Pursuant to a warrant indenture dated May 1, 2023, a first supplemental warrant indenture dated April 30, 2025 and a second supplemental indenture dated June 6, 2025 (collectively, the "Warrant Indenture") between the Company and Computershare Trust Company of Canada (the "Warrant Agent"), the Company may, at its sole discretion, accelerate the expiry of the Warrants if the closing price of the common shares of the Company (each, a "Common Share") on the TSX Venture Exchange (the "TSXV") exceeds C$0.3125 per Common Share for a period of 10 consecutive trading days (the "Acceleration Trigger"). The Company hereby provides notice (the "Acceleration Notice") that the Acceleration Trigger was reached after market close on May 25, 2026, and that the Company is exercising its right to accelerate the expiry of the Warrants to 4:00 p.m. (Vancouver Time) on July 2, 2026 (the "Accelerated Expiry Date"), which is 30 days following the date that the Acceleration Notice was delivered to holders of the Warrants via news release and written notice.

Warrant holders who wish to exercise their Warrants should review the exercise requirements contained in the Acceleration Notice, the Warrant Indenture and, if applicable, the certificate evidencing their Warrants, and contact their legal and investment advisors before submitting the exercise form and any other applicable documentation to the Warrant Agent. Pursuant to the Warrant Indenture, each Warrant entitles the holder to purchase 0.1 Common Share at an exercise price of $0.025, such that ten (10) Warrants will collectively be exercisable to acquire one Common Share at an aggregate exercise price of $0.25 per Common Share.
