Whabouchi/ Nemaska Lithium (Li)
The Whabouchi Lithium Deposit of Nemaska is located near the town of Nemiscau, in the James Bay Region, Province of Quebec, approximately 300 km NNW of Chibougamau. The property is located in the NE part of the Superior Province in the volcano-sedimentary Lac des Montagnes Formation wich consists of metasediments and mafic to ultramafic amphibolites which are intruded by a network of NE-SW parallel vertical pegmatite dykes some of which reach up to 130 meters wide.
The most important mineralized pegmatite swarm runs for 1.3 km and is known to extend more than 300 meters deep. Spodumene crystals can have up to 30 cm long.
The mineral resources calculated with a cut-off grade of 0.6% Li2O were estimated at:
► Measured and Indicated categories: 37,356,000 tonnes at 1,48% Li2O.
► Inferred category: 6,687,000 tonnes at 1,37% Li2O.
Geologica was involved in the early stage prospection, reconnaissance geological mapping and sampling of the pegmatites and also for nearby hosted deposits of Ni-Cu intrusive related base metals.
