The dump consists of the concentrator tailing discharge, over a period extending to the present date. According to daily samples taken during that period, the copper content is about 0.64 per cent, and the silver 0.48 oz. per ton. The peak of the dump, or the point where the tailing is discharged, carries about 0.75 per cent, copper, while down toward the toe, and where present excavation is taking place, the...
