Seabridge Gold’s KSM Tunnel Authorizations Face
Third Legal Challenge from Tudor Gold
It Seeks to Void Licence of Occupation
Toronto, Canada … Seabridge Gold Inc. (the “Company”) announced today that Tudor Gold
Corp. (“Tudor”) has filed a Petition in the British Columbia Supreme Court against the British
Columbia Ministry of Water, Land and Resource Stewardship (“WLRS”) and the Company and
the Company’s wholly-owned subsidiary that owns 100% of the KSM Project , KSM Mining ULC
(together with the Company, “Seabridge” ), seeking judicial review of the September, 2024,
determination by WLRS to grant a Licen ce of Occupation (“ 2024 LoO”) across mineral claims
that are part of Tudor’s Treaty Creek Property (the “Treaty Project Claims”) for the construction
and operation of the KSM Project’s Mitchell Treaty Tunnels (“MTT”).
The 2024 LoO provides Seabridge with the right to occupy a narrow corridor in which it
proposes to construct and operate the MTT. The 2024 LoO was a replacement of a prior Licence
of Occupation that had been issued to Seabridge in 2014 over the same land. The MTT are two
23 km long parallel tunnels planned to connect the east and west sides of the KSM Project Mine
Site. Approximately 12.5 km of the MTT route pass through the Treaty Project Claims.
In its Petition, Tudor is seeking declaration s that: (1) a Licence of Occupation cannot interfere
with the rights of a mineral claims holder; (2) all provisions of the 2024 LoO that grant Seabridge
rights across the Treaty Project Claims are severed from the 2024 LoO; and, (3) an order
quashing WLRS’s decision to grant the 2024 LoO. The Petition includes an allegation that
WLRS’s decision to grant the 2024 LoO was procedurally unfair or unreasonable . The Petition
also asserts that construction of the MTT requires Seabridge to have a right to the Treaty Project
Claims since, according to Tudor : “If constructed according to its current plan, the MTT will
destroy the economic viability of the Treaty Creek Project and remove all reasonable uses of
Tudor’s property.”
As a mineral claims holder, Tudor owns the rights to the minerals within the area of its mineral
claims. However, the land that the Treaty Project Claims covers is land owned by the Province
of British Columbia. The terms of the 2024 LoO are designed to protect Tudor’s rights to the
minerals within its claims; requiring Seabridge to store the small amount of material excavated
during MTT construction within the Treaty Project Claims under Tudor’s ownership .
Construction of the MTT is similar to construction of roads, pipelines, railways, or other
infrastructure across public land. In its Petition, Tudor is essentially asserting that the Province
can’t authorize the construction of infrastructure through land owned by the Province if there
is a mineral claim covering it. If true, that would render large portions of British Columbia
unavailable for construction of infrastructure without the consent of mineral claims holders.
The statutory regime is not set up that way.

“In granting the 2024 LoO, WLRS has exercised its discretion to support the KSM Project, which
has its environmental assessment approvals, a pre -feasibility study d emonstrating economic
viability, substantial investments in early construction and many permits for construction of
infrastructure, including portions of the MTT. KSM has therefore been determined to be in the
interests of British Columbia. Considering that the Treaty Creek Project not only does not have
environmental assessment approvals or a preliminary economic assessment, but has not even
articulated a comprehensive project development plan , I am confident that WLRS has acted
appropriately in authorizing Seabridge to use Provincial land for the MTT .” said Seabridge’s
Chair and CEO, Rudi Fronk. He added: “We have attempted to find terms to avoid a conflict
like this with Tudor, but the ir demands have been unreasonable. Tudor now has three
concurrent, separate legal actions all directed at voiding authorizations for the MTT. In our view,
if Tudor thinks it must bring three separate legal actions, it probably lacks confidence in the
success of any one of them.”
For reference, here are our news releases of July 14, 2025 and October 3, 2025 responding to
Tudor’s previous MTT challenges.
The 2024 LoO is currently unaffected by the filing of the Petition and will remain in place if the
Province and the Company successfully defend the 2024 LoO.
