Dredging Tips and Tricks: A Measure of Water Pump Efficiency
August 2020 by Harry Griffin
…as an academic argument, when mated to the appropriate engine, is the pump really moving water at the rate of 400 GPM?
Over the years, I’ve proved to myself over and over again that I don’t have to wait many weeks after rains before I head out to the goldfields to do some gold digging.
Digging in the right spots will produce excellent results, like this group of nuggets taken by the author while metal detecting during the last few months. The biggest nugget is over an ounce.
I have seen many samples taken originally with an eye toward getting the highest grades possible, but later someone claims that those results represent an average grade of the whole gravel deposit.
My metal detecting hobby began about ten years ago when I bought a used metal detector for about $300. I got it specifically to look for meteorites. It was pretty much worthless, not user friendly, and I did not find anything with it.
Many miners know that lead is very commonly associated with silver values, but the truth is that it is also associated with gold values in many locations as well.
It all occurred when Gus and I returned to a remote placer gold area where we had previously found really good gold. The problem was that it would take about an hour to walk through the desert to get to it.
This past summer, a two-week adventure in Alaska and other gold prospecting trips turned out to be some of my greatest life experiences.
