Charlot Lake

Northern Athabasca Basin, Covering approx. 55.5sq.km

The Charlot Lake property is 55.5 sq. km. in size and located north of Uranium City, Saskatchewan. The property contains four uranium showings last explored in the 1970s offering the chance to apply modern exploration technology to develop the property.

Peacock Showing

The showing area is underlain by a northwest-trending sequence of quartzites in contact with gneisses. The radioactivity occurs in a pink to red, medium to coarse grained feldspar-garnet-quartz rock close to the sharp southeast contact with a thick sequence of strongly gossanous pyritic and sericitic quartzites. The source of the radioactivity was not identified, but is believed to be due to small disseminated grains of uraninite. Chip samples taken from the showing have returned assays up to 0.8% U3O8 and 0.12% MoS2.

50-TT-10 Uranium Occurrence

Consists of uraninite in the scarp of a shear zone that separates a mafic unit of the paragneiss sequence from a granite gneiss body. The strike of the rocks is northeast. The showing was worked in 1952 by Goldfields Uranium Mines Ltd. Red alteration was noticed in the feldspars which were coarsely crystalline near the high gamma-counts. A small pit sunk near the scarp wall exposed higher radioactivity and some uranium staining. No assay results were reported.

Charlot Lake Uranium Showing

Occurs in a northeast-trending, medium-grained quartz-feldspar pegmatite which is approximately 183m long by 61m wide. A radioactive, finely-disseminated light brown resinous mineral is present in the pegmatite. A weak yellow oxide stain is common on the surface. This showing is one of several bodies and lenses of pegmatite which run in a broad zone from Gwillim Lake to the northeast of Charlot Lake. The area underlying this broad zone is a granite and granite gneiss commonly containing bands or lenses of amphibolite or biotite. The showing was diamond drilled and samples from the drill holes returned assays of up to 0.023% U3O8 over 3.2m. Approximately 800m SW of the showing another pegmatite occurrence has been noted. This area is underlain by similar geology. High radioactivity and yellow staining has been found in the area.

Arty Lake Showing

The area is underlain by a northeast-trending sequence of granite and paragneiss enclosing a thin conformable band of amphibolite. A narrow overburden filled depression, which separates granite and amphibolite, forms a well-defined topographic lineament that is presumed to mark the trace of a persistent strike fault. In places, the wall rocks are iron-stained and radioactive. The showing consists of a 244m long mineralized zone with some historic reports suggesting that the zone extends considerably. Radioactivity appears to be restricted to alkali-felspar granite in a fracture zone which occurs in the contact between the granite and amphibolite. Diamond drilling was completed over the mineralized zone and the drill holes graded an average of 0.15% U3O8 across 51.52m along a strike length of about 150m. One deeper hole (#10) intersected 1.52m grading 1.65% U3O8.
