[QUOTE="BrokeInBendigo, post: 603756, member: 18943"] It seems that today, researching where gold occurred in the past is far less a useful endeavor than in it was yesteryear. I mean, for significant finds. There will always (?) be little bits in a given area, but untouched and accessible ground is rare. More useful is to understand the geology of gold and follow that. I'll define "detectable": A nugget that... 1) my detector can see and 2) is of a size and depth that puts it in the green zone of this graph: [img]https://www.prospectingaustralia.com/forum/img/member-images/18943/1618134926_nuggget_to_hole.jpg[/img] If a nugget is too small, I'm only willing to put in a certain amount of energy into digging the hole and, very importantly, isolating it from the dug-out soil. There are more variables to this, such as ground hardness, how broke I am, if it is raining or not, how badly I have to pee, how many pieces of junk and I've dug in the recent past, etc. But this graph conveys the general idea.
