Seabridge Gold's Design of KSM Project's Tailing Management Facility Confirmed as Best Available Technology by Leading Engineering Firm

Tuesday, 2nd August 2016

Three Different Expert Reviews Reach the Same Conclusion on Best Design Solution

Toronto (Canada) -- Seabridge Gold announced today the results of its Best Available Tailing Technology (BAT) review for its KSM Project located in British Columbia. The review was completed by Klohn Crippen Berger, a world-leading engineering design firm.  

The BAT study confirms that the existing tailing management facility design, consisting of centerline dams constructed with double cycloned sand and a till core in association with wet tailings deposition, is the best available technology for tailings deposition and the most environmentally responsible design to minimize long term risks associated with the proposed tailing storage facility for the KSM Project. This conclusion confirms the findings from KSM's Independent Geotechnical Review Board that the TMF's design is robust and appropriate for KSM's site specific characteristics (see news release of April 11, 2016).

Seabridge commissioned Klohn Crippen Berger to undertake the BAT review in August 2015 in response to the Independent Expert Engineering Investigation and Review Panel report on the breach of the Mount Polley tailing storage facility. The Review Panel concluded that future projects require not only an improved adoption of best applicable practices (BAP), but also a migration to best available technology (BAT). The Klohn Crippen Berger report also meets the new BC Mining Code requirement that new mines must provide an alternate assessment of BAT in their provincial permit applications.

Seabridge Chairman and CEO Rudi Fronk stated: "We are very pleased that the TMF design we included in the KSM project design that received Provincial and Federal environmental assessment approval has been confirmed in the BAT report as the best possible design for eliminating risks associated with operation and closure. We are further encouraged that Klohn Crippen Berger specifically determined that filtered tailing options are impractical and would result in greater environmental impacts and risks, contrary to the assertions of many environmental groups who have advocated that only filtered tailing disposal technologies should be implemented. I would like to thank Klohn Crippen Berger for their exemplary work in completing this study." 

As a further step in its review process, Seabridge commissioned an independent review of the BAT report by Dr. Dirk van Zyl.  Dr. van Zyl is a world-recognized expert in tailings, mined-earth structures and sustainability with over 40 years of experience. He is currently a faculty member at UBC's Faculty of Applied Science and was a member of the Independent Expert Engineering Investigation and Review Panel investigating the Mount Polley tailing storage facility breach.  In his review of the Klohn Crippen report, Dr. van Zyl states: "I support the overall conclusions of the KSM BAT report. The evaluation shows that using filtered tailings at this project is not a feasible option as it will not result in moving to zero failures. Adding complexity in tailings management, as filtered tailings will do at the KSM site, does not promote the overall goal of moving to zero failures."

Seabridge Gold holds a 100% interest in several North American gold resource projects. The Company's principal assets are the KSM and Iskut properties located near Stewart, British Columbia, Canada and the Courageous Lake gold project located in Canada's Northwest Territories.
