TO BE HELD ON FEBRUARY 27, 2024

NOTICE IS HEREBY GIVEN that the Annual General Meeting (the “ Meeting ”) of shareholders of Koryx Copper Inc. (the “ Company ”) will be held via virtual meeting on February 27, 2024, at 11:00 a.m. (Pacific Time), for the following purposes:

1. to receive and consider the audited consolidated financial statements of the Company for its fiscal year ended August 31, 2023, together with the auditor’s report thereon;

2. to set the number of directors at six (6);

3. to elect directors of the Company for the ensuing year;

4. to appoint Crowe MacKay LLP, Chartered Professional Accountants, as auditor of the Company for the ensuing year and to authorize the directors to fix the auditor’s remuneration;

5. to re-approve the Company’s rolling Omnibus Plan as more particularly described in the management information circular dated January 12, 2024 (the “ Information Circular ”); and

6. to transact any other business which may properly come before the Meeting.

Virtual Meeting

This year the Company will be holding its Meeting in a virtual only format. Shareholders will have an equal opportunity to participate at the Meeting online regardless of geographic location. Registered shareholders and proxyholders will be able to attend the Meeting and vote virtually. Non-Registered shareholders who have not duly appointed themselves as proxyholder will be able to attend the Meeting as a guest but will not be able to vote at the Meeting. This voting restriction results from the transfer agent not having a record of non-registered shareholders, such that it would be unable to confirm shareholdings or entitlement to vote unless they appoint themselves as proxyholder. Please see “ Appointment and Revocation of Proxy ” below in the accompanying Information Circular.

Attending the Meeting Virtually

Shareholders will not be able to attend the Meeting in person . Instead, Registered Shareholders and duly appointed proxyholders can virtually attend, participate, vote or submit questions at the virtual Meeting online and non-registered shareholders will be able to attend the virtual Meeting online by registering before February 25, 2024 at the following link:
