Geologic district: Eastern Thelon Basin
Deposit object located: drill hole
Commodities: U
Geological ages: Late Paleoproterozoic (mineralization)
Middle Mesoproterozoic (mineralization)
Regional tectonic structure: linear feature (fault-controlled 20 km linear trend hosting 7 uranium deposits, striking NE and gently convex to the NW, between the Thelon and Sissons Lake faults) Tectonic structure name: Kiggavik Trend
fault (ENE-trending normal fault with downfaulted Thelon Formation on the north side against the basement on the south side; parallels the Sissons Lake fault) Tectonic structure name: Thelon fault
fault (ENE-trending normal fault with downfaulted sub-Thelon paleosol on the north side against the basement on the south side; parallels the Thelon fault) Tectonic structure name: Sissons Lake fault
Deposit shape: zone of two lenses
Deposit dimensions:length: 125 metre
width: 60 metre
depth: 230 metre
Qualified comments: (Applies to: discovery and development) Discovered in late 1980s; located 4 km SW of the Kiggavik Main zone. Drilling done until 1990 suggested possible additional resources in the order of those reported above. There has been no further drilling done since.

(Applies to: mineralization) The mineralization occurs in two adjacent lenses or blocks: one bottoms at about 160 m depth and the other narrower one plunges NNW to 330 m and is open at depth. Drill indicated resources of 1650 t U in 0.717 Mt grading 0.23 % U.
