Tips for Detecting Old Hydraulic Pits
October 2012 by Ray MillsThere are several counties around Shasta County that offer very good gold detecting. Many of these locations are old hydraulic pits. While detecting these old pits over the years I have come up with some ideas on how to go about hunting them.
Q: Will my detector react to fine gold?
Our research indicated this whole area had been claimed by Newmont mining company for several years, but when the price of gold dropped they let the claims expire, and we confirmed this with the local BLM office.
One 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.
Because these crevices catch and hold gold so well, it's worthwhile to learn how they form, which ones are good for catching gold and which ones are not.
It’s worthwhile for the prospector using a metal detector to know a little bit more about the association of iron and gold as well as how iron minerals affect your metal detector.
The first location we worked was a small, dry ravine cutting through many mineralized zones in an area where some hard rock mining had taken place in the past.
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.
