Apr 10, 2019 (Therese Pettigrew) - Chalcopyrite occurs as patches and disseminated grains in concordant quartz-carbonate veins which are enclosed by foliated mafic volcanic rocks. Individual veins are up to 16 inches (40.6 cm) thick, but lateral continuity is difficult to establish. They are assumed to strike at about N50E, as do the enclosing rocks. As much as 20% of individual veins consist of chalcopyrite. Grab samples collected by OGS staff returned the following results: Sample EF 2-18: 0.42% Cu, 0.01 oz/t Au, 0.23 oz/t Ag; Sample EF 2-16: 3.35% Cu, 0.01 oz/t Au, 0.33 oz/t Ag (Thurston and Carter, 1973). Sampling by Esso Minerals in 1981 returned values up to 0.41 oz/t Au, 0.92 oz/t Ag, and 2.2% Cu (Assessment file 52I10SW0001). A sample collected in 1996 returned 3888 ppm Cu (Assessment file 52I10SW0038).
