Pegasus Acquires USA Uranium Project






Pegasus Signs Option Agreement to Acquire 147 Lode Mining Claims in South Dakota, USA Covering a Non-NI 43-101 Compliant Historical Measured and Indicated Resource Containing 2,379,990 Lbs. U3O8 and a Historical Potential Resource Containing 1,440,000 Lbs. U3O8



Pegasus Resources Inc. (TSX-V: PEGA) (Frankfurt – OQS2) (OTC/Pink Sheet symbol: SLTFF) is pleased to announce the acquisition of 147 lode mining claims (approximately 3,037 acres) located on lands managed by United States Forest Service in Fall River County, South Dakota. Claims were optioned from Cowboy Exploration and Development, a Wyoming-registered LLC in an all-cash deal, US$1,500,000 for 100% ownership payable over three years (subject to TSX approval).


Mineralization is hosted within typical roll front–type deposits in the Cretaceous-age Fall River and Lakota formations. The contiguous claim block covers Uranium mineralization drilled by Union Carbide Corp (UC) in the late 1970’s.


Union Carbide-defined, non-43-101 compliant historical measured and indicated resources total 2,379,990 lbs. U3O8. Mineralization occurs in three areas and was evaluated by UC for conventional open pit and underground mining. Union Carbide resource calculations also report an additional potential resource based on geologic projection of the UC-calculated “measured and indicated resources” of 1,440,000 lbs. U3O8 proximal to the defined deposits (Cohan, 2004). Resource calculations are documented in UC and subsequent claimant reports and UC radiometric ore maps covering most of the reported mineralization.


UC delineated two unoxidized deposits (October Jinx and Viking) that are 350 ft. to 500 ft –deep and, based on historic depth-to-groundwater measurements (Cohan, 1984), are believed to lie below the water table. Mineralization is hosted in three sands of the lower Chilson member of the Lakota formation. Historical UC resources (“UC Mining Reserves”) were calculated using internal UC protocol for underground mining. Drill patterns were on 100 ft. and 50 ft. centers. Measured resources of deposits drilled on 50 ft. centers were calculated using the manually calculated Polygonal Block Method. Measured resources on 100 ft. drill spacing were calculated using a 300 tons per foot estimate per ore intercept. Indicated resources based on 100 ft. drill spacing were derived by subtracting the measured resources from the total resources calculated using the standard formula which relates the ratio of ore holes to total holes within the volume of the area of equally spaced drilling (Pinnick, 1982). Resources were calculated using a 0.06% U3O8 cut-off grade and a grade X thickness (GT) cut-off of 0.30. Dilution due to minimum underground mining widths and grade distribution were also incorporated (Pinnick, 1982).


Underground Mining Resources (historical, non-43-101 compliant)


Mine Unit   Tons %U3O8 Lbs. U3O8
October Jinx Measured 615,700 0.133 1,187,400
  Indicated 218,000 0.133 453,000
Viking Measured 166,000 0.101 336,000
Total (M+I) Resources (Lbs. U3O8)   1,977,000


UC drilling also delineated at least eight small, conventional open-pit mining (oxidized) deposits, in the Fall River and Lakota formations. Drill patterns were on 50 ft. centers and measured resources were calculated for open pit mining at a 0.04 % U3O8 cut-off and a minimum 0.08 GT (Pinnick, 1982).


Open Pit Mining Resources (historical, non-43-101 compliant)

Mine Units Combined Tons %U3O8 Lbs. U3O8
Long Mountain (6 units) and 323,800 0.062 402,990
Fox River (2 units)      
Total Measured Resource (Lbs. U3O8)   402,990


The claims are located approximately 5.5 Kilometres southwest of the enCore Energy Corp., Dewey–Burdock ISR Uranium deposit which is also hosted in the Chilson member sandstones. The Dewey–Burdock deposit contains a measured and indicated resource of 7.39 M tons at an average grade of 0.116 %U3O8, or 17.12 M lbs. U3O8 (Azarga 43-101 Technical Report PEA, 2019). The project is currently in advanced–stage mine permitting.


Pegasus is planning to conduct drilling programs following the acquisition of additional public and already identified privately owned data packages. Drilling objectives are to confirm historical UC results, produce an up-dated 43-101 compliant resource, perform aquifer tests for ISR amenability, and to explore for additional mineralization along projected trends.
