Recent history shows multiple instances where generally positive corporate news was followed by negative price reactions.
Over the last month, Seabridge Gold has issued several largely constructive updates, yet shares often traded lower afterward. A Q1 2026 filing reported a net loss of $6.6M and a -5.11% move. Shareholders then strongly approved the Valor Gold spin-out, followed by closing that transaction, but reactions were modest to negative (-0.73%, +0.17%). Awards for KSM and a 2025 Sustainability Report also preceded declines. Today’s KSM-related court decision fits into this pattern of sensitive reactions around major project and governance milestones.

Court Requires BC to Consult Further with TSKLH before Reconsidering Determination
Toronto, Ontario--(Newsfile Corp. - June 8, 2026) - Seabridge Gold Inc. (TSX: SEA) (NYSE: SA) ("Seabridge") reports today that the Supreme Court of British Columbia ("the Court") issued its decision on two petitions challenging the determination by the BC Environmental Assessment Office ("EAO") that Seabridge Gold's KSM project located in northwestern British Columbia was substantially started as of July 24, 2024. The Court found that the determination was reasonable but that the EAO had not engaged in sufficient consultation with one of the petitioners, the Tsetsaut Skii km Lax Ha ("TSKLH"). The Court has ruled that the EAO must provide a specific period of 90 days for TSKLH to provide written submissions on whether the project was substantially started, after which the EAO must reconsider the substantial started determination. The Court also dismissed a second petition that was filed by SkeenaWild Conservation Trust against the Substantially Started determination. The decision can be found in its entirety here.
Seabridge Chair and CEO Rudi Fronk noted that work at KSM would continue during the consultation process and EAO reconsideration of the Substantially Started determination. "We are satisfied that the Court has confirmed the reasonableness of the EAO determination. We will continue to execute our work plans for KSM and look forward to meeting with the EAO to receive an update on their additional consultation activities in due course. Meanwhile, the permanent physical improvements we have made at KSM which were considered appropriate for the determination have been significantly enhanced. We remain appreciative of the continued support of the Nisga'a and Tahltan Nations, and the Gitxsan Hereditary Chiefs Office, for KSM."
Since its application for Substantially Started Status in January, 2024, Seabridge has incurred an additional
