Confirmation Of Extensive High-Grade Uranium Mineralization At Canning Deposit

VANCOUVER - Myriad Uranium Corp. reported on chemical assay (U3O8) grades from 8 boreholes drilled in late 2024 at the Copper Mountain Uranium Project in Wyoming. Chemical assays (U3O8) have been compared against the previously reported equivalent spectral gamma probe uranium results (eU3O8) and confirm extensive high-grade uranium mineralisation at the Canning Deposit. Furthermore, certain U3O8 intervals are higher, and lower, than their previously reported e U3O8 grades, indicating secular disequilibrium is present in the system. Using a 1,000 ppm cut-off, the U3O8 grades (from chemical assay) reported here are on average 50% higher than previously-reported eU3O8 grades (equivalent gamma probe grades) over the same intervals. Using a 200 ppm cut-off, they are on average 24% higher. These increases relative to probe grades are consistent with assays of the first 20 boreholes the Company reported in March. Results from the remaining 6 boreholes are pending and will be reported in due course.

Using a 200 ppm U3O8 cut-off, chemical grades are on average 24% higher than previously-reported equivalent (spectral gamma probe) uranium grades. Using a 500 ppm cut-off, the average grades are 43% higher, and using a 1,000 ppm cut-off, average grades are 50% higher. There is both positive and negative variance (disequilibrium).

Thomas Lamb, CEO, said, "These are excellent results which level up the Copper Mountain project. Confirmed grades average significantly higher than the equivalent gamma probe uranium grades and suggest Union Pacific may have taken a conservative approach to accounting for disequilibrium at Copper Mountain. This may have positive implications for historic resource estimates and grades. I mentioned in our previous release relating to assays that it is possible a significant volume of uranium mineralisation was not detected at Copper Mountain by the 1970-era gamma probes, which would be very exciting for the project. But also potentially very significant is what has been emphasised by this group of assays, which is that higher-grade zones are on average 50% more uraniferous than previously thought. This could have supportive implications for future resource estimation and mine planning, for example. However this must be treated as speculation."
