Metal-Mineral Identification Utilizing a Detector
November 2005 by Jim StraightSeldom is a metal detector used for ore sampling today. Nevertheless, this procedure still works as all BFO and VLF detectors have a non-conductive mineral zone and a conductive metal zone with a neutral null zone between them.
In the northwest section of the Kingman Quadrangle, the Kingston Range rises out of the alluvium of the Pahrump and Mesquite valleys. Kingston Peak, rising to an altitude of 7,320 feet, towers high above its foothills.

Across and downstream of our operation was a large pile of huge boulders. It was logical to think that water forces may have deposited gold in and around these boulders. We moved our dredge over and started pulling the rock pile apart.
There is a surprising amount of detectable gold under the water’s surface. The right tools make it much easier to find, and with a little patience and practice you can take advantage of this underappreciated bonanza.
There are situations where small-scale miners cannot use dredges or high bankers. This is when it’s time to join the ranks of the old timers and their use of hand methods. Back when a gold pan, pick and shovel and sluice or rocker box were the...
Every machine has its own adjustments and settings, but one of the most important ways to increase the capabilities of whatever detector you own is through the use of accessory coils.
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.
