Abstract: Lithium resources of the Yellowknife area are well documented in the published literature and in the records on file with the Mineral Resources Division, Canadian Department of Energy, Mines and Resources, Ottawa. The significant deposits occur as steeply dipping tabular, unzoned pegmatite dikes of Pre-Cambrian age dated at 2200 million years. The principal lithium mineral is spodumene. The numerous pegmatites are localized in metamorphic aureoles of knotted schists associated with granitic intrusions. Detailed mapping and surface sampling of fourteen properties within the district has demonstrated the presence of 49,000,000 tons of rock to a depth of 152m (500ft) having an average grade of 1.40% Li2O. These resources could be developed if and when market conditions place a strain on available supplies. Numerous other smaller or lower grade pegmatites exist throughout the district.
