The discovery hole was announced on Novemwith drill hole PLS12-022, from what is now referred to as the R00E zone. Through successful exploration programs completed to date, Triple R has evolved into a large, near surface, basement hosted, structurally controlled high-grade uranium deposit. From west to east, these zones are: R1515W, R840W, R00E, R780E and R1620E. PLS Mineralized Trend & Triple R Deposit Summary: Uranium mineralization of the Triple R deposit at PLS occurs within the Patterson Lake Conductive Corridor and has been traced by core drilling over ~3.18 km of east-west strike length in five separated mineralized "zones" which collectively make up the Triple R deposit. Previously reported Inferred mineralization totaling 1.24 Mlb U3O8 (<1.0% of total resource) contained within the Halo domain (901) have been excluded from the current May 17, 2022, Mineral Resources estimate as this zone does not meet CIM (2014) definition criteria for Reasonable Prospects for Eventual Economic Extraction (RPEEE) based on an underground mining only scenario. The R780E_HG domain consists of several lenses within the R780E_MZ and, when combined, the two zones account for approximately 68% of the total resources at Triple R. The zones are those areas traditionally referred to by Fission Uranium in press releases and on its website and are generally defined by differences in location with respect to local grid easting. Mineral Resources are inclusive of Mineral Reserves. Gold grades were also estimated and average 0.61 g/t for the Indicated Mineral Resources and 0.44 g/t for the Inferred Mineral Resources. Estimated grades are based on chemical assays only. Inferred Mineral Resources total 0.64 Mt at an average grade of 1.10% U3O8 for a total of 15.4 Mlb U3O8. At a COG of 0.25% U3O8 for Mineral Resources potentially mineable by underground methods, Indicated Mineral Resources total 2.69 Mt at an average grade of 1.94% U3O8 for a total of 114.9 Mlb U3O8. The Triple R resource database includes 17,509 density measurements of which 15,920 were used in the resource estimation. Hard boundaries were used between domains. Block densities were estimated from the density measurements using inverse distance cubed (ID3) and a similar search strategy as used for uranium grade. Estimated block model grades are based on chemical assays only. The threshold grade levels were chosen from the basic statistics and from visual inspection of the apparent continuity of very high grades within each domain, which indicated the need to limit their influence to approximately half the distance of the main search. To reduce the influence of high grade composites, grades greater than a designated threshold level for some domains were restricted to a search ellipse dimension of 25 m by 25 m by 5 m (high yield restriction). Most search ellipse dimensions were 50 m by 50 m by 10 m for a 5:5:1 anisotropic ratio. Announces the Results of an Updated Independent Resource Estimate for the Triple R Deposit
