Using Vegetation and Soil Conditions as Prospecting Aids
January 2013 by Jim HalloranWouldn’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.
Easing around the bedrock ledges and rock hopping, Terry and I came out into the open and were looking at a nice run of bedrock.
Lots of prospectors are trying out nugget detecting for the first time and finding out that it isn’t all that easy. In fact, in my opinion, metal detecting for nuggets is perhaps the most difficult form of prospecting that one can take on.
Some of the items that I’m going to go over are outcroppings, ditches, exploratory trenches and contacts/surface materials. I am going to speak about each of the above items in as much detail as I can, and then towards the end of this article I will tie them together.
...I decided to excavate the semi-frozen high-bank that was resting on a soft shale bedrock footing. Within three feet, I encountered an intrusive!
“Much of the ground where Ms. Hollingshead found her diamond is made of unweathered volcanic rock. When it rains, flowing runoff often leaves loose gravel, and sometimes diamonds, on the surface in these areas.”
I knew the nuggets got into the nugget patch somehow, I just had to figure out how and from what direction they came.
The holes were overloaded with explosives, but I didn’t know it. I was just a green mining engineer fresh out of school and told to watch as the experienced miners set the charge.
