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.
How many more clays seams lie adjacent to known shear zones and quartz veins in the pocket areas of southwestern Oregon?
I figure there are a lot of new people out there who have the same question. I will try to give some answers that hopefully will give you more confidence in finding your own spots.
The old report I read indicated all they ever did was dig some trenches and take samples. It sounded to me like a good place to take my metal detector...
I have seen many samples taken originally with an eye toward getting the highest grades possible, but later someone claims that those results represent an average grade of the whole gravel deposit.
They… create negligible fumes and much less fly rock than blasting. Below are some tips on maximizing your effectiveness with these tools.
Doug told me that there had been a 100-year flood that took place in October of 2013 and it washed out part of the mile-long landing strip. It also washed a large, wide gully down below and above the camp.
There is a material processing principle widely used in large milling operations to improve recovery that is poorly understood by most of the micro-mining and prospecting community...
