Placer Gold Deposits of New Mexico
February 2019 by Chris Ralph
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.
The most commonly asked question in metal detecting is, “Which metal detector should I get?” People worry a lot about not getting the right machine. They do not want to waste their money and their time with the wrong metal detector.
Chances are better that both types of gold did not come from the same source. Let's look at the probable conditions to cause two types of gold in a placer.
At first, I tried to shift things around, but then a hand with a rock would appear, so I would stop trying to adjust my gear and grab the rock to keep things moving.
When everything is still dry, one of my favorite methods of prospecting is using a straw to blow out small cracks and crevices that dot the exposed bedrock along a stream.
I love to see old-timer workings while I am out detecting for gold. For one thing, it assures me that gold came from there. Second, it tells me gold should almost certainly still be there.
Within this area, about two million ounces of gold and fifty million ounces of silver have been mined. Faults, dikes, veins and fissures that carry the ore form a concentric radial pattern—like spokes on a wagon wheel—around the caldera core.
Looking for nugget laden bedrock in forested mountain regions, you first need to explore the banks of the gold-bearing streams and look for the bedrock that is exposed as this is your starting point.
