The Crescent Lake Lithium Project is located 250 km NNE of Thunder Bay, north of Lake Superior in Ontario, Canada. The project features two prospective areas: Falcon Lake and Zigzag. Additional claims covering the under-explored area between clusters of known spodumene pegmatites are also within the Crescent Lake Project.
The Crescent Lake lithium deposits are hard rock, ‘complex-type/spodumene sub-type’ pegmatite deposits. The prospective areas are defined by two phases of drilling: historic diamond core drilling, undertaken in the 1950s; and limited modern diamond drilling completed in 2011, plus trench sampling.
The pegmatites also feature elevated tantalum and are geologically comparable to the lithium tantalum pegmatite being mined at Tanco in Manitoba, Canada and Greenbushes in Western Australia.
The known deposits outcrop and are potentially suitable for open-cut mining.
Highlights of historic drilling at the Crescent Lake Lithium Project include:
8.1m at 1.48% Li₂O from 2.7m in drill hole W-3
10.5m at 1.15% Li₂O from 34.5m in drill hole W-9
14m at 0.99% Li₂O from 69.3m in drill hole CO-10-001
7m at 1.07% Li₂O from 55.3m in drill hole CO-10-002
11m at 1.10% Li₂O from 39.4m in drill hole CO-10-003
6.1m at 1.08% Li₂O from 12.4m in drill hole CO-10-007
