NOTICE AND ACCESS NOTIFICATION TO SHAREHOLDERS
ANNUAL GENERAL MEETING OF SHAREHOLDERS
TO BE HELD ON THURSDAY, DECEMBER 4, 2025

You are receiving this notification because Giant Mining Corp. (the "Company") has opted to use the "notice and access" model for the delivery of its management information circular (the "Circular") to the holders (the "Shareholders") of common shares in the capital of the Company in respect of its annual general meeting of Shareholders to be held virtually on Thursday, December 4, 2025 (the "Meeting").

Under "notice and access" instead of receiving paper copies of the Circular, Shareholders are receiving this notice with information on how to access the Circular electronically. Shareholders will also be receiving a proxy or voting instruction form, as applicable, together with this notification to use to vote at the Meeting.
