New resource estimate will be instrumental in updating life of mine and other economics in the Feasibility Study

KELOWNA, Sept. 12, 2022 - Fission Uranium Corp. ("Fission" or "the Company") is pleased to announce the results of an updated independent resource estimate for the Triple R deposit, which includes the R1515W, R840W, R00E, R780E and R1620E zones at its 100% owned, Patterson Lake South (PLS) property in Canada's Athabasca Basin region. Total Indicated tonnes have increased by ~21.3% (~472,000 tonnes) compared to the previous Mineral Resource (dated September 19, 2019), with an associated increase of approximately 12.3% in contained U3O8 and a minor decrease in grade from 2.10% U3O8 to 1.94% U3O8. The new, larger resource is primarily due to the successful infill drilling programs on the R780E and R840W zones from 2019 to 2021 and will be fundamental to the Feasibility Study (FS), including life of mine (LOM) calculations and processing schedule.

Ross McElroy, President and CEO for Fission, commented, "Fission's resource growth program has been a resounding success. The increased resource estimate of the Triple R deposit at PLS will play an important role in the calculations used for the feasibility study, the results of which are expected by year end. It's important to note that much of the growth has come from the R840W zone, the majority of which is now classified as Indicated, which will allow for inclusion in the new FS mine plan. In terms of further growth, the deposit remains open in multiple directions, and we do of course have another two mineralized zones along trend which are still classified as primarily Inferred resources."

Resource Estimation Methodology

The updated Mineral Resource estimate was completed by SLR Consulting (Canada) Ltd. "SLR" - a recognized independent consulting firm with significant resource estimation experience in high-grade Athabasca uranium deposits. Of the total 838 drill holes drilled on the PLS Property, 696 drill holes totaling 213,969 m of drilling were used in the Mineral Resource estimate. The wireframe models representing the mineralized zones are intersected in 436 of 686 drill holes.

As part of advanced stage studies for the Triple R deposit, Fission Uranium resumed infill drilling programs at R780E and R840W with the intention of upgrading certain high priority areas from Inferred Mineral Resources to Indicated Mineral Resources. Of the 175 drill holes completed since the 2019 estimate, 46 infill exploration and three geotechnical drill holes, totalling 14,304 m, targeted the high grade (HG) and main low grade (LG) domains in the R780E and R840W zones (24 drill holes totalling 8,180 m and 25 drill holes totalling 6,124 m, respectively) with the objective to upgrade Inferred Mineral Resources to the Indicated classification, and improve the geotechnical understanding of the zones.

SLR interpreted and constructed low grade wireframe models using a nominal COG of 0.05% U3O8 and a minimum core length of one metre. SLR considers the selection of 0.05% U3O8 to be appropriate for construction of mineralized wireframe outlines, as this value reflects the lowest COG that is expected to be applied for reporting of the Mineral Resources in an underground operating scenario and is consistent with other known deposits in the Athabasca Basin.

Sample intervals with assay results less than the nominated cut-off grade were included within the mineralized wireframes if the core length was less than two metres or allowed for modelling of grade continuity. Wireframes of the High Grade (HG) domain were created using a grade intercept limit equal to or greater than one metre with a minimum grade of 5% U3O8, although lower grades were incorporated in places to maintain continuity and to meet a minimum thickness of one metre.

SLR built the wireframe models using 3D polylines on east looking vertical sections spaced 15 m apart. Infill polylines were added to accommodate for irregular geometries. Polylines were "snapped" to assay intervals along the drill hole traces such that the sectional interpretations "wobbled" in 3D space. Polylines were joined together in 3D using tie lines and the continuity was checked using a longitudinal section and level plans. Extension distance for the mineralized wireframes was half-way to the next hole, or approximately 25 m vertically and horizontally past the last drill intercept.

Grade interpolations for U3O8 and gold were carried out using ID3 in a single pass with a minimum of two to a maximum of seven composites per block estimate. The search ellipse orientation varied slightly by domain. Hard boundaries were used to limit the use of composites between domains. Most search ellipse dimensions were 50 m by 50 m by 10 m for a 5:5:1 anisotropic ratio.

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). 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. Estimated block model grades are based on chemical assays only.

Block densities were estimated from the density measurements using inverse distance cubed (ID3) and a similar search strategy as used for uranium grade. Hard boundaries were used between domains. The Triple R resource database includes 17,509 density measurements of which 15,920 were used in the resource estimation.

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. Inferred Mineral Resources total 0.64 Mt at an average grade of 1.10% U3O8 for a total of 15.4 Mlb U3O8. Estimated grades are based on chemical assays only. 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. Mineral Resources are inclusive of Mineral Reserves.

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. 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.

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.

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. From west to east, these zones are: R1515W, R840W, R00E, R780E and R1620E. Through successful exploration programs completed to date, Triple R has evolved into a large, near surface, basement hosted, structurally controlled high-grade uranium deposit. The discovery hole was announced on November 05, 2012 with drill hole PLS12-022, from what is now referred to as the R00E zone.

The R1515W, R840W and R00E zones make up the western region of the Triple R deposit and are located on land, where overburden thickness is generally between 55 m to 100 m. R1515W is the western-most of the zones and is drill defined to ~90 m in strike-length, ~68 m across strike and ~220 m vertical and where mineralization remains open in several directions. R840W is located ~515 m to the east along strike of R1515W and has a drill defined strike length of ~430 m. R00E is located ~485 m to the east along strike of R840W and is drill defined to ~115 m in strike length. The R780E zone and R1620E zones make up the eastern region of the Triple R deposit. Both zones are located beneath Patterson Lake where water depth is generally less than six metres and overburden thickness is generally about 50 m. R780E is located ~225 m to the east of R00E and has a drill defined strike length of ~945 m. R1620E is located ~210 m along strike to the east of R780E, and is drill defined to ~185 m in strike length.

The Company completed and filed a prefeasibility study ("PFS") on November 07, 2019 titled "Pre-Feasibility Study on the Patterson Lake South Property Using Underground Mining Methods, Northern Saskatchewan, Canada". The report summarizes the Pre-Feasibility Study ("UG PFS"), which outlines an underground-only mining scenario for PLS which to date has only considered the R00E and R780E zones.

Mineralization along the Patterson Lake Corridor trend remains prospective along strike in both the western and eastern directions. Basement rocks within the mineralized trend are identified primarily as mafic volcanic rocks with varying degrees of alteration. Mineralization is both located within and associated with mafic volcanic intrusives with varying degrees of silicification, metasomatic mineral assemblages and hydrothermal graphite. The graphitic sequences are associated with the PL-3B basement Electro-Magnetic (EM) conductor.

Patterson Lake South Property

The 31,039 hectare PLS project is 100% owned and operated by Fission Uranium Corp. PLS is accessible by road with primary access from all-weather Highway 955, which runs north to the former Cluff Lake mine.
