Marvel Drills Three Holes, Expands Drill Program to 1,400 Meters at KLR-Walker Uranium Project, Athabasca Basin

VANCOUVER, March 14, 2023 - Marvel Discovery Corp. (TSXV:MARV)(Frankfurt:O4T)(OTCQB:MARVF); ("Marvel" or the "Company") is pleased to provide an update on the inaugural diamond drilling program at the DD and Highway Zone within the KLR-Walker Uranium Project ("the Property") in the Athabasca Basin (Figure 1). The drill program was originally planned for 1,000m and has since been expanded to 1,400m. To date, 3 drill holes have been completed for a total of 684m.

Holes KLR23-01 and KLR23-02 targeted a previous 2015 backpack drill hole that intersected 1.96% U over 29cm at the Highway Zone. Hole KLR23-01 recorded a peak of 12,000 cps over a 4 m interval of anomalous gamma-ray readings (Figure 2). Drill hole KLR23-03 was drilled at the DD Zone 1.5 km north of the Highway Zone targeting historic drill holes DD-03, DD-16, and DD-21 where in 2015 a backpack drill hole intersected 1.57% U over 4 cm. The DD Zone was first explored and outlined via surface trenching in 1970.

Commentary

"We are very excited with the progress to date; the first indications are pointing to success after only 3 drill holes. We have expanded the current drill program from 1,000 meters to 1,400 meters and look forward to reporting on the results. Further detection from Gama Probe surveys also shows positive detection readings," stated Karim Rayani, President, Chief Executive Officer and 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 3). 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.
