Dredging Tips and Tricks: T-80 Air Compressor Maintenance
June 2020 by Harry Griffin
The next morning, I retrieved the compressor and again attacked the sticky head bolt. As if by magic (and some applied physics) the head bolt sighed and finally broke loose.
And we eventually reached gold. It was a winding crevice of beautiful white quartz lined with small nuggets and loaded with fine gold. There were flakes and small granular pieces—there had to be a hundred or more.
Your odds of going home with gold will be higher using the discrimination mode, even if you might have misread one of the targets you rejected.
Much more information can be gained from that single source and gives you ideas on the gravels for dry washing or where the nuggets may lie for metal detecting
We’ve had two trips to the deserts of Nevada and explored mines and mill sites, hiked miles of ravines in California, and swung our detector coils over thousands of square yards of bedrock.
It’s accepted knowledge that wet methods will recover more fine gold than dry methods and processing the gravel as a whole will get more gold than only using a metal detector. The question is how much more?
I opted for the underwater portion of the river. All I have to do is float down the river and pick large flakes and small nuggets out of cracks and crevices while staying cool in the summer heat.
Looking for nugget laden bedrock in forested mountain regions, you first need to explore the banks of the gold-bearing streams and look for the bedrock that is exposed as this is your starting point.
