NOTICE REGARDING USE OF NOTICE-AND-ACCESS PROCEDURES FOR ANNUAL GENERAL MEETING MATERIALS

You are receiving this notification as Seabridge Gold Inc. (the “Company”) has decided to use the notice-and-access procedures for the delivery of meeting materials to its shareholders in respect of its annual general meeting of shareholders to be held on June 28, 2023 (the “Meeting”).

Under notice-and-access, instead of receiving paper copies of the Company’s management proxy circular for the Meeting (the “Circular”), shareholders are receiving this notice with information on how they may access the Circular electronically. However, together with this notice, shareholders as of May 4^th, 2023, the record date of the Meeting, continue to receive a Notice of Meeting and a proxy or voting instruction form, as applicable, enabling them to vote at the Meeting. The use of this alternative means of delivery is more environmentally friendly as it will help reduce paper use and it will also reduce the Company’s printing and mailing costs in respect of the Meeting.

MEETING DATE AND LOCATION

SHAREHOLDERS WILL BE ASKED TO CONSIDER AND VOTE ON THE FOLLOWING MATTERS:

• FIXING THE NUMBER OF DIRECTORS: To fix the number of directors of the Company at eleven (11). See the section entitled “Business of the Meeting - Election of Directors” in the Circular.

• AUDITORS’ REMUNERATION: To authorize the directors to fix the auditors remuneration. See the section entitled “Business of the Meeting – Appointment and Remuneration of Auditor” in the Circular.

• AMEND BY-LAWS: To approve, by ordinary resolution, the amendment of the By-Laws of the Company to eliminate the casting vote of the Chairman at directors meetings. See the section entitled “Business of the Meeting – Amendment of By-Laws” in the Circular.

• OTHER MATTERS: Shareholders may be asked to consider other items of business that may be properly brought before the Meeting.
