B.C. Government Files Responses to Petitions Challenging KSM's Substantially Started Designation

Toronto, Ontario--(Newsfile Corp. - April 23, 2025) - Seabridge Gold Inc. (TSX:SEA) (NYSE:SA) ("Seabridge" or the "Company") reported today that the BC Government has filed its responses in BC Supreme Court to petitions challenging the Environmental Assessment Office's ("EAO") decision granting Seabridge Gold's KSM project a Substantially Started ("SS") Designation. On July 29, 2024, the EAO determined that Seabridge's KSM project had been substantially started ensuring that the project's Environmental Assessment Certificate is no longer subject to expiry.

The responses filed by the BC Government succinctly lay out the meetings held, and other communications made, as well as the responses to requests received, by the BC government to fulfill its duty to consult and its duty of procedural fairness to the petitioners on the SS determination. The responses also explain why granting the SS Designation was not unreasonable. The petitions, the BC Government's responses and our related news releases can be found here. The parties have scheduled the period from September 22 to September 29, 2025 for the court hearing.

Seabridge CEO Rudi Fronk stated "we are pleased by the extent of the EAO's consultation, and we are confident in the strength of their arguments that the EAO's decision to grant the SS Designation was procedurally fair and not unreasonable. Seabridge will also file its own response to the petitioners in the next few weeks. While this legal process unfolds, the SS Designation remains in effect."
