Detecting Old Pocket Diggings
February 2013 by Ray MillsLooking around, I could tell that this was an old hand-digging. As I walked around the perimeter of the digging I could see shovel and pick marks scratched on the clean, hard clay and bedrock.
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.
Day three was a copy of day two. I started real low in the long wash to see if I could prove how far down the gold had made it.
The operation and techniques employed are highly successful in producing free gold with minimal work involved while maintaining an environment protection process through the use of recycled water and a settling pond.
Since this position was the least desirable due to the hard physical labor, the bucking room was used as punishment. Do you have a mediocre worker? Bad attitude? Off to the bucking room!
Once indicators start showing up along or below a contact I start to get excited. When I have shale, and outcroppings of diorite with iron-red, gritty soil and some clay thrown in, I really get lightheaded. I may be a mile away from the nearest diggings but that’s okay. I just found a spot that could provide some nice nugget hunting.
Federal and state regulatory agencies often cite mercury and methyl mercury in our waterways as a major factor for further restrictions on placer mining, and on suction gold dredge mining, in particular. However, these regulatory agencies are minimizing selenium and its neutralizing effects.
When I teach people about finding gold, I often explain that it is helpful to think of any river or stream that carries gold as being something like a sluice box.
