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.
Walking around the gulch and exploring the upper drainage, picking up different rocks and inspecting them with a good loop, and looking them up in a field guide of rocks and minerals of your region will help you understand how the gold got there.
Just three weeks ago one of our prospecting team members decided to go back to this location on his own. He had a new detector and wanted to try it out some.
In some places valuable ores can be found within the waste material of mine dumps, sorted ore piles, and detrital vein matter at the surface. Though many of these old mine sites can be an excellent source of gold, not all are created equal.
Back in October I read with great interest Chris Ralph’s article on the use of a metal detector while drywashing, and I wholeheartedly agree—I wouldn’t even consider going drywashing without using a metal detector in conjunction...
The 15 rare earth elements were discovered long after the gold rush began to wane, but demand for them only took off over the past 10 years...
The box sat in a hallway and employees began using it for impromptu cricket games, no knowing what it contained.
Once indicators start showing up along or below a contact I start to get excited. When I have shale, and outcroppings of diorite with iron-red, gritty soil and some clay thrown in, I really get lightheaded. I may be a mile away from the nearest diggings but that’s okay. I just found a spot that could provide some nice nugget hunting.
