Seabridge Granted Two Year Extension on KSM Environmental

Assessment Certificate Due to COVID-19 Related Impacts

Toronto, Canada... Seabridge Gold (TSX:SEA) (NYSE:SA) announced today that as a result of the

impact of COVID -19 measures adopted for the protection of the people and communities of

northwestern B.C. on the schedule for completing site capture and follow -on work at its 100%

owned KSM Project, the British Columbia Minister of Environment and Climate Change Strategy

(the “B.C. Environment Minister”) has granted a two year extension to KSM’s Environmental

Assessment Certificate (“EAC”) through July 29, 2026.

Rudi Fronk, Chairman and CEO of Seabridge stated “ This decision will allow the continued de -

risking and the responsible advancement of KSM. Seabridge would like to thank the leadership of

the Nisga’a and Tahltan Nation s and the Gitxsan Hereditary Chief’s Office for their positive

contributions to our EAC extension request. Thanks, are also extended to the Honourable George

Heyman, BC Minster of the Environment and Climate Change Strategy and the BC Environmental

Assessment Office, for their leadership on this file.”

Under the B.C. Environmental Assessment Act a project’s EAC is subject to expiry if the project has

not been “substantially started” by the deadline specified in the EAC. When determining whether

a project has been substantially started, the B.C. Environment Minister assesses each project

separately on whether sufficient physical work and capital spend on long term project

infrastructure has been completed prior to the EAC deadline. For Seabridge’s KSM Project, the

substantial start deadline was July 29, 2024. H owever, with the two -year extension, the EAC

deadline is now July 29, 2026.

“We are planning on staying well ahead of the new deadline by intensifying ou r field work

beginning next year, ” said Fronk. “This work cuts time from the construction schedule once a

construction decision has been made. As reported in our Q2 and Q3 reports to shareholders,

Seabridge has already commenced road and camp construction at KSM.”

Seabridge holds a 100% interest in several North American gold projects. Seabridge's assets

include the KSM and Iskut projects located near Stewart, British Columbia, Canada, the

Courageous Lake project located in Canada's Northwest Territories, the Snowstorm project in the

Getchell Gold Belt of Northern Nevada and the 3 Aces project set in the Yukon Territory. For a full
