Closing of the second tranche of the Offering and the upsized Private Placement is expected to occur on July 10^th, 2026.

Any additional proceeds will be used for general corporate and working capital purposes.

Closing of the second tranche of the Offering and upsized Private Placement is subject to certain customary conditions including receipt of all necessary approvals, including satisfaction of the listing conditions of the TSX Venture Exchange ("TSXV"). The Offering and the Private Placement may be closed in one or more tranches. All securities issued in connection with the Offering and the Private Placement will be subject to a statutory hold period expiring four months and one day after the issuance thereof.

The Company may pay further cash finders' fees in connection with the upsized Private Placement, as permitted by applicable securities laws and the rules of the TSXV.
