TORONTO, ON – March 11, 2025 – Critical One Energy Inc. (formerly Madison Metals Inc.) (“Critical One” or the “Company”) (CSE: CRTL) (OTCQB: MMTLF) (FSE: 4EF0) is announcing the expiration of its previously announced deal with Star Minerals Limited (“Star Minerals”) (ASX: SMS) to earn into Exclusive Prospecting Licence 8531 (the “Cobra Uranium Project”) at Madison North near the world-renowned Rossing Uranium Mine in the Erongo Uranium Province, Namibia.

Under the terms of the agreement announced on September 19, 2024, Star Minerals had the opportunity to earn up to a 51% interest in the Cobra Uranium Project through staged cash payments, the issuance of common shares to the Company, and expenditures on the Cobra Uranium Project. In December 2024, Star Minerals requested an extension of the closing to early March 2025. Star Minerals did not meet its commitment and therefore did not earn any interest in the Cobra Uranium Project.

As a result, Critical One continues to hold an 85% interest in the Cobra Uranium Project and received a US$40,000 non-refundable deposit, a US$75,000 payment and 5.3 million common shares of Star Minerals.
