Conductive Minerals and Your Metal Detector
August 2014 by Chris Ralph...most prospectors don't even think about the conductivity of minerals, but there are some that do conduct electricity to a certain degree, so metal detectors will respond to them.
I am going to suggest dozens of ways you can increase suction power, dredge to greater depths, and improve recovery methods in your sluice box.
After paying for the mine fleet, mill capital, supplies, fuel, power and labor, at today’s metal prices, does this mine make a profit?
There are currently three controlling agencies or entities over suction dredging in California—and you can make that four if the state legislature decides to further muddy the waters with additional legislation to block suction gold dredging in the state.
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 have been finding nuggets all my life, beginning in Sierra County 50 years ago, and believe me they don’t pop up out of the ground like mushrooms when they see me coming and say, “Here I am and take me home.”
When my “anonymous” friend told me the rock tub was probably a hundred miles from where he safely stashed it, I decided to build another sled and improve on my old design.
I love to dry wash old nugget patches found by detector operators, and I have found my fair share of gold dry washing those areas. I have also found a few nuggets using a detector on the bedrock exposed by dry washing the patches.
