Gold Geochemistry: Where Does Gold Come From?
February 2021 by Chris Ralph
Prospectors often wonder why gold deposits in veins like it does. Why is one vein rich while another is barren, even though they are only a few hundred feet apart?
I like to think in terms of “conductive mass” because it is a combination of both the conductivity of the metal and the size of the target that determine how a detector sees conductivity.
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.
...we were able to pull out close to another 3+ ounces of small, angular Silver City gold. This also included several more small nuggets, pieces of wire gold and some quartz-gold pieces—not bad for 4 days with a small sluice.
Some creeks have nuggets, while others, particulary the rivers, nothing but fine gold.
After a short time, the tailings pile can get very large, and can actually block the downstream end of the sluice box.
We had been picking away at it, but the going was mightly slow. Why not use some explosives to advance a little quicker?
What I saw was a beach area that was just completely covered in black sand. Rubbing my hands close together like a kid in a candy store, I could not wait to get set up.
