- Quetico Subprovince comprises a sequence of metamorphosed sedimentary rocks.
- The sedimentary rocks include metasedimentary and metavolcanic rocks of the Quetico Group and metasedimentary rocks of the English River Group.
- Lithium mineralization in the Quetico Subprovince is hosted in spodumene-bearing pegmatites that intrude the metasedimentary rocks of the Quetico and English River Groups.
The Quetico Subprovince has seen renewed interest in lithium exploration in recent years, with several companies actively exploring for lithium-bearing pegmatites in the area.
- The pegmatites occur in swarms and are typically coarse-grained, ranging from several meters to hundreds of meters in thickness.
- The lithium grades in the pegmatites are variable and range from a few hundred ppm to over 3% Li2O.
- The lithium mineralization in the pegmatites is typically associated with quartz, albite, and spodumene, and occurs as disseminations, veins, and pods.
