How Deep Can That Detector Go?
April 2021 by Chris Ralph
Knowing how to get the greatest depth performance out of your detector can be a handy thing, but it’s not an easy, simple matter.
Some ask if a prospector can collect an entire ounce in a day. It is possible; I’ve done it before.
Bela and Barbara Kovacs began prospecting for gold about seven years ago as a family orientated outdoors activity. A welder by trade and lured by the simple fact that beach sands can contain small bits of precious metals, Bela decided a few years ago to build a sand sucking contraption that can sift the shoreline for anything worth keeping.
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.
Our theory was that a dredge would collect far more material in a shorter period of time, leaving us with ounces of gold every day.
Palladium may well be an underexplored element and therefore an opportunity for prospectors and geologists. This is because they are often less than obvious and other than the native metals, a chemical analysis of samples is required to identify PGM-enriched rocks.
I suspect detailed geological mapping and prospecting would lead to discovery of one or more overlooked gold deposits in the district even though it has been heavily prospected in the past.
If the material drops down out of the hopper too fast, it can overwhelm the riffles and you can blow the gold right out. If it runs too slowly, the riffles can clog up and the process is too slow.
