Key points of interest:

  • The Grease River shear zone traverses the southern part of the property, providing structural controls with potential for unconformity-hosted uranium mineralization.
  • The Bradley Showing outlined by CanAlaska Uranium in 2008 field work (up to 3.53% U3O8 in pitchblende veinlets within a mylonite/shear), is structurally controlled mineralization spatially related to the Grease River Shear Zone. This occurrence lies just outside the southwest property boundary. Two CanAlaska drillholes in 2011 undercut the showing and returned 0.022% U3O8/0.9m and 0.015% U3O8 / 0.5m between 15m and 30m below surface, within narrow intervals of quartz-carbonate-biotite +- pyrite stockwork and crackle brecciation.
  • A 30 km2 area surrounding North Tait Lake was found by SMDC to be highly anomalous in uranium in lake sediments (100ppm +), which led to a 1980 study that found 'in the order of' 900,000 kg total contained uranium within the study area (Roy and Earle 1980)(Peter Daubeny, 2010 Technical Report For The Grease River Project, Saskatchewan For CanAlaska Uranium Ltd.). Appx. 75% of this study area lies within the Perron Lake claims.

The Perron Lake property comprises 5 mineral claims totalling 17,025 ha located approximately 20km north of the edge of the Athabasca Basin and 40km northwest of the full service town of Stony Rapids Saskatchewan. Fission 3.0 holds 100% ownership of the property, which was originally acquired by staking in December 2013; a fourth claim was added to the property in January, 2014.


The Perron Lake area has been prospected since the 1920's, initially for gold, copper and nickel. Exploration for uranium commenced in the early 1970’s. Work carried out by Saskatchewan Mining Development Corp in the early 1980’s revealed elevated uranium concentrations within local lake sediments in an area centered on Tait Lake, and a preliminary bulk sample and resource study estimated 900,000 kg of uranium in local lake sediments.

Work proximal to the Perron Lake Property by CanAlaska since 2007 has outlined several outcrop and boulder uranium occurrences grading up to 3.5% U3O8 within granitic and gneissic lithologies.

Fission 3.0 commissioned a $265,000 7,986 km airborne high resolution magnetic and radiometric survey that completed in August 2015. Survey interpretation concluded that the project area is transected by several distinctive magnetic high linear features interpreted as Mackenzie diabase dikes. There are three distinct magnetic low zones in the project area. All areas have numerous interpreted cross-structural features.

  • Magnetic Low Zone A is located in the Train geologic domain. The magnetic fabric in this zone trends in a NE direction and suggests the possibility of long strike length conductive features.
  • Magnetic Low Zone B straddles the Train and Dodge domains. This may suggest a re-interpretation of the domain boundary. There is no clear indication of magnetic trend direction in this zone. Potential conductive features in this zone are expected to be of shorter strike length, which have been structurally disrupted.
  • Magnetic Low Zone C is located in the Tantato Domain. The magnetic fabric trends in the ENE direction and consists of bands of magnetic relative highs and lows. Potential conductive features in this zone are expected to be of long strike length.

The radiometric data identified 22 anomalous areas, where coincident elevated Total Counts (TC) and U_ppm were defined.

The frequency and geological diversity of the TC/U_ppm coincidence within the Perron Lake property are compelling. There is evidence of plutonic and non plutonic uranium associations.

Ground follow-up of the airborne survey results occurred during September 2015 with a  2 week prospecting program by a Fission 3.0 geological field crew. Site visits were made to 48 ground radiometric targets, and 14 rock samples taken for geochemical analysis.

Lithological mapping was not the priority of this program, but in summary the host rock consists largely of biotite and hornblende gneisses. Four domal structures are present, each with a granitic core. Brittle structures were not encountered, but are likely to be present in narrow zones along the major shear zones; all deformation seen was in the ductile realm. Rock in general is high in K, and the chemistry of the granites suggests a post-orogenic origin. Possible alkali metasomatic U targets are present at the dome margins and in host gneisses.

Total counts from ground spectrometer measurements varied from 150 to 17200 cps, with an average of 3000 cps. Three possibly anomalous uranium populations emerged, observed values ranged from 5 to 1,344 ppm uranium, with an average of 155 ppm. Uranium to thorium ratios ranged from 0.1 to 6.4 with a 1.6 average. The higher U/Th values may possibly represent U enrichment due to an igneous or sedimentary U enrichment in the protolith, enrichment during metamorphism, or during later tectonic/hydrothermal activity.
