Geological Age: Early Precambrian
Dec 07, 2005 (P Beach) - A quartz carbonate vein occurs in a shear zone along a granite - diabase dike contact, that strikes, on average, N80W and dips 65N. The vein has been traced for about 4000 feet on strike, and ranges in width from about 1 foot to 9 feet. Chalcopyrite, pyrite and minor galena occur in the vein. Three main showings on the vein. The westernmost, 'A' showing is located 900 feet W of No. 1 shaft. A bulk sample, 500 lbs., from a width of 9 feet., assayed 9.84% Cu; 0.085 oz./ton Au; 0.445 oz/ton Ag. The vein is 6 feet wide at 'B' showing, (at No. 1 shaft); and the dump at the shaft is estimated to average 4% Cu (ODM 1957). The vein maintained an average width of 6 to 7 feet to 60-foot depth in the shaft, thereafter it was replaced by narrow quartz stringers. 'C' showing, located 1200 feet E of No. 1 shaft exposes a vein for a length of 60 feet, and ranges in width from 10 inches to 2 feet. A chip sample over 28 inches assayed nil Au; 0.63% Cu.
