A Short History of Hydraulic Mining in California
December 2021 by Josh Reinke
To add to the confusion, the dam wasn’t holding back a large amount of water. It was full of gravels and had a small creek running through it. I had to know more.
Most of the commercial mineral deposits are on the south and southwest part of the range between Minersville and Milford, though small amounts of gold and silver have also been found in iron-rich outcrops in the basalt to the south of Milford.
I frequently get asked, "What should I look for when I am out prospecting that will tell me there are good amounts of gold present in the ground?"
The gold in this area can get quite large. Most of the pieces are about half a pennyweight on average.
As a guide to those who are thinking of taking up this activity or those who currently practice this trade, I have created a listing of the primary tools and equipment I use when nugget hunting.
On our fourth trip, we finally reached the top edge of the old hydraulic pit, and it was monstrous.
I made my way up past where I left off and the wash was going to end in about 100 feet. It was then I got a sweet signal.
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.
