About Myriad Uranium Corp.

Myriad Uranium Corp. is a uranium exploration company with an earnable 75% interest in the Copper Mountain Uranium Project in Wyoming, USA. A recent press release discussing the 1982 U.S. Department of Energy assessment of Copper Mountain's uranium endowment can be viewed here. Copper Mountain hosts several known uranium deposits and historic uranium mines, including the Arrowhead Mine which produced 500,000 lbs of U₃O₈. 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 C$117 million (2024 dollars) exploring and developing Copper Mountain, generating significant historical resource estimates which are detailed here. The Company also recently acquired, subject to completing a geophysical survey this year, a 100% interest in the Red Basin Uranium Project in New Mexico, which has extensive near-surface uranium mineralisation and significant upside potential.
