A single piece of gold ore generally has very little actual gold content. Although a very rich ore may have some visible gold present, the vast majority do not actually have any visible gold present, and only crushing and processing of the ore will release the gold within to host material. For example, lets say that a mine was processing ore valued at 1 troy ounce of gold per ton.
