How To
Montana’s Rosetta Stone: Discovering Mines In The Treasure State
May 2015 by Don Madore
This is the intelligent way to start modern prospecting. The value of literary research yields challenging outings, specimens, history and geologic research.
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.
So You Want To Be A Full-Time Prospector?
The high price of gold and the poor economic conditions here in the US have created an unusual situation—a large number of folks are thinking seriously about getting into prospecting and digging for gold on a full-time basis.
Breaking Boulders With Explosives
The process we will be using is called “blockholing,” and it is commonly used at mines and in construction projects to break up oversize material into sizes that can be easily handled.
All About Trommels and Screens for Placer Gold Recovery
The right speed accumulates only the heavy materials and allows all of the lighter stuff to flow through. This optimum speed is dependent on the size of the gravel you need to move through the system.
Evolution Of A Desert Wash Plant
The water instantly dropped though the screen, leaving a pile of mud behind! I was so excited that I replaced it with a 150-mesh screen, and the same thing happened!
Proper Assaying of Placer Samples
The whole purpose of sampling mineralized ground is to measure the values in a small volume of material that would be representative of a much larger volume of similar material. The key word is representative. Chemical and fire assaying will not accurately represent placer deposits by themselves.

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?
