VLF Detector Operating Modes
December 2015 by Steve Herschbach
Back at the entry point of the mine, we took turns slowly crawling down the slope leading into the mine portal with our metal detectors, hard hats and flashlights. The mine was hand dug and is about 75 yards long.
On the day prior to Mother’s Day I was able to get out and spend a few hours prospecting. I wanted to try some new settings on my detector, and I had a place in mind to do that.
...I got the faintest of rises in the threshold. It was hardly a signal at all, and I thought it was one of the many, deep, hot rocks in the area.
So why would a modern-day prospector want to learn about a method of mining that was banned by the courts more than a century ago?
We had been picking away at it, but the going was mightly slow. Why not use some explosives to advance a little quicker?
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.
