[QUOTE="user 4386, post: 590518, member: 4386"] Simple answer is - stick with the stuff we prospect now. The grade is extremely low (totally uneconomic) and the grain size of the gold so fine that it can float on the surface of water due to surface tension of the water, so does not concentrate and cannot be concentrated by water-gravity methods even where more abundant (e.g. river muds in Oregon_Washington such as Columbia River). The exceptions are well known (eg Nome, Alaska beach deposits), mostly small, and well explored (including offshore in Victoria such as the Burdekin delta, Corner Inlet). You require movement of water to concentrate gold, so it dumps out when it hits a sea or lake. Usually the river is slowing well before it reaches most lakes, so has dumped its economic gold.
