How to Stake Your Own Claim—Researching Mining Claims
Once you have determined that the land is locatable, the next step in the claim research process is to determine if the land has already been claimed by a previous locator.

Revisiting The Old Mini Patch
Today, the greatest gold rushes occur due to technological advances capable of discovering gold where it once was extremely unlikely or difficult.
Pros and Cons of Big Detector Coils
