I think its 0.35% or 30 ppm. Azurite & Malachite are the lower grade copper. Bornit, Chalcopyrite, Calcite etc are the high forms of Copper. 0.35% in my view is not exciting. The the Battery out of Kilkivin rock specimens are scattered everywhere like this where th old mine was years back. I think tonnage at 4% is what wold excite me. Just my opion of course.
