Dec 07, 2005 (K R Kettles) - The area is underlain by felsic tuff striking roughly east-west, and by a serpentinized ultramafic intrusion. Trenches have been cut into both rock types; the trenches in felsic tuff reportedly contain gold, silver, pyrite, chalcopyrite, and antimony (Riley, 1975).

Mar 22, 2012 (K R Kettles) - The felsic tuff contains gold, silver, with minor pyrite, chalcopyrite, and stibnite. Grab samples collected in 1969 assayed 0.01 opt Au, tr Ag, 0.33% and 0.27% Cu, 0.1% Sb, and trace Mo. consist of narrow pyrite, chalcopyrite bearing quartz veins with in a brecciated felsic volcanic unit. Channel samples from 2003 returned values up to 4.40 g/t Au over 0.5m. Visible gold occurs in several veins and grab samples have yielded ip to 22.72 g/t Au. 2005 single drill hole consisted of stronglt altered felsic volcanics with up to 5% chalcopyrite. Several gold values were returned (>100 ppb) copper 0.2%
Jul 31, 2020 (Therese Pettigrew) - The 991 showing consists of narrow (0.5-20 cm) pyrite, chalcopyrite-bearing quartz veins within a brecciated felsic volcanic unit. The veins are approximately 20 m from an ultramafic contact that is buried under overburden. Channel samples from 2003 returned values up to 4.40 g/t Au over 0.5 m. Visible gold occurs in several veins and grab samples have yielded up to 22.72 g/t gold. Brecciated Felsic volcanic rocks tend to be anomalous in gold (>100 ppb Au) and can contain up to 5% pyrite. The showing area is approximately 35 m x 30 m in size. Mineralization encountered in a single drill hole consisted of strongly altered (quartz-sericite and pyrite) felsic volcanics with up to 5% chalcopyrite locally. Several anomalous gold values were returned (>100 ppb) with copper values up to 0.2% in chalcopyrite stringer mineralization (Assessment report 20000000647).
