 Toronto, Ontario--(Newsfile Corp. - July 14, 2025) - Seabridge Gold  Inc. (TSX: SEA) (NYSE: SA) ("Seabridge" or the "Company") announced  today that Tudor Gold Corp. ("Tudor") has filed a Notice of Appeal in  the British Columbia Supreme Court against the Chief Gold Commissioner  of British Columbia (the "CGC") and Seabridge which appeals a decision  of the CGC rejecting an application brought by Tudor that seeks, in  effect, to rescind the legal mechanism which prioritizes Seabridge's  rights to use land passing through Tudor's claims for the KSM Project's  Mitchell Treaty Tunnels ("MTT").  Tudor previously had applied for a  decision from the CGC that KSM's conditional mineral reserve (the "CMR")  in respect of the MTT should not apply to Tudor or, in the alternative,  that the CMR be cancelled. The CGC rejected Tudor's application. The  CGC's decision can be found  here.
 
 Seabridge's  CMR requires that "a free miner must not obstruct, endanger or  interfere with, or allow any other person to obstruct, endanger or  interfere with, the construction, operation or maintenance of" the MTT.   Tudor is a free miner. Tudor is, among other things, arguing that  Seabridge's Licence of Occupation for the MTT gives it a competing claim  to minerals in Tudor's claims and therefore must be adjudicated by the  CGC. Seabridge does not claim any rights to the minerals in Tudor's  Treaty Creek Project, whether under its Licence of Occupation or  otherwise.  Accordingly, Seabridge considers the CGC's decision to  reject Tudor's application to be correct. "After Tudor's initial  submission to the CGC on January 28, 2025, followed by four additional  submissions through April 17, 2025 raising every argument Tudor could  devise, the CGC concluded that she did not have the jurisdiction to make  the decisions requested by Tudor.  Tudor now appears to be trying to  obtain a court decision that the CMR does not apply to it" said  Seabridge's Chair and CEO, Rudi Fronk.  "We are confident that the judge  will dismiss Tudor's appeal."
 
 If Tudor is successful with its  appeal, the outcome would be that the court orders the CGC to take  jurisdiction and make a decision in response to Tudor's application.  It  would then be up to the CGC to decide whether to accept Tudor's  arguments that the CMR does not apply to Tudor.  In the interim, the CMR  remains in place.  It is also worth noting that: (i) in 2014, early  2024 and again in April, 2025, the Ministry of Mines stated that the CMR  applies to Tudor and that: (ii) in the decision under appeal by Tudor,  the CGC stated that the CMR applies to Tudor, and  that: (iii) in the  decision under appeal by Tudor, the CGC decided not to exercise her  discretion to cancel the CMR.
