Prospecting & Detecting
Tips for Cleaning Gold Nuggets
June 2019 by Ron Kliewer
I pulled out the nuggets I had worked on previously and looked at the size of the wire basket that the items to be cleaned are placed into. It looks much like a miniature french fry deep fryer.
The Value of Evidence
That prospecting effort you are about to spend your time on...is it worth your effort? If you are going to devote your time to it, you will need all the facts you can get.
Pickers and Nuggets
Mike and I each selected a side of the creek and started to work our way upstream. We both worked the water and sides of the creek, and better than half the gold found in this area is in the water.
Excavator Testing Wet Placer Ground
The excavator or backhoe has become the tool of choice for testing placer ground. These machines are the best way to explore and sample a placer deposit if the ground is not too wet or frozen and bedrock is not beyond the reach of the machine.
Gold in Quartz
Because quartz and gold may be deposited together across a considerable range of temperatures, not all quartz veins are the same, and there are several different types of gold-quartz deposits.
VLF Detector Operating Modes
It is important to note that discrimination is a type of electronic filtering. The signal is analyzed, and depending on the discrimination setting, identified as either a target to be dug or a target to be ignored.
How to Beat the Heat--and The Bedrock
The pit was a classic one—exposed shale bedrock with all the material being washed out one end of the pit. Within a few minutes I had a nice mellow signal that was in open ground.
Route Planning Using GPS
My intention was to end this discussion with waypoints and routes, then I found USGS maps of the Plainfield Quadrangle.
