All About Quartz—Part II
July 2013 by Chris Ralph
In our May 2013 issue, we took a look at the mineral quartz, a mineral very commonly associated with gold. However, gold is not the only reason prospectors are interested in quartz. Quartz can also be very valuable as a gemstone

Prospecting Tales: Forest Service, Fires and Bears—Oh My!
October 2013
I woke up on Sunday morning, August 10, to heavy smoke. I saw where it was coming from, but it seemed like it was a long way off so I thought I was okay for the time being.

Proper Assaying of Placer Samples
November 2012
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.

Time Well Spent
January 2012

Excavator Testing Wet Placer Ground
April 2013
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.

A Good Start
July 2011
We split up in order to cover a larger area and found good color almost everywhere. The bedrock was shallow on both sides of the river, but the inside bend was where we concentrated our prospecting.
