[QUOTE="echidnadigger, post: 14097, member: 719"] I also have a question about this fine gold. I was once told that a machine will not see gold that is finer than what the detector is normally capable of detecting if it is spread around even though there may be lots of it. The detector must apparently have it in a size big enough to be detectable as lets say a lump or thin sheet like foil. So my question is, how does a detector see small gold that is not visible and is spread throughout a target rock, as in this case. Or was there some larger areas of gold even though it may be thin in this specimen that made it detectable. Maybe it was because it was mostly connected in some way even though very fine, it may have collected enough of a field to have given a signal. I remember one piece of gold that was sun baking and was about 1 gram in weight but gave little to no signal even when out of the ground and slid back and forth across the coil. It was very reefy with no solid structure at all. I would love to know a bit more about this phenomenon and how this big one may have come in as a target on a machine. [/QUOTE]
