Tudor Abandons Appeal of the BC Chief Gold Commissioner’s Decision
Pertaining to Seabridge Gold’s KSM’s Mitchell Treaty Tunnels (MTT)
Toronto, Canada … Seabridge Gold Inc. (“Seabridge” or the “Company”) (TSX:SEA) (NYSE:SA)
announced today that Tudor Gold Corp. (“Tudor”) has filed a Notice of Abandonment of Appeal with
the Supreme Court of British Columbia, thereby abandoning its appeal of the Chief Gold
Commissioner’s (CGC) decision relat ing to her authority to hear an application challenging KSM’s
Mitchell Treaty Tunnels (MTT). The CGC’s decision, issued on May 28, 2025, declined jurisdiction over
an application brought by Tudor seeking a determination that Seabridge’s KSM MTT Conditional
Mineral Reserve (CMR) in respect of the MTT should not apply to Tudor or, in the alternative, that
the KSM MTT CMR be cancelled. By abandoning the appeal, Tudor has accepted the CGC’s decision
regarding her jurisdiction. Seabridge reported the initiation of the appeal on July 14, 2025.
The CMR requires the current holders of the mineral claims through which the MTT pass not to
obstruct, endanger, or interfere with the construction, operation, or maintenance of the MTT. The
legal effect of the CMR has been confirmed by representatives of the BC Ministry of Mines on
multiple occasions going back over 11 years. The MTT are a critical infrastructure component of the
KSM Project, consisting of two parallel tunnels connecting the east and west sides of the mine site.
Approximately 12.5 kilometers of the MTT will pass through mineral claims owned by Tudor.
Seabridge Chair and CEO Rudi Fronk stated: “We applaud Tudor’s decision to abandon its appeal,
which lacked any merit from the outset. This action reinforces our position that the authorizations
issued in favour of the MTT do not give Seabridge any interest in Tudor’s mineral rights.”
