Follow the Line

Four nuggets, ranging from one to four pennyweight, had been found originally. All four nuggets were found in a line about ten feet apart from each other.
The first pieces found were in a spot that most gold hunters would not even detect, right in the middle of a downslope meadow.
Over the years, I've noticed a pattern in the type of rocks associated with the best gold deposits in Midwestern glacial gravel.
...I decided to excavate the semi-frozen high-bank that was resting on a soft shale bedrock footing. Within three feet, I encountered an intrusive!
I began detecting at the bottom of the gully and started making my way upstream. About mid-way there was a nice, flat stretch for about ten feet.
I like to think in terms of “conductive mass” because it is a combination of both the conductivity of the metal and the size of the target that determine how a detector sees conductivity.
Once a seam is found it can be traced for miles in either direction. While you are tracing a clay line, you are looking for indicators. The indicators that I look for are ironstone, hematite, different color clays intermingled with the clay line, and a very iron-rich, brown gritty soil.
