Tunnel Status For Seabridge’s KSM Project

Challenged by Tudor Gold

T

oronto, Canada … 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.

Sea

bridge’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.”

I

f 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.
