of the Tailings Management Facility (TMF) and Water Storage Dam (WSD). The IGRB members combined have over 300 years of experience investigating designing, constructing, and closing mine waste management facilities. 

The purpose of the Board is to:

  • Provide independent opinion as to whether the TMF and WSD including all pertinent control structures or systems, meet accepted design and operational guidelines based on internationally accepted practices;
  • Provide advice and guidance on technical issues associated with the design, construction, operation and maintenance and closure of the TMF and WSD, including all pertinent control structures and systems. This includes commenting on the site characterization programs that will be undertaken to advance the project through Feasibility Studies and into construction; and
  • If the Board considers it warranted, make recommendations regarding improvements to the structures or systems that will enhance the safety and/or longevity of the structures and reduce risks posed by the structures during construction, operations and closure.

This undertaking ensures that our current and future designs are based on best practices to mitigate the long-term risks associated with tailings facilities and water dams, and to protect our employees, local communities, and the local environment.

In April 2016, the IGRB concluded, “The layout and type of structures, the tailings management approach, runoff and seepage control measures, and the closure plans are appropriate for the site conditions and intended purposes.”
