Epithermal Gold and Silver Deposits
April 2017 by Chris Ralph
Epithermal deposits form in the ground at shallow depths. They are popular with prospectors because can yield very rich deposits and they are widespread in the Western US.

The Basics of Geophysical Exploration
February 2012
In developing a mineral property or mining claims, one of the first goals is to identify and quantify valuable deposits. The classic method of doing this is by drilling holes into the ground to sample what is below the surface. The problem is that one or two holes usually are not going to tell you a whole lot...

Yesterday's Gold—Today's Mine
December 2011
It would seem that we are often indeed destined to repeat history. In terms of gold discovery, even with all the advancements that have been made over the years, it seems we are once again on the cusp of returning to the 1800s world of gold mining. Even as you read this, a new gold rush is taking place in a sleepy little town in South Carolina.

A Journey Into the Silver Peak Range
June 2013
The Gold Rush in California called hundreds of thousands of souls to leave their homes to journey to the the far reaches of the West. At first the rich goldfields of the Sierra Nevada beckoned to these adventurous pioneers.

Prospecting for Diamonds in Kimberlite
January 2014
Kimberlite is very difficult for geologists to find, let alone prospectors and rock hounds. This is because kimberlite is rarely exposed on the surface and few people know how to identify the rock.

Eolian Placer Gold
February 2012
I would first like to mention that I am not a geologist. I have, however, spent the last 8 years intently searching for gold nuggets with a metal detector. I have found gold in numerous locations, and in several different types of gold deposits.

Calcite and Limestone
February 2017
The other distinguishing feature of calcite has to do with its chemistry. Geologists sometimes take a small bottle of dilute hydrochloric acid out into the field with them because calcite reacts with acids to make a bubbly foam.
