Indicator Minerals for Gold & Silver
April 2011 by Chris RalphIn this article, we’re going to take a look at the minerals that contain gold and silver, and how you as a prospector can identify them in the field.
I get a lot of questions from prospectors about garnets, their value and what they tell us about the geology of some types of mineral deposits. So I thought it would be a good idea to take a closer look at the lowly garnet and learn a bit more about it.
A treasure-seeking young man whose name will forever remain anonymous made the months-long journey either over land or by sailing ship to California after word spread about the gold strike in 1849.
Chances are better that both types of gold did not come from the same source. Let's look at the probable conditions to cause two types of gold in a placer.
We have to remember that the earliest miners were not geologists, but came from a variety of backgrounds. Their survival depended on finding enough gold so they worked hard and adapted to whatever challenges these new areas presented.
Until just recently, platinum-group metals (PGMs), especially palladium, had been holding their own on the market. But, Russia has now resumed shipments and it has brought prices down.
One of the most important things prospectors do is work to figure out where to go prospecting. Along with understanding the basic geology and putting yourself in a favorable area, one of the things a prospector might consider in finding a location to search is the existence of mining belts also known as mineral deposit trends.
I set up my dry washer on the north side of the cut and sampled the bed rock and dumps around me. As I was only sampling, I ran for 20-30 minutes, shoveling from a variety of areas.
