May 28, 2020 (Therese Pettigrew) - Coleman (1896) examined a "large mass of quartz at the contact of an eruptive mass of granite with greenish grey schist". He noted that the quartz is "not a fissure vein" and that it dips 80 degrees to the northwest with granodiorite forming the hanging wall. "Black schist, a little pyrite and dolomite" were reported to be present in the quartz. Teeshin Resources collected sample 14368 in 1987. It returned 1.71 ppm Au, 7.7 ppm Ag, 202 ppm Pb, and 43 ppm Mo (Assessment report 52E10NW9469).
