Preliminary Interpretation Of High-Resolution Geophysics At Copper Mountain

VANCOUVER – Myriad Uranium Corp. has completed preliminary interpretation of data from its large-scale, high-resolution airborne magnetic and radiometric survey flown over the Copper Mountain Uranium Project in December 2025.
CEO, Thomas Lamb, said, “All known historic uranium resources and almost all known targets at the Copper Mountain Uranium Project are located west of the major north-south structural corridor. They stand out in the violet signatures just west of the corridor, as you can see. However, in what is entirely new information, the overwhelming majority of radiometric anomaly points generated by our recent district-scale airborne survey occur in untested ground east of that structural corridor. As soon as we saw this result, we moved quickly to secure the eastern ground and last week we initiated systematic ground-truthing. Initial field inspections are returning elevated radiometric counts consistent with the airborne data, and we are encouraged by these early indications. We expect to provide details regarding our expanded land position shortly, followed by results from the ongoing validation program. This process will also provide additional targets for our phase 2 drill program planned to start in Q2.”
Known deposits are correlated with magnetic and radiometric signatures. Magnetic and equivalent uranium (eU) signatures are spatially coincident. Extensive radiometric anomalies occur across the district. Structural features together with these anomalies are consistent with the hydrothermal alteration model of mineralization control. Large number of new anomaly clusters have been identified in previously underexplored eastern extensions.
The combined magnetic and radiometric dataset supports the interpretation of a large hydrothermal system capable of hosting additional uranium mineralization beyond historically drilled areas. More than 100 anomaly points have been prioritized for field validation, the vast majority of which are located to the east of the north-south structural corridor.
In response to these developments, Myriad has now commenced with field work to ground-truth selected radiometric anomaly points. The aim of the field work is to: 1) Confirm the presence and intensity of anomalous uranium mineralization. 2) Characterize the geological setting, structural and alteration controls. 3) Assess the relative scale and continuity of anomalies. 4) Identify and refine priority drill targets. 5) Initial results are consistent with airborne anomaly responses.
