Myriad Uranium Corp. has intersected 50 mineralized intervals exceeding 100 ppm equivalent uranium (eU3O8) across four initial drill holes totaling 716.6 metres at the Lucky Cliff target within the Copper Mountain Uranium Project in Wyoming.

The longest mineralized interval returned 19.96 metres at 269 ppm eU3O8 from 18 metres downhole in hole LUC0004DD, which included a higher-grade intercept of 1.98 metres at 866 ppm eU3O8. Across all four boreholes, the highest individual grade intercepted reached 1,336 ppm eU3O8.

Lucky Cliff is located about 2,000 metres north of the Canning deposit along the Myrtle's Fault trend. Because Lucky Cliff lies outside any area with a historical resource or endowment estimate, any mineral resource defined there in the future will be new and incremental to the Copper Mountain endowment.

Myriad holds a 75% interest in Copper Mountain and has an agreement to acquire the remaining 25% via Rush Rare Metals Corp. The broader project hosts a historical resource estimate of 26.63 million pounds of eU3O8 contained in 44.1 million tonnes at an average grade of 171 ppm eU3O8. A qualified person has not done sufficient work to classify the historical estimate as current mineral resources or mineral reserves.

“These are encouraging preliminary radiometric results from a new area in the north of our recently expanded Copper Mountain Project Area and outside historical estimate boundaries. Mineralization occurs at shallow depths with some remarkably long intervals. All four boreholes encountered significant equivalent uranium mineralization.”

— Thomas Lamb, CEO

The current findings are based on preliminary gamma probe equivalent uranium results derived from downhole logging by Century Geophysical and remain subject to laboratory verification. Myriad expects to receive chemical assay results to verify the radiometric data and plans to continue its Phase II drill program at Copper Mountain.
