All About Quartz—Part I
May 2013 by Chris RalphOne of the first minerals most prospectors learn to recognize is quartz, because, in the right circumstances, it can be an excellent indicator mineral for prospectors. Quartz is common, easy to identify, and is often associated with gold and other valuable metal deposits.
The same questions you ask yourself about gold trapping features in the present stream can be applied to the benches above the stream. Just imagine the stream at a much earlier time, before it cut its way down to the present level…
The very first thing to find out...is if the detector has the ability to be ground balanced.
As I write this, I am still on a rush from taking my 9-year-old son, Jeffrey, prospecting for the first time this past weekend. It’s not that he hasn’t been along on numerous outings before: this is the first time that just the two of us went out for a day of drywashing and detecting under the desert sun.
Back at the entry point of the mine, we took turns slowly crawling down the slope leading into the mine portal with our metal detectors, hard hats and flashlights. The mine was hand dug and is about 75 yards long.
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.
It is important to note that discrimination is a type of electronic filtering. The signal is analyzed, and depending on the discrimination setting, identified as either a target to be dug or a target to be ignored.
Because the old timers were so good at locating the better paying deposits—most of them along clay seams in this particular area—it makes good sense to try and locate these clay lines at old mining sites.
