Prospecting & Detecting

November 2016 by Ray Mills
The names attached to these areas came about from many sources. Many are easy to see why the name was given while others had a more contrasting note to them.
Placer Gold Deposits of New Mexico
While a large number of locations have yielded some placer gold, most of the state’s placer production has come from a few productive districts.
Dredging Backwards?
Before I tell you what dredging backwards is, I’ll tell you why my team and I decided to give this very unconventional dredging method a try.

Piles of Gold
These gritty clay lines were only a quarter of an inch up to three inches wide. Once the line had been laid out, they would look at the wall of gritty clay material and seek more indicators.
Metal Detecting Old Hard Rock Mine Dumps
The type of mine dump that is best for metal detecting are the ones that consist of mixed sizes of rock and are located near some sort of excavation, commonly a shaft or adit. Sometimes the piles located along a trench dug by the miners can be productive as well.

My very first pan full of gravel showed several nice small flakes that were just big enough to be picked up with my fingers.
