Myriad Acquires Earnable 75% Interest in the Copper Mountain Uranium Project in Wyoming, USA

Vancouver, British Columbia--(Newsfile Corp. - October 20, 2023) - Myriad Uranium Corp. (CSE: M) (OTCQB: MYRUF) (FSE: C3Q) ("Myriad" or the "Company") is pleased to announce that it has signed a property option agreement dated as of October 18, 2023 (the "Option Agreement") with Rush Rare Metals Corp. ("Rush") pursuant to which Myriad has the option (the "Option") to earn up to a 75% interest in and to Rush's Copper Mountain Project (the "Property"), comprised of 110 mineral claims in the State of Wyoming covering approximately 1,911 acres. The Option Agreement replaces the binding letter of intent between the parties, as previously announced (see Myriad's news release dated September 18, 2023).

"This is a transformative deal for us with a superb partner in Rush," stated Myriad's CEO, Thomas Lamb. "Copper Mountain is a historic producer. One of its mines, the Arrowhead, produced 500,000 lbs eU₃O₈ in the 1950s and 1960s. The Property contains a number of other known uranium deposits and there is good potential to discover more. Rocky Mountain Energy, a subsidiary of Union Pacific, drilled approximately 2,000 boreholes at Copper Mountain between 1969 and 1980. They spent upwards of US$78 million advancing Copper Mountain (2023 dollars), planned a mine for one of its deposits, and built a leach pad. Operations came to a halt in 1980 due to falling uranium prices. There is also a great deal of exciting exploration upside at Copper Mountain. Known high-grade areas have not yet been followed up, and new, more modern paragenesis theories could guide us to big discoveries. Finally, historical reports suggest the ore at Copper Mountain is leachable and does not require a mill, and it may even be ISR-amenable. Wyoming is the centre of uranium mining in the USA and many of its operations are ISR."

Under the Option Agreement, Myriad has the option to acquire an initial 50% interest in the Property by: (1) making an initial cash payment of $100,000 to Rush and issuing 576,209 common shares of Myriad (each, a "Share") to Rush on the date of execution (the "Effective Date") of the Agreement; (2) making an additional cash payment of $35,000 to Rush on the date which is 90 days from the Effective Date; (3) issuing an additional $150,000 worth of Shares to Rush on the date which is one year from the Effective Date; (4) issuing an additional $250,000 worth of Shares to Rush on the date which is two years from the Effective Date; and (5) within two years of the Effective Date, making expenditures of no less than $1,500,000 on the Property. On successfully earning a 50% interest in the Property, Myriad will have the option to acquire an additional 25% interest (for a total interest of 75%) in the Property by making additional expenditures of no less than $4,000,000 (for total expenditures of no less than $5,500,000) on the Property within four years of the Effective Date. In addition, upon completion of a Preliminary Economic Assessment or Prefeasibility Study respecting the Property, Myriad shall be obligated to issue an additional $2,500,000 worth of Shares to Rush.

Upon Myriad successfully earning a 50% or 75% interest in and to the Property, as the case may be, the parties will form a joint venture for the purposes of the continued exploration, development and exploitation of the Property and will negotiate, execute and deliver a joint venture agreement which shall include such terms and conditions normally provided for in commercial transactions of such nature that are mutually acceptable to the parties including without limitation: (i) the operator of the joint venture from time to time; (ii) Myriad's potential right to earn an additional 25% interest (for a total interest of 100%) in and to the Property at fair market value; and (iii) a 50% net profit interest held by Rush on the initial $50,000,000 in net profits from the Property, following commencement of commercial production.

Any Shares issued under the Agreement will be subject to a four month hold period under applicable securities laws. The Shares issued as of the Effective Date are subject to a four month hold period expiring February 20, 2024. The value of any Shares issued under the Agreement following the Effective Date will be the value weighted average trading price of the Shares on the Canadian Securities Exchange (or such other Canadian stock exchange on which the Shares are trading at the applicable time) for the 10 trading days preceding the date on which such Shares are issued.
