Nov 02, 2007 (Mark Puumala) - This discretionary occurrence is based on the reported presence of the lithium-bearing amphibole holmquistite in granitic rocks at this location by Ayres (1972). The mineralization is reported to have been found within an approximately 800 m to 1600 m northwest-trending pegmatite-bearing zone in the granitic batholith located south and west of Setting Net Lake (Ayres 1972). This zone is reported to be located immediately to the north of the Bear Head fault zone.
