Dec 07, 2005 (P Beach) - Chalcopyrite and pyrite occur as disseminations and as narrow lenticular bands in altered Bruce Limestone. Sulphide bands are commonly parallel to bedding in the limestone. Better grade copper mineralization tends to occur in chlorite rich portions of limestone, where sulphides are often relatively coarse grained and bedding of the limestone is obscurred. Minor quartz chalcopyrite pyrite veins cut across the bedding of the limestone. The limestone strikes N, dips 10-20W and is underlain by a Nipissing diabase sill. The deposit has been drilled over an area of 900 by 650 feet. The copper mineralization is mainly concentrated in 2 layers; an upper, very low grade zone about 4 feet thick, and a lower, higher grade zone 6 to 7 feet thick. The best section assayed 1.94% Cu over 7.0 feet, the remainder averaged 0.25% to 0.75% Cu across thicknesses of 2 to 5 feet. (ODM 1969 MRC 12 P 43).
