What Have You Got to Lose?
November 2016 by Chris RalphIt’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?
It was time to prime the pump and start the engine! Dan’s priming method is to use a small, submersible, 12-volt pump. My priming method is to use a hand-operated diaphragm pump.
I metal detected a number of years before I saw my first nugget peeking out from the dirt before I had scraped or dug for it. This one was in the steep sidewall of a narrow, but deep drywash.
She said a few thoughts did cross her mind at the time; she thought maybe she should have looked more thoroughly for that hand-drawn map to the claim that we had given her the previous year.
…the men sought to “inject false and misleading information about the genuine supply and demand for precious metals futures contracts into the markets, and to deceive other participants”…
Perhaps the most notable thing about skim placers is that they form on the top surface of gravel bars, as opposed to coarser gold placers where the weight of the gold particles allows the gold to settle down on or near bedrock.
The problem is every other nugget hunter and drywash prospector had the same idea. As a result, you can spend days, weeks, and even months detecting these areas and not find a single nugget.
The whole purpose of sampling mineralized ground is to measure the values in a small volume of material that would be representative of a much larger volume of similar material. The key word is representative. Chemical and fire assaying will not accurately represent placer deposits by themselves.
