The extended expiry date of an aggregate of 1,414,286 Warrants, issued as part of a non-brokered private placement of units initially announced on February 27, 2024, shall be August 5, 2026 instead of February 27, 2029, as stated. The management of the Corporation sincerely apologize for any confusion this situation might have caused.

The Corporation will issue a follow up press release solely in the case where the Exchange rejects the application for the Amendment.
