Prospecting & Detecting
A Long Dry Spell
October 2015 by Don Robinson
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.
Northwestern Alaska Mineral Resources
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.
Fells Flat Gold
My wife Fran and I were brushing and repairing the road to our claim when we were interrupted by a fellow in a pretty yellow Jeep heading out to the local town of Quincy, California.
Selenium, Mercury and Suction Dredging—Studies Contradict CA State Water Resources Board
Federal and state regulatory agencies often cite mercury and methyl mercury in our waterways as a major factor for further restrictions on placer mining, and on suction gold dredge mining, in particular. However, these regulatory agencies are minimizing selenium and its neutralizing effects.
Detecting the Fringe Areas
One prime example is an area that I have talked about in many of my articles. This is a very large area and I will actually describe its location again.
Pros and Cons of Big Detector Coils
Years later I returned with a new detector with a smaller coil and detector technology more sensitive to smaller nuggets. I found my first nugget within five minutes. I had a second five minutes after that.
Following Clues to an Old Mill and Vein Strike
My last update on this adventure was in the April 2012 issue and involved our search for the northern extension of the Cedarberg Mine. At that time we had found it and we were in the process of returning for some detecting when Mother Nature struck with a late rain and snow storm.
Tips on Crevicing for Gold
When everything is still dry, one of my favorite methods of prospecting is using a straw to blow out small cracks and crevices that dot the exposed bedrock along a stream.
