Marvel Signs Joint Venture Agreement With Carmanah Minerals on Its Walker Uranium Claims in the Athabasca Basin

" We are very pleased to have reached a Joint Venture agreement with Carmanah Minerals, after careful consideration this transaction made the most sense long-term for Marvel shareholders. This affords us the ability to work both the north and south claim blocks simultaneously, while further protecting our share capitalization. Marvel still holds a considerable area of influence and controls 100% of the KLR and Highway North Claims along the Key Lake Shear Zone which is home to some of the worlds highest grade uranium. This corridor represents tremendous opportunity in mimicking the success of basement-hosted uranium deposits found on the western side of the Basin like NexGen Energy's Arrow Deposit. We look forward to working with the team at Carmanah with the common goal of a Tier 1 Discovery." stated Chief Executive Officer Karim Rayani

The Walker and KLR Properties lie 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:

The WMTZ hosts the highest-grade uranium mines in the world including (Figure 1):

• Cigar Lake¹, 50% owned by Cameco, which hosts reserves of 221.6 million pounds (lbs.) of U₃O₈ at 16.7% U₃O₈
• McArthur River², 70% owned by Cameco which hosts reserves of 392 million lbs. of U₃O₈ at 6.91% U₃O₈
• Wheeler Project³, 90% owned by Denison Mines which hosts reserves of 109 million lbs. of U₃O₈ in two deposits averaging 11.23% U₃O₈.

Regional Geology and Mineralization

In Saskatchewan, uranium deposits have been discovered at, above and up to 300 metres below the Athabasca group unconformity within basement rocks. Mineralization can occur hundreds of metres into the basement or can be up to 100 metres 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).

Figure 2. Classic uranium deposits of the Athabasca Basin at the unconformity between the Athabasca sandstone and crystalline basement within the WMTZ. 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.

Marvel still controls 100% of the Highway North and KLR claims (Figure 3). These claim groups straddle the Key Lake fault zone, an important corridor for structurally controlled Athabasca-basin-type uranium deposits. The Arrow deposit⁴, 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 pounds of U₃O₈ at an average of 2.37% U₃O₈ and measured and indicated resources of 256.7 million pounds at an average grade of 3.1% U₃O₈. The Arrow deposit is the largest undeveloped uranium deposit in Canada.
