Key Lake Road Projects
Key Points of Interest
- The claim block area straddles the Archean/Aphebian unconformity and is underlain to the west by Archean granite gneiss and to the east by Aphebian-aged metasediments of the Wollaston Fold Belt. The metasedimentary rocks are composed of pelitic schists and gneisses (some of which are graphite-bearing), meta-arkoses, and calcareous units, including calc-silicates and calcareous meta-arkoses. They are cut by pegmatitic bands and lenses that are generally concordant with strike.
- Airborne VTEM surveys have traced an EM conductor corridor that runs at least 50 km along the length of the property.
- The historic Karpinka Lake Uranium Showing occurs within the north end of the property, which consists of a series of five discontinuous low grade zones of stratabound uranium mineralization. Of these, the George Zone displays a strike length of 2.2 kilometres and a width varying from 1.0 to 3.0 metres. Disseminated uraninite occurs within a sillimanitic, pyritic meta-arkose horizon. Adjacent to the east is the Karpinka Lake radioactive boulder train, a 1.2 kilometre long fan-shaped collection of over 100 boulders containing disseminated uraninite and uranothorite and assaying up to 3525 ppm uranium. Drilling up-ice by Getty Minerals returned up to 0.166% U3O8 over 1 metre. A source for the boulders has not been determined.
- Prospecting by Forum Uranium Corp. in 2004/2005 led to the discovery of several more uranium mineralized zones along the length of the property, associated with moderate to strong conductive zones attributed to graphitic pelitic gneisses unconformably overlying Archean granitic gneisses. Drilling within these zones included DDH DD-08 which returned up to 313 ppm uranium over 0.3 metres within a tectonized graphitic pelitic gneiss, which was encountered from 5 metres depth to 145 metres depth. Grab sampling in the southern part of the property has returned up to 2% U3O8 in calc-silicate outcrops.
- The Key Lake Road runs up the entire length of the property, providing easy access to all areas.
- The exploration target is high grade basement hosted root zone uranium mineralization associated with an eroded unconformity-type uranium deposit.
