Aug 10, 2009 (A Wilson) - The quartz vein is hosted by steep-sided ridges of Nipissing diabase. The vein is exposed as blasted rubble along the base of the east of a diabase ridge and as a lens which pinches out to the west exposed in the outcrop. The vein has a maximum width of 15 to 25 m along the base and pinches out and disappears about 15 m up along the face of the ridge.

Aug 10, 2009 (A Wilson) - The quartz is massive, medium-grained, translucent and glassy grey to milky white. Fracture controlled smears of iron staining and sericite and chlorite are noted in the quartz vein. Three samples collected from this site by the OGS returned a normalized SiO2 value of 96.91%. The quartz body is quite small and highly contaminated with xenoliths of diabase.
