Myriad Uranium Appoints Eric Miller as Strategic Advisor on US Critical Minerals

Vancouver, April 28, 2026 - Myriad Uranium Corp. (CSE: M) (OTCQB: MYRUF) (FSE: C3Q) ("Myriad" or the "Company") is pleased to announce the appointment of Eric Miller as Strategic Advisor, effective immediately. Mr. Miller will focus on advancing Myriad's flagship Copper Mountain uranium project in Wyoming by leveraging the growing suite of federal and state policy tools designed to accelerate U.S. domestic uranium supply.

Thomas Lamb, CEO, commented: "Eric Miller brings an extensive record at the intersection of U.S. government policy and critical minerals development. He has worked directly on high-profile critical minerals initiatives with the U.S. federal government and on behalf of resource companies navigating the U.S. regulatory support, funding program, and interagency coordination landscape. His network spans the agencies and congressional offices responsible for implementing DPA Title III authorities, DOE programs, and permitting reform, positioning him to build the relationships essential to advancing Copper Mountain."

U.S. Critical Minerals Policy and the Defense Production Act

The United States is confronting a structural uranium supply crisis. Despite operating the world's largest fleet of nuclear reactors, the U.S. currently imports a high ratio of its uranium requirements from Russia, Kazakhstan, and Uzbekistan - a concentration of supply identified at the highest levels of government as a national security vulnerability.

Uranium has been formally designated a "Critical Mineral" by the U.S. federal government, and the current Administration has invoked the Defense Production Act (DPA) - specifically Title III, which authorizes direct financial assistance including grants, loans, and purchase commitments to domestic producers of materials essential to national defense - to stimulate domestic uranium production. This designation and the associated DPA authorities also open the door to expedited permitting, priority federal procurement consideration, and eligibility for Department of Energy funding programs.

Copper Mountain, located in Wyoming - the largest uranium-producing state in the U.S. - is well-positioned to benefit directly from these policy mechanisms as they are operationalized.

About Myriad Uranium Corp.

Myriad Uranium Corp. holds a 75% interest in the Copper Mountain Uranium Project in Wyoming, USA, with a definitive agreement in place to acquire the remaining 25% interest from Rush Rare Metals Corp. Copper Mountain hosts multiple historic uranium deposits and past-producing mines, including the Arrowhead Mine (approximately 500,000 lbs U₃O₈ produced). The district saw extensive exploration and development by Union Pacific in the late 1970s, including approximately 2,000 boreholes and advanced mine planning prior to uranium market downturn conditions in 1980. Union Pacific is estimated to have invested approximately C$117 million (2024 dollars) in exploration and development at Copper Mountain, generating significant historical resource estimates. The Company also holds a 100% interest in the Red Basin Uranium Project in New Mexico, USA, but has entered into an agreement to sell the project to Subatomic, a new venture backed by leading U.S. technologists. Myriad will retain a 10% free carried interest and enter into a strategic alliance with Subatomic.
