Sampling, Hydro-Shocking & Cleaning Quartz-Gold Specimens
May 2017 by Reese Townes
Many specimens have a small amount of gold and are not pretty to look at. There is a nifty way to give them a makeover and make them much prettier than they were when you found them.
A Wilfley table works best when all of the mineral being run across it (the pulp) is about the same size. For this reason, I took a good look at each of the samples.
The University of Nevada, Reno Mackay School of Earth Sciences and Engineering, Department of Mining Engineering has begun offering online courses for miners.
The most commonly asked question in metal detecting is, “Which metal detector should I get?” People worry a lot about not getting the right machine. They do not want to waste their money and their time with the wrong metal detector.
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.
There are not a lot of tools needed to get out and take advantage of the situation. Other than my wetsuit, I typically travel light with a gold pan, maybe a pry bar and a few crevice cleaning tools.
