The mineralization in ZZ-10-79 could be the unconformity manifestation of basement hosted ura- nium at depth • The shallow depth to the unconformity reduces exploration costs and increases the options available for mining should a deposit be found Next Steps • Given the lack of surficial geochemical data and relatively shallow sandstone cover, a soil sam- pling program could flag overlooked areas along the magnetic low corridor • Reinterpret historical drilling to determine the best area to test for down-dip extensions of the known mineralization 2Z Lake Claim Summary Claim Hectares Effective Date Annual Expiry Date Assessment S-110251 52 Nov. 24, 2008 $1,300 Dec. 24, 2023 S-110253 174 Nov. 24, 2008 $4,350 Dec. 24, 2022 S-110254 41 Nov. 5, 2008 $1,025 Dec. 24, 2023 S-110255 87 Nov. 24, 2008 $2,175 Dec. 24, 2022 Total 354 $8,850 (2% NSR & 2% GORR on claims).
