Marvel Discovery Corp. announced a Phase II follow-up drilling program at the DD and Highway Zone within the KLR-Walker Uranium Project in the Athabasca Basin. The Phase II drill program would consist of 4 holes totaling approximately 2,400 m. The start date of the program has yet to be determined.

A total of 1,343 m was completed through 6 diamond drill holes in the spring of 2023 which intersected 841 ppm U3O8 over 1.07 m at the DD Zone and 553 ppm U3O8 over 1.89 m at the Highway Zone. All uranium mineralization encountered in the Phase I drill program consisted of stringer mineralization coincident with a regional scale fault, the Key Lake Shear Zone. The Key Lake Shear is part of the Wollaston-Mudjactic Transition Zone of the eastern Athabasca Basin.

The WMTZ hosts the highest-grade uranium mines in the world. Drilling during the Phase II program will target uranium mineralization down dip within the fault zones. Like its neighbor to the west, the Arrow Deposit, owned by NexGen Energy lies along a similar structural corridor as the Marvel properties.

The Arrow Deposit, which has undergone a Positive Feasibility Study with robust economics contains Probable Reserves of 239.6 million lbs of U3O8 at an average of 2.37% U3O8 and Measured and Indicated Resources of 256.7 million lbs at an average grade of 3.1% U3O8. The Arrow Deposit is the largest undeveloped uranium deposit in Canada.
