Nearly all placer gold, both coarse and fine, originates from the erosion of primary hard rock gold deposits. Some placers are re-concentrated from older placers, but at least some time in the past, these came from primary deposits. A small amount of coarse gold has probably resulted from secondary enrichment processes, but the majority grew as
