Marvel Discovery pulls off stroke of genius amid arguably biggest uranium boom ever

Major expansion makes Marvel a direct neighbour of Cameco, Fission 3.0 and Baselode Energy

Marvel’s news-release from Marvel Discovery Corp. (TSX.V: MARV suddenly makes the $12 million market cap company a serious contender in the world-famous Athabasca Uranium Basin in Canada as Marvel greatly expanded its Highway Property by 14,190 hectares, now being a direct neighbour of uranium project developers Cameco Corp. (TSX: CCO; market cap: $14 billion), Baselode Energy Corp. (TSX.V: FIND; market cap: $84 million) and Fission 3.0 Corp. (TSX.V: FUU; market cap: $42 million).

In total, Marvel Discovery Corp. now owns more than 16,000 hectares (160 km2) in the heart of the Wollaston-Mudjactic Transition Zone (“WMTZ”) in the east of the Athabasca Uranium Basin, where some of the world´s highest grade uranium mines occur: Cigar Lake (50% Cameco; 152 million lbs uranium @ 15.4% U3O8), McArthur River (70% Cameco; 392 million lbs uranium @ 6.58% U3O8) and Wheeler (90% Denison; 109 million lbs uranium @ 11.23 U3O8). 

Marvel Discovery´s new property is located near the past producing Key Lake Uranium Mine, which produced a total of 4.2 million t @ 2.1 U3O8, and where Cameco´s Key Lake Mill, which processes uranium ore from the McArthur Uranium Mine, remains active. This proximity to a major uranium processing plant is of great strategic value to Marvel Discovery.
That a junior like Marvel Discovery has taken control of such a large and attractive property right next to the big players in the Athabasca Basin shows the negotiating skills of the management team, as the uranium price is currently in a strong uptrend and many publicly listed uranium companies are currently among the best performing commodity stocks.
Morgan Stanley expects a supply deficit of 40 million lbs uranium in 2022, which is one of the reasons the uranium price is booming: 

The uranium price is in a strong upward trend.

Uranium stocks around the world, especially with a focus on Canada´s Athabasca Basin, have been doing particularly well for some time, with an acceleration of the upward trend evident in recent weeks: 

Sentiment towards nuclear power plants has turned around in view of the sharp rise in energy prices, not only in Japan (see here) and the USA, but is undergoing a paradigm shift globally:

Today´s news-release from Marvel Discovery Corp:


March 29, 2022. Vancouver, B.C. – 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 U3Oat 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% U3O(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 (Jefferson, et al. 2007) (Figure 2).

The Triple R, Eagle Point, Cluff Lake and Arrow deposits are found within basement rocks of the Crystalline Granulite Domain in the western Athabasca Basin. The KLR and Walker properties lie within the basement rocks just south of the former Key Lake Mine within the WMTZ. Source Searchlight Resources.

Both Properties straddle the Key Lake Fault Zone, an important corridor for structurally controlled Athabasca Basin type uranium deposits. 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.


The Transaction

As consideration for the Option, the Company has agreed to pay the vendor (the “Optionee”) a total of $550,000 over a 4-year period and incur $1,500,000 in exploration expenditures by the 3rd anniversary date of the signed agreement. In addition, the Optionee will retain a of a 1.0% net smelter royalty (“NSR”), of which Marvel will have the right to purchase 100% of the NSR for $1,000,000.
