VANCOUVER, April 19, 2023 - Marvel Discovery Corp. (TSXV:MARV)(Frankfurt:O4T)(MARVF:OTCQB); ("Marvel" or the "Company") is pleased to report the completion of its inaugural diamond drilling program at the DD and Highway Zone within the KLR-Walker Uranium Project ("the Property") in the Athabasca Basin (Figure 1).

Commentary

"Marvel is pleased to report on the completion of our inaugural drill program on the Walker-KLR Uranium Project. Anomalous CPS values were encountered in every hole with impressive downhole peak probe values. We look forward to receiving assays along this favourable structurally related uranium trend, a key ingredient to the large uranium deposits of the Athabasca Basin." stated Karim Rayani, President & Chief Executive Officer, Director.

The KLR-Walker Property

The Property is located within the Wollaston-Mudjactic Transition Zone ("WMTZ") of the eastern Athabasca Basin. The WMTZ hosts the highest-grade uranium mines in the world (Figure 2). The DD Zone within the Highway Project straddles the Key Lake Shear Zone, an important fault for structurally controlled Athabasca Basin type uranium deposits.

The DD Zone is proximal and along strike to Fission 3.0 Hobo Lake uranium properties. Hosted within WMTZ, the DD Zone lies along the Key Lake Shear Zone and hosts 10 uranium showings and multiple unexplored EM targets.

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 Deposit¹, 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.
