Gold Detecting Strategies for Hydraulic Mines and Debris Flows
December 2017 by Reese Townes
The old timers typically washed these areas down to bedrock, and some areas appear terraced. I would imagine this is because these hydraulic mines were generally where the miners found old Tertiary river channels on the sides of mountains that were gold-bearing.
If the material drops down out of the hopper too fast, it can overwhelm the riffles and you can blow the gold right out. If it runs too slowly, the riffles can clog up and the process is too slow.
Once you have determined that the land is locatable, the next step in the claim research process is to determine if the land has already been claimed by a previous locator.
From this I inferred that engine 2 had a carburetor problem. In this article, I discuss the specific engine/carburetor problem, and the surprising solution to this problem.
I had been busy representing the Prospecting and Mining Journal this spring, but prospecting season finally arrived and I’ve been out digging for nuggets—I’ve even found a few. I know a number of prospectors who are armed with new metal detectors and headed to the hills to look for that precious yellow stuff.
There is a surprising amount of detectable gold under the water’s surface. The right tools make it much easier to find, and with a little patience and practice you can take advantage of this underappreciated bonanza.
Dredges actually do pretty well in freezing conditions. There are a few tips you should know, however.
These are entry-level machines designed with gold prospecting in mind and with the ability to handle mineralized ground and see nuggets of a grain or so in size, perhaps smaller.
