About Myriad Uranium Corp.

Myriad Uranium is a uranium exploration company with an earnable 75-per-cent interest in the Copper Mountain uranium project in Wyoming, United States. Copper Mountain hosts several known uranium deposits and historic uranium mines, including the Arrowhead mine, which produced 500,000 pounds of triuranium octoxide. Copper Mountain saw extensive drilling and development by Union Pacific during the late 1970s including the development of a mine plan to fuel a planned fleet of California Edison reactors. Operations ceased in 1980 before mining could commence due to falling uranium prices. Approximately 2,000 boreholes have been drilled at Copper Mountain, and the project area has significant exploration upside. Union Pacific is estimated to have spent $117-million (2024 dollars) exploring and developing Copper Mountain, generating significant historical resource estimates. The company also has a 100-per-cent interest, subject to completing a geophysical survey by Jan. 31, 2026, in the Red Basin uranium project in New Mexico, which has extensive near-surface uranium mineralization and significant upside potential.
