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.
During my adventures I’ve learned a few key best practices that help me to consistently find gold nuggets with my detectors. You can apply many of these best practices to any type of prospecting. These best practices are really common sense; however, they are easy to neglect.
…it was immediately evident the previous owner had not been using a detector. During just a few months of working the dumps part-time, he recovered gold in quartz specimens valued in excess of $40,000.
After he excavates the ore down to bedrock, he goes over the bedrock with a metal detector to ensure he didn't leave any gold behind before he backfills the area.
I will have to admit, I actually was brought to tears just thinking about what I had just done. I knew the gold was there, but I never thought I would be so fortunate to find such a prize nugget.
Ground sluicing, surfacing and scratching are a few names given to the recovery of gold in shallow areas. Where I live, the hills are dotted with small surface diggings.
I have always enjoyed finding things. As a kid and up through college I searched for arrowheads, rocks and fossils. One day I saw an ad for a metal detector in a magazine, and a week later I was digging up everyone’s yard...
I was amazed and surprised, and I took a moment to admire how beautiful this coarse chunk of gold was. It later weighed exactly one-half ounce.
