Ask The Experts: How do I identify gold in hard rock that may be mixed with other metals?
September 2016 by Chris Ralph
Q: Aside from the softness scratch test and other methods of identification, what feedback would you have on identifying gold in hard rock that may be mixed with other metals that affect its color?
The first step in my recovery process after milling the ore to the desired size is to table it. On this particular ore, I get good results milling it to minus 100 mesh.
I researched the Internet and found a number of table makers, but technology has changed in the last 25 years. No one could sell me a kit for a new deck with wooden riffles...
Q: Can you offer any information on proper mining claim procedures?
Looking at the exceptions to the basic rules is sort of an advanced prospecting discussion, but the readers of ICMJs Prospecting and Mining Journal are plenty able to handle it.
The next morning, I retrieved the compressor and again attacked the sticky head bolt. As if by magic (and some applied physics) the head bolt sighed and finally broke loose.
It is this ability to hear and respond to the faintest of audio signals that I believe separates the best nugget hunters from everyone else.
