Prospecting & Detecting
Mining Pegmatite Deposits
July 2018 by Chris Ralph
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.
Detecting Canyon Bedrock in The Sierras
My plan was to go up the canyon along a ridge and then drop into the canyon whenever I came across a spot that might give me reasonable access.
Old Mine Sites and New Technology
We’ve had two trips to the deserts of Nevada and explored mines and mill sites, hiked miles of ravines in California, and swung our detector coils over thousands of square yards of bedrock.
Prospecting Underground: Use Caution
In underground placer work, the contact point of the bedrock tunnel and the gravel is a very weak point and always has to be timbered. The bedrock here is thin, fractured, and the gravels loose from many years of oxidizing.
Old Patch, New Detector
I have been detecting the area on and off since I discovered it. Every time I bought a new detector it was the first place I went to.
Deep Nuggets From The Strange Little Patch
I began detecting at the bottom of the gully and started making my way upstream. About mid-way there was a nice, flat stretch for about ten feet.
Detector Prospecting Accessories
One of the first things to consider but that many people ignore is ergonomics. Prospecting for gold can involve long hours, often for days or weeks on end.Are There Any Good Prospects Left?
This type of thinking will get you discouraged pretty fast, and soon all of your mining equipment will be found gathering dust in your garage.
