Lithology Comments

Jun 16, 2020 (Therese Pettigrew) - The occurrences are hosted by east-trending metasediments, south of the Quetico Fault. The metasediments consist of wacke and phyllite have been intruded by ultramafic stocks and minor felsic porphyries (Schnieders and Dutka, 1985).

Mineralization Comments

Jun 16, 2020 (Therese Pettigrew) - A series of quartz veins are situated conformably within the hosting east-trending metasedimentary belt. Although exposure was poor the veins appear to have a maximum width and strike length of l metre and 10 metres, respectively. They consist of white, sugary to milky quartz, contain no visible sulphides, and generally exhibit very limited evidence of shearing. Assay results on a single grab sample indicate only a trace of gold and silver. Approximately 3/4 kilometre east-northeast of these quartz veins, a small outcrop (5 metres by 10 metres) of coarse-grained (up to 1 centimetre crystals) pyroxenite or hornblendite was noted in a large swamp. No visible sulphides are present in the outcrop, however, due to the poor exposure, the size and potential of the intrusion was not determined. A grab sample assayed trace copper, 0.04 percent nickel, no platinum, and trace palladium. A coarse-grained (up to 1.5 centimetres) pegmatite dike was found on this property. This dike is about 7 metres wide and has an exposed strike length of 12 metres. It is composed of white quartz and feldspar and large (2 centimetres) "books" of muscovite. Assay results on a single grab sample indicated that lithium was not present (Schnieders et al., 1981)
