These are ideal rocks around which to look for gold. Indeed, the gold is transported from the lode by natural powers such as wind and rain. During this process, there is a chance that it will remain trapped in between crevices and cuts. Ultimately, cracks in rock formations are the best locations to locate fine gold particles.
