Free gold is the portion that is easily removed without the use of complex chemical procedures. Miners have been extracting free gold from hard rock sources for thousands of years. It simply requires that the ore be crushed and broken apart enough that the gold can be separated from the host material.
As always research and exploration are essential yet time consuming. We look at all the modern rivers and streams hydraulic pits buried river channels exposed drift tunnels old dredging fields and hard rock vein systems too. We read all the books about past mining that we can looking for clues and alternative locations.
