Following Clues to an Old Mill and Vein Strike
August 2012 by Don RobinsonMy last update on this adventure was in the April 2012 issue and involved our search for the northern extension of the Cedarberg Mine. At that time we had found it and we were in the process of returning for some detecting when Mother Nature struck with a late rain and snow storm.
I started with, "Hey, Rusty, tell me about the time..." and that was all it took.
...day one was like watching the Gold Rush television show. He furiously worked the nozzle in an up and down fashion that resembled Jack Hoffman sitting on a backhoe.
Can a metal detector be used to find limonitic gossan material?
"Suh-wheet!" I exclaimed as I sprang to my feet and quickly pumped my detector coil high overhead to alert Smokey that I had just found a nugget.
It was time to prime the pump and start the engine! Dan’s priming method is to use a small, submersible, 12-volt pump. My priming method is to use a hand-operated diaphragm pump.
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.
I probably swung over a few targets without noticing them. My first target came about ten minutes later as I went over a part of the high bench in this wide section of the dry wash.
