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.
Within the first 3 hours he and I had found pocket after pocket of gold and couldn't wait to tell Levi of our treasure.
Rocks and minerals associated with clay seam gold deposits in southern Oregon are often in sedimentary rock units at least partially metamorphosed into argillite. They are also associated with mafic volcanic rocks, basalts and gabbro that...
It is important to note that discrimination is a type of electronic filtering. The signal is analyzed, and depending on the discrimination setting, identified as either a target to be dug or a target to be ignored.
We split up in order to cover a larger area and found good color almost everywhere. The bedrock was shallow on both sides of the river, but the inside bend was where we concentrated our prospecting.
In October, five of us decided to take an exploration trip into an area called Green Valley. This was perhaps ten miles upstream from where we had gone in September and the difficulty was access. One would think that based on the name it was an easily accessible area not far from a nearby town. This couldn’t be more wrong.
Gold and jade are actually only minor mineral resources for the Northwestern Alaska region as a whole. Modern prospecting has focused more on base metal than precious metal resources.
We soon found that our discovery post and other claim markers were gone and replaced with new posts and a notice of location with an earlier date than had been on our notice of location.
