The Silver, Gold and Gemstones of Candelaria, Nevada
February 2015 by Chris Ralph
The Candelaria area is of interest to prospectors not just for silver, gold and other metals, but also for the beautiful gemstones found there.
Gold From Cemented Gravels

The Basics of Geophysical Exploration
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...
All About Chalcopyrite

Know Your District
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.
Understanding Large Gold Deposit Types: Discovering New Mines
The other opportunity that I see is in seeking unusual types of deposits. Specifically, the prospector would be searching for the stuff no one (or almost no one) is searching for. These deposits are effectively hiding in plain view.
A New Look at Old Mines
Exploration companies are actively looking for properties with profitable potential, even if the ground was once cast off as too low in grade to be economically viable. This is especially true in states that are reasonably friendly toward...
