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.
Gold is a fairly widespread mineral in the Italian Alps and in the Northern Apennines. It is found both in primary mineralization and in past and recent floods.
As he was working near the extreme low end of the ground sluicing, I heard a yell through my headphones. Making my way down to him I could see the smile from a long distance.
...day one was like watching the Gold Rush television show. He furiously worked the nozzle in an up and down fashion that resembled Jack Hoffman sitting on a backhoe.
Across and downstream of our operation was a large pile of huge boulders. It was logical to think that water forces may have deposited gold in and around these boulders. We moved our dredge over and started pulling the rock pile apart.
In some ways, silver is the forgotten precious metal because it straddles both the world of precious metals and jewelry, while having many important industrial applications like a base metal. The price of silver reflects both the precious metal investment demand as well as the industrial demand.
The operation and techniques employed are highly successful in producing free gold with minimal work involved while maintaining an environment protection process through the use of recycled water and a settling pond.
The holes were overloaded with explosives, but I didn’t know it. I was just a green mining engineer fresh out of school and told to watch as the experienced miners set the charge.
