VANCOUVER, BC - Marvel Discovery Corp. (TSX-V:MARV)(Frankfurt:O4T1)(MARVF:OTCQB); (the 'Company') is pleased to announce it has entered into an option agreement to acquire two large claim groups the ('KLR' and 'Walker') from an arm's length party. This positions Marvel in a highly advantageous position along the Key Lake fault adjoining both Cameco and Fission's property boundaries. The two claim groups collectively cover 14,190 hectares along the East, North and Northwestern directions.

The project lies within the Wollaston-Mudjactic Transition Zone ('WMTZ') of the eastern Athabasca Basin which is host to the highest-grade uranium mines in the world including:

Cigar Lake1, 50% owned by Cameco, which hosts 152 million pounds (lbs) of U3O8 at 15.4% U3O8

McArthur River2, 70% owned by Cameco which hosts 392 million lbs of U3O8 at 6.58% U3O8

Wheeler Project3, 90% owned by Denison Mines which hosts 109 million lbs of U3O8 in two deposits averaging 11.23% U3O8

The KLR, first claim group consists of 3,595 hectares (ha) and is contiguous to the former producing Key Lake Uranium Mine. The Key Lake Deposit consisted of two mineralized zones which historically produced a total of 4.2 million tonnes of product at an average grade of 2.1% U3O8 (Harvey, 1999). The Key Lake Property is now host to the Key Lake Mill, owned, and operated by Cameco which processes ore from the McArthur River uranium deposit.

The Walker Property, second claim group covers an area of 10,595 ha and is contiguous to Fission 3.0 Hobo Lake uranium properties. Hosted within WMTZ, the Walker Property lies along the Key Lake Shear Zone and hosts 10 uranium showings and multiple unexplored EM targets. Both properties are easily accessible by highway. Exploration to date on the Properties has been limited.

These 2 claims groups are in addition to Marvel's recent acquisition of the Highway North Project and are directly tied on to the North and South property boundaries within the same WMTZ corridor which covers an area of 2,573 ha (See Press Release Feb 28, 2022) Marvel now has a controlling interest in the camp totaling 16,763 ha.

We are extremely fortunate to have acquired the KLR and Walker claim groups being directly tied on to the north and south of our recently acquired Highway North Project. This brings our new total to over 16,000 hectares along a trend that hosts some of the highest-grade uranium mines in the world. Being next door to the former Key Lake Uranium Mine and Cameco's Key Lake Mill is highly strategic move as we advanced the project. This corridor along the Key Lake Shear Zone represents tremendous opportunity in mimicking the success of basement-hosted uranium deposits found on the western side of the Athabasca Basin like NexGen Energy's Arrow Deposit.' Mr. Karim Rayani, President & Chief Executive Officer Commented.

Regional Geology and Mineralization

In Saskatchewan, uranium deposits have been discovered at, above, and up to 300m below, the Athabasca Group unconformity within basement rocks. Mineralization can occur hundreds of meters into the basement or can be up to 100m above, in Athabasca Group sandstone. Typically, uranium is present as uraninite/pitchblende that occurs as veins and semi-massive to massive replacement bodies. Mineralization is also spatially associated with steeply-dipping, graphitic basement structures and may have been remobilized during successive structural reactivation events. Such structures can be important fluid pathways as well as structural or chemical traps for mineralization as reactivation events have likely introduced further uranium into mineralized zones and provided a means for remobilization
