Prospecting & Detecting
Using Vegetation and Soil Conditions as Prospecting Aids
January 2013 by Jim Halloran
Wouldn’t it be great if you could know if there is gold in the ground without setting foot on the ground? Well you can, to a certain extent, if you can recognize mined ground from unmined.The Essentials of Dry Washing
