Finding Gold with a VLF Detector—Part III
June 2014 by Steve HerschbachThe higher the sensitivity setting, the louder and sharper the signal from a gold nugget or other metal target.
With successively lower temperatures as the water mixture cools, new sets of minerals are formed and many of those stable at a higher degree of heat became subject to alteration as the temperature progressively moved lower.
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 was one of those awkward situations as we walked, fatigued and too thirsty to speak a word.
Old mine workings and tailing piles can represent opportunities on many levels, from the chance to simply find a nugget on up to the commercial reworking of the old tailings for profit.
In the “toolbox” of most every prospector there are certain tools that we tend to use consistently for a variety of reasons. Have you ever noticed that tools and equipment tend to wear out, rust and fall apart whether we use them or not?
For the last two years we’ve held a hands-on prospectors training session in the Iowa Hill district of California’s Mother Lode country as a part of our Gold Prospecting and Mining Summit event. Because of this, I thought it might be good to take a look at the history, geology and opportunities that the Iowa Hill district still offers to the individual prospector.
Normally the detector he was using would sound off with a definitive high-to-low tone when passed over a piece of gold, which distinguished the gold from the many high iron content "hot rocks," but this one was different...
