Mineralization consisting of chalcopyrite, bornite and calcite which occurs as patches and as fillings of fractures in the andesitic and basaltic rocks of the Harbour Main Group. The occurrence consists of an old working with a 90 foot (27 m) shaft. Malachite stains are abundant on the surface of the host rock. Copper Mineralization also occurs in the subaerial mafic volcanic rocks as occurrences which usually contain one or more of native copper, chalcocite, chalcopyrite, covellite and bornite in veins, amygdule fillings, disseminations and shear zones. This deposit was documented as early as 1868, and other than the 27m shaft this deposit has never been drilled off leaving much unknown about the source and amount of contained copper and silver within this deposit. Assays from the surrounding host rock yielded results as high as 23.60% Copper and 236.30 g/t silver.
