![]() Hard boundaries were used between domains. Estimated block model grades are based on chemical assays only.īlock densities were estimated from the density measurements using inverse distance cubed (ID3) and a similar search strategy as used for uranium grade. 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. Hard boundaries were used to limit the use of composites between domains. The search ellipse orientation varied slightly by domain. Grade interpolations for U 3O 8 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. 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. Polylines were joined together in 3D using tie lines and the continuity was checked using a longitudinal section and level plans. Polylines were "snapped" to assay intervals along the drill hole traces such that the sectional interpretations "wobbled" in 3D space. Infill polylines were added to accommodate for irregular geometries. SLR built the wireframe models using 3D polylines on east looking vertical sections spaced 15 m apart. 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% U 3O 8, although lower grades were incorporated in places to maintain continuity and to meet a minimum thickness of one metre. 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. SLR considers the selection of 0.05% U 3O 8 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. SLR interpreted and constructed low grade wireframe models using a nominal COG of 0.05% U 3O 8 and a minimum core length of one metre. ![]() ![]() FISSION URANIUM DRILL RESULTS UPGRADEOf 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. 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.Īs 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. ![]() 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 U 3O 8 and a minor decrease in grade from 2.10% U 3O 8 to 1.94% U 3O 8. 12, 2022 /CNW/ - 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. New resource estimate will be instrumental in updating life of mine and other economics in the Feasibility Study ![]()
