Myriad Uranium Corp. is pleased to announce a significant expansion of its land position at the Copper Mountain Uranium Project in Wyoming, increasing total holdings from approximately 9,439 acres to approximately 18,351 acres. This acreage now covers all key areas and targets across the Copper Mountain district.
The expanded staking program was guided by results from the Company’s recent high-resolution radiometric and magnetic survey. Notably, the vast majority of radiometric anomaly points identified by the survey occur in previously untested ground east of the north–south structural corridor indicated. In contrast, all known historic uranium resources and nearly all previously identified targets at Copper Mountain are located west of this corridor. The southern areas have been added because of other highly positive characteristics.
To determine which areas to acquire, the Company integrated the new geophysical data with its existing geological dataset, including insights derived from the comprehensive studies of Copper Mountain completed by Bendix Field Engineering Corporation (“Bendix”) for the U.S. Department of Energy in 1982. The Bendix study estimated uranium endowments at Copper Mountain of approximately 655 Mlbs eU₃O₈ to a depth of 600 feet within a broader “Assessment Area,” and 245 Mlbs eU₃O₈ to a depth of 600 feet within a more focused “Control Area.”
Following the staking update announced here, Myriad now controls approximately 62% of the Assessment Area and 80% of the Control Area, as defined in the Bendix report.
Myriad’s CEO, Thomas Lamb, commented: “Our recent geophysics identified the signatures of known uranium resources at Copper Mountain and illuminated an entirely new very large area to the east of known resources with a corresponding signature. See Figure 2 below and refer to our recent press release here. We quickly acquired this new large area and other areas suggested by the geophysics and our other data. Confidence is increasing that we now have one of the largest uranium projects in the United States. Based on results of our own initial drill program, we already have strong confidence in the core deposits and historic resources delineated by Union Pacific in the 1970’s. As uranium prices rise, a progressively larger share of our endowment will transition into economic viability, offering strong leverage to the steadily increasing price of uranium.”
The Bendix endowment figures are historical estimates and are not current mineral resource estimates prepared in accordance with NI 43-101 standards.
The focus will now shift to verification of anomalies identified through the interpretation of the high-resolution geophysical surveys completed in December 2025, followed by exploration drilling.
